On the evening of September 8, President Trump issued three proclamations barring specific Canadian imports from entering the United States under Section 338 authority. These measures escalate the trade dispute following previous rounds of 50% ad valorem duties imposed in August.
Key Details & Affected Products
The import ban targets products previously subject to the 50% duties, specifically in response to trade actions by Canada. The precise product subheadings affected by the ban are detailed in the Annexes attached to each respective proclamation.
- Excluding Certain Canadian Products from Importation into the United States in Response to Continued Discrimination Against the Commerce of the United States with Respect to Alcoholic Beverages: The U.S. cites Canada’s continued ban on the purchase, distribution, or retailing of U.S. alcoholic beverages and an additional 50% levy on U.S. alcoholic beverages effective September 8. Annex-I-Alcohol
- Excluding Certain Canadian Products from Importation into the United States in Response to Continued Discrimination Against the Commerce of the United States with Respect to Dairy: The administration points to Canada’s restrictive tariff-rate quota allocation measures, which the U.S. argues unfairly discriminate against U.S. cheeses of all types. Annex-I-Dairy
- Excluding Certain Canadian Products from Importation into the United States in Response to Continued Discrimination Against the Commerce of the United States with Respect to Motor Vehicles: The ban responds to Canada’s continued enforcement of a motor vehicle tariff scheme that places U.S. auto and auto parts exports at a competitive disadvantage. Annex-I-Motor Vehicles
Effective Date: The total import ban will take effect on September 29 at 12:01 a.m. ET.
- Goods in Transit: Any affected products that are imported but not yet entered for consumption (or withdrawn from a warehouse for consumption) prior to the September 29 deadline, will remain subject to the existing 50% ad valorem duty rate rather than the total ban.
