U.S. Sets 50% Section 338 Tariffs on 554 Canadian Tariff Lines Starting August 19
The United States will impose additional 50% ad valorem tariffs on selected Canadian imports beginning August 19, 2026, covering an estimated $20 billion in trade across 554 tariff lines including wine, cement, and hockey sticks. USMCA-originating goods are not exempt, though energy, potash, and products already under Section 232 tariffs are excluded, meaning the effective duty rate will vary by product. Canada's Trade Minister Dominic LeBlanc is traveling to Washington this week for negotiations, but no retaliatory measures or changes to the August 19 schedule have been announced.
