Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates. This chapter includes live, fresh, chilled, frozen, dried, salted, in brine, smoked and other aquatic products, as well as similar processed products of crustaceans and molluscs. This chapter does not include: mammals (such as whales and dolphins), reptiles, frogs, etc. (classified under Chapter 01 or Chapter 02); animal products other than aquatic invertebrates (such as pearls and coral, classified under Chapter 05 or Chapter 71); and ready-to-eat aquatic products that have undergone deep processing such as cooking or frying (classified under Chapter 16). Heading 0302 covers fresh or chilled fish, but does not include fish fillets and other fish meat (whether or not minced, classified under 0304), nor frozen fish (classified under 0303). This heading includes whole fish, fish that are headed and gutted but not further processed, as well as fish livers, roes and milt for human consumption. Fresh fish refers to fish that have not been frozen or preserved and generally retain their original form; chilled fish refers to fish whose body temperature has been reduced to near 0°C by ice or refrigeration equipment but has not been frozen. Fish under this heading must remain fresh or chilled and must not have undergone any salting, smoking or cooking treatment. Code 030271 has 6 digits: the first 2 digits "03" represent Chapter 03 (Fish, crustaceans, molluscs and other aquatic invertebrates); digits 3-4 "02" represent heading 0302 (Fresh or chilled fish, excluding fish fillets and other fish meat); digits 5-6 "71" represent subheading 030271 (Fresh or chilled tilapia). Among these, the 5th digit "7" indicates the sequence of subheadings under 0302 divided by fish species, and the 6th digit "1" further specifies tilapia. Therefore, 030271 specifically refers to fresh or chilled tilapia, whether or not headed and gutted, as long as it has not undergone freezing, salting, smoking or cooking processing, it is classified under this code. Tilapia is a fresh or chilled whole fish that has not been frozen or deeply processed, so it should be classified under 0302 rather than 0303 (frozen fish) or 0304 (fish fillets). The difference from other subheadings under 0302 (such as 030231 tuna, 030241 herring) lies in the different fish species; tilapia corresponds to subheading 030271. If tilapia has been frozen, it is classified under 0303; if only filleted, it is classified under 0304; if salted, smoked or cooked, it is classified under 0305 or 1604.

Product Name: Fill in the Chinese and foreign language names of the commodity, which should be specific to the fish species, such as "fresh tilapia" or "chilled tilapia", avoiding the general term "fresh fish". State: Indicate "fresh" or "chilled". Fresh means not subjected to cooling treatment or only kept fresh with ice; chilled means temperature controlled at around 0°C but not frozen. Processing Method: State whether headed, gutted, scaled, etc., such as "whole, not gutted" or "headed and gutted". Latin Scientific Name: The Latin scientific name of the tilapia genus, such as Oreochromis spp., which helps customs accurately identify the fish species. Specifications: Describe by weight per fish or body length, such as "200-300g/piece", for statistical and document review purposes. Packaging Method: Such as "boxed, 10 kg per box", indicating outer packaging and net weight. Brand: If there is a brand, declare the brand name; if no brand, fill in "none". Country of Origin: Fill in the country (region) of origin of the fish, such as "China", "Vietnam", etc. Product Name: Fresh Tilapia; State: Chilled; Processing Method: Whole, gutted, not headed; Latin Scientific Name: Oreochromis niloticus; Specifications: 300-500g/piece; Packaging Method: Boxed, net weight 10 kg per box; Brand: None; Country of Origin: China. Mistaking chilled tilapia for 0303 (frozen fish), resulting in incorrect tax rates and regulatory conditions. Failing to declare the Latin scientific name, which may affect customs' identification of the fish species and lead to classification disputes. Unclear description of processing method, such as "gutted" without specifying whether headed, may be classified under 0304 (fish fillets).

