View Chapter 1How to read an HTS code
Each pair of digits narrows the product. Take a placeholder code, 0000.00.00.00:
- 2 digits, the chapter: the broad family of goods.
- 4 digits, the heading: a product type within the chapter.
- 6 digits, the subheading: the international HS code, shared with most countries.
- 8 digits, the US tariff line: where the base duty rate is set.
- 10 digits, the statistical suffix: the code you file on a US entry.
The base rate on the line is only part of the duty. Section 301, Section 232 and Section 338 measures sit in Chapter 99 and stack on top by origin; the tariff calculator adds them up for you. We do not classify products; confirm your code with a licensed broker.
HTS FAQ
What is an HTS code?
An HTS code is the number the US uses to classify an imported product and set its base duty. It comes from the Harmonized Tariff Schedule of the United States, which the US International Trade Commission publishes at hts.usitc.gov. Customs uses the code on every entry to decide the duty rate, the statistics and any extra measures.
How many digits is an HTS code?
Ten. The first six digits are the international Harmonized System code shared by most countries. Digits seven and eight are the US tariff line that carries the duty rate, and digits nine and ten are a statistical suffix. You file the full ten-digit code; the official text is on hts.usitc.gov.
What is the difference between HS and HTS?
HS is the six-digit Harmonized System maintained by the World Customs Organization and used by over 200 economies. HTS is the US schedule built on it, adding four US digits and the US duty rates. Two countries agree at six digits and often differ after that, so a US entry needs the US code.
Where does the HTS come from?
The US International Trade Commission maintains and publishes it at hts.usitc.gov, in a basic edition each year followed by numbered revisions as laws and proclamations change it. This page reads the latest verified USITC release (2026 Revision 22), imported into our database.
Does the HTS rate include Section 301?
No. The rate printed on an HTS line is the base duty. Section 301, Section 232 and Section 338 duties are separate Chapter 99 headings that apply by country of origin and stack on top. Our Chapter 99 guide explains them, and USITC lists the headings in Chapter 99 of the HTS.
How often does the HTS change?
Several times a year. USITC publishes a basic edition each January and then numbered revisions, and we have imported 8 verified 2026 releases so far. Each revision can add, split or re-rate lines, so check the release named at the top of this page against hts.usitc.gov.
