Canadian Tariffs on U.S. Goods
Check your HS codes against the counter-tariff list
Canadian tariffs on U.S. goods are applied at the tariff item level, so your HS classification determines your rate. Enter the Canadian HS codes you import under, and the tool tells you whether your goods appear on the counter-tariff list, which rate applies, and what the rate was before September 8.

Codes that do not match anything on the list are shown too, so you can see that every code you entered was actually reviewed.
This tool checks the Canadian direction, meaning what Canada charges on goods arriving from the U.S. If you need the opposite direction, our tariff impact checker for U.S. tariffs on Canadian goods covers Section 301, 232 and 338 measures on goods entering the United States.
Don't know your codes? They are on your customs entry documents and past broker invoices, or you can ask whoever clears your shipments to send the list. It takes minutes. Use the full 10-digit codes where available, because a 6-digit code can span multiple rate bands.
Not sure your code is right in the first place? Run it through our Canadian HS classification tool before you rely on the result.
What Canada is charging on U.S. goods from September 8
From 12:01 a.m. on September 8, 2026, Canada is applying counter-tariffs of 15, 25, or 50 percent to $27.6 billion in goods imported from the United States, covering 648 tariff items. Goods subject to 50 percent include steel and aluminum, furniture, and clothing and apparel. Goods at 25 percent include appliances and dairy.
Each product's rate matches the corresponding U.S. rate on the same goods. Canada drew the list from products already targeted by U.S. Section 338 and Section 232 tariffs.
If you import from the U.S., you have under two weeks to work out your exposure and act on it.
Rate
Goods included
50%
Steel and aluminum products, which were previously subject to a 25 percent counter-tariff. Furniture. Clothing and apparel.
25%
Appliances. Dairy products including cheese. Certain steel and aluminum derivative products.
15%
Electronics and other products.
Across tiers
Agricultural equipment, pulp and paper, plastics and construction materials appear across the rate bands depending on the specific tariff item.
The sectors Canada named as the focus of the measures are steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. Those are the industries the government says were most affected by U.S. tariffs.
Treat the table above as orientation, not as the answer for your shipment. The measures are published at the tariff item level, and two products that sound similar can fall into different rate bands.
The full list of affected tariff items
The tariff item number decides your rate, not the sector description. Finance Canada publishes the counter-tariffs as a schedule of tariff items to be read alongside the Schedule to Canada's Customs Tariff.
Where a product sits in a chapter that is only partly covered, the specific item governs. Steel and aluminum goods, for example, are split between the 50 percent band and the 25 percent derivative band.
Key dates
The measures were announced on August 25 and take effect on September 8, which leaves a narrow planning window.

August 22, 2026
U.S. tariffs of 50 percent took effect on $27.6 billion of Canadian goods.
August 25, 2026
Canada suspended trade negotiations and confirmed it would match the new U.S. tariffs dollar for dollar, rate for rate. Finance Minister François-Philippe Champagne announced the counter-tariffs alongside a $7.5 billion support package.
September 8, 2026, 12:01 a.m.
Canada's counter-tariffs apply to goods imported from the U.S.
What is exempt, and what is not
Two exemptions matter for the September 8 measures, and one widely held assumption about CUSMA is wrong.

Goods in transit are exempt
Canada's countermeasures do not apply to U.S. goods already in transit to Canada on the day the measures come into force. If a shipment left the U.S. before September 8, it should not be subject to the new surtax.
You will need to be able to provide evidence of transit status, so keep your bills of lading, carrier documentation, and export records for anything moving in the first week of September. Shipment timing over that week is worth planning deliberately rather than leaving it to chance.
The Canada Border Services Agency publishes administrative details in its customs notices, where the documentary expectations are spelled out.

A CUSMA certificate does not exempt your goods
Holding a valid CUSMA certificate of origin will not exempt your goods from counter-tariffs. The counter-tariffs apply to U.S.-origin goods that meet Canada's country-of-origin rules for marking purposes. That is a different legal test from the CUSMA preferential origin test. A shipment can qualify for duty-free treatment under CUSMA and still be marked as a product of the U.S., which means the surtax applies.
If your team has been working under the assumption that CUSMA-qualifying goods are covered, that assumption needs to be checked against the marking rules before September 8.

