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.

Other headings in chapter 03
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.

Track a shipment03.04 FAQ
Heading 03.04 covers fish fillets and other fish meat (whether or not minced); fresh, chilled or frozen. It is part of chapter 03 (fish and crustaceans, molluscs and other aquatic invertebrates), and it is subdivided into 48 six-digit subheadings — the level you actually declare.
Pick one of the 48 subheadings below. Those six digits are what customs recognises internationally; the importing country may extend them to eight or ten in its own tariff schedule.
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.
