Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh or chilled, frozen, dried, salted, smoked and other preservation methods. This chapter is a core chapter in international trade of aquatic products, involving fishing, aquaculture, processing and other stages. Classification requires focus on species, preservation state and degree of processing. Heading 0303 specifically covers frozen fish, but excludes fish fillets and other fish meat (classified under 0304). It includes whole fish, headless, gutted, cut into pieces and other frozen fish, covering both marine and freshwater fish. Turbot, as a cold-water marine fish, if its frozen product does not exceed simple freezing treatment, is classified under this heading. The first 2 digits 03 represent Chapter 03 'Fish, crustaceans, molluscs and other aquatic invertebrates'. Digits 3-4, 03, indicate heading 0303 'Frozen fish, excluding fish fillets and other fish meat of heading 0304'. Digits 5-6, 34, are the subheading specifically for 'Turbot (Psetta maxima)', i.e., frozen turbot. This subheading is a species-specific subdivision, reflecting the HS's refined management of high economic value fish. The product is frozen turbot whole fish or simply processed, not smoked, dried, salted or further processed, and not fillets or fish meat, therefore classified under 0303 rather than 0304 (fillets), 0305 (dried, salted or smoked fish) or 0302 (fresh or chilled fish). Meanwhile, turbot has an independent subheading 030334, so it is not classified under other frozen fish subheadings.

Product name (Chinese and foreign language): The standard Chinese and English name of the declared commodity shall use the normative name recognized by customs, such as 'frozen turbot' or 'frozen turbot'. Latin scientific name: The Latin scientific name of the species must be filled in. Turbot is Psetta maxima (or Scophthalmus maximus), ensuring correspondence with the subheading. Production or preservation method: Detailed description of the freezing method, such as 'whole frozen', 'headless and gutted frozen', 'block frozen', etc., and indicate whether other processing has been carried out. State (whole/headless/cut into pieces, etc.): Clarify the physical state of the commodity, such as 'whole', 'headless and gutted', 'cut into pieces', etc., which affects whether it is classified under 0303 or 0304. Packaging specifications: Fill in the specifications of inner and outer packaging, such as '10kg/carton, inner plastic bag and outer carton', to facilitate customs inspection. Brand type: Select 'no brand', 'domestic independent brand', 'foreign brand (OEM)', etc., and truthfully declare the brand status. Fishing or aquaculture method: Indicate 'wild caught' or 'farmed', as some countries have quota or certification requirements. Product name: Frozen turbot; Latin scientific name: Psetta maxima; Production and preservation method: headless and gutted, whole frozen; State: whole; Packaging specifications: 10kg/carton, inner plastic bag and outer carton; Brand type: no brand; Fishing method: farmed. Misclassifying headless and gutted but not sliced frozen turbot under 0304 (fillets), when it actually remains under 0303. Incorrect or missing Latin scientific name, resulting in inability to correspond to subheading 030334. Failure to distinguish frozen from fresh or chilled, mistakenly using heading 0302, causing classification errors.

Core classification basis: 1) The commodity must be in frozen state, conforming to heading 0303 description; 2) The species must be turbot (Psetta maxima), corresponding to subheading 030334; 3) The degree of processing is limited to simple treatments such as freezing, heading, gutting, cutting into pieces, etc., not made into fillets, surimi or subjected to smoking, salting, etc.; 4) If it is fillets or fish meat, it is classified under 0304; if fresh or chilled, under 0302. 0302.34 Fresh or chilled turbot: Different preservation state: 0302 is fresh or chilled, 0303 is frozen. Temperature control is the key distinguishing point. 0304.29 Other frozen fish fillets: Different degree of processing: 0304 is fillets or fish meat, already sliced; 0303 is whole fish or simply cut, not filleted. 0303.89 Other frozen fish: Different species: 0303.89 is frozen fish not elsewhere specified; turbot has a dedicated subheading 030334, which takes priority. 0305.49 Other frozen smoked fish: Different processing method: 0305 is smoked then frozen, 0303 is only frozen, not smoked. Confirm the commodity is in frozen state, not fresh or chilled. Check whether the Latin scientific name is Psetta maxima. Check whether it has been sliced or further processed, to avoid mistakenly entering 0304. Confirm it has not been smoked, salted or dried. Verify whether packaging and labels are consistent with the declaration.

Are frozen turbot and frozen turbot the same HS code? Yes, turbot is the common name for turbot, scientific name Psetta maxima, and in frozen state it is classified under 030334. However, when declaring, the normative name 'turbot' must be used, and the Latin scientific name filled in, to avoid classification disputes caused by common names. If frozen turbot is headless and gutted but not sliced, which code should it be classified under? It is still classified under 030334. 0303 includes whole fish, headless, gutted, cut into pieces and other simple treatments. As long as it is not made into fillets or fish meat, it is not classified under 0304. If sliced, it must be classified under 0304.29. How to query the tariff rate for 030334? The latest tariff rate can be queried through the General Administration of Customs website, China International Trade Single Window or the 'Import and Export Tariff of the People's Republic of China'. Tariff rates may change due to trade agreements and annual adjustments; it is recommended to refer to the latest official publication. What are the consequences of writing the Latin scientific name incorrectly during declaration? It may lead to classification errors, affecting tariff collection and regulatory conditions, and may even be deemed as false declaration, facing administrative penalties. Be sure to check authoritative taxonomic references to ensure the scientific name is accurate. What regulatory documents are required for importing frozen turbot? Usually, an official quarantine certificate from the exporting country, certificate of origin, import animal and plant quarantine permit, etc. are required. The specific requirements are subject to the latest announcement of the General Administration of Customs; it is recommended to consult the local customs in advance. How to distinguish 030334 from 030389? 030334 specifically refers to frozen turbot, 030389 is other frozen fish. If the species is turbot, it must be classified under 030334, and cannot be mistakenly classified under 030389 due to not being listed. What code applies to cross-border e-commerce retail import of frozen turbot? 030334 also applies, but it must comply with the cross-border e-commerce retail import commodity list and regulatory requirements. Pay attention to personal quota, inspection and quarantine regulations, and declare truthfully. If frozen turbot is salted and then frozen, where should it be classified? Fish that is salted and then frozen should be classified under 0305 (dried, salted or brined fish; smoked fish). 0303 only applies to frozen fish that has not been salted, smoked or otherwise processed.
