Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh, chilled, frozen, dried, salted, smoked and other processed products. This chapter is the core chapter for aquatic animal products, involving multiple stages such as fishing, aquaculture, processing and trade. When classifying for customs, key factors to focus on include species, preservation state, degree of processing, etc., while also noting the distinction from other chapters (such as Chapter 16 prepared products). Heading 0302 covers fresh or chilled fish, but excludes fish fillets and other fish meat (0304), and whole or cut frozen fish (0303). Under this heading, it is subdivided by species, including salmon, cod, tilapia, tuna, etc. Fresh or chilled means not frozen, usually at a temperature of around 0°C, maintaining the fresh state of the fish, suitable for short-term storage and transport. Code 030250 has 6 digits: the first 2 digits 03 represent Chapter 3 'Fish, crustaceans, molluscs and other aquatic invertebrates'; digits 3-4, 02, represent the heading 'Fresh or chilled fish, excluding fish fillets and other fish meat of 0304'; digits 5-6, 50, represent the subheading 'Cod (Gadus morhua, Gadus ogac, Gadus macrocephalus)'. Therefore, 030250 specifically refers to fresh or chilled cod, including species such as Atlantic cod, Greenland cod, Pacific cod, etc. This commodity is fresh or chilled cod, not frozen, dried, salted or smoked, and not cut into fillets or minced meat, so it is classified under 0302 rather than 0303 (frozen fish), 0304 (fish fillets), 0305 (dried, salted, smoked fish). At the same time, the cod species is specific, distinguishing it from other fresh or chilled fish (such as 0302.1 salmon, 0302.3 tilapia, etc.).

Product Name: Fill in the specific species name, such as 'fresh cod' or 'chilled cod', avoiding the generic term 'fresh fish'. Latin Scientific Name: Fill in the Latin scientific name of the cod, such as Gadus morhua, Gadus macrocephalus, etc., to ensure species accuracy. Preservation State: Clearly state 'fresh' or 'chilled', and indicate temperature conditions (e.g., 0-4°C) to distinguish from frozen. Processing Method: Indicate whether headed, gutted, boned, etc., but not sliced or minced. Specification: Fill in the weight per fish or size range, such as '200-500g/piece', for statistics and inspection. Packaging Method: Indicate the packaging type, such as 'boxed, ice-chilled', and note the quantity per box. Brand: If there is a brand, fill in the brand name; if no brand, fill in 'none'. Origin: Fill in the country/region of fishing or farming, such as 'Norway', 'Russia', etc. Customs declaration example: Product Name: Fresh Cod Latin Scientific Name: Gadus morhua Preservation State: Chilled (0-2°C) Processing Method: Headed, gutted, not boned Specification: 300-500g/piece Packaging Method: Boxed, 20kg per box, ice-chilled Brand: None Origin: Norway HS Code: 03025000 Mistakenly classifying chilled cod under 0303 (frozen cod), leading to incorrect tax rates and regulatory conditions. Not providing the Latin scientific name, unable to confirm the species, may be classified under other fresh fish subheadings. Mistakenly declaring boned cod fillets as whole cod, which should actually be classified under 0304.

Core basis for classification: 1) The commodity is fresh or chilled, not frozen; 2) The species is cod (Gadus genus); 3) Not processed into fillets, minced meat or other 0304 products; 4) Not subjected to drying, salting, smoking or other 0305 processing. Also refer to the 'Import and Export Tariff' and customs classification decisions to ensure species and state accuracy. 0303.63 Frozen cod: 0303 is frozen fish, temperature below -18°C, while 0302 is fresh or chilled, usually around 0°C. The core difference is the preservation state. 0304.71 Fresh or chilled cod fillets: 0304 is fish fillets and other fish meat, even if fresh or chilled, but sliced or minced, while 0302 is whole or headed and gutted but not sliced fish. 0305.51 Dried cod: 0305 is dried, salted, smoked fish, with a higher degree of processing, while 0302 is only fresh or chilled, not subjected to these treatments. 0302.49 Other fresh or chilled fish: 0302.49 is other fresh or chilled fish not elsewhere specified; if the cod species is not within the scope of 0302.50, it is classified under this subheading. Confirm the commodity state is fresh or chilled, not frozen. Confirm the species is cod (Gadus genus), not Alaska pollock or others. Confirm not sliced, not minced, kept whole or headed and gutted. Confirm not subjected to drying, salting, smoking or other processing. Check that the Latin scientific name is consistent with the subheading notes of the tariff.

How to query the HS code for fresh cod? You can check through the General Administration of Customs website, HS code query platforms, or consult a customs broker. Enter the keyword 'fresh cod' or the Latin scientific name, and the system will recommend 030250. Note the distinction between chilled and frozen: chilled is classified under 0302, frozen under 0303. What is the difference between the codes for fresh cod and frozen cod? Fresh or chilled cod is classified under 030250, frozen cod under 030363. The tax rates and regulatory conditions may differ, and frozen requires cold chain certification. Incorrect classification may cause customs clearance delays. Which code should cod fillets be classified under? Fresh or chilled cod fillets are classified under 030471, frozen cod fillets under 030472. If further processed or seasoned, they may be classified under Chapter 16. Note the difference between fillets and whole fish. Is the Latin scientific name required for declaration? Yes, the Latin scientific name is key to determining the species, especially for cod, as different species may affect classification. If unable to provide, customs may require inspection and identification, delaying clearance. What regulatory conditions are required for importing fresh cod? Usually requires animal and plant quarantine permits, certificate of origin, health certificate, etc. Specific requirements depend on the exporting country and customs. It is recommended to check in advance the 'List of Overseas Production Enterprises Registered for Imported Food' and quarantine approval. If the cod is headed and gutted, will the code change? Headed and gutted but not sliced cod is still classified under 030250, but the processing method must be indicated in the declaration elements. If cut into fillets, it is classified under 0304. What is the difference between 030250 and 030259? 030250 specifically refers to cod (Gadus genus), while 030259 is other fresh or chilled fish, including fish not elsewhere specified. If the species is not cod, it is classified under 030259. How to declare fresh cod sold through cross-border e-commerce? Cross-border e-commerce usually adopts bonded import or direct purchase import models, and the HS code must be declared according to the actual state. Fresh cod, due to its short shelf life, is mostly imported through direct purchase, requiring quarantine certificates and Chinese labels.
