How this search works
  • Your term is matched both against the official Chinese customs tariff descriptions (translated to English) and against a large corpus of real import declarations.
  • It is also looked up in the official names of the wider tariff headings — many products, from musical instruments to medical devices, are named only at that level, not in any 10-digit description.
  • Codes are ranked so that generic catch-all headings — “other articles of plastics”, “other parts” — do not crowd out the specific code you are looking for.
  • The result list is a starting point, not a ruling. Final classification is decided by China Customs; use the import duty calculator to estimate the duty on a specific code.
