Pursuant to a Presidential Proclamation issued October 23, 2026, the scope of products of Canada subject to the 50% Section 338 tariffs has again been modified. Certain HTS numbers have been removed from the list of subject products and new HTS numbers have been added. These modifications are effective October 30, 2026 at 12:01 EST. Any subject product crossing the border on or after this date and time will incur these 50% tariffs.
The list of HTS numbers added and removed can be found HERE. Note the product descriptions are provided for informational purposes only. Section 338 applicability is based solely on the HTS classification number.
Subject products qualifying for USMCA preferential treatment ARE NOT exempt from Section 338 tariffs. USMCA qualification is irrelevant as it pertains to Section 338 tariffs.
