Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh, chilled, frozen, dried, salted, in brine, smoked and other processed products, but excluding cooked or preserved products (classified under Chapter 16). This chapter is a core chapter in international trade of aquatic products, involving fishing, aquaculture, processing and other stages. Heading 0303 covers frozen fish, but excludes fish fillets and other fish meat (classified under 0304), fresh or chilled fish (0302) and frozen fish fillets (0304). This heading is subdivided by species, covering frozen whole fish, headless and gutted fish, etc., but excluding further processed fish products. The first 2 digits 03 represent Chapter 03: Fish, crustaceans, molluscs and other aquatic invertebrates. The 3rd-4th digits 03 represent heading 0303: Frozen fish (excluding fish fillets and other fish meat). The 5th-6th digits 45 represent subheading 030345: Frozen Bluefin tunas, including Atlantic bluefin tuna, Pacific bluefin tuna and Southern bluefin tuna. This subheading is further subdivided into 03034510 (farmed) and 03034590 (other), but this code 030345 is a 6-digit subheading and does not show further subdivisions. The product is frozen Bluefin tuna, which conforms to the description of heading 0303 (frozen fish) and belongs to the Bluefin tuna species, therefore classified under 030345. If it were fresh or chilled Bluefin tuna, it would be classified under 0302; if it were frozen fillets, it would be classified under 0304; if it were smoked or cooked, it would be classified under Chapter 16.

❓ FAQ
How to query the tax rate for HS code 030345? You can check the most-favored-nation rate, agreement rate, etc. of the corresponding importing country by entering HS code 030345 on the official website of the General Administration of Customs, the International Trade Single Window, or professional tariff query tools. Note that tax rates may be adjusted with policy changes; it is recommended to refer to the latest official data. How to distinguish frozen Bluefin tuna from other frozen tuna? Mainly based on species: Bluefin tuna (Thunnus thynnus, etc.) is classified under 030345, while other tunas such as yellowfin (Thunnus albacares) are classified under 030349. When declaring, the Latin scientific name must be provided, and customs may require a species identification certificate. Are there differences in codes for farmed and wild Bluefin tuna? Under the 6-digit subheading 030345, there is no subdivision, but some countries may distinguish farmed (e.g., 03034510) and wild (e.g., 03034590) at the 8-10 digit level. When declaring, the capture method must be truthfully filled in for correct classification. Does headless and gutted frozen Bluefin tuna affect classification? No, as long as no further processing such as slicing or mincing has been done, it is still classified under 030345. However, if cut into fillets, it is classified under 0304. What regulatory documents are required for importing frozen Bluefin tuna? Usually, a certificate of origin, health certificate, fishing certificate (if applicable), import animal and plant quarantine permit, etc. are required. Specific requirements are subject to the importing country; it is recommended to consult customs or a professional customs broker in advance. Is Bluefin tuna regulated by CITES? Some Bluefin tuna species (such as Atlantic bluefin) are regulated under CITES Appendix I, and import/export requires a CITES permit. Other species may be regulated under Appendix II; the specific species must be confirmed. What are the consequences of incorrectly filling in the Latin scientific name during declaration? It may lead to classification errors, incorrect tax rate application, and even suspected false declaration, facing customs penalties. Be sure to fill it in accurately; refer to authoritative species databases. How does the packaging specification of frozen Bluefin tuna affect declaration? Packaging specification is one of the declaration elements and must be truthfully filled in.
