Customs & Tariff Classification

Tariff Classification

Also known as: Classification, HS Classification

Tariff classification is the disciplined process of assigning an imported product its correct code within the Harmonized System and the national tariff schedule, following the legally binding General Rules of Interpretation, the section and chapter notes, and, where helpful, the explanatory notes and prior rulings. Classification governs the duty rate, the applicability of trade-remedy measures and quotas, and whether partner-agency requirements attach, so an error can mean overpayment, underpayment with penalties, or a shipment held at the border. Skilled classification weighs a product's essential character, composition, function, and stage of manufacture against the schedule's precise legal language.

Classification is an argument, not a lookup. It is built from the General Rules of Interpretation, then the section and chapter notes, then the Explanatory Notes, in that order — and the test of whether you have one is simple. Ask why your code is right. If the answer does not come back in those terms, what you have is a number on a filing rather than a position anyone could defend.

Where it matters for compliance

  • Apply the GRIs in sequence. Reaching GRI 3 without exhausting GRI 1 is the commonest error in the entries we see.
  • Section and chapter notes are binding and frequently decide a case that the heading text alone leaves open.
