PROSPECTUS SUMMARY

        In this prospectus, the terms "we," "us," "our" and the "Company" refer to Huntsman International LLC, the issuer of the new notes, and its subsidiaries. The following summary highlights selected information from this prospectus and may not contain all the information that is important to you. This prospectus contains information regarding our business and detailed financial information. You should carefully read this entire document.

Our Business

        We are a global manufacturer and marketer of differentiated and commodity chemicals. We manage our business through four segments: Polyurethanes, Performance Products, Pigments and Base Chemicals. We manufacture our products at facilities located primarily in North America, Europe, Asia and Africa and sell our products throughout the world.

Our Products and Segments

        Our business is organized around our four segments: Polyurethanes, Performance Products, Pigments and Base Chemicals. These segments can be divided into two broad categories: differentiated and commodity. We produce differentiated products primarily in our Polyurethanes and Performance Products segments. These products serve diverse end markets and are generally characterized by historical growth in excess of GDP growth resulting from product substitution and new product development, proprietary manufacturing processes and product formulations and a high degree of customer loyalty. Demand for these products tends to be driven by the value-added attributes that they create in our customers' end-use applications. While the demand for these differentiated products is also influenced by worldwide economic conditions and GDP growth, our differentiated products have tended to produce more stable profit margins and higher demand growth rates than our commodity products.

        In our commodity chemical businesses, we produce titanium dioxide derived from titanium-bearing ores in our Pigments segment and petrochemical-based olefins, aromatics and polyolefins products in our Polymers and Base Chemicals segments. Since the coatings industry consumes a substantial portion of titanium dioxide production, seasonal demand patterns in the coatings industry drive the profitability of our Pigments segment; profitability is also driven by industry-wide operating rates, with a lag of up to twelve months due to the effects of stocking and destocking by customers and suppliers. The profitability of our Base Chemicals products is cyclical and has been experiencing a down cycle for the last several years, resulting primarily from significant new capacity additions, a decrease in demand reflecting weak global economic conditions and high raw material costs. Certain industry fundamentals have recently improved and, we believe, point to increased profitability in the markets for the major commodity products that we manufacture.

Our Company

History

        Our Company, Huntsman International LLC, is a Delaware limited liability company. It was formed in 1999 in connection with a transaction between Huntsman International Holdings, LLC ("HIH"), Huntsman Specialty Chemicals Corporation ("Huntsman Specialty") and Imperial Chemical Industries PLC ("ICI"). In that transaction, on June 30, 1999, HIH acquired ICI's polyurethane chemicals, selected petrochemicals and titanium dioxide ("TiO2" or "Tioxide") businesses and Huntsman Specialty's propylene oxide ("PO") business. HIH also acquired the 20% ownership interest of BP Chemicals Limited in an olefins facility located at Wilton, U.K. and certain related assets. HIH then transferred the acquired businesses to us and to our subsidiaries. In August 2000, we completed our acquisition of the Morton global TPU business from The Rohm and Haas Company; in

1

February 2001, we completed our acquisition of the global ethyleneamines business of Dow Chemical Company; and, in April 2001, we completed our acquisition of the Albright & Wilson European surfactants business from Rhodia S.A.

Recent Developments

Sale of TDI Business

        On July 1, 2005, we entered into a binding agreement with BASF Corporation to sell our toluene di-isocyanate ("TDI") business. Pursuant to the agreement, we agreed to transfer our TDI customer list, customer sales contracts and other related assets. Our Geismar, Louisiana-based TDI manufacturing plant will not be sold but will be closed and dismantled. The sale closed on July 6, 2005.

        We expect to incur aggregate charges of approximately $39 million in connection with the sale, including a $37 million loss in the second quarter of 2005, with the remaining $2 million to be recorded by the second quarter of 2006.

Proposed Merger of Huntsman LLC and Huntsman International

        On June 17, 2005, Huntsman Corporation announced that it was soliciting consents from the holders of the outstanding senior secured and unsecured notes of Huntsman LLC ("HLLC") in connection with a proposed merger of HLLC with and into us. Both HLLC and we are currently direct or indirect wholly-owned subsidiaries of Huntsman Corporation, are financed as separate entities and have separate SEC reporting obligations. The merger will simplify Huntsman Corporation's financing and SEC reporting structure and will facilitate cost reductions for Huntsman Corporation's bank credit facilities and other financing arrangements and other organizational efficiencies.

        Huntsman Corporation received the necessary consents in early July and is now seeking to obtain a new secured credit facility for HLLC and us (the "Combined Company"). Huntsman Corporation would expect to obtain the new credit facility and complete the proposed merger during the third quarter of 2005. However, no assurance can be given that the new credit facility will be obtained on terms acceptable to Huntsman Corporation, or at all. If the new credit facility is not obtained, the proposed merger will not occur.

        Huntsman Corporation's 90%-owned subsidiary Huntsman Advanced Materials LLC ("AdMat") is not involved in the proposed merger and will remain a separately financed subsidiary of Huntsman Corporation. However, the consents that Huntsman Corporation received in connection with the proposed merger would also facilitate the merger of AdMat into the Combined Company under certain conditions, should Huntsman Corporation choose to pursue such a merger in the future.

Voluntary Prepayment on Senior Secured Credit Facilities

        On June 6, 2005, we made a $100 million dollar equivalent voluntary prepayment to the term B loan under our senior secured credit facilities. The balance outstanding on our senior secured credit facilities as of March 31, 2005 was $1,235.9 million. After application of this prepayment, the pro forma balance as of March 31, 2005 would have been $1,135.9 million.

Huntsman Corporation Initial Public Offering

        On February 16, 2005, Huntsman Corporation, our ultimate parent corporation, completed an initial public offering of 55,681,819 shares of its common stock sold by Huntsman Corporation and 13,579,546 shares of its common stock sold by a selling stockholder, in each case at a price to the public of $23 per share, and 5,750,000 shares of its 5% mandatory convertible preferred stock sold by Huntsman Corporation at a price to the public of $50 per share. Net proceeds to Huntsman Corporation from the offering were approximately $1,500 million, substantially all of which was used to

2

repay outstanding indebtedness of certain of Huntsman Corporation's subsidiaries, including HMP Equity Holdings Corporation ("HMP"), HLLC and HIH.

Dividend to HIH

        On February 28, 2005, we paid a dividend in the amount of $35 million to HIH. The dividend was used together with proceeds from the Huntsman Corporation initial public offering to redeem the HIH senior discount notes due 2009.

MDI Initiative

        On March 14, 2005, we announced an initiative designed to significantly increase our global capacity for the manufacture of diphenylmethane diisocyanate ("MDI"). The initiative involves expansions at our two major MDI manufacturing facilities located in Geismar, Louisiana and Rozenburg, Netherlands. We expect that the capacity of our Geismar plant will be expanded by 130 million pounds per year to 990 million pounds per year, while the capacity of the Rozenburg plant will be expanded by 220 million pounds per year to 880 million pounds per year. The capacity expansions will be completed in increments beginning in the first quarter of 2005, with final completion expected by late 2006. These expansions are in addition to our previously announced investments in our Chinese MDI joint ventures.

Ownership

        All of our membership interests are owned by HIH. Initially in 1999, HIH was owned 60% by Huntsman Specialty, 30% by ICI and 10% by institutional investors. In 2002, HMP purchased approximately 1% of the HIH membership interests held by an institutional investor. On May 9, 2003, HMP exercised an option and purchased the ICI subsidiary ("Alta One") that held ICI's 30% membership interest in HIH. At that time, HMP also purchased the remaining approximately 9% of the HIH membership interests held by institutional investors. As a result, HMP owned directly, and indirectly through its ownership of Huntsman Specialty and Alta One, 100% of the HIH membership interests.

        In connection with Huntsman Corporation's initial public offering, Huntsman Corporation and certain affiliates completed a series of reorganization transactions. As a result of these reorganization transactions, our Company now is owned 58% by Huntsman Corporation and 42% by Huntsman LLC. The chart below shows our current organizational structure:

        Our principal executive offices are located at 500 Huntsman Way, Salt Lake City, Utah 84108, and our telephone number is (801) 584-5700.

The New Notes

        The terms of the new notes and those of the outstanding old notes are identical in all material respects, except:

(1)

the new notes will have been registered under the Securities Act;



(2)

the new notes will not contain transfer restrictions and registration rights that relate to the old notes; and



(3)

the new notes will not contain provisions relating to the payment of liquidated damages to be made to the holders of the old notes under circumstances related to the timing of the exchange offer.

Failure to Exchange Your Old Notes

        The old notes which you do not tender or we do not accept will, following the exchange offer, continue to be restricted securities. Therefore, you may only transfer or resell them in a transaction registered under or exempt from the Securities Act and all applicable state securities laws. We will issue the new notes in exchange for the old notes under the exchange offer only following the satisfaction of the procedures and conditions described under the caption "The Exchange Offer."

        Because we anticipate that most holders of the old notes will elect to exchange their old notes, we expect that the liquidity of the markets, if any, for any old notes remaining after the completion of the exchange offer will be substantially limited. Any old notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount outstanding of the old notes.

Other Debt

        As of March 31, 2005, we had $2,939.2 million in debt outstanding other than the old notes.

        The indenture governing the notes limits our ability to incur additional debt. Consequently, we would be required to obtain an amendment of the indenture before we incurred any additional debt, other than the types of debt specifically identified in the indenture as permitted. For more information, see "Other Indebtedness and Certain Financing Arrangements" below.

Summary Historical Financial Data

        The summary historical financial data below presents the historical financial data of our Company as of the dates and for the periods indicated. The summary financial and other data as of and for the three months ended March 31, 2005 and for the three months ended March 31, 2004 has been derived from the unaudited financial statements of our Company included elsewhere in this prospectus. The summary financial and other data as of March 31, 2004 has been derived from the unaudited financial statements of our Company. The summary financial and other data as of December 31, 2004 and December 31, 2003, and for each of the three years and the period ended December 31, 2004 has been derived from the audited financial statements of our Company included elsewhere in this prospectus.

