Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh, chilled, frozen, dried, salted, smoked and other processed products. However, this chapter does not include: products further processed by cooking, frying, etc. (classified under Chapter 16), ornamental fish (heading 0301), and certain aquatic mammals (heading 0106). This chapter is the core chapter for international trade in aquatic products. Heading 0303 covers frozen fish, but does not include frozen fish fillets and other fish meat (classified under 0304), frozen fish livers and roes (classified under specific subheadings within 0303). This heading includes whole fish, headed and gutted fish, and frozen fish cut into pieces but not further processed. Main species include tuna, salmon, cod, etc. First 2 digits 03: represents Chapter 3, i.e., fish, crustaceans, molluscs and other aquatic invertebrates. Digits 3-4, 03: represents heading 0303, i.e., frozen fish (excluding fillets and fish meat). Digits 5-6, 46: represents subheading 030346, i.e., Southern Bluefin Tuna. The complete code 030346 indicates frozen Southern Bluefin Tuna, whether whole, headed and gutted, or cut, but not further processed. This commodity is frozen Southern Bluefin Tuna, which meets the basic characteristics of heading 0303 (frozen fish), and the species is specifically identified as Southern Bluefin Tuna, therefore classified under subheading 030346. It is not classified under other subheadings of 0303 (such as 030341-030345 for other tunas), nor under 0304 (frozen fish fillets), because it is not sliced.

🎯 Classification Logic
Core basis for classification: 1) The commodity must be in frozen state, meeting heading 0303; 2) The species must be Southern Bluefin Tuna (Thunnus maccoyii), meeting subheading 030346; 3) It must not have undergone further processing such as slicing or mincing, otherwise classified under 0304; 4) Supporting documents such as Latin scientific name and fishing area must be provided. 030341 Frozen Albacore Tuna: Different species; Albacore Tuna (Thunnus alalunga) differs from Southern Bluefin Tuna in morphology and distribution. 030342 Frozen Yellowfin Tuna: Yellowfin Tuna (Thunnus albacares) has yellow fins, clearly different from Southern Bluefin Tuna. 030345 Frozen Atlantic Bluefin Tuna: Atlantic Bluefin Tuna (Thunnus thynnus) and Southern Bluefin Tuna have different distribution sea areas and must be distinguished by Latin scientific name. 0304 Frozen Fish Fillets and Other Fish Meat: 0304 is sliced or minced fish meat, while 030346 is whole or headed and gutted frozen fish. Is the Latin scientific name confirmed as Thunnus maccoyii? Is it frozen rather than fresh or chilled? Has it not undergone processing such as slicing or mincing? Is the fishing area certificate provided? Have the latest customs classification decisions been checked?
