The United States and Mexico maintain a vital economic relationship, characterized by significant trade volumes. In 2025, the U.S. received goods totaling approximately $534.87 billion from Mexico, accounting for about 12.3% of its total imports by dollar value. This volume established Mexico as the primary import partner for the U.S., surpassing both Canada and China. This strong trade dynamic is largely influenced by the United States-Mexico-Canada Agreement (USMCA).

The USMCA, which superseded NAFTA in 2020, plays a crucial role in integrating the economies of the U.S., Mexico, and Canada. This updated trade agreement introduces new provisions covering digital commerce, labor protections, and environmental standards. Notably, for vehicles to qualify for tariff-free treatment, 75% of their components must be manufactured in North America, and 40% to 45% of a vehicle's value must originate from North American workers earning at least $16 per hour. These stipulations aim to promote higher-wage production and bolster the regional manufacturing sector. This framework not only offers stability for businesses and cost savings for consumers but also enhances wages and labor rights for Mexican workers.

Mexico's role as a key supplier to the U.S. involves a diverse range of products. Vehicles and automotive parts constitute the largest import categories, with major U.S. car manufacturers like Ford and GM operating production facilities in Mexico to produce cars, engines, and other components for export to the U.S. Additionally, Mexico is a significant exporter of computers to the U.S. The top five import categories from Mexico in 2024 included cars ($49.6 billion), computers ($46.6 billion), motor vehicle parts and accessories ($36.7 billion), delivery trucks ($32.0 billion), and insulated wire ($16.5 billion). Beyond these, crude petroleum, medical equipment, telephones, tractors, and video displays also represent substantial imports. The U.S. simultaneously maintains a robust export market to Mexico, with goods valued at $337.96 billion in 2025. Key exports to Mexico include refined petroleum ($29.3 billion), motor vehicle parts and accessories ($19.4 billion), integrated circuits ($8.52 billion), petroleum gas ($6.85 billion), and combustion engines ($4.77 billion).

The shift in trade dynamics, particularly Mexico surpassing China as the leading import partner for the U.S. in 2023, underscores the profound impact of trade policies and geopolitical factors. The tariff disputes initiated by the previous U.S. administration prompted many companies to relocate production facilities closer to home, with Mexico emerging as a preferred alternative due to its geographic proximity, lower labor costs, and favorable trade agreements. This strategic realignment has made Mexico an indispensable component of the U.S. supply chain, fostering a mutually beneficial economic relationship that continues to strengthen.
