Customs Duty Calculator

Estimate import duty plus the processing fees and sales tax that turn a shipment's value into its true landed cost — for imports into the US, Canada, or Mexico. Enter your customs value and duty rate, or flip the USMCA toggle to see the duty-free result for qualifying North American goods.

Not sure if your goods qualify for duty-free treatment? Run them through the USMCA Checker first, then come back to price the rest of the landed cost.

Breakdown

Estimate only. Duty depends on exact HS classification and origin; processing fees and sales tax (MPF, HMF, GST, IVA) follow each country's rules and change over time. This is a planning estimate, not customs advice — confirm with your broker or the tariff schedule.

How import duty and landed cost are calculated

Customs duty is only one line of your true import cost. Landed cost is the goods value plus duty plus the government's processing fees and sales tax. The duty itself is the customs value multiplied by the duty rate for your product's HS code — and that rate drops to zero when the goods qualify for duty-free origin under USMCA / CUSMA / T-MEC.

The fees stacked on top of duty

How to lower your duty legally

The biggest lever is origin: goods that meet the USMCA rules of origin move duty-free between the US, Canada, and Mexico. Correct HS classification matters too — a misclassified product can sit in a higher-duty bracket than it should. And the customs value you declare (transaction value, and whether freight/insurance are included) directly drives the duty base. Use the USMCA Checker to confirm origin, get the right HS code from your broker, and this calculator to price the rest.

Customs Duty — Frequently Asked Questions

How is customs duty calculated?

Duty is the customs value of the goods multiplied by the duty rate for their HS classification. On top of duty, the importing country adds processing fees and sales tax (US MPF/HMF, Canadian GST, Mexican IVA) to reach the total landed cost.

Does USMCA make my shipment duty-free?

If your goods meet the USMCA / CUSMA / T-MEC rules of origin, duty between the US, Canada, and Mexico is 0% — and US imports also skip the MPF. They aren't automatically free, though: you need to qualify under the rules of origin and have a valid certification. Check eligibility with our USMCA Checker.

What is the Merchandise Processing Fee (MPF)?

The MPF is a US customs fee of roughly 0.3464% of the shipment value on formal entries, subject to a per-entry minimum and maximum. USMCA-qualifying goods are exempt. Ocean shipments also incur a 0.125% Harbor Maintenance Fee.

Do I pay sales tax on imports into Canada or Mexico?

Yes. Canada applies 5% GST (plus provincial tax in some provinces) on the duty-paid value. Mexico applies 16% IVA on the value plus duty plus the DTA processing fee. Both are separate from customs duty.

Where do I find my exact duty rate?

Look up your product's HS code in the importing country's tariff schedule (the US HTS, the Canadian Customs Tariff, or Mexico's TIGIE). Your customs broker can confirm the classification. The category presets in this tool are typical figures for planning, not official rates.
