Trump Pauses the 50% Canada Tariffs for Three Days — Here’s What Changes for Your Landed Cost
The Section 338 duties were hours from taking effect when Trump announced a three-day pause. What importers should do with the extra 72 hours.
The 50% Section 338 duties on Canadian goods were set to hit at 12:01 a.m. Eastern on August 19. Late Tuesday, hours before the clock ran out, President Trump announced a three-day pause after a round of talks with Canadian Prime Minister Mark Carney. Prime Minister Carney said the tariffs are postponed until the end of the day on August 21, and that “substantial progress has been made, although there is important work still to be done.”
That is a reprieve measured in days, not a repeal. If you import anything from Canada, the planning assumption has not changed — only the date has.
The duties come from three proclamations issued July 20 under Section 338 of the Tariff Act of 1930, a provision that lets the president impose additional duties on countries found to have discriminated against U.S. commerce. It is the first modern-era use of the statute.
The tariff is an additional 50%, and per Al Jazeera the covered basket runs to roughly $20.2 billion in Canadian exports — electronics, industrial machinery, furniture, dairy and wine among them. The headline categories at announcement were motor vehicles, alcoholic beverages and dairy, but the actual lists reach much further: plywood, cement, seeds, clothing, fishing rods, hockey sticks.
Trump said the pause followed a deal “subject to finalization of documents,” and described terms that “will include comprehensive market access for all American goods, economic security commitments, digital trade alignment.” What was actually agreed has not been published. Carney stopped short of announcing retaliation, saying Canada remains ready to engage.
One detail matters more than the diplomacy for anyone doing the accounting. Al Jazeera notes the duties are notable precisely because they apply to goods that qualify for duty-free treatment under USMCA/CUSMA — a break from the carve-outs that have kept most U.S.–Canada trade tariff-free. If your customs broker has told you that USMCA origin protects you here, that is worth a written second look.
Why it matters
Section 338 duties are assessed on the date goods are entered for consumption or withdrawn from warehouse for consumption — not the date they shipped from Canada. A container that left Surrey last week and clears customs on August 24 is exposed. A container that clears on August 20 is not.
That means the three-day pause is not a pause on your exposure. It is a pause on entry timing, and entry timing is the only lever most importers actually control this week.

What this means for small business owners
If you buy from Canada — directly, or through a distributor who does — spend the extra 72 hours on four things:
1. Find out what is actually in transit and when it enters. Ask your broker for a list of shipments with expected entry dates through the end of August. Entry date, not ship date, is what gets you taxed. Anything that can legitimately clear before the deadline should.
2. Re-run landed cost at 50%, not at zero. If you have been quoting Q4 off pre-tariff costs, those quotes are a liability. Build the tariff into landed cost per SKU now so you can see which items go underwater and which absorb it. A 50% duty on a 30%-margin item is not a rounding error.
3. Book the duty where you can see it. Tariffs paid should sit in their own expense or inventory-cost account, not buried in freight or COGS. If negotiations collapse and this runs for two quarters, you will need a clean number for pricing decisions, for lender conversations, and for any refund claim if the duties are later modified or withdrawn.
4. Do not sign a fixed-price customer contract this week without a tariff clause. The proclamations can be modified or withdrawn as a result of further negotiations, which cuts both ways — you can be repriced upward on 24 hours’ notice.
For context on what this class of cost does at scale: a Center for American Progress analysis published in March 2026 found small-business importers paid an average of $306,000 more in tariffs over the March 2025–February 2026 period, roughly $25,000 a month per business, across about 236,000 affected firms. That is the order of magnitude a 50% duty operates in.
The bottom line
Three days is enough time to know your exposure and almost no time to change it. Get the entry-date list from your broker today, reprice off 50%, and treat August 21 as the real deadline until someone publishes an actual agreement. Deals “subject to finalization of documents” have a way of not finalizing.
