Canada Announces Counter Tariffs on U.S. Imports

Overview & Tariff Details  

As previously announced, on July 20, 2026, the U.S. implemented Section 338 tariffs on many Canadian imports including cosmetics, food and machinery imports. These 50% Section 338 tariffs became effective on applicable Canadian imports on or after August 22, 2026.  

On August 25, 2026, Canada announced counter (retaliatory) import tariffs, matching the U.S. Section 338 tariffs on import value. Canada’s counter tariffs represent an additional tariff of 15%, 25% or 50%, depending on the product being imported, and are effective on or after September 8, 2026. 

What Canadian Importers Should Know 

• The Canadian Department of Finance notice lists all products subject to these counter tariffs based on the assigned Canadian HS code and related description(s). 

• Counter tariffs apply to products of U.S. origin only, regardless of the country of export to Canada. 

• Products eligible for the Canada-United States-Mexico Free Trade Agreement (CUSMA) will be subject to these counter tariffs.  

• Products in transit direct to Canada prior to the effective date will not be subject to these counter tariffs. 

• Products subject to these additional tariffs are broad in scope including seafood, dairy, steel, furniture and many others. 

• Entered (declared) import values must be compliant and should be carefully reviewed to potentially mitigate the impact of applicable tariffs. 

• Further related guidance will be provided by Canada Border Services Agency (CBSA) through their website.