        The summary financial data set forth below should be read in conjunction with our audited and unaudited consolidated financial statements, "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Unaudited Pro Forma Financial Data," and "Selected Historical Financial Data" included elsewhere in this prospectus and, in each case, any related notes thereto.

(1)

EBITDA is defined as net income (loss) before interest, income taxes, depreciation and amortization. We believe that EBITDA enhances an investor's understanding of our financial performance and our ability to

11

satisfy principal and interest obligations with respect to our indebtedness. However, EBITDA should not be considered in isolation or viewed as a substitute for net income, cash flow from operations or other measures of performance as defined by generally accepted accounting principles in the U.S. ("GAAP"). Moreover, EBITDA as used herein is not necessarily comparable to other similarly titled measures of other companies due to potential inconsistencies in the method of calculation. Our management uses EBITDA to assess financial performance and debt service capabilities. In assessing financial performance, our management reviews EBITDA as a general indicator of economic performance compared to prior periods. Because EBITDA excludes interest, income taxes, depreciation and amortization, EBITDA provides an indicator of general economic performance that is not affected by debt restructurings, fluctuations in interest rates or effective tax rates, or levels of depreciation and amortization. Accordingly, our management believes this type of measurement is useful for comparing general operating performance from period to period and making certain related management decisions. EBITDA is also used by securities analysts, lenders and others in their evaluation of different companies because it excludes certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be highly dependent on a company's capital structure, debt levels and credit ratings. Therefore, the impact of interest expense on earnings can vary significantly among companies. In addition, the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. As a result, effective tax rates and tax expense can vary considerably among companies. Finally, companies employ productive assets of different ages and utilize different methods of acquiring and depreciating such assets. This can result in considerable variability in the relative costs of productive assets and the depreciation and amortization expense among companies. Our management also believes that our investors use EBITDA as a measure of our ability to service indebtedness as well as to fund capital expenditures and working capital requirements. Nevertheless, our management recognizes that there are material limitations associated with the use of EBITDA in the evaluation of our Company as compared to net income, which reflects overall financial performance, including the effects of interest, income taxes, depreciation and amortization. EBITDA excludes interest expense. Because we have borrowed money in order to finance our operations, interest expense is a necessary element of our costs and ability to generate revenue. Therefore, any measure that excludes interest expense has material limitations. EBITDA also excludes taxes. Because the payment of taxes is a necessary element of our operations, any measure that excludes tax expense has material limitations. Finally, EBITDA excludes depreciation and amortization expense. Because we use capital assets, depreciation and amortization expense is a necessary element of our costs and ability to generate revenue. Therefore, any measure that excludes depreciation and amortization expense has material limitations. Our management compensates for the limitations of using EBITDA by using it to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Our management also uses other metrics to evaluate capital structure, tax planning and capital investment decisions. For example, our management uses credit ratings and net debt ratios to evaluate capital structure, effective tax rate by jurisdiction to evaluate tax planning, and payback period and internal rate of return to evaluate capital investments. Our management also uses trade working capital to evaluate its investment in accounts receivable and inventory, net of accounts payable.

(2)

We have calculated the ratio of earnings to fixed charges according to a formula the SEC requires us to use. This formula defines earnings generally as our pre-tax earnings from operations, less interest expense and defines fixed charges generally as all interest and interest-related payments and accruals. Earnings for each of the three month period ended March 31, 2004 and for the years ended December 31, 2004, 2003, 2002 and 2001 would have to be $32.9 million, $108.3 million, $109.8 million, $28.8 million and $90.2 million higher, respectively, to achieve a one-to-one ratio. The calculation of these ratios is presented at Exhibit 12.1 to the registration statement of which this prospectus forms a part.

RISK FACTORS

        You should carefully consider the risks described below in addition to all other information provided to you in this prospectus before participating in this exchange offer. Any of the following risks could materially and adversely affect our business, financial condition or results of operations.

Risks Related to Our Business

Our available cash and access to additional capital may be limited by our substantial leverage, which could restrict our ability to grow our businesses.

        We have a substantial amount of indebtedness outstanding. As of March 31, 2005, we had total consolidated outstanding indebtedness of approximately $2,939.2 million (including the current portion of long-term debt) and a debt to total capitalization ratio of approximately 70%. We may incur substantial additional debt from time to time for a variety of purposes. Our outstanding debt could have important consequences for our businesses, including:

•

a high degree of debt will make us more vulnerable to a downturn in our businesses, our industry or the economy in general as a significant percentage of our cash flow from operations will be required to make payments on our indebtedness, making it more difficult to react to changes in our business and in market or industry conditions;



•

a substantial portion of our future cash flow from operations may be required to be dedicated to the payment of principal and interest on indebtedness, thereby reducing the funds available for other purposes, including the growth of our businesses;



•

our ability to obtain additional financing may be constrained due to our existing level of debt; and



•

part of our indebtedness is, and any future debt may be, subject to variable interest rates, which makes us vulnerable to increases in interest rates.

        We require substantial capital to finance our operations and continued growth, and we may incur substantial additional debt from time to time for a variety of purposes, including acquiring additional businesses. However, the indentures governing the notes and our outstanding senior notes and senior subordinated notes and our senior secured credit facilities all contain restrictive covenants. Among other things, these covenants limit or prohibit our ability to incur more debt; make prepayments of other debt, including our outstanding senior notes and our senior subordinated notes; pay dividends, redeem stock or make other distributions; issue capital stock; make investments; create liens; enter into transactions with affiliates; enter into sale and leaseback transactions; and merge or consolidate and transfer or sell assets. Additionally, our senior secured credit facilities provide that we will not, and will not permit any of our subsidiaries to, amend, modify or terminate any provisions of the notes or our outstanding senior notes or senior subordinated notes. Also, if we undergo a change of control, the indentures governing the notes and our outstanding senior notes and senior subordinated notes may require us to make an offer to purchase such notes. Under these circumstances, we may also be required to repay indebtedness under our senior secured credit facilities prior to the notes. In this event, we may not have the financial resources necessary to purchase such notes, which would result in an event of default under the indentures governing such notes. See "Description of New Notes."

        We have no scheduled principal payments under our senior secured credit facilities until the second quarter of 2006. Our annual scheduled principal payments under our senior secured credit facilities will be approximately $12.5 million per year. Our $375 million revolving facility matures in September 2008. Our ability to make scheduled payments of principal and interest on, or to refinance, our debt (including the notes) depends on our future performance, which, to a certain extent, is subject to economic, competitive, regulatory and other factors beyond our control. We cannot guarantee that

13

we will have sufficient cash from our operations or other sources to service our debt (including the notes). If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets or seek to obtain additional equity capital or restructure or refinance our debt. We cannot guarantee that such alternative measures would be successful or would permit us to meet our scheduled debt service obligations. In the absence of operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service obligations. We cannot guarantee our ability to consummate any asset sales or that any proceeds from an asset sale would be sufficient to meet the obligations then due.

        If we are unable to generate sufficient cash flow or are otherwise unable to obtain the funds required to meet payments of principal and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in the instruments governing our indebtedness, we could be in default under the terms of those instruments. In the event of a default, a holder of the indebtedness could elect to declare all the funds borrowed under those instruments to be due and payable together with accrued and unpaid interest, the lenders under our senior secured credit facilities could elect to terminate their commitments thereunder and we could be forced into bankruptcy or liquidation. Any of the foregoing consequences could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

If our subsidiaries do not make sufficient distributions to us, then we will not be able to make payment on our debt, including the notes.

        The notes are the exclusive obligations of our company and the guarantors of the notes and not of any of our other subsidiaries. Because a significant portion of our operations are conducted by our subsidiaries, our cash flow and our ability to service indebtedness, including our ability to pay the interest on and principal of the notes at maturity, are dependent to a large extent upon cash dividends and distributions or other transfers from our subsidiaries. In addition, we must first pay amounts due on our senior indebtedness, including our outstanding senior notes, prior to making payments on the notes. Any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to restrictions on dividends or repatriation of earnings under applicable local law, monetary transfer restrictions and foreign currency exchange regulations in the jurisdictions in which our subsidiaries operate, and any restrictions imposed by the current and future debt instruments of our subsidiaries. In addition, payments to us by our subsidiaries are contingent upon our subsidiaries' earnings.

        Our subsidiaries are separate and distinct legal entities and, except for the guarantors of the notes, have no obligation, contingent or otherwise, to pay any amounts due on the notes or to make any funds available therefor, whether by dividends, loans, distributions or other payments, and do not guarantee the payment of interest on, or principal of, the notes. Any right that we have to receive any assets of any of our subsidiaries that are not guarantors upon the liquidation or reorganization of any such subsidiary, and the consequent right of holders of notes to realize proceeds from the sale of their assets, will be structurally subordinated to the claims of that subsidiary's creditors, including trade creditors and holders of debt issued by that subsidiary. The guarantees are unsecured senior subordinated obligations of the guarantors, subordinated to all senior indebtedness of the guarantors, and in the event of the bankruptcy or insolvency of a guarantor, such guarantor's secured lenders will have a prior secured claim to any collateral securing the debt owed to them.

Demand for some of our products is cyclical, and we may experience prolonged depressed market conditions for our products, which may adversely affect our ability to make payments on the notes.

        Historically, the markets for many of our products, particularly our commodity products, have experienced alternating periods of tight supply, causing prices and profit margins to increase, followed

14

by periods of capacity additions, resulting in oversupply and declining prices and profit margins. Several of our markets have experienced conditions of oversupply, and the profitability of our products in these markets has been depressed in recent years. We cannot guarantee that future growth in demand for these products will be sufficient to alleviate any existing or future conditions of excess industry capacity or that such conditions will not be sustained or further aggravated by anticipated or unanticipated capacity additions or other events.

