Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity Risk Management and Strategy We recognize the importance of developing, implementing and maintaining cybersecurity measures to safeguard our information systems, shield our operational technologies in our manufacturing plants and protect the confidentiality, integrity and availability of our data. We have a qualitative cybersecurity risk management program within our Enterprise Information Security function to promote a company-wide culture of cybersecurity risk management for our information technology and operational technology. This program supports cybersecurity considerations as part of our decision-making processes. Our Enterprise Information Security team works closely with our global information technology organization (“Global IT”), operational technology teams and business units to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. We are aligned with the U.S. National Institute of Standards and Technology Cybersecurity Framework, against which we periodically assess our readiness. Recognizing the complexity and evolving nature of cybersecurity threats, we engage with a range of external experts, including cybersecurity assessors, consultants and auditors, in evaluating and testing our cybersecurity posture. These partnerships enable us to leverage specialized knowledge and insights in the development of our cybersecurity program consistent with industry best practices. Our collaboration with these third parties includes regular audits, threat assessments and consultation on security enhancements. Because we are aware of the risks associated with third parties, we have implemented a third-party security risk management program to oversee and manage these risks. We conduct security assessments of third-party providers contracted by Global IT before engagement and maintain ongoing monitoring to ensure compliance with our cybersecurity standards. The program includes tools and services, which continuously monitor third parties for potential security concerns, data leaks and cyber posture, as well as periodic renewals of due diligence commensurate with their risk. This approach is designed to mitigate risks related to data breaches or other security incidents originating from these third parties. As of the date hereof, we have not identified any cybersecurity threats or previous cybersecurity incidents that have materially affected, or are reasonably likely to materially affect, our business strategy, results of operations or financial condition. However, despite our efforts, we cannot eliminate all risks from cybersecurity threats or provide assurances that we have not experienced undetected cybersecurity incidents. For additional information about these risks, see “Part I. Item 1A. Risk Factors.”

Cybersecurity Risk Board of Directors Oversight [Text Block]	Cybersecurity Governance The Board of Directors is aware of the importance of managing risks associated with cybersecurity threats. The Board of Directors has established oversight mechanisms for effective governance in managing risks associated with cybersecurity threats, because they recognize the significance of these threats to our operational integrity and stakeholder confidence. The Audit Committee is responsible for the Board of Directors’ oversight of cybersecurity risks. The Audit Committee is composed of board members with diverse expertise including, cyber operations, risk management, technology and finance, equipping them to oversee cybersecurity risks effectively. The Audit Committee reviews our cybersecurity programs and the effectiveness of its risk management strategies. This review helps management identify areas for improvement and align our cybersecurity program with the overall risk management framework. The Chief Information Officer (“CIO”) plays a pivotal role in informing the Audit Committee on cybersecurity risks. The CIO provides briefings to the Audit Committee on a quarterly basis. These briefings encompass a broad range of topics, including: ● current cybersecurity landscape and emerging threats; ● status of ongoing cybersecurity initiatives and strategies; ● incident reports and learnings from any cybersecurity events; and ● compliance with regulatory requirements and industry standards. In addition to our scheduled meetings, select members of the Audit Committee and CIO maintain an ongoing dialogue regarding potential cybersecurity threats and mitigation strategies and updates to our cybersecurity posture. The Audit Committee oversees strategic decisions related to our cybersecurity program, offering guidance and approving investments in major initiatives. This ongoing oversight enables cybersecurity considerations to be integrated into our broader strategic planning objectives. Reporting to our CIO, our cybersecurity function is led by our Chief Information Security Officer (“CISO”). The CISO manages a team of cybersecurity professionals and third-party support functions with broad experience and expertise, including in cybersecurity threat assessments and detection, mitigation technologies, cybersecurity training, incident response, cyber forensics, insider threats and regulatory compliance. Our CISO and CIO are regularly informed about the latest developments in cybersecurity, including potential threats and innovative risk management techniques, for the effective prevention, detection, mitigation and remediation of cybersecurity incidents. The CISO implements and oversees processes for the regular monitoring of our information systems. This includes the deployment of security measures and regular system audits to identify potential vulnerabilities. In the event of a cybersecurity incident, we have an incident response plan that includes immediate actions to contain and eradicate the threat, mitigate the impact, and long-term strategies for remediation and prevention of future incidents. The CIO regularly informs the Chief Executive Officer and management regarding cybersecurity risks and incidents, so they are kept abreast of the cybersecurity posture and potential risks. Significant cybersecurity matters and strategic risk management decisions are reported to the Audit Committee.

Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold.

Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. F oreign urrency ranslation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss.

N et ncome er hare ttributable to untsman orporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as potential dilutive securities. Diluted income per share is computed using the treasury stock method for all stock-based awards. In periods with reported loss from continuing operations attributable to Huntsman Corporation, all stock-based awards are generally deemed anti-dilutive and would be excluded from the calculation of diluted income per share from continuing operations, discontinued operations and net income regardless of whether there is income or loss from discontinued operations and net income.

