What is an HS code?

Tariffs and customs glossary · 2 primary sources

The 6-digit Harmonized System code shared by most countries' tariff schedules, maintained by the World Customs Organization.

The Harmonized Commodity Description and Coding System (HS) gives every traded product a 6-digit code. Countries that use it, including the US, EU, UK, China and Canada, then add their own digits for national rates and statistics.

That is why the first 6 digits of a US HTS code usually match the code your overseas supplier puts on the commercial invoice, while the remaining digits differ by country. The HS is revised about every five years; the HS 2022 edition is the current one at the time of writing.
