Auto parts face a unique tariff landscape including Section 232 national security tariffs and USMCA content requirements. See current rates by part type and country of origin.
The auto parts tariff environment is among the most complex in US trade policy. Multiple overlapping tariff authorities create a compliance challenge for importers. A single brake assembly from China might face the 2.5% MFN rate plus a 25% Section 301 tariff plus a 34% reciprocal surcharge, for a combined rate exceeding 60%. The same part from Mexico might enter duty-free under USMCA if it meets the regional value content requirements. This wide gap in effective rates has accelerated supply chain reshoring toward North America.
USMCA transformed the automotive tariff landscape by raising regional value content requirements to 75% for qualifying vehicles and parts. Parts that meet these requirements enter duty-free between the US, Canada, and Mexico. Parts that fail to qualify face potential Section 232 tariffs. The tracing and documentation requirements are significant, but the tariff savings make compliance worthwhile for most auto parts importers with Mexican or Canadian suppliers.
Auto parts face base MFN rates of 0-6% for most categories, plus potential Section 232 tariffs (25% on certain parts not meeting USMCA requirements), Section 301 tariffs (25% for China-origin parts), and reciprocal surcharges. The total effective rate depends heavily on the specific part, its country of origin, and whether it qualifies for USMCA preferential treatment.
USMCA provides duty-free treatment for qualifying auto parts from Mexico and Canada, but the rules of origin are complex. Parts must meet regional value content requirements of 75% for most categories. Parts that do not meet USMCA requirements may face the MFN rate or Section 232 tariffs. Proper documentation of origin is essential.
Section 232 tariffs of 25% apply to certain imported auto parts that are deemed critical to national security, particularly those not meeting USMCA origin requirements. The scope of covered parts has been adjusted multiple times and currently includes engines, transmissions, electrical components, and body stampings among others.