        We derive a substantial portion of our revenue from sales of commodity products, including most of the products of our Base Chemicals and Pigments segments, which generated approximately 47% of our revenue for the year ended December 31, 2004. Due to the commodity nature of these products, competition in these markets is based primarily on price and to a lesser extent on performance, product quality, product deliverability and customer service. As a result, we may not be able to protect our market position for these products by product differentiation and may not be able to pass on cost increases to our customers. Historically, the prices for our commodity products have been cyclical and sensitive to relative changes in supply and demand, the availability and price of feedstocks and general economic conditions. Our other products may be subject to these same factors, but, typically, the impact of these factors is greatest on our commodity products.

We depend on several key customers in our Base Chemicals segment, the loss of whom could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

        Sales of certain of our products, particularly ethylene and propylene in our Base Chemicals segment, are, and historically have been, dependent upon the continued demand from several key customers. This is a common characteristic in the Base Chemicals business. Six customers are expected to account for approximately 73% of our ethylene sales in 2005, and four customers are expected to account for approximately 93% of our propylene sales in 2005. Accordingly, the loss of any of our key Base Chemicals customers could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

        A major customer of our Base Chemicals segment has indicated that, upon termination of our existing contract as of December 31, 2005, it will discontinue purchasing ethylene and propylene from us. We expect this customer to purchase approximately 18% of our 2005 ethylene production and approximately 19% of our 2005 propylene production pursuant to such contract. We believe the expected market conditions in Europe for ethylene and propylene will be such that we will be able to sell, upon expiration of the contract, a substantial portion of the ethylene and propylene such customer historically purchased at prices that generate margins comparable to those historically obtained on sales to such customer. However, if market demand for ethylene or propylene in Europe is weaker than expected, we may experience difficulty in selling the ethylene and propylene historically purchased by such customer, or we may have difficulty selling such ethylene and propylene at comparable margins. Failure to sell such ethylene or propylene, or the failure to receive comparable margins for such ethylene and propylene, could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

        We have announced plans to construct a low-density polyethylene facility at our Wilton, U.K. site with annual production capacity of 900 million pounds. We expect this facility to be operational in late 2007, and, when completed, we expect that it will consume approximately 50% of our annual ethylene output, although we can give you no assurance that it will do so.

15

Significant price volatility or interruptions in supply of our raw materials may result in increased costs that we may be unable to pass on to our customers, which could negatively affect our ability to make payments on the notes.

        The prices of the raw materials that we purchase from third parties are cyclical and volatile. We purchase a substantial portion of these raw materials from third party suppliers, and the cost of these raw materials represents a substantial portion of our operating expenses. The prices for a number of these raw materials generally follow price trends of, and vary with market conditions for, crude oil and natural gas feedstocks, which are highly volatile and cyclical. In recent periods, we have experienced significantly higher crude oil prices, which have resulted in increased raw material prices.

        Although we frequently enter into supply agreements to acquire these raw materials, these agreements typically provide for market-based pricing and provide us only limited protection against price volatility. While we attempt to match cost increases with corresponding product price increases, we are not always able to raise product prices immediately or at all. Timing differences between raw material prices, which may change daily, and contract product prices, which in many cases are negotiated only monthly or less often, have had and may continue to have a negative effect on our cash flow. If any of our suppliers is unable to meet its obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary raw materials from other sources and we may not be able to increase prices for our finished products to recoup the higher raw materials cost. In addition, if any of the raw materials that we use become unavailable within the geographic area from which they are now sourced, then we may not be able to obtain suitable and cost effective substitutes. Any cost increase that we are not able to pass on to our customers or any interruption in supply of raw materials could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

The industries in which we compete are highly competitive, and we may not be able to compete effectively with our competitors that have greater financial resources, which could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

        The industries in which we operate are highly competitive. Among our competitors are some of the world's largest chemical companies and major integrated petroleum companies that have their own raw material resources. Some of these companies may be able to produce products more economically than we can. In addition, some of our competitors have greater financial resources, which may enable them to invest significant capital into their businesses, including expenditures for research and development. If any of our current or future competitors develops proprietary technology that enables them to produce products at a significantly lower cost, our technology could be rendered uneconomical or obsolete. Moreover, certain of our businesses use technology that is widely available. Accordingly, barriers to entry, apart from capital availability, are low in certain product segments of our business, and the entrance of new competitors into the industry may reduce our ability to capture improving profit margins in circumstances where capacity utilization in the industry is increasing. Further, petroleum-rich countries have become more significant participants in the petrochemical industry and may expand this role significantly in the future. Increased competition in any of our businesses could compel us to reduce the prices of our products, which could result in reduced profit margins and loss of market share and have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

Our operations involve risks that may increase our operating costs, which could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

        Although we take precautions to enhance the safety of our operations and minimize the risk of disruptions, our operations are subject to hazards inherent in the manufacturing and marketing of

16

differentiated and commodity chemical products. These hazards include: pipeline leaks and ruptures; explosions; fires; severe weather and natural disasters; mechanical failures; unscheduled downtimes; labor difficulties; transportation interruptions; remediation complications; chemical spills; discharges or releases of toxic or hazardous substances or gases; storage tank leaks; and other risks. Some of these hazards can cause bodily injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties and liabilities. Furthermore, we are subject to present and future claims with respect to workplace exposure, exposure of contractors on our premises as well as other persons located nearby, workers' compensation and other matters.

        We maintain property, business interruption and casualty insurance policies which we believe are in accordance with customary industry practices, but we are not fully insured against all potential hazards and risks incident to our business. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

        In addition, we are subject to various claims and litigation in the ordinary course of business. We maintain insurance to cover many of our potential losses, but we are subject to various self-retentions and deductibles under our insurance. In conjunction with many of our past acquisitions, we have obtained indemnity agreements from the prior owners addressing liabilities that may arise from operations and events prior to our ownership. We are a party to several pending lawsuits and proceedings. It is possible that a judgment could be rendered against us in these cases or others in which we could be uninsured or not covered by indemnity and beyond the amounts that we currently have reserved or anticipate incurring for such matters.

Material weaknesses in our internal controls could result in material misstatements in our financial statements, cause investors to lose confidence in our reported financial information and result in a lower trading price of our securities.

        In connection with the audit of the financial statements of our parent and its subsidiaries (the "Huntsman Companies" or "Group") for the year ended December 31, 2003, the Group's independent registered public accounting firm, or auditors, identified several matters that they deemed to be "material weaknesses" in the Group's internal controls as defined in standards established by the American Institute of Certified Public Accountants. The principal material weakness identified by the auditors was that the Group's controllership function did not have an adequate formal process in place to gather the data required to prepare the financial statements and disclosures required for the numerous financial reporting requirements of the Huntsman Companies. The auditors noted that these material weaknesses had led to restatements of the financial statements of certain of the Huntsman Companies, including us, in recent periods.

        In connection with the audit of the Group's financial statements for the year ended December 31, 2004, the auditors did not identify any matters that they deemed to be material weaknesses. In conducting their audit, however, the auditors did not undertake to audit the Group's internal controls, and thus we cannot give any assurance that they would not have noted additional material weaknesses, or reiterated the material weaknesses described above, had they done so. Nor can we give any assurance that the auditors will not note additional material weaknesses, or reiterate the material weaknesses described above, in future audits of the Group's financial statements. Any such material weaknesses could cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements.

17

        The Group has engaged Ernst & Young LLP to assist the Group's management in its evaluation of the Group's internal controls in preparation for the periodic management evaluations and annual auditor attestation reports regarding the effectiveness of its "internal control over financial reporting" that will be required when the SEC's rules under Section 404 of the Sarbanes-Oxley Act of 2002 become applicable to the Group beginning with its Annual Reports on Form 10-K for the year ending December 31, 2006 to be filed in the first quarter of 2007. We cannot give any assurance, however, that the Group's internal controls will be effective when Section 404 becomes applicable to it. Ineffective internal controls could cause investors to lose confidence in our reported financial information and could result in a lower trading price for our securities.

Our ability to repay our debt may be adversely affected if our joint venture partners do not perform their obligations or we have disagreements with them.

        We conduct a substantial amount of our operations through our joint ventures. Our ability to meet our debt service obligations depends, in part, upon the operation of our joint ventures. If any of our joint venture partners fails to observe its commitments, that joint venture may not be able to operate according to its business plans or we may be required to increase our level of commitment to give effect to those plans. In general, joint venture arrangements may be affected by relations between the joint venture partners. Differences in views among the partners may, for example, result in delayed decisions or in failure to agree on significant matters. Such circumstances may have an adverse effect on the business and operations of the joint ventures, adversely affecting the business and operations of our company. If we cannot agree with our joint venture partners on significant issues, we may experience a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

If we are unable to maintain our relationships with Huntsman LLC then we may not be able to replace on favorable terms our contracts with them or the services and facilities that they provide, if at all.

        We have entered and will continue to enter into certain agreements, including service, supply and purchase contracts with Huntsman LLC. If Huntsman LLC or any of its affiliates fails to perform its obligations under any of these agreements, or if any of these agreements terminate or we are otherwise unable to obtain the benefits thereunder for any reason, there could be a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes if we are unable to obtain similar service, supply or purchase contracts on the same terms from third parties. For example, we have only one operating facility for our production of propylene oxide, which is located in Port Neches, Texas. The facility is dependent on the existing infrastructure and adjacent facilities of Huntsman LLC for certain utilities, raw materials, product distribution systems and safety systems. In addition, we depend upon employees of Huntsman LLC to operate our Port Neches facility. We purchase all of the propylene used in the production of propylene oxide through Huntsman LLC's pipeline, which is the only existing propylene pipeline connected to our propylene oxide facility. If we were required to obtain propylene from another source, we would need to make a substantial investment in an alternative pipeline. This could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

We are subject to many environmental and safety regulations that may result in unanticipated costs or liabilities, which could have a material adverse effect on our business, results of operations and financial condition and on our ability to make payments on the notes.

