Canada Tariff Calculator: Price Any US Purchase

What will the counter-tariff add?

Canada's surtaxes on US-origin goods have been in force since September 8, 2026. Pick a category, pick the tariff line your goods fall under, and enter what you will declare. Every rate here is read off the Department of Finance list - 648 tariff items - and the item number behind each figure is shown with it.

Before you trust a number from this page

This is an estimate, not a customs ruling. It multiplies a declared value by a rate taken from a named line of the official list. It does not classify your goods for you, it does not know your supply chain, and it is not the figure on your customs entry. Classification and origin are the importer's responsibility. For anything commercial, confirm both with a licensed customs broker, or ask the Canada Border Services Agency for an advance ruling.

Two questions decide the answer and only one of them is about the product. The surtax applies to goods originating in the United States, which is a question about the factory rather than the brand - so the calculator asks it before it shows you any money. And ten of the 39 categories here carry more than one rate, which is why it asks which line your goods sit on instead of averaging them into a rate that appears on no list at all.

Rates are as of September 10, 2026 and they move. This list lost 254 tariff items - all of fish and seafood - between 26 and 27 August 2026, and remission orders routinely follow a round of counter-tariffs. Check the official Department of Finance list before committing money.

1 What are you importing?

Search the categories

2 Which tariff line?

3 Where was it made?

Is the country of origin marked on the product or its carton the United States?

Yes - it is a US-origin good

No - it was made somewhere else

Not sure yet

The badge on the front does not answer this. An American brand that manufactures in Mexico is outside the measure; a German or Korean brand that manufactures in North Carolina or Tennessee is inside it. The country-of-origin marking is what customs goes on.

4 Value and who is importing

Declared value in Canadian dollars

Use the value you will declare - the value for duty - not the sticker price, if the two differ. If you are converting from US dollars, convert first: this page does no currency conversion and holds no exchange rate.

Who is bringing it in?

Myself, for personal use

A business, commercially

This changes what is worth telling you afterwards, not the arithmetic. Personal exemptions and parcel thresholds matter on one path; value for duty, drawback and classification on the other.

The estimate

Change alerts are being set up and are not running yet, so there is nothing to sign up for at the moment. When they are running you will be able to pick the tariff lines you actually import and get one email if one of them is added, removed or re-rated. No addresses are being collected in the meantime.

This calculator runs entirely in your browser and needs JavaScript. No value you type into it is sent anywhere, with or without scripts. Without scripts, the directory still shows every rate and every tariff item, which is the same information this page does arithmetic on - and the alert sign-up below still works, because it is a plain form.

Where these figures come from

Rates are read from the Department of Finance list of US products subject to counter tariffs at the tariff-item level: 648 items retrieved on September 10, 2026. A build check compares every rate on this site against that list and refuses to publish on a mismatch, including the claims that a category is absent from it. This calculator does arithmetic on those checked rates and holds no rates of its own.

The origin rule, the in-transit carve-out and the 12:01 a.m. start are quoted from the Department of Finance backgrounder for this measure. How the surtax is applied - on the value for duty, in addition to other duties, with GST calculated on the total, and not on goods covered by a personal exemption - is from the Canada Border Services Agency's customs notice for the equivalent 2025 order, because the notice for this one had not been published when this page was built.

This is an independent site, not a government service, and nothing here is legal, customs or tax advice. It is free and it has no accounts. The calculation happens in your browser and no value you type into it - not the price, not the quantity, not the category - is sent anywhere or stored. The one thing this page can send is an email address, and only if you type one into the alert form and submit it.
