Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, and is one of the most important chapters for animal products in international trade. This chapter is hierarchically divided according to degree of processing (live, fresh, chilled, frozen, dried, salted, etc.) and species type, involving multiple stages such as fishing, aquaculture, and processing. Commodity classification requires comprehensive consideration of factors such as species, state, and processing method. Heading 0302 specifically covers fresh or chilled fish, but excludes fish fillets and other fish meat (classified under 0304). Fish under this heading must remain whole or have only undergone simple processing such as heading and gutting, and must not have undergone further processing such as smoking, cooking, or frying. Fresh or chilled state is the core characteristic, distinguishing it from frozen fish (0303) and dried or salted fish (0305). Code 030221 is a six-digit subheading: the first two digits "03" represent Chapter 03, "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 heading 0304"; digits 5-6 "21" represent the subheading "Fresh or chilled halibut". Halibut belongs to the order Pleuronectiformes and is an important commercial fish species, further subdivided by fresh or chilled state. Halibut is in a fresh or chilled state, has not been frozen, dried, salted, or smoked, and has not been processed into fillets, so it is classified under 0302 rather than 0303 (frozen fish), 0304 (fish fillets), or 0305 (dried or salted fish). At the same time, halibut belongs to the order Pleuronectiformes and must be distinguished from other flatfish under 0302 (such as 0302.22); 030221 specifically refers to halibut.

Product name: The specific name of the declared commodity should use the standard Chinese name "Fresh or chilled halibut", and the English name "Fresh or chilled halibut" may be added. State: Clearly declare as "fresh" or "chilled". Chilled temperature is usually 0-4°C, and temperature records or explanations must be provided. Latin scientific name: Provide the Latin scientific name of halibut, such as Hippoglossus hippoglossus (Atlantic halibut) or Hippoglossus stenolepis (Pacific halibut). Processing method: Indicate whether headed, gutted, finned, etc., such as "whole, not headed or gutted" or "headed and gutted". Specifications: Declare the weight or size range of each fish, such as "2-5 kg each", which helps customs valuation and statistics. Packaging method: Indicate the packaging type, such as "boxed, 20 kg per box, layered with ice for preservation". Brand: If there is a brand, declare the brand name; if there is no brand, declare "none". Production date: Declare the fishing or processing date in YYYY-MM-DD format. Product name: Fresh or chilled halibut; State: Chilled; Latin scientific name: Hippoglossus hippoglossus; Processing method: Whole, not headed or gutted; Specifications: 3-6 kg each; Packaging method: Boxed, 20 kg per box, layered with ice for preservation; Brand: None; Production date: 2025-03-15. Misclassifying chilled halibut under 0303 (frozen fish), resulting in differences in tax rates and regulatory conditions. Failing to provide the Latin scientific name, making it impossible to prove the species, which may lead customs to question the classification. Describing the processing method as "fillets", which should be classified under 0304 rather than 0302.

The core basis for classification is the Import and Export Tariff and the Harmonized Commodity Description and Coding System. Halibut belongs to the order Pleuronectiformes, is in a fresh or chilled state, and has not been processed into fillets, meeting the description of heading 0302. Subheading 030221 explicitly lists "halibut" and must be distinguished from other flatfish under the same heading (such as 0302.22). At the same time, it is necessary to confirm that the state is fresh or chilled, rather than frozen, dried, etc. 030222 Fresh or chilled flatfish (excluding halibut): 030222 covers other flatfish, such as European plaice and yellowtail flounder, while 030221 specifically refers to halibut. The difference lies in the species; halibut is larger in size and has a different scientific name. 030311 Frozen halibut: 030311 is frozen halibut, in frozen state, while 030221 is fresh or chilled. The core difference is the preservation state; frozen must be classified under 0303. 030431 Fresh or chilled halibut fillets: 030431 is fresh or chilled halibut fillets, already processed into slices, while 030221 is whole or simply gutted, not sliced. 030551 Dried halibut: 030551 is dried halibut, dehydrated, while 030221 is fresh or chilled, not dried. 03022100 Fresh or chilled halibut (China tariff 10-digit): In the China tariff, 03022100 is a 10-digit code; the first 6 digits are consistent with HS, and the last 4 digits are national subheadings. Attention must be paid to using the 10-digit code when declaring. Confirm that the commodity state is fresh or chilled, not frozen, dried, or salted. Confirm that the species is halibut and the Latin scientific name is accurate. Confirm that it has not been processed into fillets or other fish meat. Check whether packaging and labels are consistent with the declaration. Check the latest tax rates and regulatory conditions to ensure compliance.

How to distinguish fresh or chilled halibut from frozen halibut? Fresh or chilled halibut remains at 0-4°C without freezing and is classified under 030221; frozen halibut has a core temperature below -18°C and is classified under 030311. The key is the state: chilled fish is soft, while frozen fish is hard. Are halibut and flatfish the same species? Halibut is a type of flatfish, but flatfish include multiple families, such as Pleuronectidae and Bothidae. Halibut specifically refers to the genus Hippoglossus in the family Pleuronectidae, and classification must be precise to the species. Is it necessary to provide the Latin scientific name when declaring? Yes, the Latin scientific name is key to proving the species, especially for fish classification. Customs may require the scientific name to confirm the subheading and avoid misclassification under other flatfish. If halibut is headed and gutted, is it still classified under 030221? Yes, heading and gutting are simple processing and do not change the fresh or chilled state, so it is still classified under 030221. However, if sliced or made into fillets, it is classified under 0304. How to check the import tax rate for 030221? You can check the Import and Export Tariff of the People's Republic of China or the website of the General Administration of Customs. Tax rates may vary due to trade agreements, origin, etc., and the latest announcements should prevail. For cross-border e-commerce sales of halibut, is the classification different? The classification principles are the same, but cross-border e-commerce may involve personal items or cargo channels, and classification should be based on the actual state and processing method. Retail packaging does not affect the HS code, but may affect regulatory conditions. Is halibut an endangered species? Some halibut populations may be protected; for example, Atlantic halibut is listed as endangered by the IUCN, but CITES controls must be checked specifically. When importing, legal fishing certificates must be provided to ensure compliance. How to fill in the "Brand" in the declaration elements? If the commodity has a brand, fill in the brand name; if there is no brand, fill in "none". Brand does not affect classification, but affects valuation and intellectual property protection, and must be declared truthfully.
