Updates to this article
  • Added a link to the subsequent September tariff-list changes and selected-product import bans. The original August publication date is unchanged.

Recorded editorial changes. Automatic timing labels do not change the publication or review dates.
Updated 9 September 2026. The August tariff remains in force. Separate changes to the tariff lists start on 15 September, followed by import bans on selected Canadian-origin products on 29 September. Read the new product-scope and deadline warning before shipping affected goods.

What has happened?

The United States has begun applying an additional 50% tariff to selected Canadian-origin goods after trade talks between the two countries ended without an agreement.

The new duties took effect at 12:01 a.m. Eastern Time on 22 August 2026. The original start date of 19 August had been postponed for three days to allow further negotiations.

Which goods are affected?

The measures cover around US$20 billion—approximately C$28 billion—of Canadian goods, representing just over 5% of Canada’s annual exports to the US.

This is not a blanket tariff on everything imported from Canada. It applies only to products covered by specific US tariff codes. The original August list includes selected products across categories such as clothing, furniture, dairy, wine, cement and sporting equipment.

The 50% is an additional tariff

The 50% charge is added to other duties that may already apply. For example, a product with an existing 5% duty could potentially face a total tariff of 55%.

What this means for UK businesses

The change does not introduce a new 50% tariff on UK-origin goods sent to the US. A UK seller could still be affected if it supplies Canadian-origin products into the American market.

Businesses should establish the customs origin and correct US tariff classification of each product rather than relying on its country of dispatch.

Canada’s separate counter-tariffs on selected US-origin goods took effect on 8 September 2026. Read the Canadian counter-tariff update; that measure concerns the opposite direction of trade.
