Automakers Urge USMCA Extension to Avoid Up to 10% Auto Tariffs
Automotive trade associations representing GM, Ford and Stellantis urged Congress to extend key USMCA auto content rules ahead of their 2026 expiration. They warn shifting to bilateral deals with Japan, the UK and EU could expose North American vehicle shipments to up to 10% tariffs.
1. Trade Groups Lobby for USMCA Extension
A coalition of automotive trade associations, including the Alliance for Automotive Innovation, has formally petitioned US lawmakers to extend the auto-specific rules of the United States-Mexico-Canada Agreement beyond their slated 2026 expiry. The groups argue that continuity in regional content thresholds and tariff-free access is critical to maintaining efficiency in production lines spanning the three countries.
2. Risks of Bilateral Agreements
Industry leaders caution that replacing uniform USMCA provisions with separate accords—currently under negotiation with Japan, the UK and the EU—could fragment the supply chain and subject exports to divergent tariff schedules. While USMCA guarantees zero duties on qualifying vehicles, bilateral partners like the UK may impose up to 10% import tariffs without the broader pact.
3. Implications for General Motors
General Motors, which sources engines and transmissions across North America, stands to face elevated costs and logistical complexity if USMCA auto rules are not preserved. Potential tariff barriers could increase the landed cost of GM vehicles in key export markets, pressuring profit margins and production planning.
