Free HS code lookup with customs tariff and declaration guidance
Enter a full HS code, a partial code, or a plain-language product name to find the matching commodity classification.
Browse the official structure from section to chapter, heading, and subheading so you can narrow a broad category down to a specific code.
Lookups surface the tariff rate and declaration elements tied to a classification, the details customs officers actually check.
The classification search works without registration; XTransfer's payment and account products are entirely optional add-ons.
