Trump Announces 50% Tariffs on Canadian Dairy, Alcohol, Vehicles Under Section 338

President Trump announced on July 20, 2026 that his administration will impose additional 50% ad valorem tariffs on a range of Canadian products — dairy, alcoholic beverages, furniture, and motor vehicles — under Section 338 of the Tariff Act, effective 12:01 a.m. ET on August 19, 2026. The move came via three separate proclamations alleging Canadian discrimination against US commerce in those sectors. USTR estimated the tariffs affect nearly $20 billion in annual Canadian imports (reported elsewhere as up to $16 billion for the targeted categories). Analysts described the move as a warning shot to other trading partners ahead of pending Section 301 forced-labor tariff decisions.
