Canada Tariff Impact Checker
Screen Your HS Codes Against Canada's Counter-Tariffs on U.S. Goods
Getting a result
What comes back
Every match includes a plain-language description, the rate band, the effective date, and the rate shift, where available. Nothing gets silently dropped; codes with no match still appear in your results, so you can confirm they were actually checked.
This tool answers one question: whether this code is subject to Canada's counter-tariffs and, if so, at what rate. For total landed cost, that is what the Duty & Tax Calculator is for. If you want a second opinion on whether a code is classified correctly to begin with, the HS Lookup Tool handles that.
Checking the other direction? The Tariff Impact Checker covers U.S. Section 301, 232 and 338 measures on goods entering the United States.

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.

The full list of affected tariff items
The tariff item number decides the 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. Chapter 72 and 73 goods, for example, are split between the 50 percent band and the 25 percent derivative band.
Key dates
Announced August 25, in force September 8. That is 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, 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. A shipment that left the U.S. before September 8 should not be subject to the new surtax.
Transit status has to be evidenced, so keep bills of lading, carrier documentation, and export records for anything moving in the first week of September. CBSA publishes the documentary expectations through its customs notices.
A CUSMA certificate does not exempt your goods
One wrinkle: CUSMA status does not shield a product here. The counter-tariffs apply to U.S.-origin goods that meet Canada's country-of-origin rules for marking purposes, which is a different legal test from CUSMA preferential origin.
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 compliance process assumes CUSMA-qualifying goods are covered, that assumption needs to be checked before September 8. Our CUSMA Certificate generator handles the certificate itself, but the certificate is not the test for this measure.
Existing counter-tariffs remain in place
The September 8 measures are additional. Canada's other existing counter-tariffs against the U.S., including autos, remain in place.
If you already pay a counter-tariff on something, do not assume the new list replaces it. Check whether your goods have moved into a higher band, as steel and aluminum have gone from 25 to 50 percent.
How the surtax is calculated
The surtax applies as a percentage of the value for duty, charged on top of any regular customs duty that already applies.
A worked example. Appliances imported from the U.S. with a value for duty of $100,000 CAD, falling in the 25 percent band:
Value for duty: $100,000
Customs duty: applied at your normal tariff rate.
Counter-tariff surtax at 25 percent: $25,000
GST is then calculated on the duty-paid value

What to do before September 8
Four things, and the classification review has the shortest runway.
Get your questions answered
Your Canadian HS codes against Canada's counter-tariff schedule, covering the 648 tariff items effective September 8, 2026, plus the pre-existing counter-tariffs that were never lifted.
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 autos, also remain in place.
Most were removed during 2025, which is why the September 8 measures catch people out. The 648 tariff items announced on August 25, 2026 are new. The counter-tariffs that were never removed, such as autos, have remained in place throughout.
The Canadian importer of record, to CBSA, at the time of accounting. It is not collected from the U.S. exporter. Commercial terms with a supplier do not change who is liable on the entry.
The instrument Canada uses to apply counter-tariffs, charged as a percentage of value for duty on top of regular customs duty. "Surtax", "counter-tariff" and "retaliatory tariff" describe the same charge.

Not the total. Just the rate band per code. Pair it with the Duty & Tax Calculator for the full number.
No, it is a starting point. Anything tied to a real shipment should go through a trade expert.
It means nothing on your list matched our current data. We still show every code so you know it was actually checked, not skipped.