        We are subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or

18

prohibitions on plant operations, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs or liabilities, which could have a material adverse effect on our business, results of operations, financial condition and liquidity.

        In addition, we could incur significant expenditures in order to comply with existing or future environmental or safety laws. Capital expenditures and costs relating to environmental or safety matters will be subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose requirements on our operations. Therefore, we cannot assure you that capital expenditures and costs beyond those currently anticipated will not be required under existing or future environmental or safety laws.

        Furthermore, we may be liable for the costs of investigating and cleaning up environmental contamination on or from our properties or at off-site locations where we disposed of or arranged for the disposal or treatment of hazardous materials or from disposal activities that pre-dated the purchase of our businesses. We cannot assure you that additional costs and expenditures beyond those currently anticipated will not be incurred to address all such known and unknown situations under existing and future environmental law.

        For additional information, see "Business—Environmental, Health and Safety Matters" below.

Existing or future litigation or legislative initiatives restricting the use of MTBE in gasoline may subject us or our products to environmental liability or materially adversely affect our sales and costs.

        We produce methyl tertiary butyl ether, or MTBE, an oxygenate that is blended with gasoline to reduce vehicle air emissions and to enhance the octane rating of gasoline. The use of MTBE is controversial in the U.S. and elsewhere and may be substantially curtailed or eliminated in the future by legislation or regulatory action. For example, California, New York and Connecticut have adopted rules that prohibit the use of MTBE in gasoline sold in those states as of January 1, 2004. Overall, states that have taken some action to prohibit or restrict the use of MTBE in gasoline account for a substantial portion of the "pre-ban" U.S. MTBE market. Additional phase-outs or other future regulation of MTBE may result in a significant reduction in demand for our MTBE, a material loss in revenues or material increase in compliance costs or expenditures. In addition, a number of lawsuits have been filed, primarily against gasoline manufacturers, marketers and distributors, by persons seeking to recover damages allegedly arising from the presence of MTBE in groundwater. While we have not been named as a defendant in any litigation concerning the environmental effects of MTBE, we cannot provide assurances that we will not be involved in any such litigation or that such litigation will not have a material adverse effect on our business, results of operations, financial condition, liquidity or on our ability to make payments on the notes.

        For additional information, see "Business—Environmental, Health and Safety Matters—MTBE Developments."

Our results of operations may be adversely affected by fluctuations in currency exchange rates and international business risks.

        We conduct a significant portion of our business outside the U.S. Our operations outside the U.S. are subject to risks normally associated with international operations. These risks include the need to convert currencies which may be received for our products into currencies required to pay our indebtedness or into currency in which we purchase raw materials or pay for services, which could result in a gain or loss depending on fluctuations in exchange rates. In addition, we translate our local currency financial results into U.S. dollars based on average exchange rates prevailing during the

19

reporting period or the exchange rate at the end of that period. During times of a strengthening U.S. dollar, our reported international sales and earnings may be reduced because the local currency may translate into fewer U.S. dollars.

        Other risks of international operations include trade barriers, tariffs, exchange controls, national and regional labor strikes, social and political risks, general economic risks and required compliance with a variety of foreign laws, including tax laws and the difficulty of enforcing agreements and collecting receivables through foreign legal systems. The occurrence of these risks could adversely affect the businesses of our international subsidiaries, which could significantly affect their ability to make distributions to us.

Our business is dependent on our intellectual property. If our patents are declared invalid or our trade secrets become known to our competitors, our ability to compete may be adversely affected.

        Proprietary protection of our processes, apparatuses and other technology is important to our business. Consequently, we may have to rely on judicial enforcement of our patents and other proprietary rights. While a presumption of validity exists with respect to patents issued to us in the U.S., there can be no assurance that any of our patents will not be challenged, invalidated, circumvented or rendered unenforceable. Furthermore, if any pending patent application filed by us does not result in an issued patent, or if patents are issued to us, but such patents do not provide meaningful protection of our intellectual property, then our ability to compete may be adversely affected. Additionally, our competitors or other third parties may obtain patents that restrict or preclude our ability to lawfully produce or sell our products in a competitive manner, which could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

        We also rely upon unpatented proprietary know-how and continuing technological innovation and other trade secrets to develop and maintain our competitive position. While it is our policy to enter into confidentiality agreements with our employees and third parties to protect our intellectual property, these confidentiality agreements may be breached, may not provide meaningful protection for our trade secrets or proprietary know-how, or adequate remedies may not be available in the event of an unauthorized use or disclosure of such trade secrets and know-how. In addition, others could obtain knowledge of such trade secrets through independent development or other access by legal means. The failure of our patents or confidentiality agreements to protect our processes, apparatuses, technology, trade secrets or proprietary know-how could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

Loss of key members of our management could adversely affect our business.

        We depend on the continued employment and performance of our senior executives and other key members of management. If any of these individuals resigns or becomes unable to continue in his present role and is not adequately replaced, our business operations could be materially adversely affected. In addition, the achievement of our financial goals requires significant management time and, to the extent that members of senior management are unavailable, for any reason, including allocation of management time to other companies, such as Huntsman LLC and Huntsman Advanced Materials LLC ("AdMat"), that are now or may become part of the Huntsman organization, our business could be adversely affected. We generally do not have employment agreements with, and we do not maintain any "key man" life insurance for, any of our executive officers.

Certain events could result in a change of control or default under our existing indebtedness or the notes.

        Huntsman LLC indirectly owns approximately 42% of the equity interests in our parent HIH. Huntsman LLC issued its senior secured notes, which are secured by, among other things, a pledge of

20

approximately 42% of the equity interests of HIH. Huntsman LLC's credit facilities are also secured by, among other things, a pledge of apprximately 42% of the equity interests of HIH. In the case of an event of default under Huntsman LLC's senior secured notes or its credit facilities, the trustee under the indenture governing the Huntsman LLC senior secured notes, acting on behalf of the holders of the Huntsman LLC senior secured notes, or the lenders under the Huntsman LLC credit facilities, could exercise remedies against the collateral securing the Huntsman LLC senior discount notes or the Huntsman LLC credit facilities, as the case may be, including the pledged equity interests. Sale of the pledged equity interests, whether as a result of foreclosure or in connection with bankruptcy or similar proceedings or otherwise, could result in an event of default under our senior secured credit facilities and a change of control under the indentures governing our senior notes, our senior subordinated notes and the notes offered hereby. In such case, the lenders under our senior secured credit facilities could exercise their rights thereunder, including the acceleration of all amounts outstanding. In addition, the holders of our senior notes and our senior subordinated notes and the notes offered hereby would have the right to require us to repurchase their notes at 101% of the aggregate principal amount. There can be no assurance that we will have funds available to pay all amounts outstanding under our senior secured credit facilities in the event of acceleration or to complete repurchases of such notes.

Terrorist attacks, such as the attacks that occurred on September 11, 2001, the continuing military action in Iraq, general instability in various OPEC member nations, the threat of other attacks or acts of war in the U.S. and abroad and increased security regulations related to our industry could adversely affect our business.

        The attacks of September 11, 2001, and subsequent events, including the continuing military action in Iraq, have caused instability in the U.S. and other financial markets and have led, and may continue to lead, to further armed hostilities, prolonged military action in Iraq, or further acts of terrorism in the U.S. or abroad, which could cause further instability in financial markets. Current regional tensions and conflicts in various OPEC member nations, including the continuing military action in Iraq, have caused, and may cause further, increases in raw material costs, particularly crude oil and natural gas feedstocks, which are used in our operations. The uncertainty surrounding the continuing military action in Iraq and the threat of further armed hostilities or acts of terrorism may impact any or all of our physical facilities and operations, which are located in North America, Europe, Asia, Africa, South America and the Middle East, or those of our customers. Furthermore, the terrorist attacks, subsequent events and future developments in any of these areas may result in reduced demand from our customers for our products. In addition, local, state and federal governments have begun a regulatory process that could lead to new regulations impacting the security of chemical plant locations and the transportation of hazardous chemicals, which could result in higher operating costs. These developments will subject our worldwide operations to increased risks and, depending on their magnitude, could have a material adverse effect on our business, results of operations, financial condition, liquidity and on our ability to make payments on the notes.

Future acquisitions, partnerships and joint ventures may require significant resources and/or result in unanticipated adverse consequences that could adversely affect our business, results of operations and financial condition and on our ability to make payments on the notes.

        In the future we may seek to grow our company and businesses by making acquisitions or entering into partnerships and joint ventures. Any future acquisition, partnership or joint venture may require that we make a significant cash investment, issue stock or incur substantial debt. In addition, acquisitions, partnerships or investments may require significant managerial attention, which may be diverted from our other operations. These capital, equity and managerial commitments may impair the operation of our businesses. Furthermore, any future acquisitions of businesses or facilities could entail a number of additional risks, including:

•

problems with effective integration of operations;

21

•

the inability to maintain key pre-acquisition business relationships;



•

increased operating costs;



•

exposure to unanticipated liabilities; and



•

difficulties in realizing projected efficiencies, synergies and cost savings.

We have incurred indebtedness to finance past acquisitions. We may finance future acquisitions with additional indebtedness. We could face the financial risks associated with incurring additional indebtedness such as reducing our liquidity and access to financing markets and increasing the amount of cash flow required to service such indebtedness, which could adversely affect our ability to make payments on the notes.

Risks Related to the Notes

Despite our current levels of indebtedness, we may incur substantially more debt, which could further increase the risks associated with our substantial indebtedness.

        Although the agreements governing our outstanding indebtedness contain, and the indenture governing the notes contains, restrictions on the incurrence of additional indebtedness by us and our restricted subsidiaries, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness incurred in compliance with these restrictions could be substantial. As of March 31, 2005, we had approximately $367.8 million available for additional revolving borrowings, or, within limits, issuances of letters of credit under our senior secured credit facilities. In addition to amounts that may be borrowed under our senior secured credit facilities, the indenture governing the notes also will allow us and our restricted subsidiaries to borrow significant amounts of money from other sources and will place no restrictions on borrowings by our unrestricted subsidiaries. Also, these restrictions do not prevent us from incurring obligations that do not constitute "indebtedness" as defined in the relevant agreement. If new debt is added to the current debt levels, the related risks that we now face could intensify.

