Nuevo León’s automotive export base enters the fourth T-MEC review round this week, with 67% of the light vehicles made and exported from the state going to the United States in the first half of 2026 and 6.9% going to Canada.
The immediate business issue is not a new tariff announcement. It is how rules of origin and merchandise-tracking mechanisms are defined. El Horizonte reports that Nuevo León’s export sector is watching those points closely, while Caintra Nuevo León is pressing for certainty for industry.
The September 28–29 negotiation round
Mexico and the United States are scheduled to meet in Washington on September 28 and 29. The agenda includes rules of origin, supply chains, automotive trade, steel, aluminum, economic security and reducing dependence on suppliers outside North America. The T-MEC remains in force through 2036 and more than 80% of Mexican exports to the United States retain tariff-free access under the agreement, according to El Horizonte.
Nearly $19B in Nuevo León automotive exports
Milenio reports that Nuevo León exported approximately $19 billion in automotive products in 2025, with nearly one of every three exported dollars tied to the sector. That concentration makes regional-content decisions relevant well beyond automakers: the state is also targeting vehicles and parts, electrical appliances, machinery, metal products, semiconductors and advanced manufacturing.
The Nuevo León–Texas supplier map
The state and Consejo Nuevo León are developing a Nuevo León–Texas Binational Strategy and an economic-complementarity study. The stated job is practical: identify what each region produces, which suppliers are missing and what talent the chain requires, while helping smaller companies meet origin rules and T-MEC certifications.
