A full HS code. These six digits are what goes on a customs declaration, and they mean the same thing in every country that uses the Harmonized System.
Section I, Live Animals & Animal Products — live animals, meat, fish, dairy and other products of animal origin.
- 03 Chapter Fish and crustaceans, molluscs and other aquatic invertebrates
- 02 Heading Fish; fresh or chilled, excluding fish fillets and other fish meat of heading 0304
- 31 Subheading Fish; fresh or chilled, albacore or longfinned tunas (Thunnus alalunga), excluding fillets, fish meat of 0304, and edible fish offal of subheadings 0302.91 to 0302.99
Chapter 3 covers fish, crustaceans, molluscs and other aquatic invertebrates, whether live, fresh, chilled, frozen, dried, salted or in brine. It is one of the largest HS chapters by code count because each species and presentation (whole, fillets, live) gets its own six-digit line. Classification tip: Smoked, canned or otherwise cooked seafood preparations move out of chapter 3 and into chapter 16: only the raw or simply preserved product stays here.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.
Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.

0302.31 covers fish; fresh or chilled, albacore or longfinned tunas (thunnus alalunga), excluding fillets, fish meat of 0304, and edible fish offal of subheadings 0302.91 to 0302.99. It sits under heading 03.02 (fish; fresh or chilled, excluding fish fillets and other fish meat of heading 0304) in chapter 03, Section I of the Harmonized System.
It is the international part of it. Six digits are the same in every country that applies the Harmonized System; the importing country then extends them to eight or ten for its own tariff and statistics. Declare 0302.31 plus whatever national digits the destination’s tariff schedule adds to it.
The General Rules of Interpretation, read together with the notes to Section I and to chapter 03. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.
A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
