Starting at 12:01 a.m. on September 8, 2026, Canada begins charging new counter-tariffs of 15%, 25%, and 50% on a defined list of U.S.-made goods. If you sell on Amazon.ca — or ship U.S.-sourced inventory into Canada through any channel — your landed cost on affected SKUs is about to move, whether or not you’ve priced for it yet.
Most sellers hear “steel and aluminum” and assume this doesn’t touch them. Then they check the actual tariff item list and find their cookware, small appliances, or packaging materials sitting right on it.
Why Canada Is Doing This
This is a direct response, not a new policy direction. On August 22, 2026, the United States imposed a 50% tariff under Section 338 on $27.6 billion worth of Canadian goods. Canada’s government said it would match that dollar-for-dollar, and the resulting counter-tariff list — published by the Department of Finance on August 25 and already revised once, on August 26, when seafood and fish were pulled off and replaced with other items — is the result.
Treat that list as a moving document. It changed within 24 hours of being published once already, and there’s no reason to assume it’s final now.
The Rates, By Category
Canada’s countermeasures cover roughly $27.6 billion in U.S. imports, with rates set to mirror whatever the U.S. charges on the equivalent Canadian product under Section 338 and Section 232. Based on the official tariff item list, here’s how it breaks down:
| Rate | What it covers | Why it matters to sellers |
| 50% | Steel and aluminum (up from Canada’s prior 25% rate), most dairy powders/whey/casein, plastics and household goods, cosmetics, most paper and pulp products, most apparel | The heaviest hit — metal components, cookware, tools, packaging, and personal care products all land here |
| 25% | Cheese, softwood lumber (pine, fir, spruce, S-P-F), certain steel/aluminum derivatives, toilet paper, some carpets | A meaningful jump, especially for anything bulky or low-margin |
| 15% | Scattered items elsewhere on the schedule | Smaller individually, but still enough to erase a thin Amazon.ca margin |
A few structural notes:
- Country-of-origin rule: The surtax only applies to goods that qualify as U.S.-origin under Canada’s CUSMA marking regulations — not simply anything shipped from a U.S. address.
- In-transit exemption: Goods already in transit to Canada on September 8 are not subject to the new tariffs.
- Where to verify: Cross-check your HS codes against the Finance Canada tariff item list directly — not a news summary, including this one — since the list can still change before the effective date.
The Part Most Coverage Skips: Duty Compounds on Every Border Crossing
Here’s what actually catches sellers off guard. If a component crosses the U.S.-Canada border more than once before it reaches a customer — say, raw material into the U.S., partial assembly, then a finished good shipped to an Amazon.ca or Canadian FBA warehouse — the tariff can apply at each crossing, not once at the end.
That means the sticker rate on your product category understates your real exposure if your supply chain isn’t a single clean hop. This is where a foreign-trade zone or bonded warehouse strategy can matter: goods that get reworked or re-exported inside a zone can defer or reduce the duty that would otherwise apply on each pass through the border.
Practical step: pull your bill of materials and count how many times a component or sub-assembly physically crosses the border before it reaches a Canadian warehouse. If you don’t know the answer, that’s the first thing to find out — either yourself or through your customs broker or Amazon agency.
What This Actually Does to Your Landed Cost
Percentages don’t mean much until they’re converted into per-unit numbers. Here’s a simple version:
Say you ship $40,000 worth of a U.S.-made product into Canada, and it falls in the 25% tier. That’s $10,000 in new duty on a single inbound shipment. If that shipment is 2,000 units at a $20 landed cost, the tariff adds $5 per unit — a 25% jump on a product that might only be earning $6–8 in margin today.
At the 50% tier, the same math roughly doubles: a $40,000 shipment picks up $20,000 in duty, or $10 a unit — a number most Amazon.ca listings simply can’t absorb without a price change.
Don’t estimate this with the tariff rate alone. Run your own shipment size, unit count, and landed cost through the math above (or a tariff calculator) to find your new breakeven price before September 8, not after.
Should You Rush Inventory In Before September 8?
If a shipment is ready, the SKU is on the tariff list, and it can legitimately clear before the deadline, yes — shipments that cross the border before the effective date are covered under the old rate, and goods already in transit on the day it takes effect are exempt from the new tariffs entirely.
That said, don’t panic-ship a year of inventory to beat a date. Extra storage costs, cash tied up in stock, and the risk that rates shift again in either direction all cut against overcorrecting.
A better approach: prioritize your highest-margin, highest-velocity Canadian SKUs for near-term shipment, and let slower movers wait until the list — and the broader trade situation — stabilizes.
If cross-border fulfillment friction is a recurring issue for you, this is also a good moment to revisit how you’re using FBA’s cross-border remote fulfillment options, since where inventory physically sits changes your exposure to measures like this one.
Raising Prices Without Losing the Buy Box
Amazon doesn’t stop you from adjusting prices to cover higher landed costs — but it does watch how your price compares to external reference points, and a price that looks too far out of line risks losing the featured offer or getting suppressed.
The safer approach is incremental: move price in small steps over a few weeks and watch conversion rate, session value, and featured-offer status as you go, rather than jumping straight to your new target price.
It’s also worth revisiting ad spend at the same time. A campaign that was marginally profitable before the tariff can turn a SKU net-negative once landed cost rises — so any price adjustment should come with a fresh look at what you’re paying to acquire that sale.
The Bigger Picture
This counter-tariff round is the latest escalation in a U.S.-Canada trade relationship that broke down over the summer of 2026, and neither side is currently signaling a quick resolution. That argues for treating this as your operating environment through the rest of the year rather than a short-term disruption to wait out — which means the sellers who reprice, restructure sourcing, or adjust fulfillment now will be in better shape than those who wait for a headline to tell them it’s over.
