Mexican Car Exports Drop 12% in September Under US Tariff Pressure

Mexican car exports fell 12% in September compared to the same month last year, marking the steepest decline since December 2025, according to data from Mexico's national statistics agency INEGI. The numbers are stark. This drop comes as Ford and other major automakers face mounting pressure from US tariff policies, threatening Mexico's most vital manufacturing sector.

Production Slumps While Domestic Sales Rise

The decline wasn't limited to exports. Monthly production dropped 15%, signaling that Mexican factories are scaling back output in response to weak foreign demand. Yet the domestic market offered a silver lining, with car sales rising 8% during September, helping absorb some of the shock. The home market is moving in the opposite direction.

These figures arrive at a sensitive moment, as the United States-Mexico-Canada Agreement undergoes review. Ford and other companies still face US tariffs of up to 25%, though Mexican officials estimate that compliance with rules of origin requiring North American-made components reduces the effective burden to between 10% and 12%.

Uncertainty Hits Corporate Decisions

The economies of Mexico and the United States have been deeply intertwined for over three decades of free trade agreements. But sudden shifts in policies and tariffs during President Donald Trump's administration have created uncertainty among companies and disrupted supply chains built over years. Decisions have become harder to make.

Janet Quiroz, director of economic analysis at Monex, said the uncertainty has affected automakers' decisions on production and exports. She warned that Mexico's heavy reliance on the US market represents the sector's biggest risk. September's data represents a "warning sign, not a crisis indicator," she added, but if the trend continues through 2027, it could turn into a structural challenge for Mexico's manufacturing sector.

Tariffs aren't just a line in a budget. They're a factor reshaping the global production map. Companies like Ford may reconsider how they distribute their factories. Mexico, which built its economy on integration with the north, finds itself facing a tough test. The question isn't whether exports will recover, but when.
