The Mexican government has requested changes to the tariff system during USMCA renegotiations to address higher costs for its automotive exports [1].

This move highlights a growing trade friction between North American partners, as Mexico seeks to maintain its competitive edge against Asian manufacturers in the U.S. market.

Mexico argues that its vehicles are subject to an average effective tariff rate of 18.75% [1]. This figure is higher than the 15% tariff rate applied to vehicles imported from South Korea and Japan [1]. The discrepancy creates a pricing disadvantage for Mexican-made cars entering the United States.

Officials said that some Mexican vehicles and specific components face maximum tariff rates as high as 25% [1]. These costs persist despite the regional trade goals of the United States-Mexico-Canada Agreement.

Under current USMCA rules, a significant portion of a vehicle's components must be produced within North America to qualify for preferential treatment. Specifically, more than 75% of vehicle parts must be sourced from the region [1]. Mexico contends that despite meeting these regional content requirements, the effective tax burden remains disproportionately high compared to non-USMCA partners.

The request for a revised tariff structure comes as the three nations navigate the complexities of the trade agreement's periodic reviews. Mexico is pushing for a more equitable system that reflects the regional integration intended by the pact, one that prevents Asian competitors from holding a pricing advantage over North American producers.

“Mexico argues that its vehicles are subject to an average effective tariff rate of 18.75%.”

This dispute underscores the tension between regional trade blocs and global supply chains. If Mexico successfully lowers its effective tariffs, it could increase the volume of Mexican exports to the U.S. while potentially squeezing the market share of South Korean and Japanese automakers who currently benefit from a lower effective tax burden.
