HS Code 0303Fish; frozen, excluding fish fillets and other fish meat of heading 0304
44 six-digit codes · Heading 3 of 9 in Chapter 03 · World Customs Organization Harmonized System
HS code 0303 is the frozen fish heading, for fish that has been frozen but not cut into fillets. This page groups its codes by fish type and shows how to tell it apart from the nearby headings.
Heading 0303 is finely cut: 44 six-digit codes, 030311 to 030399, all of them under “Fish; frozen, excluding fish fillets and other fish meat of heading 0304”. At that depth it is the exact wording of the code, not of the heading, that settles a classification. The heading is number 3 of 9 in Chapter 03, Fish and crustaceans, molluscs and other aquatic invertebrates, which runs to 225 six-digit codes in all.

What HS code 0303 covers
Heading 0303 is where customs places frozen whole fish and frozen cuts that are not fillets. It is part of Section I, Live Animals; Animal Products, and it sits inside Chapter 03 with the other fish, crustacean and mollusc headings.
Some frozen fish parts are here too, such as livers, roes, fins and heads. They have their own codes at the end of the list.
The fish must be frozen, and it must not be a fillet.
HS 0303 codes by fish type
Every species code below leaves out fillets, 0304 fish meat and the offal codes 030391 to 030399. That note is stated once here so the list stays short.
- Freshwater and farmed fish (030323 to 030326, 030329): tilapia, catfish, carp, eels, Nile perch and snakeheads.
- Herring, sardines and mackerel (030351, 030353 to 030357, 030359): herring, sardines and sprats, mackerel, jack and horse mackerel, cobia, swordfish and a catch-all code.
- Cod family (030363 to 030369): cod, haddock, coalfish, hake, Alaska pollock, blue whiting and related fish.
- Sharks, rays, toothfish and seabass (030381 to 030384, 030389): dogfish and other sharks, rays and skates, toothfish, seabass, and a catch-all code.
0303 vs 0302, 0304 and 0305: picking the right heading
The state of the product decides the heading, not the fish. The same salmon can land in different headings depending on how it is shipped.
Live fish go to 0301. Flours, meals and pellets of fish for people to eat are in 0309. Crustaceans are in 0306 and molluscs are in 0307.
Inside the fresh-or-frozen question, the cut matters. A frozen tuna fillet is not, and a fresh whole tuna is not either.
If you are unsure, try the HS code classifier, and read the exact subheading wording before you file.
How to read the code 0303.42
An HS code is built in layers. Take 030342 as an example. The first two digits, 03, are the chapter for fish, crustaceans, molluscs and other aquatic invertebrates. The first four digits, 0303, are the heading for frozen fish that is not filleted. All six digits point to one product: frozen yellowfin tuna.
Countries may add their own digits for national tariffs. So the frozen fish hs code on a customs form can be longer than six digits.
