U.S. Customs and Border Protection (CBP) has issued new guidance regarding certain Canadian products that will be prohibited from importation into the United States beginning September 29, 2026.

This represents an important change from the additional Section 338 duties previously imposed on certain Canadian goods.

Effective September 29

Beginning at 12:01 a.m. Eastern Time on September 29, 2026, certain Canadian products identified in Presidential Proclamations 11061, 11062 and 11063 will be excluded from importation into the United States.

For covered products, this means they cannot be:

  • Entered for consumption
  • Transported in-bond
  • Admitted into a Foreign Trade Zone
  • Entered into a bonded warehouse

CBP will reject entries containing covered products that are subject to the prohibition.

What Products Are Affected?

The restrictions apply to specifically identified Canadian products within certain HTSUS classifications involving:

  • Alcoholic beverages
  • Dairy and related products
  • Certain motor vehicle-related products

Not every product falling within these general categories is necessarily prohibited. Applicability depends on the specific HTSUS classification and, in some cases, additional scope requirements outlined in the applicable Presidential Proclamation.

For alcoholic beverages in particular, certain packaging and other scope limitations apply.

What About Goods Already Imported?

Covered products imported before 12:01 a.m. Eastern Time on September 29 may remain eligible for entry.

Certain affected goods that were placed into a bonded warehouse or admitted into a Foreign Trade Zone before the prohibition takes effect may also be withdrawn for consumption, but will remain subject to the applicable 50% additional Section 338 duty.

Importers Should Review Upcoming Canadian Shipments

If you have affected merchandise currently moving from Canada or shipments planned for arrival on or after September 29, we recommend reviewing them as soon as possible.