Core classification criteria: 1) The commodity state must be fresh or chilled, not frozen; 2) It must be whole fish, even if headed and gutted, as long as it is not cut into fillets or minced meat, it is still classified under 0302; 3) The fish species must be tilapia (Oreochromis spp., etc.), determined by Latin scientific name; 4) The processing method must not exceed the scope of fresh or chilled, and must not involve salting, smoking, cooking, etc. If the above conditions are met, it is classified under 030271. Otherwise, it is classified under 0303, 0304, 0305 or 1604 according to the corresponding processing state. 030323 Frozen Tilapia: 030323 is frozen tilapia, which has undergone freezing treatment at temperatures below 0°C; while 030271 is fresh or chilled, not frozen. The core difference lies in whether it has been frozen. 030431 Fresh or Chilled Tilapia Fillets: 030431 is fresh or chilled tilapia fillets, i.e., only the fish meat is sliced, removing bones, skin, etc.; while 030271 is whole fish, even if headed and gutted, the fish body remains intact. 030539 Other Dried, Salted or In Brine Tilapia: 030539 is tilapia that has been dried, salted or in brine, with processing methods beyond the scope of fresh or chilled; while 030271 is limited to fresh or chilled, without any preservation treatment. 160419 Other Prepared or Preserved Tilapia: 160419 is tilapia that has undergone deep processing such as cooking, frying, canning, etc., which has changed its essential characteristics; while 030271 is a primary aquatic product, only fresh or chilled. Confirm the commodity state is fresh or chilled, not frozen. Confirm the commodity is whole fish, not fillets or minced meat. Confirm the fish species is tilapia, provide the Latin scientific name. Confirm it has not undergone salting, smoking, cooking or other processing. Check whether packaging and specifications are consistent with the declaration.

How to distinguish the HS code for fresh tilapia and frozen tilapia? Fresh or chilled tilapia is classified under 030271, and frozen tilapia is classified under 030323. The key is whether the fish body has undergone freezing treatment: fresh or chilled fish body temperature has not dropped below freezing point and remains soft; frozen fish is hard, with core temperature below 0°C. When declaring, indicate the state and ensure consistency with the actual goods. Which code should headed and gutted tilapia be classified under? If only headed and gutted, but the fish body remains intact (not sliced), and the state is fresh or chilled, it is still classified under 030271. If further cut into fillets, it is classified under 030431 (fresh or chilled tilapia fillets). Note: headed and gutted does not equal fillets; classification is based on whether the whole fish form is maintained. Is it mandatory to provide the Latin scientific name of tilapia in the declaration? Yes, it is recommended to provide the accurate Latin scientific name, such as Oreochromis niloticus, Oreochromis mossambicus, etc. Customs may confirm the fish species based on the scientific name to avoid confusion with similar species. If unable to provide, it may lead to classification disputes or delays in customs clearance. What are the differences in regulatory conditions between chilled tilapia and frozen tilapia? Regulatory conditions vary by country/region; generally, frozen aquatic products may involve more inspection and quarantine requirements. Specifically, consult the latest "Import and Export Tariff" and customs announcements. It is recommended to check the regulatory conditions for this code through the General Administration of Customs website or the Single Window to ensure compliance. If tilapia is salted but not frozen, which code should it be classified under? Salted tilapia exceeds the scope of fresh or chilled and should be classified under 030539 (other dried, salted or in brine tilapia). If further cooked after salting, it is classified under 160419. Note: salting includes dry salting and brine salting, neither of which belongs to 030271. How to declare the HS code for cross-border e-commerce sales of fresh tilapia? For cross-border e-commerce retail export of fresh tilapia, if it meets the fresh or chilled conditions, it is still classified under 030271. However, note: personal items and goods declarations are different; cross-border e-commerce is usually declared as goods, requiring complete declaration elements. It is recommended to consult local customs to confirm whether inspection and quarantine are required. What is the difference between 030271 and 030279? 030271 specifically refers to tilapia, while 030279 is the subheading under 0302 for other fresh or chilled fish, including other fish species not elsewhere specified. If the fish species is not tilapia and is not listed under other subheadings, it is classified under 030279. Always confirm the fish species when classifying. How to check the import tax rate and regulatory conditions for 030271? You can check through the General Administration of Customs website, China International Trade Single Window, or the "Import and Export Tariff". Tax rates may change with free trade agreements, most-favored-nation treatment, etc., and regulatory conditions (such as inspection and quarantine categories) may also be adjusted. It is recommended to rely on the latest official data or consult a professional customs broker.
