The United States-Mexico-Canada agreement includes a clause limiting mexican exportations of cars and autoparts to american market with the World Trade Organization (WTO) preferred rate, if the USMCA origin rule is not achieved.

The restriction would apply in the case that United States takes the decision of apply global tariffs to its cars imports arguing national seguirity concerns. This tariff could be of 25% instead of the 2.5% rate that is charging now in american customs houses.