We may incur substantial amounts of additional senior secured and unsecured indebtedness as a result of guarantees of such indebtedness of our direct or indirect parent following an initial public offering of common stock of such parent. Our guarantee of such indebtedness which is secured will be effectively senior to the notes to the extent of the value of the property or assets securing such indebtedness. Our guarantee of unsecured indebtedness will rank pari passu with the notes. The indenture does not contain restrictions on such parent company and in certain circumstances the guarantees that we and the guarantors are permitted to issue in respect of such parent company's debt that may be senior in right of payment to the notes or the guarantees of the notes, as the case may be.

        The indenture provides that we and the guarantors of the notes may provide guarantees of indebtedness of our direct or indirect parent following an initial public offering of common stock of such parent if, among other things, the proceeds of such parent's indebtedness are used to refinance our indebtedness. The amount of such guarantees by us and the guarantors shall be limited to the amount of our indebtedness that is so refinanced plus the amount of premiums and expenses to be paid, in each case in connection with such refinancing of our debt. Furthermore, if our indebtedness that is refinanced ranks senior in right of payment to the notes, then the guarantees that we and the guarantors will be permitted to issue may rank senior in right of payment to the notes or the guarantees of the notes to the same extent. The parent company whose indebtedness we and the guarantors so guarantee will not be governed by the covenants in the indenture governing the notes relating to, among other things, restricted payments and incurrence of indebtedness. There is a significant risk that such parent company's indebtedness, including our and our subsidiaries' guarantees of such parent indebtedness, may be satisfied from the assets of our company and the guarantors. If

22

our or our subsidiaries' guarantees of parent indebtedness rank senior in right of payment to the notes and the guarantees and our parent becomes insolvent, our parent's creditors may assert claims against us or our subsidiaries that are senior in right of payment to claims of holders of the notes. See "Description of New Notes—Certain Covenants—Limitation on Incurrence of Additional Indebtedness," "—Limitation on Restricted Payments," "—Limitation on Liens" and "—Limitations on Transactions with Affiliates."

The instruments governing our debt contain cross default provisions that may cause all of the debt issued under such instruments to become immediately due and payable as a result of a default under an unrelated debt instrument.

        The indentures governing our outstanding senior notes and senior subordinated notes and the notes contain numerous covenants, and the agreements governing our senior secured credit facilities contain numerous covenants and require us to meet certain financial ratios and tests. Our failure to comply with the obligations contained in the indentures governing our outstanding senior notes and senior subordinated notes and the notes, our senior secured credit facilities or other instruments governing our indebtedness could result in an event of default under the applicable instrument, which could result in the related debt and the debt issued under other instruments becoming immediately due and payable. In such event, we would need to raise funds from alternative sources, which funds may not be available to us on favorable terms, on a timely basis or at all. Alternatively, such a default could require us to sell our assets and otherwise curtail operations in order to pay our creditors.

The notes and the subsidiary guarantees are subordinated to our and the subsidiary guarantors' senior debt.

        The notes are our senior subordinated obligations. Accordingly, the notes are subordinated to all of our existing and future senior debt. We expect to incur additional senior debt from time to time in the future. The indenture governing the notes limits, but does not prohibit, the incurrence of other debt by us, including senior debt. As a result of such subordination, upon any distribution to our creditors in a liquidation, dissolution, bankruptcy, reorganization or any similar proceeding by or relating to us or our property, the holders of our senior debt would be entitled to receive payment in full before the holders of the notes would be entitled to receive any payment. In addition, all payments on the notes could be blocked in the event of a default on our senior debt. See "Description of New Notes—Subordination."

        The notes are not secured. The borrowings under our senior secured credit facilities are secured by liens on our assets. If we or any of our subsidiary guarantors liquidates, dissolves or declares bankruptcy, or if payment under the credit agreement or any of our other secured debt is accelerated, our secured lenders would be entitled to exercise the remedies available to a secured lender under applicable law and will have a claim on those assets before the holders of the notes. The guarantees are unsecured senior subordinated obligations of the guarantors, subordinated to all senior indebtedness of the guarantors, and in the event of the bankruptcy or insolvency of a guarantor, such guarantor's secured lenders will have a prior secured claim to any collateral securing the debt owed to them. As of March 31, 2005, we and the subsidiary guarantors have approximately $1,701.2 million of senior debt outstanding to which the notes and the subsidiary guarantees are subordinated, and approximately $367.8 million of additional debt is available for borrowing under our senior secured credit facilities.

The notes are structurally subordinated to all indebtedness of our subsidiaries that are not guarantors of the notes.

        We derive substantially all of our revenue from our consolidated subsidiaries. While certain of our subsidiaries will guarantee the notes, other subsidiaries are not guaranteeing the notes. You will not have any claim as a creditor against our other subsidiaries that are not guarantors of the notes.

23

Accordingly, all obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes. As of March 31, 2005, our non-guarantor subsidiaries had approximately $36.6 million of total indebtedness, excluding intercompany indebtedness owed to us or the guarantors.

We may not have the ability to repurchase notes upon a change of control as required by the indenture.

        Upon the occurrence of certain change of control events, each holder of notes may require us to repurchase all or a portion of its notes at a purchase price equal to 101% of their principal amount plus accrued interest to the date of purchase. Our ability to repurchase the notes upon a change of control is prohibited by our senior secured credit facilities. In any event, we cannot assure you that we will have sufficient funds to repurchase the notes upon a change of control. Our failure to repurchase the notes upon a change of control would result in a default under the indenture governing the notes, which would, in turn, result in a default under our senior secured credit facilities and our outstanding senior notes and senior subordinated notes.

The notes and guarantees may be void, avoided or subordinated under laws governing fraudulent transfers and insolvency.

        We have incurred substantial debt, including our outstanding senior notes and senior subordinated notes and our senior secured credit facilities. Various fraudulent conveyance laws enacted for the protection of creditors may apply to our issuance of the notes and the guarantors' issuance of the guarantees. To the extent that a court were to find that:

        (1)   the notes were issued or a guarantee was incurred with actual intent to hinder, delay or defraud any present or future creditor; or

        (2)   we or a guarantor did not receive fair consideration or reasonably equivalent value for issuing the notes or guarantees;

and that we or a guarantor

        (A)  was insolvent;

        (B)  was rendered insolvent by reason of the issuance of the notes or a guarantee;

        (C)  was engaged or about to engage in a business or transaction for which our or its remaining assets or those of a guarantor constituted unreasonably small capital; or

        (D)  intended to incur, or believed that we or it would incur, debts beyond our or its ability to pay those debts as they matured;

then the court could void the notes and the guarantees or subordinate the notes or the guarantees in favor of our or the guarantor's other creditors. Furthermore, to the extent that the notes or a guarantee were voided as a fraudulent conveyance or held unenforceable for any other reason:

•

claims of holders of the notes against us or a guarantor would be adversely affected;



•

the notes or the guarantees would be effectively subordinated to all obligations of our other creditors or the creditors of the guarantor; and



•

the other creditors would be entitled to be paid in full before any payment could be made on the notes or the guarantees.

There is no established trading market for the new notes, and any market for the new notes may be illiquid.

        The new notes are a new issue of securities with no established trading market. We cannot assure you that a liquid market will develop for the new notes, that you will be able to sell your new notes at

24

a particular time or that the prices that you will receive when you sell will be favorable. We do not intend to apply for listing of the new notes on any U.S. securities exchange or for quotation through an automated dealer quotation system. We do intend to list the euro notes on the Luxemborg Stock Exchange. The liquidity of the trading market in the new notes and the market price quoted for the new notes may be adversely affected by changes in the overall market for high yield securities generally or the interest of securities dealers in making a market in the new notes and by changes in our financial performance or prospects or in the prospects for companies in the chemical industry generally. As a result, you cannot be sure that an active trading market will develop for the new notes. This offer to exchange the new notes for the old notes does not depend upon any minimum amount of old notes being tendered for exchange.

        Unless you are an affiliate of our Company within the meaning of Rule 405 under the Securities Act, you may offer for resale, resell or otherwise transfer new notes without compliance with the registration and prospectus delivery provisions of the Securities Act, so long as you acquired the new notes in the ordinary course of business and have no arrangement or understanding with respect to the distribution of the new notes to be acquired in the exchange offer. If you tender your old notes for the purpose of participating in a distribution of the new notes, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

If you do not exchange your old notes, they may be difficult to resell.

        It may be difficult for you to sell old notes that are not exchanged in this exchange offer, since any old notes not exchanged will remain subject to the restrictions on transfer provided for in Rule 144 under the Securities Act. These restrictions on transfer of your old notes exist because we issued the old notes pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. Generally, the old notes that are not exchanged for new notes in this exchange offer will remain restricted securities and, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in this exchange offer, we do not intend to register the old notes under the Securities Act.

        To the extent any old notes are tendered and accepted in this exchange offer, the trading market, if any, for the old notes that remain outstanding after this exchange offer would be adversely affected due to a reduction in market liquidity.

