HS Code Lookup · Free
Find the HS code
for what you ship.
Type what the item is and you get the HS or HTS code, the Schedule B export number, the general duty rate, and the tariff path the code sits under. It reads the whole US tariff schedule, 35,791 HTS lines and 9,779 Schedule B lines, so unusual items come back with a real line too. This is the number USPS asks for on the customs block of an international label.
Results are ranked from a full-text index with a preference for the deepest ten-digit line, since that is the one the form asks for. The duty rate shown is the USITC general column, and Schedule B is matched on the six digits it shares with the HTS line.
Classification is the exporter's responsibility. When two lines look close, the one with the more specific description usually wins. A line worth over $2,500 needs an AES ITN; under that, write NO EEI 30.37(a) on the form.

Questions people ask.
- What is an HS code?
- The Harmonized System code is the six-digit product classification that customs authorities around the world share. The US extends it to ten digits, as an HTS number for imports and a Schedule B number for exports. On a USPS international label it is the field called HSTariffNumber, on the customs block.
- Which number goes on my form, HTS or Schedule B?
- Shipping out of the US you use a Schedule B number, though an HTS number is also accepted on USPS customs forms because the two share their first six digits. Importing into the US you use HTS. This tool shows both side by side, keyed on those shared six digits.
- Where does the data come from?
- The complete HTS catalog published by the US International Trade Commission and the complete Schedule B export catalog published by the Census Bureau, both loaded whole into our own database and searched with a full-text index. Duty rates come from the USITC general column, and statistical suffixes inherit the rate from the legal eight-digit line above them.
- Is there a daily limit?
- There is no daily cap. Requests are burst-limited per IP so nobody can pull the whole catalog down in one go, but filling out customs forms will never get you near that limit.
