The US-Canada tariff impact on Amazon sellers begins September 8, when Canada applies 15, 25, and 50 percent duties to more than 700 American goods. Steel and aluminum move to 50 percent, while appliances and dairy sit at 25 percent.
Your Amazon.ca prices were set before any of this started, and they are about to be wrong. Most sellers read this as a steel and auto story and move on, then check the tariff item list and find their cookware, their small appliance, or their packaging on it.
Here is the part that catches people. The duty does not land on your P&L in one clean line, because it hits at the border on the value you declare, which means your cost per unit changes before a single order comes in.
I run a 500-person agency that manages more than 400 brands and over $1.2 billion in ecommerce revenue, and cost shocks like this one are where I see good operators lose a quarter. So let me walk you through what changed, what it does to your landed cost, and what I would do this week.
Canada Retaliatory Tariffs Start September 8 at 15, 25, and 50 Percent
Canada is matching US rates rather than inventing new ones. Supply Chain Dive reported that starting September 8, Canada begins charging 15, 25, or 50 percent on US goods that mirror the rates already faced by products targeted under Section 338 and Section 232 tariffs.
The categories matter more than the politics here. Supply Chain Dive listed steel, dairy products, appliances, agricultural equipment, electronics, and pulp and paper as the focus areas, and Ottawa paired the measure with a $7.5 billion support package for affected Canadian businesses.
One detail moved after the first announcement. Canada’s Department of Finance pulled seafood and fish products off the list, which is a good reminder that the schedule is live and can shift again before it takes effect.
Steel and aluminum carry the top rate. Those imports face 50 percent, up from the previous 25 percent Canadian levy, while appliances, dairy products, and certain steel and aluminum derivatives sit at 25 percent.
The official product list at the tariff item level lives with the federal government, and the Canada Department of Finance counter-tariff list puts the covered volume at $27.6 billion in US imports. That is the document to check your HS codes against, not a news summary.
| Rate tier | Example categories | What it means for sellers |
|---|---|---|
|
50%
|
Steel, aluminum, and select derivatives
|
Metal housings, cookware, tools, and hardware take the heaviest hit
|
|
25%
|
Appliances, dairy, certain steel and aluminum derivatives
|
Small kitchen and home goods see a meaningful landed cost jump
|
|
15%
|
Additional listed goods across the schedule
|
Smaller but still enough to erase a thin Amazon.ca margin

Effective time: 12:01 a.m. on September 8, 2026. Goods already in transit to Canada when the measure takes effect are not covered.
Why the US-Canada Trade Dispute Broke Down and What It Signals Next
The Guardian reported that Prime Minister Mark Carney rebuked Washington over insults and online mockery, saying of the conduct, “It is beneath their office.” Carney tied any resumption of talks to a change in tone from US officials, and Al Jazeera carried the same remarks from his Ottawa press conference.
The US side is not signaling a quick fix either. US Trade Representative Jamieson Greer told Politico that no trade negotiations are happening right now, and he framed the standoff as a bigger emergency for Canada than for the United States.
Both capitals also disagree about why the talks fell apart. Washington points to Canadian demands on things like heavy-duty truck taxes, while Ottawa points to late terms it called uneconomic and to friction over French-language protections.
My read is that this dispute has no visible off-ramp, so I would treat Trump Canada tariffs and the counter-tariffs as your operating environment through Q4 rather than a two-week disruption. You are not waiting out a headline so much as repricing a catalog while Canada-US trade relations stay unsettled.
The Border Is a Supply Chain, and Duty Compounds on Every Crossing
This is the piece almost nobody covering North American trade tariffs is explaining well, and it is the one that costs sellers the most.
CNBC reported that supply chain analysts see the real exposure in products that cross the border more than once, because a tariff applies again on each crossing rather than a single time. Dan Luttner of NEOS by Argon & Company described the market reaction to the new wall as a reflex, saying, “The stock pop is a headline reflex, honestly.”
CNBC also quoted University of Wyoming business dean Scott Beaulier on aluminum, where the US stays heavily import-dependent, and Canada supplies a large share of primary metal. New smelter capacity takes years to build, so the duty raises input costs for American manufacturers long before domestic supply can replace anything.
There is a compliance angle too. Melissa Irmen of the National Association of Foreign-Trade Zones told CNBC that companies are already shifting sourcing decisions, and that a foreign-trade zone lets a business defer or reduce duty when imported material is re-exported or reworked into a different product.
For a mid-market Amazon brand, the practical version is simpler. Pull your bill of materials and count how many times a component physically crosses the border before it reaches an FBA warehouse, or have your Amazon agency map it for you.
Every crossing is a separate duty event. That is where the tariff impact on businesses stops being an abstraction and starts showing up in your cost per unit.
What the US-Canada Tariff Does to Your Landed Cost
Let me put numbers on it, because percentages do not mean anything until you convert them to your own math.
Say you ship $50,000 of US-made stainless cookware into Amazon.ca, and the item sits in the 25 percent tier. That is $12,500 in duty on one inbound shipment.
Now scale it to a unit. If that shipment holds 2,500 units at a $20 landed cost, the duty adds $5 per unit, which is a 25 percent cost increase on a product you may only be earning $6 on.
At the 50 percent tier, the math gets ugly fast. The same shipment carries $25,000 in duty, and most Amazon.ca listings do not have the margin to absorb $10 a unit quietly.
Run your own version before September 8 using the US tariff price calculator rather than estimating. The number you need is not the tariff rate; it is your new breakeven price.
Should You Ship to Amazon.ca Before September 8?
If the inventory is ready and the SKU is on the list, yes, and the reason is specific. Canada’s measure does not apply to US goods already in transit on the day it takes effect, so shipments that cross before the deadline clear at the old rate.
I would not panic-ship a full year of inventory to beat a date. Storage costs, cash tied up in stock, and the risk of a rate change in either direction all argue against overcorrecting.
What I would do is prioritize. Move your highest-margin, highest-velocity Canadian SKUs now and let the slow movers wait for a clearer picture.
If cross-border fulfillment is the friction point, remote fulfillment with FBA changes where inventory sits and how orders reach Canadian buyers, which changes your exposure. That is a structural fix rather than a scramble.
Raising Prices Without Losing the Buy Box
Amazon does not stop you from raising prices to cover an e-commerce tariff. What it does is watch whether your price looks fair against outside reference points.
Push a price too far above the external market, and you risk losing the featured offer or seeing the listing suppressed entirely. That is a self-inflicted wound on top of a tariff.
So I move prices in steps rather than one jump. Small increases spaced over a few weeks let you watch conversion, session value, and featured offer status without guessing.
Advertising is the other lever people forget. When cost per unit rises, a wasteful campaign stops being an inefficiency and becomes the thing that takes the SKU negative, which is why I would pair any price move with a hard look at ad spend.
For the full pricing playbook on this, we already broke down handling Amazon tariff price hikes in detail.