25

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

        All statements other than statements of historical facts included in this prospectus, including, without limitation, statements regarding our future financial position, business strategy, budgets, projected costs and plans and objectives of management for future operations, are forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as "may", "will", "except", "intend", "estimate", "anticipate", "believe" or "continue" or the negative thereof or variations thereon or similar terminology. Although we believe that the expectations reflected in such forward-looking statements are reasonable, there can be no assurances that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from our expectations are disclosed under "Risk Factors" and elsewhere in this prospectus, including, without limitation, in conjunction with the forward-looking statements included in this prospectus.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

        When we sold the old notes on December 17, 2004, we entered into an exchange and registration rights agreement with the initial purchasers of those notes. Under the exchange and registration rights agreement, we agreed to file the registration statement of which this prospectus forms a part regarding the exchange of the old notes for notes which are registered under the Securities Act. We also agreed to use our reasonable best efforts to cause the registration statement to become effective with the SEC, and to conduct this exchange offer after the registration statement was declared effective. We will use our best efforts to keep the registration statement effective until the exchange offer is completed. The exchange and registration rights agreement provides that we will be required to pay liquidated damages to the holders of the old notes if the exchange offer has not been completed within 45 days after the effective date of the registration statement. A copy of the exchange and registration rights agreement is filed as an exhibit to the registration statement.

Terms of the Exchange Offer

        This prospectus and the accompanying letters of transmittal together constitute the exchange offer. Upon the terms and subject to the conditions set forth in this prospectus and in the letters of transmittal, we will accept for exchange old notes that are properly tendered on or before the expiration date and are not withdrawn as permitted below. The expiration date for this exchange offer is 5:00 p.m., New York City time, on August 26, 2005, or such later date and time to which we, in our sole discretion, extend the exchange offer. The exchange offer, however, will be in effect no longer than 45 days from the date of this prospectus.

        The form and terms of the new notes being issued in the exchange offer are the same as the form and terms of the old notes, except that:

•

the new notes will have been registered under the Securities Act;



•

the new notes will not contain transfer restrictions and registration rights that relate to the old notes; and



•

the new notes will not contain provisions relating to the payment of liquidated damages to be made to the holders of the old notes under circumstances related to the timing of the exchange offer.

        Old dollar notes tendered in the exchange offer must be in denominations of the principal amount of $1,000 or any integral multiple thereof. Old euro notes tendered in the exchange offer must be in denominations of the principal amount of €1,000 or any integral multiple thereof.

        We expressly reserve the right, in our sole discretion:

•

to extend the expiration date;



•

to delay accepting any old notes;



•

if any of the conditions set forth below under "—Conditions to the Exchange Offer" have not been satisfied, to terminate the exchange offer and not accept any notes for exchange; and



•

to amend the exchange offer in any manner.

        We will give oral or written notice of any extension, delay, non-acceptance, termination or amendment as promptly as practicable by a public announcement, and in the case of an extension, no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

        During an extension, all old notes previously tendered will remain subject to the exchange offer and may be accepted for exchange by us. Any old notes not accepted for exchange for any reason will be returned without cost to the holder that tendered them promptly after the expiration or termination of the exchange offer.

How to Tender Old Notes for Exchange

        We have forwarded to you, along with this prospectus, letters of transmittal relating to this exchange offer. Because all of the old notes are held in book-entry accounts maintained by the relevant exchange agent at DTC, Euroclear or Clearstream, Luxembourg, a holder need not submit a letter of transmittal if the holder tenders old notes in accordance with the procedures mandated by DTC's Automated Tender Offer Program ("ATOP") or by Euroclear or Clearstream, Luxembourg, as the case may be. To tender old notes without submitting a letter of transmittal, the electronic instructions sent to DTC, Euroclear or Clearstream, Luxembourg and transmitted to the relevant exchange agent must contain your acknowledgment of receipt of, and your agreement to be bound by and to make all of the representations contained in, the letter of transmittal. In all other cases, a letter of transmittal must be manually executed and delivered as described in this prospectus.

        We have appointed two separate exchange agents in connection with this exchange offer. Wells Fargo Bank, N.A (the "dollar exchange agent") has been appointed as the exchange agent with responsibility for the tender and exchange of all old dollar notes for new dollar notes. Citibank, N.A. (the "euro exchange agent" and, together with the dollar exchange agent, the "exchange agents") has been appointed as the exchange agent with responsibility for the tender and exchange of all old euro notes for new euro notes. Holders of old notes are responsible for knowing which exchange agent is responsible for the type of notes such holder wishes to tender. Any letters of transmittal or other instructions sent by a holder to the wrong exchange agent may be delayed or rejected.

        Only a holder of record of old notes may tender old notes in the exchange offer. To tender in the exchange offer, a holder must comply with the procedures of DTC or Euroclear or Clearstream, Luxembourg, as applicable, and either:

•

complete, sign and date the letter of transmittal, or a facsimile of the letter of transmittal; have the signature on the letter of transmittal guaranteed if the letter of transmittal so requires; and deliver the letter of transmittal or facsimile to the relevant exchange agent prior to the expiration date; or



•

in lieu of delivering a letter of transmittal, comply with the instructions and procedures of DTC or Euroclear or Clearstream, Luxembourg, as the case may be, for the transmittal on behalf of the holder of a computer-generated message to the relevant exchange agent in which the holder of the old notes acknowledges and agrees to be bound by the terms of the letter of transmittal, which computer-generated message shall be received by the relevant exchange agent prior to 5:00 p.m., New York City time, on the expiration date.

        In addition, either:

•

the relevant exchange agent must receive old notes along with the letter of transmittal; or



•

with respect to the old dollar notes, the dollar exchange agent must receive, before expiration of the exchange offer, timely confirmation of book-entry transfer of old dollar notes into the dollar exchange agent's account at DTC, according to the procedure for book-entry transfer described below; or



•

with respect to the old euro notes, the euro exchange agent must receive, before the expiration date, timely confirmation from Euroclear or Clearstream, Luxembourg that the securities account to which the old euro notes are credited has been blocked from and including the day

28

on which the confirmation is delivered to the euro exchange agent and that no transfers will be effected in relation to such old euro notes at any time after such date.

        To be tendered effectively, the appropriate exchange agent must receive any physical delivery of the letter of transmittal and other required documents at such exchange agent's address set forth below under the caption "—Exchange Agents" before expiration of the exchange offer. To receive confirmation of valid tender of old notes, a holder should contact the relevant exchange agent at the corresponding telephone number listed under the caption "—Exchange Agents".

        The tender by a holder that is not withdrawn before expiration of the exchange offer will constitute an agreement between that holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. Only a registered holder of old notes may tender the old notes in the exchange offer. If a holder completing a letter of transmittal tenders less than all of the old notes held by such holder, such tendering holder should fill in the applicable box of the letter of transmittal. The amount of old notes delivered to the exchange agent will be deemed to have been tendered, unless otherwise indicated.

        If old notes, the letter of transmittal or any other required documents are physically delivered to an exchange agent, the method of delivery is at the holder's election and risk. Rather than mail these items, we recommend that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to such exchange agent before expiration of the exchange offer. Holders should not send the letter of transmittal or old notes to us. Holders may request their respective brokers, dealers, commercial banks, trust companies or other nominees to effect the above transactions for them.

        Any beneficial owner whose old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct it to tender on the owner's behalf. If the beneficial owner wishes to tender on its own behalf, it must, prior to completing and executing the letter of transmittal and delivering its old notes, either:

•

make appropriate arrangements to register ownership of the old notes in the owner's name; or



•

obtain a properly completed bond power from the registered holder of old notes.

        The transfer of registered ownership may take considerable time and may not be completed prior to the expiration date.

        If the applicable letter of transmittal is signed by the record holder(s) of the old notes tendered, the signature must correspond with the name(s) written on the face of the old note without alteration, enlargement or any change whatsoever. If the applicable letter of transmittal is signed by a participant in DTC or Euroclear or Clearstream, Luxembourg, as applicable, the signature must correspond with the name as it appears on the security position listing as the holder of the old notes.

        Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed unless the old notes surrendered for exchange are tendered:

        (1)   by a holder of old notes who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the letter of transmittal; or

        (2)   for the account of an "eligible institution."

        An "eligible institution" is a financial institution, including most banks, savings and loan associations and brokerage houses, that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program.

29

        If signatures on a letter of transmittal or notice of withdrawal are required to be guaranteed, the guarantor must be an eligible institution. If old notes are registered in the name of a person other than the signer of the letter of transmittal, the old notes surrendered for exchange must be endorsed by, or accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by us in our sole discretion, duly executed by the registered holder with the holder's signature guaranteed by an eligible institution.

        If a person or persons other than the registered holder or holders of the old notes tendered for exchange signs the letter of transmittal, the tendered notes must be endorsed or accompanied by appropriate powers of attorney, in either case signed exactly as the name or names of the registered holder or holders that appear on the old notes.

        If trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity sign the letter of transmittal or any old notes or any power of attorney, such persons should so indicate when signing, and you must submit proper evidence satisfactory to us of such person's authority to so act unless we waive this requirement.

        We will determine all questions as to the validity, form, eligibility (including time of receipt) and acceptance of old notes tendered for exchange in our sole discretion. Our determination will be final and binding. We reserve the absolute right to:

        (1)   reject any and all tenders of any old note improperly tendered;

        (2)   refuse to accept any old note if, in our judgment or the judgment of our counsel, acceptance of the old note may be deemed unlawful; and

        (3)   waive any defects or irregularities or conditions of tender as to any particular old note either before or after the expiration date, including the right to waive the ineligibility of any holder who seeks to tender old notes in the exchange offer.

        Our interpretation of the terms and conditions of tender as to any particular old note either before or after the expiration date, including the letter of transmittal and the instructions to it, will be final and binding on all parties. Holders must cure any defects and irregularities in connection with tenders of old notes for exchange within such reasonable period of time as we will determine, unless we waive such defects or irregularities. Neither we, the exchange agents nor any other person shall be under any duty to give notification of any defect or irregularity with respect to any tender of old notes for exchange, nor shall any of us incur any liability for failure to give such notification.

