President Trump signed five proclamations expanding trade measures against Canada under Section 338 of the Tariff Act of 1930. The proclamations ban imports of certain Canadian motorcycles, dairy products and alcoholic beverages effective September 29, and modify the scope of 50 percent additional tariffs on Canadian motor vehicles and alcohol from September 15. The measures respond to Canada's continued automotive tariff regulation, dairy tariff-rate quota discrimination and provincial restrictions on American alcohol.

The scope of 50 percent additional tariffs on Canadian motor vehicles and alcoholic beverages is modified effective September 15.
Canada began applying tariffs of 15, 25 or 50 percent on certain U.S. products on September 8 in response to U.S. tariffs.

Import Ban Details

Three proclamations signed by President Trump ban imports of certain Canadian motorcycles, dairy products and alcoholic beverages effective September 29. The products were previously subject to a 50 percent additional tariff. Goods imported before September 29 but not yet released for free circulation or withdrawn from warehouse for consumption continue to face the 50 percent tariff. If the ban is overturned by judicial or administrative action, the affected products automatically revert to a 50 percent additional tariff.

Tariff Scope Modification

Two additional proclamations modify the scope of 50 percent additional tariffs on Canadian motor vehicles and alcoholic beverages effective September 15. The modifications add certain Canadian products to the 50 percent tariff list and remove others, based on recommendations of senior economic officials and the public interest. The measures respond to Canada's motor vehicle and alcoholic beverage policies.

Trade Dispute Background

In July, the U.S. administration announced 50 percent tariffs on certain Canadian goods, citing discriminatory practices against American products. The tariffs were suspended for three days on August 18 under negotiation commitments, then took effect on August 22 after talks failed. Canada responded with tariffs of 15, 25 or 50 percent on certain U.S. products, which began on September 8.
