What is an HTS Code?
An HTS code (Harmonized Tariff Schedule code) is a 10-digit tariff code used by U.S. Customs and Border Protection (CBP) to classify every product imported into the United States. Also called a tariff code or HTS number, it determines the duty rate you pay, whether your product qualifies for free trade programs, and how your import is tracked statistically.
LookupHTS uses the official USITC 2026 Revision 5 data — the same source CBP uses — to deliver instant results when you look up HTS codes or tariff codes for 13,650 classifications across 98 chapters.
How to Look Up an HTS Code
- Describe your product in plain English (e.g., "cotton t-shirt", "laptop", "honey"). Material composition matters.
- Look up HTS codes on LookupHTS — our engine matches your description against the full 2026 schedule instantly.
- Review matches — check each result's general duty rate, special (FTA) rate, and Column 2 rate.
- Verify with CBP — for high-value or uncertain classifications, request a binding ruling from CBP at rulings.cbp.gov.
HTS Code FAQ
What's the difference between HTS codes and HS codes?
HS codes are the international 6-digit system maintained by the World Customs Organization (WCO) and used by 200+ countries. HTS codes are the U.S.-specific 10-digit extension — the first 6 digits match HS codes, and the last 4 digits are unique to the United States. If you're importing into the U.S., you need the HTS code.
How accurate are LookupHTS results?
LookupHTS uses the official USITC 2026 Revision 5 data — the exact same source CBP uses. The data is public domain and verified. However, HTS classification can be complex, and LookupHTS is for informational purposes only. For binding classifications on high-value shipments, request a CBP binding ruling or consult a licensed customs broker.
Is LookupHTS really free?
Yes. LookupHTS is 100% free with no login required. The USITC Harmonized Tariff Schedule is public domain government data. We maintain this tool as a free public resource for the trade community.
Are Section 301 and Section 232 tariffs included?
The duty rates shown are the base rates from the USITC schedule (General, Special, and Column 2). Additional tariffs such as Section 301 (China), Section 232 (steel/aluminum), anti-dumping duties, and countervailing duties may apply on top of these base rates. Always check the CBP website or consult a broker for your specific product and country of origin.
How often is HTS data updated?
The USITC publishes multiple revisions per year. LookupHTS reflects the 2026 Revision 5 schedule, which is the most recent version. Revisions are triggered by trade agreements, Congressional legislation, Presidential proclamations, and WCO updates.
Can I use LookupHTS for exports?
LookupHTS covers HTS codes for U.S. imports. For U.S. exports, you'll typically use Schedule B codes (also 10 digits) from the U.S. Census Bureau. However, the first 6 digits of both systems are the same international HS code, which can be useful when shipping to other countries.
