How to read an HTS code

A US HTS code is 10 digits, read in layers. Take 6109.10.00.04 — a plain white cotton T-shirt:

  • 61 — Chapter (knitted apparel)
  • 6109 — Heading (T-shirts, singlets and similar garments)
  • 6109.10 — Subheading (of cotton) — the international 6-digit HS code
  • 6109.10.00 — US tariff line — this is where the duty rate (16.5%) is set
  • 6109.10.00.04 — Statistical suffix (all-white, short-sleeve breakout) for trade data

The first six digits are shared worldwide; the last four are US-specific. New to the terminology? The tariff glossary defines HTS, HS, Chapter 99, and the 2026 measures in plain English.

Frequently Asked Questions

What is an HTS code?
An HTS (Harmonized Tariff Schedule) code is the number US Customs uses to classify an imported product and set its duty rate. Every product entering the US must be declared under an HTS code; that code — combined with the country of origin — determines what you owe.
How many digits is a US HTS code?
Ten. The first 6 digits are the international HS (Harmonized System) code shared by ~200 countries; digits 7-8 are the US tariff subheading that sets the duty rate; digits 9-10 are a statistical suffix for trade data. The duty rate is generally set at the 8-digit level.
Is the HTS code the same as the HS code?
The first 6 digits are identical — that's the global HS code. The US extends it to 10 digits (the HTS) for its own duty and statistical detail. So every HTS code contains an HS code, but not vice versa.
Where do these duty rates come from?
The rates here are a curated static snapshot of the general (MFN / column-1) duty rates in the 2026 US Harmonized Tariff Schedule — 13,776 rate-bearing lines compiled from USITC and last verified 2026-10-09. This is not a live USITC feed. "Free" means a 0% base rate. Confirm a binding rate at https://hts.usitc.gov/.
The rate shown is lower than what I was actually billed — why?
The HTS general rate is only the base. In 2026 several layers stack on top depending on origin: Section 301 tariffs on Chinese goods, Section 232 on steel/aluminum/copper (and heading-specific auto, drone, and semiconductor 232), the Section 301 forced-labor tariff (10% or 12.5% — it replaced the expired Section 122 rate on July 24, 2026), and any AD/CVD orders. Couriers (UPS/FedEx/DHL) also add their own brokerage fees. Run your code and country through the tariff calculator for the fully stacked landed number.
How do I find the exact HTS code for my product?
Search by a plain-language product word (e.g. "cotton t-shirt", "lithium battery", "office chair") and scan the matching lines, or type a partial code like 8471 to drill down. Classification can be nuanced — when the duty or compliance stakes are high, confirm with a licensed customs broker or a CBP binding ruling.
