U.S. expands tariff retaliation against Canada as talks stall

The new 50% tariffs apply to additional Canadian products starting September 15, with Section 338 measures still covering only about 5% of U.S. imports from Canada.

Action Forex said the latest U.S. response to Canada’s retaliatory tariffs comes after bilateral trade negotiations broke down, and it frames the move as a relatively minor step in the broader trade dispute.

The outlet noted that the measures include changes to the list of Canadian products subject to 50% import tariffs, effective September 15.

It said Section 338 tariffs continue to affect a small share of trade, estimated at 5% of U.S. imports from Canada, and while targeted sectors face significant disruption, the broader economic impact appears limited so far.

Action Forex added that the main risk remains future escalation into a wider tit-for-tat tariff fight that covers a much larger share of trade, which it said has not occurred with the latest development yet.
