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, 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.
How do I look up an HTS or tariff number?
Type the number at any length (e.g. 6403 or 6403.99.90) into the search box to jump straight to matching entries, or enter product keywords to find the right 10-digit tariff number. Every result shows its Column 1 duty rate and chapter.
Is this the same as the USITC HTS search tool?
It draws on the same data. We import the official Harmonized Tariff Schedule export from the USITC (hts.usitc.gov) — the same source behind the government HTS search — and add faster keyword search, chapter browsing, and a one-click link to landed cost.
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.
How accurate is this tool?
Duty rates and descriptions come directly from the official USITC HTS export. Classification guidance is not legal advice — always verify with US Customs or a licensed customs broker before filing.
HTS vs HS — what's the difference?
HS is the global 6-digit classification used by most countries. HTS extends HS to 10 digits for US imports. Schedule B is the export equivalent administered by the US Census Bureau.
Where does the data come from?
We import the official USITC Harmonized Tariff Schedule export from hts.usitc.gov — the same source used by US Customs.
