Segment Reporting [Abstract]  
Business Segments
Note 16. Business Segments
3M’s businesses are organized and managed in three business segments: Safety and Industrial; Transportation and Electronics; and Consumer — based on differences in markets, products, technologies and services. These segments bring together related 3M technologies, enhance innovation and provide efficient resource sharing. As an integrated enterprise, 3M has substantial intersegment cooperation, cost allocations and inventory transfers. Accordingly, 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, which is reconciled to both total 3M operating income and income before taxes. This measure excludes certain expenses and income not allocated to business segments (as described below in “Corporate”). Business segment disclosures consider information used by/provided to 3M's CODM, who is the chief executive officer. The CODM uses business segment operating income to allocate resources in the planning and forecasting process and in reviews of results and overall market activity.
Effective in the first quarter of 2026, the measure of segment operating performance and segment composition used by the CODM changed. As a result, 3M’s disclosed measure of segment profit and other segment-related amounts were updated to align with these changes. The financial information presented herein reflects the impact of these changes for all periods presented. These include:
•Reflecting manufactured PFAS products activity and net costs for respirator mask/asbestos litigation special items within Corporate: Previously, these special items were included in the Transportation and Electronics segment and Safety and Industrial segment, respectively. Elements related to manufactured PFAS products activity are now included in Corporate, with sales and income (loss) reflected as a special item. Net costs related to respirator mask/asbestos are now also reflected in Corporate, within the net costs for significant litigation Corporate special item.

•Corporate-level (expense) income 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 2024 spin-off from 3M, as well as certain operations of 3M’s former health care business segment that were retained by 3M, and
◦transition arrangement agreements (e.g., fees charged by 3M, net of underlying costs) related to divested businesses, including those related to Solventum.
•Corporate special items include, for the periods presented:
◦net costs for significant litigation impacting operating income (loss),
