Intraregional agricultural trade among the United States, Canada, and Mexico has more than tripled (in inflation-adjusted value) since the implementation of the North American Free Trade Agreement (NAFTA) in 1994. In 2011-13, agricultural imports from NAFTA partners accounted for 80 percent of Mexico’s total agricultural imports, 63 percent of Canada’s imports, and nearly 40 percent of all U.S. agricultural imports.
Roughly two-thirds of U.S. agricultural imports from Mexico consist of beer, vegetables, and fruit. These imports are closely tied to Mexico's historical expertise in producing alcoholic beverages and a wide range of fruit and vegetables, along with favorable climates with growing seasons that largely complement those of the United States.
Meat, grains, vegetables, fruit, and related products make up roughly 60 percent of U.S. agricultural imports from Canada, while grains, fruit, vegetables, meat, and related products accounted for about 61 percent of U.S. agricultural exports to Canada. Grains, oilseeds, meat, and related products make up about three-fourths of U.S. agricultural exports to Mexico.
