Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation The accompanying Unaudited Interim Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all material adjustments which are of a normal and recurring nature necessary for a fair statement of the results for the periods presented have been reflected. Amounts are reported in millions of dollars, except per share amounts, unless otherwise noted. For further information, refer to the consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2024. The terms "Corporation," "Company," "Kimberly-Clark," "K-C," "we," "our" and "us" refer to Kimberly-Clark Corporation and its consolidated subsidiaries. International Family Care and Professional ("IFP") Transaction On June 5, 2025, we announced that the Company will form a joint venture with Suzano S.A. ("Suzano") and Suzano International Holding B.V., a wholly-owned subsidiary of Suzano ("Buyer"), comprised of substantially all the operations of the Company's former International Family Care and Professional ("IFP") segment (the "IFP Business"). To facilitate this transaction, we entered into an Equity and Asset Purchase Agreement (the "Purchase Agreement") with Buyer, pursuant to which we will, among other things, effectuate a reorganization through the transfer of certain assets, liabilities and equity interests of the IFP Business to Kimberly-Clark IFP NewCo B.V., an indirect wholly-owned subsidiary of the Company (the "Joint Venture"). At the time of closing, which is expected to take place in mid-2026 and will only take place following the satisfaction of consultation requirements and customary closing conditions, including obtaining required regulatory approvals, Buyer will acquire a 51% interest in the Joint Venture for a purchase price of approximately $1.7 billion, subject to certain closing adjustments set forth in the Purchase Agreement, and we will retain a 49% equity interest (the "IFP Transaction"). In accordance with ASC 205, Presentation of Financial Statements, we determined the IFP Transaction represents a strategic shift that will have a major effect on our operations and financial results. Accordingly, the results of the IFP Business are reported as discontinued operations in the accompanying Condensed Consolidated Statements of Income and have been excluded from both continuing operations and segment results for all periods presented. Further, the assets and liabilities of the IFP Business are classified as discontinued operations in the accompanying Condensed Consolidated Balance Sheets for all periods presented, and the Company has ceased depreciating and amortizing the long-lived assets of the IFP Business. The Condensed Consolidated Statements of Comprehensive Income, Stockholders' Equity and Cash Flows are presented on a consolidated basis for both continuing operations and discontinued operations. Unless otherwise noted, amounts and disclosures in the Notes to the Unaudited Interim Condensed Consolidated Financial Statements reflect only Kimberly-Clark's continuing operations. See Note 3 for additional details. Highly Inflationary Accounting GAAP requires the use of highly inflationary accounting for countries whose cumulative three-year inflation exceeds 100%. Under highly inflationary accounting, the countries’ functional currency becomes the U.S. dollar, and its income statement and balance sheet are measured in U.S. dollars using both current and historical rates of exchange. As of July 1, 2018, we adopted highly inflationary accounting for our subsidiaries in Argentina (“K-C Argentina”). The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in Other (income) and expense, net. As of September 30, 2025, K-C Argentina had an immaterial net peso monetary position. Net sales of K-C Argentina were approximately 1% of our consolidated net sales for the three and nine months ended September 30, 2025 and 2024. As of April 1, 2022, we adopted highly inflationary accounting for our subsidiary in Türkiye (“K-C Türkiye”). The effect of changes in exchange rates on lira-denominated monetary assets and liabilities has been reflected in earnings in Other (income) and expense, net. As of September 30, 2025, K-C Türkiye had an immaterial net lira monetary position. Net sales of K-C Türkiye were less than 1% of our consolidated net sales for the three and nine months ended September 30, 2025 and 2024. Recently Issued Accounting Standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). The new guidance is intended to enhance the transparency and decision usefulness of annual income tax disclosures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied on a prospective basis with retrospective application permitted. As the guidance requires only additional disclosure, there will be no effects of this standard on our financial position, results of operations or cash flows. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220). The new guidance requires disclosure in the notes to the financial statements of disaggregated information about specific expense categories underlying certain income statement expense line items. The amendments in this ASU are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments should be applied on a prospective basis with retrospective application permitted. We are currently evaluating the impact of this update on our consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350) to modernize the accounting guidance for internal-use software costs. The new guidance eliminates software development stages and clarifies when to begin capitalizing eligible software costs. The amendments in this ASU are effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. The amendments can be applied on a prospective basis, a modified basis for in-process projects or a retrospective basis. We are currently evaluating the impact of this update on our Consolidated Financial Statements and related disclosures.