        By tendering, each holder will represent to us, among other things, that the person acquiring new notes in this exchange offer is obtaining them in the ordinary course of its business, whether or not such person is the holder, and that neither the holder nor such other person has any arrangement or understanding with any person to participate in the distribution of the new notes issued in this exchange offer. If any holder or any such other person is an "affiliate," as defined under Rule 405 of the Securities Act, of our company, or is engaged in or intends to engage in or has an arrangement or understanding with any person to participate in a distribution of such new notes to be acquired in this exchange offer, such holder or any such other person:

        (1)   may not rely on the applicable interpretations of the staff of the SEC; and

        (2)   must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

        Each broker-dealer who acquired its old notes as a result of market-making activities or other trading activities and thereafter receives new notes issued for its own account in this exchange offer, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes issued in this exchange offer. The letters of transmittal state that by so acknowledging and by delivering

30

a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. See "Plan of Distribution" for a discussion of the exchange and resale obligations of broker-dealers in connection with this exchange offer.

Acceptance of Old Notes for Exchange; Delivery of New Notes

        Upon satisfaction or waiver of all of the conditions to this exchange offer, we will accept, promptly after the expiration date, all old notes properly tendered and will issue the new notes registered under the Securities Act. For purposes of this exchange offer, we shall be deemed to have accepted properly tendered old notes for exchange when, as and if we have given oral or written notice to the exchange agent, with written confirmation of any oral notice to be given promptly thereafter. See "—Conditions to the Exchange Offer" for a discussion of the conditions that must be satisfied before we accept any old notes for exchange.

        For each old note accepted for exchange, the holder will receive a new note registered under the Securities Act having a principal amount equal to, and in the denomination of, that of the surrendered old note. Accordingly, registered holders of new notes on the relevant record date for the first interest payment date following the consummation of this exchange offer will receive interest accruing from the most recent date to which interest has been paid or, if no interest has been paid on the old notes, from December 17, 2004. Old notes that we accept for exchange will cease to accrue interest from and after the date of consummation of this exchange offer. Under the exchange and registration rights agreement, we may be required to make additional payments in the form of liquidated damages to the holders of the old notes under circumstances relating to the timing of this exchange offer.

        In all cases, we will issue new dollar notes in this exchange offer for old dollar notes that are accepted for exchange only after the dollar exchange agent timely receives:

        (1)   certificates for such old dollar notes or a timely book-entry confirmation of such old dollar notes into the dollar exchange agent's account at the book entry transfer facility;

        (2)   a properly completed and duly executed letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message; and

        (3)   all other required documents.

        In all cases, we will issue new euro notes in this exchange offer for old euro notes that are accepted for exchange only after the euro exchange agent timely receives:

        (1)   a timely confirmation from Euroclear or Clearstream, Luxembourg that the securities account to which the old euro notes are credited has been blocked;

        (2)   a properly completed and duly executed letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message; and

        (3)   all other required documents.

        If for any reason set forth in the terms and conditions of this exchange offer we do not accept any tendered old notes, or if a holder submits old notes for a greater principal amount than the holder desires to exchange, we will return such unaccepted or non-exchanged notes without cost to the tendering holder. In the case of old dollar notes tendered by book-entry transfer into the dollar exchange agent's account at DTC, such non-exchanged old dollar notes will be credited to an account maintained with DTC promptly after the expiration or termination of this exchange offer. In the case of old euro notes tendered in accordance with the blocking procedures of Euroclear or Clearstream, Luxembourg, the old euro notes will be returned to their holder by cancellation of the blocking instruction in accordance with the standard operating procedures of Euroclear or Clearstream, Luxembourg promptly after the expiration or termination of this exchange offer.

31

DTC Book Entry Transfers

        The dollar exchange agent will make a request to establish an account at DTC with respect to old dollar notes for purposes of this exchange offer promptly upon receipt of this prospectus. Any financial institution that is a participant in DTC's systems must make book-entry delivery of old dollar notes by causing DTC to transfer those old dollar notes into the dollar exchange agent's account at DTC in accordance with DTC's electronic Automated Tender Offer Program procedures for such transfer. Such participant should transmit its acceptance to DTC on or prior to the expiration date or comply with the guaranteed delivery procedures described below. DTC will verify such acceptance, execute a book-entry transfer of the tendered old dollar notes into the dollar exchange agent's account at DTC and then send to the dollar exchange agent confirmation of such book-entry transfer. The confirmation of such book-entry transfer will include an agent's message confirming that DTC has received an express acknowledgment from such participant that such participant has received and agrees to be bound by the letter of transmittal and that we may enforce the letter of transmittal against such participant. Delivery of new dollar notes may be effected through book-entry transfer at DTC, as applicable. However, the letter of transmittal or facsimile thereof, with any required signature guarantees, or an agent's message, and any other required documents, must be transmitted to and received by the dollar exchange agent at the address set forth below under "—The Exchange Agents" on or prior to the expiration date or comply with the guaranteed delivery procedures described below.

Euroclear and Clearstream, Luxembourg Procedures for Blocking Instructions

        The registered holder of the old euro notes on the records of Euroclear or Clearstream, Luxembourg must, unless otherwise instructed by Euroclear or Clearstream Luxembourg, instruct Euroclear or Clearstream, Luxembourg to block the securities in the account in Euroclear or Clearstream, Luxembourg to which such old euro notes are credited. In order for the exchange offer to be accepted, the euro exchange agent must have received, prior to the expiration date, a confirmation from Euroclear or Clearstream, Luxembourg that the securities account of old euro notes tendered has been blocked from and including the day on which the confirmation is delivered to the euro exchange agent and that no transfers will be effected in relation to the old euro notes at any time after such date. Old euro notes should be blocked in accordance with the procedures of Euroclear or Clearstream, Luxembourg, as the case may be. The exchange of the old euro notes so tendered will only be made after a timely receipt by the euro exchange agent of an agent's message and any other documents required by the letter of transmittal. The term "agent's message" means a message, transmitted by Euroclear or Clearstream, Luxembourg and received by the euro exchange agent which states that Euroclear or Clearstream, Luxembourg has received an express acknowledgment from a participant tendering old euro notes that the participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce that agreement against the participant.

        These instructions are subject to the rules and procedures of Euroclear and Clearstream, Luxembourg, which are subject to change. Holders of old euro notes must comply with any and all instructions received from Euroclear and Clearstream, Luxembourg.

Guaranteed Delivery Procedures

        If a registered holder of old dollar notes desires to tender the old dollar notes, and the old dollar notes are not immediately available, or time will not permit the holder's old dollar notes or other required documents to reach the dollar exchange agent before the expiration date, or the procedure for book-entry transfer described above cannot be completed on a timely basis, a tender may nonetheless be made if:

•

the tender is made through an eligible institution;

32

•

prior to the expiration date, the dollar exchange agent received from an eligible institution a properly completed and duly executed letter of transmittal, or a facsimile of the letter of transmittal, and notice of guaranteed delivery, substantially in the form provided by us, by facsimile transmission, mail or hand delivery,

        (1)   stating the name and address of the holder of old dollar notes and the amount of old dollar notes tendered;

        (2)   stating that the tender is being made; and

        (3)   guaranteeing that within three New York Stock Exchange trading days after the expiration date, the certificates for all physically tendered old dollar notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and any other documents required by the letter of transmittal will be deposited by the eligible institution with the dollar exchange agent; and

•

the certificates for all physically tendered old dollar notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and all other documents required by the letter of transmittal, are received by the exchange dollar agent within three New York Stock Exchange trading days after the expiration date.

Withdrawal Rights

        You may withdraw tenders of your old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

        For a withdrawal to be effective, you must send a written notice of withdrawal to the appropriate exchange agent at such exchange agent's corresponding address set forth below under "—The Exchange Agents." Any such notice of withdrawal must:

        (1)   specify the name of the person having tendered the old notes to be withdrawn;

        (2)   identify the old notes to be withdrawn, including the principal amount of such old notes; and

        (3)   where certificates for old notes are transmitted, specify the name in which old notes are registered, if different from that of the withdrawing holder.

        If certificates for old notes have been delivered or otherwise identified to an exchange agent, then, prior to the release of such certificates the withdrawing holder must also submit the serial numbers of the particular certificates to be withdrawn and signed notice of withdrawal with signatures guaranteed by an eligible institution unless such holder is an eligible institution. If old notes have been tendered pursuant to the procedure for book-entry transfer or the blocking instructions described above, any notice of withdrawal must specify the name and number of the account at DTC or Euroclear or Clearstream, Luxembourg, as applicable, to be credited with the withdrawn old notes and otherwise comply with the procedures of such facility. We will determine all questions as to the validity, form and eligibility (including time of receipt) of such notices and our determination will be final and binding on all parties. Any tendered old notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of this exchange offer. Any old notes tendered for exchange that are not exchanged for any reason will be returned to the holder without cost to such holder. In the case of old notes tendered by book-entry transfer into the exchange agent's account at DTC, such old notes will be credited to an account maintained with DTC for the old notes as soon as practicable after withdrawal, rejection of tender or termination of this exchange offer. In the case of old euro notes tendered in accordance with the blocking procedures of Euroclear or Clearstream, Luxembourg, the old euro notes will be returned to their holder by cancellation of the blocking instruction in accordance with the standard operating procedures of Euroclear or Clearstream, Luxembourg as soon as practicable after

33

withdrawal, rejection of tender or termination of this exchange offer. Properly withdrawn old notes may be re-tendered by following one of the procedures described under "—How to Tender Old Notes for Exchange" above at any time on or prior to 5:00 p.m., New York City time, on the expiration date.

Conditions to the Exchange Offer

        Notwithstanding any other provision of this exchange offer, we will not be required to accept for exchange, or to issue new notes in this exchange offer for any old notes, and we may terminate or amend this exchange offer, if at any time before the expiration of this exchange offer:

        (1)   any federal law, statute, rule or regulation shall have been adopted or enacted which, in our judgment, would reasonably be expected to impair our ability to proceed with this exchange offer;

        (2)   any stop order shall be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended;

        (3)   there shall occur a change in the current interpretation by the staff of the SEC which permits the new notes issued in this exchange offer in exchange for the old notes to be offered for resale, resold and otherwise transferred by such holders, other than broker-dealers and any such holder which is an "affiliate" of our company within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such new notes acquired in this exchange offer are acquired in the ordinary course of such holder's business and such holder has no arrangement or understanding with any person to participate in the distribution of such new notes issued in this exchange offer;

        (4)   there has occurred any general suspension of or general limitation on prices for, or trading in, securities on any national exchange or in the over-the-counter market;

        (5)   any governmental agency creates limits that adversely affect our ability to complete this exchange offer; or

        (6)   there shall occur any declaration of war, armed hostilities or other similar international calamity directly or indirectly involving the United States, or the worsening of any such condition that existed at the time that we commence this exchange offer.