All intercompany accounts and transactions have been eliminated. P roperty, lant and quipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives or lease term as follows: In years Buildings 10 - 40 Plant and equipment 3 - 30 Furniture, fixtures and leasehold improvements 5 - 20 Interest expense capitalized as part of plant and equipment was $7 million, $6 million and $7 million for the years ended December 31, 2024, 2023 2022 Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired. R evenue ecognition We generate substantially all of our revenue through product sales in the open market and long-term supply agreements in which revenue is recognized at a point in time. At contract inception, we assess the goods and services, if any, promised in our contracts and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In substantially all cases, a contract has a single performance obligation to deliver a promised good to the customer. Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. We have elected to account for all shipping and handling activities as fulfillment costs. We have also elected to expense commissions when incurred as the amortization period of the commission asset that we would have otherwise recognized is less than one The amount of consideration we receive and revenue we recognize is based upon the terms stated in the sales contract, which may not one one not not 17. S ecuritization of ccounts eceivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in U.S. dollars, euros and British pounds. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14. S tock ased ompensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 23. U E The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

Cost of Goods and Service [Policy Text Block]	C ost of oods old We classify the costs of manufacturing and distributing our products as cost of goods sold. Manufacturing costs include variable costs, primarily raw materials and energy, and fixed expenses directly associated with production. Manufacturing costs also include, among other things, plant site operating costs and overhead (including depreciation), production planning and logistics costs, repair and maintenance costs, plant site purchasing costs, and engineering and technical support costs. Distribution, freight and warehousing costs are also included in cost of goods sold.
Derivatives, Policy [Policy Text Block]	D erivatives and edging ctivities All derivatives, whether designated in hedging relationships or not, three not not
Environmental Cost, Expense Policy [Policy Text Block]	E nvironmental xpenditures Environmental related restoration and remediation costs are recorded as liabilities when site restoration and environmental remediation and clean-up obligations are either known or considered probable and the related costs can be reasonably estimated. Other environmental expenditures that are principally maintenance or preventative in nature are recorded when expended and incurred and are expensed or capitalized as appropriate. See “Note 21.
Equity Method Investments [Policy Text Block]	E quity ethod nvestments We account for our equity investments where we own a non-controlling interest, but exercise significant influence, under the equity method of accounting. Under the equity method of accounting, our original cost of the investment is adjusted for our share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	F oreign urrency ranslation The accounts of our operating subsidiaries outside of the U.S., unless they are operating in highly inflationary economic environments, consider the functional currency to be the currency of the economic environment in which they operate. Accordingly, assets and liabilities are translated at rates prevailing at the balance sheet date. Revenues, expenses, gains and losses are translated at a weighted average rate for the period. Cumulative translation adjustments are recorded to equity as a component of accumulated other comprehensive loss. If a subsidiary operates in an economic environment that is considered to be highly inflationary (100% cumulative inflation over a three Foreign currency transaction gains and losses are recorded in other operating expense (income), net in our consolidated statements of operations and were a loss of $3 million, a loss of $13 million and a gain of $18 million for the years ended December 31, 2024, 2023 2022
Income Tax, Policy [Policy Text Block]	I ncome axes We use the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial and tax reporting purposes. We evaluate deferred tax assets to determine whether it is more likely than not Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The application of income tax law is inherently complex. We are required to determine if an income tax position meets the criteria of more likely than not not, 19.
Goodwill and Intangible Assets, Policy [Policy Text Block]	I ntangible ssets and oodwill Intangible assets are stated at cost (fair value at the time of acquisition) and are amortized using the straight-line method over the estimated useful lives or the life of the related agreement as follows: In years Patents and technology 5 - 30 Trademarks 9 - 30 Licenses and other agreements 5 - 15 Other intangibles 5 - 20 In the annual period in which finite-lived intangible assets become fully amortized, we remove both the gross carrying amounts and the related accumulated amortization of these intangible assets. See “Note 10. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not third not During 2024 2023
Inventory, Policy [Policy Text Block]	I nventories Inventories are stated at the lower of cost or market, with cost determined using average cost, LIFO and first first
Lessee, Leases [Policy Text Block]	L eases The determination of whether a contract is or contains a lease is performed at the lease inception date. Lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term, using incremental borrowing rates as the implicit rates are not 9.
Legal Costs, Policy [Policy Text Block]	L egal osts We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred.
Earnings Per Share, Policy [Policy Text Block]	N et ncome er hare ttributable to untsman orporation Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as potential dilutive securities. Diluted income per share is computed using the treasury stock method for all stock-based awards. In periods with reported loss from continuing operations attributable to Huntsman Corporation, all stock-based awards are generally deemed anti-dilutive and would be excluded from the calculation of diluted income per share from continuing operations, discontinued operations and net income regardless of whether there is income or loss from discontinued operations and net income. Basic and diluted (loss) income per share were determined using the following information (in millions): Year ended December 31, 2024 2023 2022 Numerator: (Loss) income from continuing operations attributable to Huntsman Corporation $ (162 ) $ (17 ) $ 448 Net (loss) income attributable to Huntsman Corporation $ (189 ) $ 101 $ 460 Denominator: Weighted average shares outstanding 172.1 177.4 201.0 Dilutive shares: Stock-based awards — — 2.0 Total weighted average shares outstanding, including dilutive shares 172.1 177.4 203.0 Additional stock-based awards of 2.1 million, 3.1 million and 1.1 million weighted average equivalent shares of stock were outstanding during the years ended December 31, 2024, 2023 2022 not December 31, 2024 2023
Other Noncurrent Assets [Policy Text Block]	O ther oncurrent ssets Periodic maintenance and repairs applicable to major units of manufacturing facilities (a “turnaround”) are accounted for on the deferral basis by capitalizing the costs of the turnaround and amortizing the costs over the estimated period until the next turnaround.
Consolidation, Policy [Policy Text Block]	P rinciples of onsolidation Our consolidated financial statements include the accounts of our wholly-owned and majority-owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated.
Property, Plant and Equipment, Policy [Policy Text Block]	P roperty, lant and quipment Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives or lease term as follows: In years Buildings 10 - 40 Plant and equipment 3 - 30 Furniture, fixtures and leasehold improvements 5 - 20 Interest expense capitalized as part of plant and equipment was $7 million, $6 million and $7 million for the years ended December 31, 2024, 2023 2022 Normal maintenance and repairs of plant and equipment are charged to expense as incurred. Renewals, betterments and major repairs that materially extend the useful life of the assets are capitalized, and the assets replaced, if any, are retired.
Revenue from Contract with Customer [Policy Text Block]	R evenue ecognition We generate substantially all of our revenue through product sales in the open market and long-term supply agreements in which revenue is recognized at a point in time. At contract inception, we assess the goods and services, if any, promised in our contracts and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In substantially all cases, a contract has a single performance obligation to deliver a promised good to the customer. Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Revenue is measured as the amount that reflects the consideration that we expect to be entitled to in exchange for those goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. We have elected to account for all shipping and handling activities as fulfillment costs. We have also elected to expense commissions when incurred as the amortization period of the commission asset that we would have otherwise recognized is less than one The amount of consideration we receive and revenue we recognize is based upon the terms stated in the sales contract, which may not one one not not 17.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block]	S ecuritization of ccounts eceivable Under our A/R Programs, we grant an undivided interest in certain of our trade receivables to the special purpose entities in the U.S. and EU. This undivided interest serves as security for the issuance of debt. The A/R Programs provide for financing in U.S. dollars, euros and British pounds. The amounts outstanding under our A/R Programs are accounted for as secured borrowings. See “Note 14.
Share-Based Payment Arrangement [Policy Text Block]	S tock ased ompensation We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost, net of estimated forfeitures, will be recognized over the period during which the employee is required to provide services in exchange for the award. See “Note 23.
Use of Estimates, Policy [Policy Text Block]	U E The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

