- 1Certain Canadian goods banned from import starting September 29, 2026
- 2Goods may previously have been subject to an additional 50% tariff
- 3Scope covers Canadian products listed in the attachment
- 4Some goods in transit before the effective time may still receive the original tariff treatment

What happened?
A U.S. government notice states that certain Canadian goods will be excluded from U.S. imports starting at 12:01 a.m. Eastern Time on September 29, 2026. The goods may previously have been subject to an additional 50% tariff, but the new measure will change the treatment of certain products from high-tariff imports to prohibited imports. The notice states that the specific scope is determined by the Canadian products listed in the attachment. Goods imported before the measure takes effect but not yet entered for consumption, or not yet withdrawn from a bonded warehouse, may still be handled under the original 50% tariff. The change directly affects cross-border ecommerce sellers of Canadian alcoholic beverages, dairy products and related foods, motorcycles, and automotive parts, and may also affect businesses using U.S. overseas warehouses, DDP logistics, platform tax collection, or third-party importer services. Sellers need to check whether their products appear on the attachment based on their HTS codes, stop shipping restricted SKUs to the United States, and confirm the handling of in-transit inventory with customs brokers, logistics providers, and overseas warehouses.
What does this mean for cross-border sellers?
Starting September 29, 2026, certain Canadian goods listed in the attachment will shift from high-tariff treatment to import prohibition, potentially causing customs failures, shipping interruptions, and overseas-warehouse fulfillment problems for U.S. stores. Goods imported before the effective time but not yet entered for consumption or withdrawn from a bonded warehouse may still be handled under the original 50% tariff, so sellers should verify product codes and in-transit inventory status at the same time.
What should sellers do now?
- 1Compare each SKU against the attachment by HTS code, covering Canadian alcoholic beverages, dairy products and related foods, motorcycles, and automotive parts sold through U.S. stores; create restricted, pending-review, and not-listed tables and retain the coding basis.HS duty estimate
- 2Immediately suspend shipments of potentially restricted SKUs to the United States and notify fulfillment parties using U.S. overseas warehouses, DDP logistics, platform tax collection, or third-party importers; retain the shipment-suspension list and notification records as evidence of completion.
- 3Contact customs brokers, logistics providers, and overseas warehouses to verify, shipment by shipment, goods imported before September 29 that have not completed entry for consumption or have not been withdrawn from a bonded warehouse; prepare a confirmation table for original 50% tariff treatment.
- 4Enter Canadian goods in transit that may still be handled under the original 50% tariff into profit calculations, separately verify costs and saleability for the related U.S.-store SKUs, and produce a decision table for continuing fulfillment, pausing, or rerouting.Profit calculator
