The Mexican automotive sector, the backbone of the economy and a national export platform, faces a critical period of redefinition.
The automotive industry has historically been the biggest beneficiary of free trade agreements in North America, maintaining an efficient flow of products. However, the upcoming mid-term review of the T-MEC (USMCA), scheduled for July 2026, generates great uncertainty.
Its immediate future is determined by two main challenges: the programmed T-MEC review and the constant threat of tariffs resulting from the United States' Section 232.
US Agenda and Pressure on Mexico: Rogelio Garza of AMIA (Mexican Automotive Industry Association) stated that the United States will seek an in-depth review of the Automotive Rule of Origin (ROO), demanding that regional content exceed the current 75%. Stricter oversight of labor compliance in Mexico and the updating of criteria for the purchase of steel and aluminum are also expected. A strategic point is the incorporation of specific rules for Electric/Hybrid Vehicles (EV/H).
Tariff Threat (Section 232): The application of Section 232 since 2025 has imposed a 25% duty on vehicles that do not strictly comply with the rules of origin, allowing only US-origin content to be discounted, which negatively impacts Mexican competitiveness. The industry sees the 2026 review as the crucial opportunity to obtain a definitive exemption from this punitive measure.
Mexico consolidates its exporter profile by sending between 85% and 88% of its production abroad, with about 80% directed to the United States. Despite the complex geopolitical context and commercial uncertainty, the sector demonstrated resilience in 2025 with a marginal drop in production (-0.9%) and exports (-2.7%), and positive growth in the domestic market (+1.4%).
The T-MEC review is of fundamental importance, as the automotive sector represents about 22% of the total trade regulated by the treaty; challenges and opportunities are connected to the renegotiation of the agreement, including:
Competitive Asymmetry and Risk of Production Shift: Mexico operates with the disadvantage of having to bear 25% tariffs for vehicles that do not comply with the ROOs, while partners such as Japan, South Korea, or the EU have obtained lower tariffs. The main risk is the displacement of Mexican manufacturing production if the United States increases imports from countries with preferential agreements.
Complexity of Rules of Origin: Chapter 4 and Annex 4-B of the T-MEC have proven difficult to implement, especially for SMEs. Currently, it is estimated that 60% of products comply with the rules, with an ambitious target of 80% by 2026.
Nearshoring: The phenomenon of reallocating production chains offers a historic opportunity, the materialization of which depends on success in the renegotiation, the strengthening of internal competitiveness (infrastructure, energy, security), and an effective national strategy for attracting FDI.
The Mexican strategy must focus on securing duty-free access to the US market. A solid negotiation basis could be a mechanism similar to the original agreement for the exemption of Section 232 for 2.6 million vehicles, perhaps evolving towards a negotiated tariff quota.
Stability and certainty of the T-MEC are essential conditions for unlocking substantial investments currently on hold. The 2026 review must reaffirm regional productive integration in the context of electromobility and a more protectionist global trade environment, ensuring competitiveness and legal certainty.
