U.S. to bar imports of certain Canadian heavy motorcycles starting Sept 29, 2026

What is happening

• The President proclaimed an import ban on certain Canadian products effective 12:01 a.m. eastern time on September 29, 2026.

Key details

• What changes: Items listed in the Annex that were previously subject to a 50% ad valorem duty will now be excluded from importation.
• Effective date: 12:01 a.m. ET on September 29, 2026.
• Covered product called out in the Annex: HTSUS 8711.50.00 — motorcycles (including mopeds) with reciprocating internal-combustion engines over 800 cc.
• Exception for prior shipments: Goods imported but not yet entered for consumption or withdrawn from warehouse for consumption before Sept 29, 2026, remain subject to the 50% duty established earlier.

Why this matters

• The action implements a trade restriction under section 338 of the Tariff Act of 1930 and the Trade Act of 1974 in response to findings that Canada maintained discriminatory motor-vehicle tariff measures.
• U.S. Customs and Border Protection (CBP), in consultation with Treasury, Commerce, and the U.S. Trade Representative, is authorized to issue rules and make necessary HTSUS modifications to enforce the ban.

Implementation notes

• Heads of executive departments and agencies must take appropriate measures to carry out the proclamation.
• If the ban is later invalidated for particular imports, those imports will revert to the 50% ad valorem duty under the earlier proclamation.
