TariffsSTATUS: SUSPENDED — not in effect, not cancelled

Client Advisory: Canada Section 338 50% Tariffs Suspended Through Aug 22, 2026

Published August 19, 2026By ABD Legacy LLC

What happened: On Tuesday evening, August 18, 2026 — hours before the 50% duties were due to take effect — President Trump announced a three-day suspension after the U.S. and Canada reached a preliminary agreement, saying the two countries have a deal "subject to the finalization of documents." Canadian Prime Minister Carney confirmed the pause. The underlying Section 338 proclamations (signed July 20, 2026) have not been withdrawn or amended.

What importers should do now

• Do not finalize an Aug 19 duty accrual. The 50% duty did not take effect at 12:01 a.m. ET on August 19, 2026. Remove or hold any accrual booked for entries as of Aug 19 — do not remit the 50% duty on the original deadline basis.
• Prepare for possible Aug 22 implementation. The new effective date is Saturday, August 22, 2026 at 12:01 a.m. ET. Model the 50% duty on Canadian-origin autos, alcohol, and dairy (and other covered categories) for entries on or after that time, and confirm with your customs broker how they will handle entries if talks collapse.
• Hold release decisions on border-line shipments. If a shipment clears customs between now and Aug 22, the rate that applies is the rate in effect at the time of entry — the 50% duty is currently suspended, but that can change Saturday morning.
• No in-transit grace period has been announced for either the original Aug 19 date or the new Aug 22 date.

Key dates

• Jul 20, 2026 — Three Section 338 proclamations signed: 50% additional duty on Canadian motor vehicles, alcohol, and dairy (~$20B of exports).
• Aug 18, 2026 (Tue, evening) — Trump announces 3-day suspension; Carney confirms. New effective date: Aug 22.
• Aug 19, 2026 (Wed, 12:01 a.m. ET) — Original effective date — the duty did NOT take effect; suspension active.
• Aug 19–21, 2026 — Three-day suspension window; U.S.–Canada deal talks ongoing.
• Aug 22, 2026 (Sat, 12:01 a.m. ET) — New effective date: deal finalized, suspension extended, or the 50% duty takes effect (all still open as of Aug 19).

Check back for the final deal outcome. The two governments are finalizing a broader trade agreement; we will update this advisory the moment the deal is signed, extended, or allowed to lapse.
