Restructuring and Related Activities Disclosure [Text Block]	RESTRUCTURING AND ASSET RELATED CHARGES - NET Charges for restructuring programs and other asset related charges, which include asset impairments, are recorded in "Restructuring and asset related charges - net" in the consolidated statements of income. For additional information on the Company's restructuring programs, see Note 5 to the Consolidated Financial Statements included in the 2024 10-K. 2025 Restructuring Program On January 27, 2025, the Dow Inc. Board of Directors ("Board") approved targeted actions to further achieve the Company's cost reduction initiatives in response to ongoing macroeconomic uncertainty, while reinforcing its long-term competitiveness across the economic cycle. The actions include a workforce reduction of approximately 1,500 roles. As a result of these actions, in the first quarter of 2025 the Company recorded pretax charges of $207 million for severance and related benefits costs, included in "Restructuring and asset related charges - net" in the consolidated statements of income, related to Corporate. Costs to implement the targeted actions are expected to result in additional cash expenditures of approximately $10 million. These actions are expected to be substantially complete by the end of 2026. At March 31, 2025, $167 million of the restructuring reserve balance was included in "Accrued and other current liabilities" and $40 million was included in "Other noncurrent obligations" in the consolidated balance sheets. 2023 Restructuring Program Actions related to the restructuring program approved by the Board on January 25, 2023, were substantially complete at the end of the first quarter of 2025, with the exception of certain cash payments that will continue primarily through the second quarter of 2025. In the first quarter of 2025, the Company recorded an additional pretax restructuring charge of $5 million for asset write-downs and write-offs and an asset related credit adjustment of $4 million, included in "Restructuring and asset related charges - net" in the consolidated statements of income, related to Industrial Intermediates & Infrastructure. See Note 17 for additional information on nonrecurring fair value measurements. Restructuring implementation and efficiency costs totaled $50 million for the three months ended March 31, 2025 ($46 million for the three months ended March 31, 2024). Subsequent Event On April 24, 2025, the Company announced actions to further address the impact on the Company from ongoing macroeconomic volatility and slower GDP growth. The actions include the expansion of the previously announced strategic review of select European assets, which is focused on addressing the persistently challenging demand dynamics and regulatory environment in the geographic region. The Company expects to complete the review of its European assets and announce final actions by mid-2025, and has initially identified three assets it believes will require further action. The assets identified represent higher-cost, energy intensive upstream portions of the Company’s portfolio, and include an ethylene facility in Böhlen, Germany (Packaging & Specialty Plastics), chlor-alkali and vinyl assets in Schkopau, Germany (Industrial Intermediates & Infrastructure), and a basics siloxanes plant in Barry, United Kingdom (Performance Materials & Coatings). The assets will be evaluated for potential idle or shut down. The assets have a total net book value of approximately $275 million and the Company will assess the potential impact of the actions on the assets’ carrying values as the review progresses.
