United StatesCustoms — Frequently Asked Questions
What is the difference between an HS code and an HTS code?
An HS code is the international 6-digit code maintained by the World Customs Organization. An HTS code is the US-specific 10-digit extension — the first 6 digits are the same as the HS code, and the remaining 4 digits are specific to the US tariff schedule administered by the USITC.
What is a Schedule B code and how does it differ from an HTS code?
Schedule B codes are used for US exports and are administered by the US Census Bureau. HTS codes are used for US imports. Both share the same first 6 digits as the international HS code, but the last 4 digits may differ. Use Schedule B when filing Electronic Export Information (EEI) through AES.
Where can I find the duty rate for my HTS code?
The official USITC HTS search at hts.usitc.gov shows duty rates for every 10-digit HTS code. The tool above finds your 6-digit HS subheading — use it on the USITC site to find the full 10-digit US code and applicable duty rate.
Do HS codes change with US tariff actions?
The 6-digit HS codes are set by the WCO and are stable until the next revision (2027). However, US duty rates applied to those codes can change independently through executive tariff actions, Section 301 tariffs, and trade agreement modifications. Always verify current rates at hts.usitc.gov.
