CBP Cargo Systems Messaging Service (CSMS) Brief

Headline

CBP implements total import exclusion for certain Canadian alcoholic beverages, dairy, and motorcycles effective September 29, 2026

Executive Summary

U.S. Customs and Border Protection issued CSMS 70050970 on September 28, 2026, providing operational guidance on Presidential Proclamations 11061, 11062, and 11063. Effective September 29, 2026 at 12:01 a.m. Eastern Time, covered Canadian products are excluded from importation entirely. The exclusion applies to Foreign Trade Zone admission, bonded warehouse entry, in-bond transportation, and consumption entry.

Bottom Line

CBP's guidance closes all U.S. customs channels to covered Canadian alcoholic beverages, dairy products, and motorcycles as of 12:01 a.m. Eastern Time on September 29, 2026. ACE systems reject non-compliant entries automatically at that moment, and any unreleased pending entries containing covered products are cancelled. Pre-exclusion inventory already in bonded warehouses or Foreign Trade Zones remains eligible for consumption withdrawal at the 50 percent ad valorem duty under the prior proclamations. Cresthaven reading: importers of record with covered Canadian goods in transit or staged in customs-controlled facilities face an immediate determination on whether those goods clear the pre-exclusion cutoff or are subject to unconditional rejection.

Key Regulatory Signals

• Total Entry Bar Begins September 29: CBP states that as of 12:01 a.m. Eastern Time on September 29, 2026, any entry containing covered products will be unconditionally rejected. The exclusion forecloses consumption entry, Foreign Trade Zone admission, bonded warehouse storage, and in-bond transportation for covered goods.
• ACE System Rejects Activate Simultaneously: CBP will update ACE Cargo Release, e214 Foreign Trade Zone admissions messaging, and ACE Entry Summary systems at 12:01 a.m. on September 29, 2026. Non-compliant submissions will trigger automated system rejects with specific error codes. Filers with pending unreleased entries containing covered products will have those entries cancelled at that moment.
• Pre-Exclusion Inventory Retains Consumption Eligibility at 50 Percent Duty: Covered products physically imported before 12:01 a.m. on September 29, 2026, and already held in a bonded warehouse or Foreign Trade Zone, remain eligible for withdrawal for consumption. Such withdrawals are subject to the 50 percent ad valorem duty imposed under Proclamations 11046, 11047, and 11048, as applicable.
• Alcoholic Beverage Scope Is Conditional: For alcoholic beverages, the exclusion applies only where merchandise meets the scope limitations in the Alcohol Annex to Proclamation 11061. Products packaged in bottles, cans, boxes, kegs, or similar direct-to-consumption containers are covered where the annex states 'Packaged.' Alcoholic beverages that do not meet an applicable scope limitation remain subject to the 50 percent ad valorem duty under Proclamation 11046 and are not excluded. Cresthaven reading: importers of record holding alcoholic beverage shipments in transit face a classification determination against the Alcohol Annex scope limitations before the September 29 cutoff.
• HTSUS Coverage Spans Three Product Categories: Covered products include commodities under HTSUS headings 0404 and 1702 through 1703 (dairy and sugar products), 2202 through 2208 (non-alcoholic and alcoholic beverages), and 8711 (motorcycles). The full list of subject classifications appears in the annexes to the three proclamations.

Regulatory Delta

• Presidential Proclamations 11046, 11047, and 11048 previously imposed a 50 percent ad valorem duty on covered Canadian goods. Proclamations 11061, 11062, and 11063 escalate that posture to outright import exclusion, a structural departure from tariff-based restriction.
• The exclusion is unconditional and closes every customs channel simultaneously: ports of entry, bonded warehouses, Foreign Trade Zones, and in-bond movements.
• The proclamations cite continued discrimination against U.S. commerce in alcoholic beverages, motor vehicles, and dairy as the stated basis, invoking the same retaliatory trade-remedy framework used in the prior duty proclamations.

Materiality Classification

HIGH — A binding import exclusion effective within 24 hours of issuance closes all customs channels for covered Canadian goods across three product categories, requiring immediate operational and entry-filing response from importers of record, customs brokers, bonded warehouse operators, and Foreign Trade Zone administrators.
