US Escalates Canada Trade Spat With Import Bans
The White House has imposed import bans on certain Canadian products, including alcohol and dairy, under Section 338 of the Tariff Act of 1930 in a significant escalation of the ongoing trade dispute.
In a significant escalation of a bilateral trade dispute, the White House has invoked Section 338 of the Tariff Act of 1930 to impose import bans on a range of Canadian goods. The presidential proclamations, issued September 8, 2026, were a direct response to Canadian retaliatory tariffs and are set to take effect on September 29. The banned products include certain alcoholic beverages, dairy products, molasses, and motorcycle products. These measures compound existing 50% tariffs on other Canadian goods that took effect in August.
The U.S. and Canadian markets are deeply integrated, and these bans threaten to severely disrupt established cross-border supply chains. Sophisticated counsel should advise clients on the immediate need to review sourcing and contracts to mitigate risk. There is considerable uncertainty regarding the scope and vigor of enforcement by U.S. Customs and Border Protection, which has the authority to seize and forfeit goods imported in violation of the ban. The situation remains fluid, pending further trade negotiations that could lead to either de-escalation or additional retaliatory actions.
