BIS clarifies U.S. content for Section 232 mobile equipment tariffs
The guidance sets a new methodology for determining U.S. content in mobile industrial equipment that qualifies under the US‑MCA, potentially shifting the tariff burden for firms importing or exporting such goods.
The U.S. Bureau of Industry and Security released guidance on Oct 14 2026 that revises how to calculate the “U.S. content” of mobile industrial equipment and machinery subject to Section 232 metal tariffs and falling within the USMCA qualifying list. The new methodology includes specific break‑downs of component percentages, recent shipment data, and updated weight‑based formulas. Firms engaged in importing or exporting mobile equipment will need to reassess their tariff calculations, as the guidance may lower the audit threshold for certain items and alter duty amounts. Compliance teams should review the new weightings and update internal procurement reports accordingly. The guidance has yet to be tested in real‑world customs cases, so stakeholders should monitor enforcement actions for further clarification as regulators adapt and anticipate.
