How do I find the HTS code for a product?

Updated 2026-10-17 · Data and API builders · by CyberMax

Short answer

Start from what the product is and is made of, find its chapter in the Harmonized Tariff Schedule (hts.usitc.gov), narrow to the 4-digit heading and 6-digit subheading using the headings' exact wording and the chapter notes, then pick the 8-digit US tariff line (which sets the duty rate) and the 10-digit statistical suffix. For a binding answer, US Customs (CBP) issues free rulings; search past rulings in CROSS.

  1. Describe the product precisely: what it is, what it does, what it is made of (for example "smartphone", not "electronics").
  2. Search hts.usitc.gov by keyword and read the chapter and section notes for the chapters that come up.
  3. Choose the heading (4 digits) and subheading (6 digits) whose wording fits; the first 6 digits are the same worldwide.
  4. Choose the US 8-digit line, which sets the general duty rate, then the 10-digit suffix for reporting.
  5. Check extra duties: Section 301 for many goods from China, plus any other trade remedies.
  6. Search CBP's CROSS rulings database for the same product to confirm.

Copy-paste code

Look up a code's rate and Section 301 status (Dutyfinch, free tier, no key)

# search by keyword
curl "https://dutyfinch.cybermaxtools.com/api/search?q=bluetooth+speaker&limit=5"

# one code: official duty rates + Section 301 list status
curl "https://dutyfinch.cybermaxtools.com/api/hts?code=8517.13.00"

Good to know

Classification follows the General Rules of Interpretation (GRI 1-6) at the start of the schedule; GRI 1 says the heading text and notes come first.

This is general information for importers, not a customs ruling or legal advice.

Questions

Is HTS the same as HS code?

The first 6 digits are the international HS code; the US adds digits 7-10.

Who decides the final code?

The importer is responsible; CBP can issue a binding ruling if you ask.
