USMCA, Canada, & Mexico


The United States-Mexico-Canada Agreement (USMCA) is a comprehensive economic and trade agreement that modifies the free-trade area that the North American Free Trade Agreement (NAFTA) originally established in 1994. The entry-into-force date for USMCA is July 1, 2020.

NAFTA progressively eliminated almost all tariff and quota barriers governing intraregional trade among the three member countries during a 14-year transition period (1994–2008). The agreement also facilitated cross-border investment, required that sanitary and phytosanitary standards for trade be scientifically based, and expanded cooperation on environmental and labor issues.

The USMCA includes new provisions for digital trade, the protection of intellectual property, de minimis shipment levels, and financial services, among other items. In agriculture, the USMCA adds provisions on biotechnology, geographical indicators, and sanitary and phytosanitary measures. All agricultural products that had zero tariffs under NAFTA continue to have zero tariffs under USMCA, and the USMCA provides broader market opportunities for U.S. exports to Canada of dairy, poultry, and egg products.

Tables showing the USMCA countries’ share of U.S. agricultural trade for selected commodities and comparing trade-weighted ad valorem tariff rates for U.S. agricultural trade with Canada and Mexico under USMCA to Most-Favored Nation (MFN) and WTO-bound tariff rates are available on the Data page.
