Trump imposes 50% tariffs on Canadian goods under Section 338 of the Tariff Act of 1930

President Trump signed three proclamations on July 20, 2026, imposing 50% tariffs on a range of Canadian goods including wine, hockey sticks, and cement, citing discriminatory treatment of U.S. autos, alcohol, and dairy products. The tariffs invoke Section 338 of the Tariff Act of 1930, a provision never before used for this purpose, and take effect on August 19, 2026. The tariffs exclude energy, potash, fish, and critical minerals, but apply to USMCA-covered goods, a departure from previous rounds of tariffs.