[1]Geographic information for revenues is based upon countries into which product is sold.[2]Adjusted fixed costs include fixed costs, less depreciation and amortization.[3]Other segment items include other operating and non-operating income and expense items and foreign currency exchange effects.[4]We use segment adjusted EBITDA as the measure of each segment’s profit or loss. We believe that segment adjusted EBITDA more accurately reflects what our CODM uses to make decisions about resources to be allocated to the segments and assess their financial performance. Our CODM is the senior executive committee that includes our Chief Executive Officer and our Chief Financial Officer. Segment adjusted EBITDA is defined as net income of Huntsman Corporation or Huntsman International, as appropriate, before interest, income tax, depreciation and amortization, net income attributable to noncontrolling interests and certain Corporate and other items, as well as eliminating the following adjustments: (a) business acquisition and integration expenses and purchase accounting inventory adjustments, net; (b) fair value adjustments to Venator investment, net and other tax matter adjustments; (c) certain legal and other settlements and related expenses; (d) loss on sale of business/assets; (e) loss on dissolution of subsidiaries; (f) amortization of pension and postretirement actuarial losses; (g) restructuring, impairment, plant closing and transition costs; (h) (loss) income from discontinued operations, net of tax; (i) certain nonrecurring information technology project implementation costs; (j) costs associated with the Albemarle Settlement, net; (k) income from transition services arrangements; and (l) plant incident remediation credits.[5]Corporate and other costs, net includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, nonoperating income and expense and gains and losses on the disposition of corporate assets.[6]Certain legal and other settlements and related expenses for the year ended December 31, 2024 includes approximately $10 million related to the settlement of a claim in connection with a commercial dispute.[7]Loss on dissolution of subsidiaries for the year ended December 31, 2024 relates to the elimination and non-cash recognition of cumulative translation adjustments from accumulated other comprehensive loss due to the liquidation of certain subsidiaries.[8]Includes costs associated with transition activities relating primarily to our Corporate program to optimize our global approach to managed services in various information technology functions and our program to realign our cost structure in Europe.[9]Variable direct costs primarily include raw materials, utilities and freight-related costs.[10]A reconciliation of total reportable segments’ revenues to total consolidated revenues is provided in “Note 17. Revenue Recognition.”
