Notice: Canadian Counter-Tariffs

As of September 16, 2026
Certain U.S.-origin goods supplied by TCH are affected

Canada’s counter tariff effective date September 8, 2026

TCH billing September 28, 2026

The Government of Canada has expanded counter-tariff measures on certain U.S.-origin goods, including selected steel derivatives and fasteners. TCH is providing this advance notice, so customers have time to prepare. After TCH implements the billing change, costs for affected products will increase.

How customers may be affected

• After TCH implements the charge, affected items will carry a higher cost.

• The impact depends on the product’s HS classification and country of origin.

• The tariff will not apply to every TCH product, only products from the complete list.

TCH sales approach

TCH has previously absorbed certain tariff costs, including the 25% Canadian tariff on specified steel derivative products, which has been in effect since December 26, 2025. Due to the higher rates and wider product coverage, TCH will begin passing applicable surtax costs through on affected products.

Due to the higher rates and wider product coverage, TCH will begin passing applicable surtax costs through on affected U.S.-origin products.

Important: Final surtax treatment depends on the applicable government measure, the product’s HS classification, and its country of origin. The U.S. surtaxes apply only to qualifying U.S.-origin goods.

HS Codes for TCH Products Affected by Tariffs

This working list is not exhaustive. Final treatment depends on product classification and country of origin. The surtaxes do not stack. When a U.S. surtax applies to a product, the steel derivative surtax does not apply on top of it.