Existing counter-tariffs remain in place
The September 8 measures are additional. Canada's other existing counter-tariffs against the U.S., including those on autos, remain in place.
So if you already pay a counter-tariff on something you import, do not assume the new list replaces it. Check whether your goods now fall into a higher tariff band, as steel and aluminum have moved from 25 to 50 percent.
How the surtax is calculated
The surtax applies as a percentage of the value for duty of your goods, charged on top of any regular customs duty that already applies.
A worked example — appliances from the U.S., value for duty $100,000 CAD, 25 percent band
Value for duty
$100,000
Regular customs duty
Applied at your normal rate for the tariff item
Counter-tariff surtax at 25 percent
$25,000
GST
Calculated on the duty-paid value
Getting your value for duty right matters more than usual once a 50 percent surtax is in play, because an error that was worth a few hundred dollars in duty becomes worth thousands. Our value for duty page covers the valuation methods and where importers commonly go wrong.

Surtax amounts flow through your CBSA accounting in the normal way, meaning they appear on your statement of account and count against your financial security. If you are close to your posted security limit, a 50 percent surtax on a regular shipment can push you over it.
Working out what September 8 costs you?
Our trade team can screen your tariff items against the counter-tariff list and tell you where your real exposure sits.
What to do before September 8
Four things, and the classification review has the shortest runway.
01
Screen your catalogue against the tariff item list
Codes assigned years ago, often by someone no longer at the company, are the usual source of unexpected exposure. Two weeks is enough to screen a catalogue and correct errors. It is not enough after an entry has been filed.
02
Check transit timing on anything already ordered
Goods in transit on September 8 are exempt. Anything you can get moving before then avoids the surtax, and anything arriving after it does not.
03
Model the cost change before you reprice
A 15 percent surtax and a 50 percent surtax are different commercial problems. Work out which of your SKUs are affected and by how much before you commit to customer pricing.
04
Assess whether relief applies
Remission, duty drawback and duty deferral each work in different circumstances, and none of them are automatic.
Frequently asked questions
Does Canada impose tariffs on U.S. goods?
Yes. Starting September 8, 2026, Canada will apply counter-tariffs of 15, 25, or 50 percent to 648 tariff items covering $27.6 billion in imports from the United States. Each product's rate matches the U.S. rate on the equivalent goods. Earlier counter-tariffs, including those on autos, also remain in place.
Didn't Canada remove its counter-tariffs?
Canada removed most of its counter-tariffs on U.S. goods during 2025, which is why the September 8 measures catch people out. Those earlier removals do not apply here. The 648 tariff items announced on August 25, 2026, are new, and the counter-tariffs that were never removed, such as autos, have remained in place.
Who pays the counter-tariff?
The Canadian importer of record pays it to CBSA at the time of accounting. The surtax is not collected from the U.S. exporter. If you are the importer of record on the entry, it is your liability, regardless of what your commercial terms with the supplier say.
What is a surtax?
A surtax is the instrument Canada uses to apply counter-tariffs. It is charged as a percentage of the goods' value for duty, on top of any regular customs duty. In everyday use, "surtax", "counter-tariff" and "retaliatory tariff" describe the same charge.
What does Canada still have tariffs on?
The 648 tariff items on the September 8 list, plus the pre-existing counter-tariffs that were never lifted, including autos. The September 8 measures focus on steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics.
Are goods already on the water exempt?
Yes, if they were in transit to Canada before the measures came into force on September 8. Keep documentation that establishes when the shipment left the United States.
Is this legal or trade advice?
No. Treat it as a starting point, not a final answer. For anything tied to an actual shipment, talk to one of our trade experts.
Screen your codes before September 8
Classification determines your exposure, and correcting it costs far less now than it does after an entry is filed. Our trade team screens tariff items against the counter-tariff list, checks whether marking rules put your goods within scope, and determines whether remission or drawback is worth pursuing.
