The rules-of-origin requirement under the United States-Mexico-Canada Agreement that determines whether vehicles and auto parts qualify for tariff-free trade across North America.
The United States-Mexico-Canada Agreement (USMCA) entered into force on 1 July 2020, replacing the North American Free Trade Agreement (NAFTA). The Regional Value Content (RVC) test, set out in USMCA Chapter 4 and the automotive Annex 4-B, specifies the percentage of a vehicle's or part's value that must originate in the territory of the three parties for the product to qualify for preferential, tariff-free treatment. RVC is calculated by either the net cost method or the transaction value method, with the net cost method required for most automotive applications.
Passenger vehicles and light trucks must meet a 75% RVC threshold, phased from 66% at entry into force in 2020 to 75% in 2023. Heavy trucks must meet a 70% threshold. Core, principal, and complementary parts categories have separate RVC thresholds defined in Annex 4-B. In addition to RVC, two further requirements apply to vehicles. The Labor Value Content (LVC) requirement provides that 40% to 45% of a vehicle's content (depending on segment) must be produced by workers earning at least USD 16 per hour. The steel and aluminium requirement provides that 70% of a vehicle producer's purchases of steel and aluminium must be of North American origin. Both requirements operate alongside the RVC threshold and must be met independently.
Suppliers shipping components into US OEM assembly plants are typically required to provide a USMCA certification of origin documenting the originating status of the part, supporting the OEM's vehicle-level claim. Certifications are subject to verification by US Customs and Border Protection (CBP) under USMCA Chapter 5. Failure to satisfy origin requirements eliminates preferential treatment and exposes the importer to applicable Most-Favored-Nation (MFN) tariffs. The agreement is subject to a joint review beginning in 2026, six years after entry into force, with a default sunset of 2036 absent renewal.
For European Tier 1 and Tier 2 automotive suppliers building US footprint to serve Detroit Three programmes, USMCA origin determination directly affects the cost-of-entry comparison between local US production, Mexican production, and continued European export. The corridor mechanics are detailed in the German automotive suppliers into US OEM Tier 1 pillar.
The interaction between USMCA origin rules and IRA Section 30D battery and critical-minerals requirements creates a layered compliance map for EV-related components, which the OEM customer reads as a single qualification filter at the time of supplier selection.
