HTS code lookup and validator
Check a US tariff number against the current Harmonized Tariff Schedule, or search by product description.
How US tariff numbers work
The first six digits are the international Harmonized System (HS) code, the same in every country. The United States adds two digits for the tariff rate line (8 digits) and two statistical digits (10 digits). A US entry line in ACE needs the full 10-digit number, and many lines also need a quantity in the unit the schedule names — kilograms, pieces (“No.”), dozens or square meters.
Why invoice codes are often wrong for US entries
Exporters print their own country's codes. A German invoice shows an EU CN code such as 8466.10.00, which shares only the first six digits with the US number. FreightProof flags these lines and suggests the matching 10-digit HTSUS numbers.
Additional duties
The general rate is not the whole story. Goods made in China often carry Section 301 duties under heading 9903.88, steel and aluminum articles may carry Section 232 duties, and some products are covered by antidumping or countervailing duty orders. Always check Chapter 99 and CBP's AD/CVD cases.

Check the whole shipment, not one number
FreightProof reads the invoice, packing list and bill of lading together, validates every HTS number and container, builds the MIDs and flags what does not match — in about two minutes.
