How to Find the HTS Code for Your Product

November 8, 2026

Reviewed by Sasha Božič, Licensed Customs Broker

To find the HTS code for a product, describe the product precisely, search the Harmonized Tariff Schedule published by the U.S. International Trade Commission, work down from heading to 10-digit number using the General Rules of Interpretation, and check CBP rulings on similar products. The first six digits are shared internationally. The last four are specific to the U.S.

Step 1: Describe the product

Write down what it is, what it is made of, how it works, what it is used for and whether it is a part, a complete article or a set. Most classification mistakes start with a vague description.

Step 2: Search the schedule

Search the HTS at hts.usitc.gov by product terms, then read the section and chapter notes for the headings that come up. Notes often include or exclude products explicitly.

Step 3: Apply the General Rules of Interpretation

  • GRI 1: Classify by the terms of the headings and the notes.
  • GRI 2: Unfinished or unassembled articles and mixtures.
  • GRI 3: When more than one heading could apply, the most specific description wins, then essential character.
  • GRI 6: Apply the same logic at the subheading level.

Step 4: Check CBP rulings

Search CBP's CROSS database for rulings on similar products. Rulings show how CBP has applied the rules.

Step 5: Confirm the duty

At the 10-digit level, read the general rate, any special rates for trade programs, and any Chapter 99 duties tied to that number. See HTS Chapter 99.

Frequently asked questions

Is the HTS code the same as Schedule B? No. Schedule B numbers are used for exports. The first six digits usually line up.

Can I use my supplier's code? Treat it as a starting point. Foreign codes often match at six digits and not at ten.

What if it is still unclear? Request a binding ruling.
