US import duty calculator
Enter an HS code, the country of origin and the customs value. You get an estimate of the US import duty, the rate as the tariff schedule publishes it, and which rate column applies — with the reason.
How it works
From a code to an estimate, in plain terms.
- 1
Enter three things
The HS or HTS code for your goods, the country they come from, and their customs value in US dollars. No account, no email.
- 2
Matched to the US tariff schedule
The code is looked up in the Harmonized Tariff Schedule of the United States as the U.S. International Trade Commission publishes it. If a 6-digit code covers lines with different rates, you pick the line.
- 3
The origin decides the rate
General, Special (free-trade agreements and preference programs) or Column 2 — the country of origin decides which one applies, and the result tells you why.
- 4
An estimate with its source
For a percentage rate you get the duty on your value, the rate as published and the tariff revision it came from.
Where it stops
What it will not do.
Worth knowing before you put a number in a quote.
- It is an estimate, not a determination. What you owe is decided at entry — confirm the classification and the rate with your licensed customs broker.
- Per-unit and compound rates, such as cents per kilogram, depend on quantity rather than value. The calculator shows the published rate and tells you it cannot give a dollar figure.
- Section 301 and Section 232 additional duties, antidumping and countervailing duties, quotas, and fees such as the merchandise processing fee are not included.
- A preferential rate needs a valid claim and proof of origin at entry. Without them, the General rate applies.
- Imports into the United States only. Senda files nothing with US Customs and Border Protection or any other customs authority.
Questions
What people ask us.
How is US import duty calculated?
For most goods, duty is the customs value multiplied by the percentage rate for the goods' tariff line: 8% on USD 10,000 is USD 800. Which rate applies depends on the country of origin — the General rate for most countries, a lower Special rate under a free-trade agreement or preference program, or the Column 2 rate for the few countries without normal trade relations. Some lines charge per unit instead, which depends on quantity rather than value.
Is this the duty I will actually pay?
It is the rate the tariff schedule publishes for that line and origin. Section 301 or 232 additional duties, antidumping and countervailing duties, and fees can apply on top, and a listed rate is not always the rate collected. Treat the figure as an estimate and confirm it with your licensed customs broker before you rely on it.
What is the difference between an HS code and an HTS code?
The first six digits are the international Harmonized System, shared by most countries. The United States adds digits to make an 8-digit tariff line, plus a 2-digit statistical suffix. Duty rates are set at the 8-digit level, so one 6-digit code can cover lines with different rates — when that happens, the calculator asks you to choose the line.
Does it apply free-trade rates such as KORUS or USMCA?
Yes, when the tariff line lists that agreement in its Special column and you choose the partner country as the origin. Many lines list KORUS for goods of South Korea, for example. The preferential rate still needs a valid claim and proof of origin at entry; without them, the General rate applies.
Which version of the tariff schedule does it use?
The Harmonized Tariff Schedule of the United States as published by the U.S. International Trade Commission. Every result names the revision and its release date, and says whether we have confirmed it is still the current one.
Is it free? Do I need an account?
It is free and needs no account. If your team wants duty estimates in the same workspace as its orders and shipments, that is what Senda is for — the form under each result reaches a person, not a mailing list.
