Fenestration Canada Update on 338 US Tariffs and Canadian response

Dear Members,

The Government of Canada announced today that it will impose a new round of counter-tariffs on U.S. goods effective September 8, 2026, in response to the U.S. Section 338 tariffs. 

Unfortunately, several tariff items directly relevant to the Canadian fenestration industry are included in the government's list.

Of particular concern are:

7610.10.00 - Aluminum doors, windows and their frames and thresholds for doors: 50%

7308.30.00 - Iron or steel doors, windows and their frames and thresholds for doors: 50%

7318 - Iron and steel fasteners: 50%, including screws, bolts, nuts, washers, rivets and other commonly used fastening products

8302.42.00 & 8302.49.00 - Base mounting and fittings for doors and windows 25%

Now that the final list has been released, we need to understand the practical impact on members as quickly as possible.

If your company imports products under these tariff classifications, or relies on U.S.-origin aluminum or steel products and components that may be captured elsewhere on the list, please reach out to us.

In particular, it would be helpful to know:

• What products or components you expect to be affected;

• Your approximate exposure to U.S.-origin supply;

• Whether equivalent Canadian or non-U.S. supply is realistically available;

• The expected impact on your costs, production or customers; and

• What response you would like Fenestration Canada to pursue with the federal government, including whether tariff relief or remission should be considered.

  
  

This information will help us determine unintended consequences for Canadian manufacturers and what action we should recommend to government.

Alongside today's tariff announcement, the Government of Canada announced a new and expanded $7.5 billion support package for Canadian businesses and workers affected by U.S. tariffs.

The Government of Canada has also expanded programs intended to help Canadian businesses respond to tariff-related disruption. Of the programs they mentioned, the BDC's Pivot to Grow program appears most promising for those looking to gap fund either improvements or remedy expected shortfalls. Funding can help manage the impact of tariffs and adapt operations, including addressing cash-flow pressures, changing supply chains, purchasing equipment or making other investments required to adjust to the new trade environment.

Here's a link to the program and we'll be reaching out to the BDC to gather more information - https://www.bdc.ca/en/financing/pivot-grow-loan

Fenestration Canada will continue monitoring available supports and will share additional programs where they are likely to be practically useful to members.

Humbly Yours,

Adrian Edge
