🚗 Automotive & Mobility
U.S.–Mexico's Most Integrated Industry
Mexico is the largest supplier of automotive parts to the United States — surpassing both Canada and China — and has been for nearly a decade. The Bajío corridor, the Hermosillo Sonoran desert, and the Tijuana-Tecate border zone form an integrated North American production system that builds everything from pickup trucks and passenger vehicles to precision wiring harnesses and high-voltage EV battery components.
The U.S. and Mexico share a deeply integrated automotive supply chain under USMCA rules of origin requiring 75% North American content for passenger vehicles. Parts cross the border multiple times during production — a typical U.S.-assembled vehicle uses components that have traveled back and forth six to eight times. This integration is a structural advantage: tariff disruptions affect both sides, creating bilateral pressure for resolution.
Labor costs, USMCA access, geographic proximity, and four decades of OEM investment make Mexico the only viable near-term alternative to Chinese or Southeast Asian sourcing for most automotive categories. The active OEM presence — GM, Mazda, Honda, Toyota, Ford — means the supplier ecosystem is dense, qualified to international standards, and continuously audited.
Las Ventajas Estructurales
Four Major OEMs, One Integrated Corridor
GM (Silao), Mazda (Salamanca), Honda (Celaya & Apaseo), Toyota (Apaseo), and Ford (Hermosillo) all operate active plants. This density creates a deep Tier 1–3 supplier network available to sourcing teams beyond the OEMs themselves.
USMCA 75% RVC — Built-In Access
Automotive parts qualifying under USMCA Chapter 8 Rules of Origin enter the U.S. at 0% tariff. Mexico's supplier base has been restructured around this threshold — most established suppliers carry documentation and compliance systems ready for audit.
Logistics Infrastructure Designed for This
Puerto Interior (Silao, GTO) connects the Bajío directly to Laredo TX via rail and highway. Laredo is the busiest inland port in the U.S. Ford Hermosillo ships to the Arizona border. The Tijuana-Tecate corridor handles commercial truck crossings 24/7.

Ver Investigación Completa →T-MEC y Panorama Arancelario Actual
USMCA-compliant auto parts currently face de facto 0% tariff. The formal USMCA review opened in 2026 — AMIA has made elimination of Section 232 tariffs on auto parts its top priority in the review process.
| Medida | Tasa | Productos | Impacto |
|---|---|---|---|
| Section 232 – Steel | 25% | Steel inputs for auto manufacturing | Increases input costs for OEMs using imported steel; partially offset by USMCA-compliant sourcing |
| Section 232 – Aluminum | 25% | Aluminum auto body parts and components | Affects light-vehicle manufacturers; USMCA-compliant finished vehicles largely shielded |
| IEEPA – Auto Parts | 25% | Non-USMCA-compliant parts and components | Qualifying suppliers largely exempt; non-qualifying face full rate — verify supplier RVC documentation |
| USMCA Auto (Compliant) | 0% | Parts meeting 75% RVC + labor value content | Full exemption — the reason Mexico's automotive supply chain is being restructured around USMCA |
