Segment Reporting [Abstract] |
Business Segments | Note 19. Business Segments 3M’s businesses are organized, managed and internally grouped into segments based on differences in markets, products, technologies and services. 3M manages its continuing operations in three business segments: Safety and Industrial; Transportation and Electronics; and Consumer. 3M’s three business segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. On April 1, 2024, 3M completed the previously announced separation of its Health Care business as a separate public company, Solventum (see Note 2 for additional information). 3M is an integrated enterprise characterized by substantial intersegment cooperation, cost allocations and inventory transfers. Therefore, management does not represent that these segments, if operated independently, would report the operating income information shown. 3M discloses business segment operating income as its measure of segment profit, reconciled to both total 3M operating income and income before taxes. Business segment operating income excludes certain expenses and income that are not allocated to business segments (as described below in “Corporate and Other”). Business segment disclosures consider information used by/provided to 3M's chief operating decision maker (CODM). For 3M, the CODM is the chief executive officer. The CODM uses business segment operating income to allocate resources to segments in the planning and forecasting process along with periodic ongoing reviews of results and overall market activity.

Beginning in the first quarter of 2025, "business segment assets" represent inventories, based on the extent of business segment information regularly provided to 3M's CODM. This impact is reflected in the table above for all periods presented. Business segment depreciation reflected above is based on the underlying usage of assets and allocated depreciation. Corporate and Other: Outside of 3M's reportable operating segments, 3M has Corporate and Other which is not a reportable business segment as it does not meet the segment reporting criteria. Because Corporate and Other includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis. Corporate and Other operating income (loss) includes: •Corporate special items includes, for the periods presented: ◦net costs for significant litigation impacting operating income (loss) associated with PFAS-related other environmental and Combat Arms Earplugs matters. ◦loss on business divestitures (see Note 4). ◦divestiture costs (related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture) that were not eligible to be part of discontinued operations. •Other corporate (expense) income-net includes: ◦certain enterprise and governance activities resulting in unallocated corporate costs and other activity or costs that 3M may choose not to allocate directly to its business segments. ◦commercial activity with Solventum following its April 1, 2024 Separation and certain operations of the former Health Care business segment retained by 3M. ◦transition arrangement agreements (e.g. fees charged by 3M, net of underlying costs) related to divested businesses, including those related to the Solventum Separation. ◦operations of businesses of the former Health Care segment divested prior to the Separation and therefore not reflected as discontinued operations within 3M's financial statements, along with limited-duration supply agreements with previous divestitures. ◦costs previously allocated to Solventum prior to the Separation that were not eligible to be part of discontinued operations.
