Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In these notes, the terms "DuPont" or "Company" used herein mean DuPont de Nemours, Inc. and its consolidated subsidiaries. The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the interim statements reflect all adjustments (including normal recurring accruals) which are considered necessary for the fair statement of the results for the periods presented. Results from interim periods should not be considered indicative of results for the full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 ("2025 Annual Report"). The interim Consolidated Financial Statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Effective in the fourth quarter of 2025 following the separation of its semiconductor and interconnect solutions businesses (the "Electronics Business" and the separation of the Electronics Business, the "Electronics Separation"), the Company realigned its management and reporting structure. This realignment resulted in a change in reportable segments which changed the manner in which the Company reports its financial results (the "Q4 2025 Segment Realignment"), creating two new reportable segments: Healthcare & Water Technologies and Diversified Industrials. As a result, the interim Consolidated Financial Statements have been recast for all periods presented to reflect the new two segment reporting structure as described below: •Healthcare & Water Technologies includes high-performance packaging, parts and components for medical device and biopharma markets as well as water filtration and purification technologies primarily for industrial wastewater & energy, municipal drinking water & desalination, and life sciences & specialty markets. •Diversified Industrials includes building technologies, with a broad portfolio serving new-build and repair/remodel applications across non-residential and residential construction markets, and industrial technologies, which includes a portfolio of adhesive, wear and friction, and packaging solutions serving aerospace, automotive and printing and packaging markets.
Accounting Guidance Issued But Not Adopted	Accounting Guidance Issued But Not Adopted at March 31, 2026 In November 2024, the Financial Accounting Standard Board (the "FASB") issued Accounting Standards Update No. 2024-03, "Income Statement: Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures" ("ASU 2024-03") to improve disclosures about the nature of expenses within line items on the statements of operations. The amendments in ASU 2024-03 are effective for the Company's 2027 annual report and subsequent interim periods; however, early adoption is permitted. The amendments can be applied prospectively or retrospectively to all periods presented. The Company is currently evaluating the impact of adopting this guidance. In September 2025, the FASB issued Accounting Standards Update No. 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”) to modernize the accounting for internal-use software costs and improve operability of the guidance across different software development project stages. The amendments in ASU 2025-06 are effective for the Company’s 2028 annual and quarterly reports; however, early adoption is permitted. The amendments can be applied prospectively, retrospectively, or using a modified transition approach. The Company is currently evaluating the impact of adopting this guidance. In September 2025, the FASB issued Accounting Standards Update No. 2025-07, “Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivative Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract” (“ASU 2025-07”) to establish accounting requirements for contracts that meet the characteristics-based definition of a derivative and are not otherwise excluded from the Topic's scope. The amendments in ASU 2025-07 are effective for the Company’s 2027 annual and quarterly reports; however, early adoption is permitted. The amendments can be applied prospectively or on a modified retrospective basis. The Company is currently evaluating the impact of adopting this guidance.
