Urgent Customs Advisory: Import Prohibitions on Certain Canadian Dairy, Vehicles, and Alcohol

U.S. Customs and Border Protection (CBP) has issued CSMS Message #70050970 following Presidential Proclamations 11061, 11062, and 11063, announcing sweeping import exclusions on specific Canadian goods in response to ongoing trade disputes concerning dairy, motor vehicles, and alcoholic beverages.

Effective September 29, 2026, at 12:01 a.m. Eastern Time, covered products of Canadian origin are entirely excluded from importation into the United States. This restriction completely precludes affected goods from admission into Foreign Trade Zones (FTZs) or bonded warehouses, in-bond transportation, and entry for consumption. To enforce these measures, CBP has updated the Automated Commercial Environment (ACE) to automatically reject non-compliant entries and cancel unreleased submissions, generating system error codes such as 239, 335, and 886.

The restrictions target specific Harmonized Tariff Schedule (HTS) headings, most notably covering select dairy and agricultural inputs under headings 0404, 1702, and 1703, motor vehicles under heading 8711, and a wide array of alcoholic beverages spanning headings 2202 through 2208. For alcohol, the outright ban applies strictly to direct-to-consumption packaged goods like bottles, cans, and kegs. Alcoholic beverages that do not meet this specific packaging scope are not subject to outright exclusion, remaining instead subject to the previously established 50 percent ad valorem duties under Proclamation 11046.

Goods that arrived and were imported prior to the September 29 deadline remain eligible for entry for consumption. Furthermore, covered products already admitted into a bonded warehouse or Foreign Trade Zone prior to the deadline may still be withdrawn for consumption, though they will remain subject to the 50 percent ad valorem duty outlined in Proclamations 11046, 11047, and 11048.

Importers with supply chains touching Canada must act swiftly to review their HTS classifications against the presidential annexes. Continuing to ship restricted items will result in immediate cargo rejections and significant logistical delays at the border. Please reach out to our customs law firm if your supply chain requires a compliance review regarding these sudden trade enforcement updates.
