Why classification and valuation need structured review

Customs compliance often turns on two core questions: how the goods are classified and how the assessable value is determined. Classification affects the rate of duty, exemption eligibility, import restrictions, documentation and sometimes the entire commercial model. Valuation affects the duty base and may involve related-party imports, assists, royalties, freight, insurance and post-import payments.

A review should start with the product description, technical literature, composition, function, end use and commercial invoice. The tariff heading should be supported by the General Rules for Interpretation, section notes, chapter notes and any applicable explanatory material. A superficial description such as “parts”, “accessories” or “industrial item” is rarely enough.

Document checklist

  • Commercial invoice, packing list, bill of entry and purchase contract.
  • Product catalogue, technical specification and composition details.
  • Import licence or restriction analysis, if applicable.
  • Exemption notification conditions and end-use requirements.
  • Relationship and valuation documents for related-party imports.

Customs positions should be reviewed carefully because disputes may affect duty, interest, penalty, confiscation exposure and future import clearances.

Client documents, notices and case facts should be shared only through secure, verified channels. Public pages remain educational and non-confidential.
