What is an HTS code?
The Harmonized Tariff Schedule (HTS) is the US version of the international HS nomenclature. Every imported product needs a 10-digit HTS number for customs entry. That code determines your Column 1 general duty rate, eligibility for free-trade agreement rates, and whether ADD/CVD or Section 301 tariffs apply.
This tool lets you search the Harmonized Tariff Schedule by number or plain-English product description — a faster, cleaner way to look up a harmonized tariff code than paging through the official USITC site. Results pull the same Column 1, special-program, and Column 2 duty rates straight from the USITC HTS export.

FAQ
HTS code questions
What is an HTS code?
An HTS (Harmonized Tariff Schedule) code is a 10-digit number used by US Customs to classify imported goods. The first six digits align with the international HS code; digits 7–10 are US-specific statistical suffixes that determine your duty rate.
How do I find my HTS code?
Start with your product category (e.g. footwear, electronics), search by keywords or browse by chapter, then narrow to the most specific 10-digit code that describes your product. Use our free description search or optional AI refinement for guidance.
Is this HTS lookup free?
Yes. Code search, chapter browse, and product-description matching are 100% free with no login required. Optional AI classification uses credits for logged-in users.

HTS vs HS — what's the difference?
HS (Harmonized System) is the global 6-digit classification used by most countries. HTS (Harmonized Tariff Schedule) extends HS to 10 digits for US imports. Schedule B is the export equivalent administered by the US Census Bureau.
