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 international trade in aquatic products, involving fishing, aquaculture, processing and other links, with commodities ranging from food to industrial uses. Within the chapter, it is subdivided by species, processing state and use, aiming to provide a unified classification basis for customs supervision, trade statistics and tariff collection. Heading 0302 covers fresh or chilled fish, but excludes fish fillets and other fish meat (0304), frozen fish (0303) and fish livers and roes (0302.91-0302.99). This heading covers whole fish, headless and gutted fish not further processed, whether or not with skin, mainly used for trade in edible fish in a fresh-keeping state, emphasizing the preservation of the original form to facilitate distinction from deeply processed products. 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, 79, are the subheading "Other freshwater fish," referring to freshwater fish species not specifically named under 0302, such as carp, catfish, tilapia, etc. This subheading is further distinguished from specifically named subheadings such as 0302.71 (tilapia) and 0302.73 (carp), ensuring a unified classification for freshwater fish not otherwise named. This commodity is fresh or chilled other freshwater fish. Because it is not listed under a specific subheading under 0302 (such as tilapia, carp, etc.), it is classified under 0302.79 "Other." If it were frozen, it should be classified under 0303; if it were fillets, under 0304; if it were sea fish, under other subheadings of 0302. This code accurately reflects the commodity's state (fresh/chilled) and species (unnamed freshwater fish).

Product name: Fill in the specific commodity name, such as "fresh carp" or "chilled catfish," which must correspond to the scientific name of the species and avoid ambiguity from common names. Latin scientific name: Provide the Latin scientific name of the species for accurate customs identification and classification, such as Cyprinus carpio. State: Indicate "fresh" or "chilled." For chilled, specify the temperature range, such as 0-4°C. Whether headed and gutted: Describe the processing method, such as "whole," "headed and gutted," or "with skin," which affects classification. Individual weight: Declare the weight range per fish (grams/fish) for statistics and price review. Origin: Fill in the specific country/region of capture or aquaculture, which affects tariffs and trade controls. Brand: If there is a brand, declare it; if none, write "none," for intellectual property protection. Customs declaration example: Product name: Fresh carp Latin scientific name: Cyprinus carpio State: Fresh Processing method: Whole, not headed or gutted Individual weight: 500-800 grams/fish Origin: China Brand: None Specification: 10 kg/box HS code: 03027900 Mistakenly declaring chilled fish as frozen fish, leading to incorrect classification under 0303. Failing to provide the Latin scientific name, making it impossible for customs to accurately determine the species. Declaring boneless fish fillets as whole fish, which should be classified under 0304.

Core classification basis: 1) The commodity must be fish (not crustaceans, etc.); 2) The state must be fresh or chilled (not frozen, dried, smoked, etc.); 3) It must be freshwater fish (not sea fish); 4) It must not be listed under a specific subheading under 0302 (such as tilapia, carp, etc.). If it is a specifically named freshwater fish, it should be classified under the corresponding subheading; if it is sea fish, under another subheading of 0302. At the same time, fish fillets (0304) and fish livers and roes (0302.91-99) must be excluded. 030271 Fresh or chilled tilapia: Tilapia has a specifically named subheading, so even if it is a freshwater fish, it is classified under 0302.71, not 0302.79. 030273 Fresh or chilled carp: Carp has a specifically named subheading and is classified under 0302.73; only other unnamed freshwater fish are classified under 0302.79. 030289 Fresh or chilled other sea fish: Sea fish and freshwater fish are distinguished; 0302.89 is sea fish, and 0302.79 is freshwater fish. 030431 Fresh or chilled tilapia fillets: Fish fillets are classified under 0304; even if fresh or chilled, they are not classified under 0302. Is it freshwater fish? Is the state fresh or chilled? Is it not listed under a specific subheading of 0302? Is it whole fish or simply headed and gutted? Is it not fillets or fish meat?

How can it be determined whether a freshwater fish is classified under 030279? First confirm that it is freshwater fish, then check whether there is a specifically named subheading under 0302 (such as tilapia, carp, etc.). If there is no specific listing, it is classified under 030279. For example, unnamed freshwater fish such as catfish and snakehead. Is there any difference in classification between fresh fish and chilled fish? There is no difference; both are classified under 0302. However, note that the chilled temperature is usually 0-4°C; if frozen, it is classified under 0303. The state must be clearly declared. If freshwater fish is headed and gutted, is it still classified under 030279? Yes, as long as it is not further processed into fillets or fish meat, heading and gutting does not affect classification, and it is still classified under 0302. But if cut into fillets, it is classified under 0304. What is the main difference between 030279 and 030289? 030279 is freshwater fish, and 030289 is sea fish. Both belong to "other" subheadings, but the aquatic environment is different. It must be determined based on the scientific name of the species. Must the Latin scientific name be provided at declaration? Yes, the Latin scientific name is an important basis for accurate customs classification, especially for "other" subheadings, and can avoid misclassification. It is recommended to provide the standard scientific name. For cross-border e-commerce sales of fresh freshwater fish, how can tariffs be checked? Tariff rates must be determined based on origin, trade agreements, etc. The latest rates can be checked through the official website of the General Administration of Customs or the CCPIT, or by consulting a professional customs broker. If the freshwater fish is a mixed species, how should it be classified? If the mixed species are all not specifically named, they may be uniformly classified under 030279. If they include specifically named species (such as tilapia), they must be classified separately or according to the main species. What are the regulatory conditions for 030279? It usually involves animal and plant quarantine, food safety, etc. The specific regulatory conditions must be checked against the latest customs regulations, such as whether an "Inbound Goods Inspection and Quarantine Certificate" is required.
