Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh or chilled, frozen, dried, salted and smoked processed products. This chapter does not include cooked or preserved aquatic products (classified under Chapter 16), nor ornamental fish (0301), aquatic mammals (0106), etc. The core distinction lies in the degree of processing: those subjected only to simple preservation are classified under this chapter, while those deeply processed are classified under Chapter 16. Heading 0303 covers frozen fish, but excludes fillets and other fish meat (0304), fish livers and roes (0305), etc. Frozen means the fish is cooled below the freezing point to be completely frozen for long-term preservation. This heading includes whole fish, headed and gutted frozen fish and other simply processed frozen fish, but does not include further processed frozen fish products (such as breaded, seasoned), which are classified under Chapter 16. The first 2 digits 03 represent Chapter 3 'Fish, crustaceans, molluscs and other aquatic invertebrates'. The 3rd-4th digits 03 represent heading 0303 'Frozen fish, excluding fish fillets and other fish meat of heading 0304'. The 5th-6th digits 22 represent subheading 0303.22 'Frozen Atlantic salmon (Salmo salar) and Danube salmon (Hucho hucho)'. The 22 is the specific species code; Atlantic salmon and Danube salmon share this subheading, but Danube salmon is extremely rare, and in actual trade it is almost entirely Atlantic salmon. This commodity is frozen Atlantic salmon, not further processed, meeting the definition of heading 0303 'Frozen fish'. And the species is Atlantic salmon, so it is classified under subheading 0303.22. If it were fresh or chilled Atlantic salmon, it would be classified under 0302.14; if smoked, under 0305.41; if filleted, under 0304.41, all different from this code.

Product Name: The specific name of the declared commodity, which should include the species and processing state, such as 'Frozen Atlantic salmon'. Avoid using common names such as 'salmon'. Latin Scientific Name: The accurate Latin scientific name must be provided; Atlantic salmon is Salmo salar, used for customs species verification and endangered species management. Processing Method: Describe the treatment before freezing, such as 'headed and gutted', 'whole', 'boneless', etc., as well as the freezing method (such as sea-frozen, land-frozen). State: Clearly indicate frozen, and specify whether the core temperature is below -18℃, and whether other preservation treatments have been applied. Specification: Graded by weight or size, such as '4-6kg/piece', which helps customs statistics and price review. Brand: If there is a brand, declare the brand name; if no brand, fill in 'None'. Origin: The country/region of capture or farming, such as Norway, Chile, Scotland, etc., which affects tariffs and trade agreements. Packaging Specification: The specifications of inner and outer packaging, such as '10kg/carton', for customs inspection and statistics. Product Name: Frozen Atlantic salmon; Latin Scientific Name: Salmo salar; Processing Method: headed and gutted, sea-frozen; State: frozen, core temperature -20℃; Specification: 4-6kg/piece; Brand: None; Origin: Norway; Packaging Specification: 10kg/carton. Misreporting the Latin scientific name as other salmonid fish, such as rainbow trout, leading to classification errors. Incomplete processing method description, not indicating whether headed and gutted, may be classified under other subheadings. Inaccurate origin declaration, affecting rules of origin and preferential tariff application.

The core basis for classification is the notes to Chapter 3 of the HS Code and the subheading texts. First confirm that the commodity is frozen fish and not further processed, meeting heading 0303. Second confirm that the species is Atlantic salmon (Salmo salar), meeting subheading 0303.22. If filleted, it is classified under 0304; if smoked, under 0305. At the same time, refer to the Import and Export Tariff and national subheading notes to ensure no special provisions. 030214 Fresh or chilled Atlantic salmon: 030214 is fresh or chilled Atlantic salmon, in an unfrozen state; 030322 is frozen, in a frozen state. The core difference lies in the preservation temperature and processing method. 030441 Fresh or chilled Pacific salmon fillets: 030441 is fresh or chilled Pacific salmon fillets, already sliced and not frozen; 030322 is frozen whole fish or simply processed, not sliced. 030541 Smoked Atlantic salmon: 030541 is smoked Atlantic salmon, subjected to smoking processing; 030322 is frozen, not smoked. Different processing methods lead to classification differences. 030481 Frozen Pacific salmon fillets: 030481 is frozen Pacific salmon fillets, species is Pacific salmon and already sliced; 030322 is Atlantic salmon, not sliced. Both species and processing state are different. Confirm whether the commodity is in a frozen state and whether the core temperature is below -18℃. Confirm whether the Latin scientific name is Salmo salar. Confirm whether it has undergone further processing such as slicing or smoking. Confirm whether it is headed and gutted, and whether this affects classification. Confirm the origin and whether a preferential trade agreement applies.

How to query the tariff rate for HS code 030322? You can query the MFN rate, general rate and agreement rate through the official website of the General Administration of Customs of China or the Import and Export Tariff. Enter HS code 030322 and the system will display the currently applicable rate. Note that rates may be adjusted with policy changes; it is recommended to refer to the latest version. What is the difference between the HS codes for frozen Atlantic salmon and fresh or chilled Atlantic salmon? Fresh or chilled Atlantic salmon is classified under 030214, and frozen under 030322. The main difference lies in the preservation state: fresh or chilled is around 0℃ and not frozen, while frozen is below -18℃ and frozen. Temperature proof must be provided during customs declaration. If the Atlantic salmon is headed and gutted, is it still classified under 030322? Yes, heading and gutting is simple processing that does not change the basic characteristics of the fish, so it is still classified under 030322. However, if further sliced, minced, etc., it may be classified under 0304. What is the difference between the Latin scientific names Salmo salar and Oncorhynchus nerka? Salmo salar is Atlantic salmon, classified under 030322; Oncorhynchus nerka is sockeye salmon (Pacific salmon), classified under 030312 or 030313, etc. The two are different species with different classifications and must be accurately declared. Can frozen Atlantic salmon imported from Norway enjoy the agreement rate? China and Norway do not have a free trade agreement, so the agreement rate does not apply, and the MFN rate usually applies. However, the certificate of origin must be confirmed; if it meets conditions such as least developed country status, preferences may apply. What are the consequences of forgetting to fill in the Latin scientific name during declaration? It may lead to customs rejection or inspection, delaying customs clearance. The Latin scientific name is an important basis for species regulation and must be truthfully declared. If falsely declared, administrative penalties may be imposed. Does frozen Atlantic salmon require an animal and plant quarantine permit? Imported aquatic products must meet the quarantine requirements of the General Administration of Customs. Usually an official quarantine certificate from the exporting country is required, but generally an advance entry animal and plant quarantine permit is not required, subject to the latest regulations. What HS code applies to cross-border e-commerce retail import of frozen Atlantic salmon? Cross-border e-commerce retail imports also use HS code 030322, but attention must be paid to list restrictions. Currently, frozen Atlantic salmon may not be on the positive list for cross-border e-commerce retail imports and must be imported through general trade.