        The non-occurrence of each of the preceding events is a condition to this exchange offer. We expressly reserve the right to amend or terminate this exchange offer upon the occurrence of any of these events. The conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to them. We may waive the preceding conditions in whole or in part at any time and from time to time in our sole discretion prior to the expiration of this exchange offer. If we do so, this exchange offer will remain open for at least three (3) business days following any waiver of the preceding conditions and, if we determine that any waiver constitutes a material change to the terms of this exchange offer, this exchange offer will remain open for at least five (5) business days following any such waiver. Our failure at any time to exercise the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which we may assert at any time and from time to time, except that all conditions to this exchange offer must be satisfied or waived by us prior to the expiration of this exchange offer. We will give oral or written notice or public announcement of any waiver by us of any condition and any related amendment, termination or extension of this exchange offer. In the case of any extension, such oral or written notice or public announcement will be issued no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date.

34

The Exchange Agents

        As explained above, we have appointed two separate exchange agents in connection with this exchange offer. Wells Fargo Bank, N.A has been appointed as the dollar exchange agent and is responsible for the tender and exchange of all old dollar notes for new dollar notes. Citibank, N.A. has been appointed as the euro exchange agent and is responsible for the tender and exchange of all old euro notes for new euro notes. All executed letters of transmittal should be directed to the appropriate exchange agent at the address set forth below corresponding to such exchange agent. You should direct questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for notices of guaranteed delivery to the relevant exchange agent addressed as follows:

        Delivery of the letter of transmittal to the wrong exchange agent, to an address other than as set forth above, or transmission of such letter of transmittal via facsimile other than as set forth above, does not constitute a valid delivery of such letter of transmittal.

35

Fees and Expenses

        We will not make any payment to brokers, dealers or others soliciting acceptance of this exchange offer, except for reimbursement of mailing expenses.

Accounting Treatment

        We will not recognize any gain or loss for accounting purposes upon the consummation of this exchange offer. We will amortize the expense of this exchange offer over the term of the new notes in accordance with accounting principles generally accepted in the United States of America.

Transfer Taxes

        You will not be obligated to pay any transfer taxes in connection with the tender of your old notes in this exchange offer. If, however, new notes are to be delivered to, or are to be issued in the name of, any person other than the holder of the old notes tendered, or if a transfer tax is imposed for any reason other than the exchange of old notes in connection with this exchange offer, then you must pay any such transfer taxes, whether imposed on the registered holder or on any other person. If satisfactory evidence of payment of, or exemption from, such taxes is not submitted with the letter of transmittal, the amount of such transfer taxes will be billed directly to you.

Consequences of Failing to Exchange Old Notes

        Holders who desire to tender their old notes in exchange for new notes registered under the Securities Act should allow sufficient time to ensure timely delivery. Neither of the exchange agents nor our Company is under any duty to give notification of defects or irregularities with respect to the tenders of old notes for exchange.

        Old notes that are not tendered or are tendered but not accepted will, following the consummation of this exchange offer, continue to be subject to the provisions in the indenture regarding the transfer and exchange of the old notes and the existing restrictions on transfer set forth in the legend on the old notes and in the offering memorandum dated December 3, 2004, relating to the old notes. Except in limited circumstances with respect to specific types of holders of old notes, we will have no further obligation to provide for the registration under the Securities Act of such old notes. In general, old notes, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not currently anticipate that we will take any action to register the untendered old notes under the Securities Act or under any state securities laws.

        Upon completion of this exchange offer, holders of the old notes will not be entitled to any further registration rights under the exchange and registration rights agreement, except under limited circumstances.

        Holders of the new notes and any old notes which remain outstanding after consummation of this exchange offer will vote together as a single class for purposes of determining whether holders of the requisite percentage of the class have taken certain actions or exercised certain rights under the indenture.

Consequences of Exchanging Old Notes

        Based on interpretations of the staff of the SEC, as set forth in no-action letters to third parties, we believe that the new notes may be offered for resale, resold or otherwise transferred by holders of such notes, other than by any holder which is a broker-dealer or an "affiliate" of our Company within the meaning of Rule 405 under the Securities Act. The new notes may be offered for resale, resold or

36

otherwise transferred without compliance with the registration and prospectus delivery provisions of the Securities Act, if:

        (1)   the new notes are acquired in the ordinary course of such holder's business; and

        (2)   such holder has no arrangement or understanding with any person to participate in the distribution of the new notes.

        However, the SEC has not considered this exchange offer in the context of a no-action letter and we cannot guarantee that the staff of the SEC would make a similar determination with respect to this exchange offer as in such other circumstances.

        Each holder, other than a broker-dealer, must furnish a written representation, at our request, that:

        (1)   it is not an affiliate of ours;

        (2)   it is not engaged in, and does not intend to engage in, a distribution of the new notes and has no arrangement or understanding to participate in a distribution of the new notes;

        (3)   it is acquiring the new notes in the ordinary course of its business; and

        (4)   it is not acting on behalf of a person who could not make representations (1)-(3).

        Each broker-dealer that receives new notes in this exchange offer for its own account in exchange for old notes must acknowledge that it acquired such old notes as a result of market-making or other trading activities and that it will deliver a prospectus in connection with any resale of the new notes. See "Plan of Distribution" for a discussion of the exchange and resale obligations of broker-dealers in connection with this exchange offer.

        In addition, to comply with state securities laws of certain jurisdictions, the new notes may not be offered or sold in any state unless they have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with by the holders selling the new notes. We have agreed in the exchange and registration rights agreement that, prior to any public offering of transfer restricted securities, we will register or qualify the transfer restricted securities for offer or sale under the securities laws of any jurisdiction requested by a holder. Unless a holder requests, we currently do not intend to register or qualify the sale of the new notes in any state where an exemption from registration or qualification is required and not available. "Transfer restricted securities" means each old note until:

        (1)   the date on which such old note has been exchanged by a person other than a broker-dealer or an affiliate for a new note;

        (2)   following the exchange by a broker-dealer in this exchange offer of an old note for a new note, the date on which the new note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of this prospectus;

        (3)   the date on which such old note has been effectively registered under the Securities Act and disposed of in accordance with a shelf registration statement that we file in accordance with the exchange and registration rights agreement; or

        (4)   the date on which such old note is distributed to the public in a transaction under Rule 144 of the Securities Act.

USE OF PROCEEDS

        We will not receive any cash proceeds from the issuance of the new notes. In consideration for issuing the new notes as contemplated in this prospectus, we will receive in exchange old notes in like

37

principal amount, which will be cancelled and as such will not result in any increase in our indebtedness.

        The aggregate net proceeds received by us from the sale of the old notes, after deducting the initial purchasers' discounts and commissions and offering expenses, were approximately 355 million U.S. dollar equivalents in cash. We used all of the net proceeds to redeem part of our outstanding 10.125% senior subordinated notes due 2009.

RATIO OF EARNINGS TO FIXED CHARGES

        The following table shows our consolidated ratio of earnings to fixed charges for the periods indicated:

(a)

We have calculated the ratio of earnings to fixed charges according to a formula the SEC requires us to use. This formula defines earnings generally as our pre-tax earnings from operations, less interest expense and defines fixed charges generally as all interest and interest-related payments and accruals. Earnings for each of the three month period ended March 31, 2004 and for the years ended December 31, 2004, 2003, 2002 and 2001 would have to be $32.9 million, $108.3 million, $109.8 million, $28.8 million and $90.2 million higher, respectively, to achieve a one-to-one ratio. The calculation of these ratios is presented at Exhibit 12.1 to the registration statement of which this prospectus forms a part.

38

CAPITALIZATION

        The following table sets forth our cash and capitalization as of March 31, 2005. The information presented below should be read in conjunction with our consolidated financial statements, "Use of Proceeds," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Selected Historical Financial Data" included in this prospectus and, in each case, any related notes thereto. We will not receive any cash proceeds from the issuance of the new notes. In consideration for issuing the new notes as contemplated in this prospectus, we will receive in exchange old notes in like principal amount, which will be cancelled and as such will not result in any increase in our capitalization.

(a)

Excludes off-balance sheet indebtedness associated with our accounts receivable securitization program of approximately $202 million in U.S. dollar equivalents, consisting of medium term notes and commercial paper issued by a non-consolidated special purpose entity.

        The summary financial data set forth below should be read in conjunction with the audited consolidated financial statements of the Company, "Management's Discussion and Analysis of Financial Condition and Results of Operations," and "Selected Historical Financial Data" included elsewhere in this prospectus and, in each case, any related notes thereto.

        The following condensed consolidating financial statements present, in separate columns, financial information for the following: Huntsman International LLC (on a parent only basis), with our investment in subsidiaries recorded under the equity method; the HI Guarantors on a combined, and where appropriate, consolidated basis; and the non-guarantors on a combined, and where appropriate, consolidated basis. Additional columns present eliminating adjustments and consolidated totals as of March 31, 2005 and December 31, 2004 and for the three months ended March 31, 2005 and 2004. There are no contractual restrictions limiting transfers of cash from guarantor subsidiaries to us. Each of the HI Guarantors is 100% owned by us and has fully and unconditionally guaranteed the notes, the HI Senior Notes and the HI Subordinated Notes on a joint and several basis. We have not presented separate financial statements and other disclosures for each of the HI Guarantors because management believes that such information is not material to investors.
