About this tool

US import duty follows the USITC Harmonized Tariff Schedule (HTS, https://hts.usitc.gov) and official CBP guidance (https://www.cbp.gov). Look up the full official HTS code and the rate that applies, including whether a Section 301, 232 or other measure also applies, then enter that rate here. General rates, Section 301, IEEPA or other policy rates are not built in, and this page is not a customs entry. Confirm the customs-value basis with official CBP rules.

How the formula works

If no customs value is entered, customs value = goods + freight + insurance. Duty = customs value × the official rate you enter from the HTS or CBP. Other import taxes can be estimated if you enter a rate. Section 301 or other additional duties are not added unless you include them in the rate or other fees you enter.

FAQ

Why is there no built-in US tariff table?

The HTS has thousands of 8- and 10-digit codes, and measures such as Section 301 can change the rate. Current rates must be looked up at https://hts.usitc.gov; this page will not invent a database.

Do I have to add Section 301 myself?

Yes. If an official query shows a Section 301 or other additional duty, include the combined applicable rate in the official duty rate, or enter the extra amount as other import fees. This page does not apply policy rates automatically.

Where do I look up an HTS code?

Use the official USITC query at https://hts.usitc.gov. This site’s HS lookup only covers Harmonized System chapters and is a starting point, not a full HTS database.
