On August 21, 2026, U.S. Customs and Border Protection (CBP) issued a bulletin via its Cargo Systems Messaging Service (CSMS) providing guidance on the implementation of Section 338 tariffs on certain products of Canada. 

The CSMS bulletin provides guidance on the applicable Harmonized Tariff Schedule (HTS) codes used to report the additional tariffs, as well as the applicability of the tariffs to goods admitted into a Foreign Trade Zone (FTZ). The CSMS bulletin also indicates that drawback is eligible for goods subject to the additional tariffs.

The tariffs became effective on August 22, 2026 at 12:01 am Eastern Time, and are applicable to imports from Canada of subject commodities entered for consumption, or withdrawn from warehouse for consumption, on or after that date and time.
