Mexico recorded a sharp decline in vehicle exports in September 2026 as United States tariffs continued to affect the country's automotive industry. According to Mexico's National Institute of Statistics and Geography (INEGI), vehicle exports fell by 11.85% compared with September 2025, reaching 277,369 units. The decline was the largest recorded since December 2025, while domestic vehicle production dropped by 15.13% to 301,803 units.

The decline comes as Mexico and the United States continue discussions over their trade agreement. Mexican-made vehicles remain subject to US tariffs of up to 25%, although Mexican officials estimate that compliance with North American content requirements can reduce the effective tariff burden to around 10% to 12%. Industry analysts said the tariffs and uncertainty surrounding US trade policies have affected manufacturing and export decisions.

The Mexican Automotive Industry Association (AMIA) reported that Mexico remains the largest foreign supplier of vehicles to the United States, accounting for approximately 16% of light vehicles in the US market. However, Mexican vehicle exports to the United States declined by 5% during the first nine months of 2026, while shipments to Canada increased by more than 9% over the same period.

The slowdown could also affect maritime trade, particularly vehicle carriers transporting automobiles between Mexico and international markets. Lower export volumes may reduce demand for automotive shipping services if the decline continues. Industry analysts warned that prolonged trade uncertainty could influence future manufacturing investments, vehicle production, and international transportation activity.
