Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh, chilled, frozen, dried, salted, smoked and other processed products, but excludes prepared or preserved aquatic products (classified under Chapter 16). This chapter is the core chapter for the classification of aquatic products in international trade, involving fishing, aquaculture, processing and other stages. Heading 0303 covers frozen fish (excluding fish fillets and other fish meat of heading 0304), including whole, headless, gutted, cut into pieces and other forms, but excluding fish fillets, fish steaks and other deeply processed products. This heading is subdivided by fish species, such as salmonids, tilapia, cod, etc., with 030319 covering other salmonids. The first 2 digits 03 represent Chapter 03 (Fish and aquatic invertebrates); digits 3-4, 03, represent heading 0303 (Frozen fish, excluding fish fillets and other fish meat of heading 0304); digits 5-6, 19, represent subheading 030319, i.e., other salmonids, referring to salmonids other than 030311 (Sockeye salmon), 030312 (Other Pacific salmon), 030313 (Atlantic salmon and Danube salmon), such as Arctic char, river trout, etc. The goods are frozen salmonids and do not belong to specifically named species such as sockeye salmon, Pacific salmon, Atlantic salmon or Danube salmon, and are therefore classified under 030319. If fresh or chilled salmonids, they should be classified under 0302; if fish fillets, under 0304; if smoked, under 0305.

Product Name: Fill in the specific commodity name, such as frozen Arctic char, frozen river trout, etc., which must correspond to the HS code. Latin Scientific Name: Fill in the Latin scientific name of the fish for accurate species identification, such as Salvelinus alpinus. Method of Production or Preservation: Indicate "frozen" and specify whether headless, gutted, cut into pieces, etc. State: Describe the state of the goods, such as whole, headless and gutted, cut into pieces, etc. Specifications: Fill in specifications such as individual weight and body length, e.g., 500-800 grams per fish. Brand: Fill in the brand name; if no brand, write "None". Production Date: Fill in the processing or packaging date in the format YYYY-MM-DD. Storage Temperature: Fill in the frozen storage temperature, such as below -18°C. Product Name: Frozen Arctic char; Latin Scientific Name: Salvelinus alpinus; Method of Production or Preservation: Frozen, headless and gutted; State: Whole; Specifications: 600-1000 grams per fish; Brand: None; Production Date: 2025-01-15; Storage Temperature: Below -18°C; Manufacturer: XX Aquatic Products Co., Ltd.; Origin: Norway. Mistakenly classifying frozen salmonids under 0302 (fresh or chilled), ignoring the frozen state. Failing to distinguish specific species and mistakenly classifying Atlantic salmon under 030319, when it should actually be 030313. Mistakenly classifying fish fillets under 0303, when fish fillets should actually be under 0304.

Core basis for classification: 1) The goods are salmonids; 2) The state is frozen; 3) They are not fish fillets or other fish meat; 4) They do not belong to the specifically named species under 030311, 030312 or 030313. Reference should also be made to the Explanatory Notes to the Import and Export Tariff and the Customs classification decisions. 030313 Frozen Atlantic salmon and Danube salmon: 030313 is limited to Atlantic salmon and Danube salmon; 030319 covers other salmonids, such as Arctic char. 030214 Fresh or chilled Atlantic salmon: 030214 is fresh or chilled; 030319 is frozen; the preservation state is different. 030441 Fresh or chilled Pacific salmon fillets: 030441 is fresh or chilled fillets; 030319 is frozen whole fish or cut pieces; the degree of processing is different. 030541 Smoked Pacific salmon: 030541 is smoked; 030319 is frozen; the processing method is different. Confirm the fish species is a salmonid and is not a specifically named species such as Atlantic salmon or Pacific salmon. Confirm the preservation state is frozen, not fresh, chilled or smoked. Confirm the commodity form is whole, headless and gutted, or cut into pieces, not fillets. Verify the Latin scientific name to ensure accurate classification. Check whether it has undergone further processing, such as seasoning or cooking; if not, classify under 0303.

How to determine whether frozen salmonids are classified under 030319? First confirm the fish species belongs to Salmonidae and does not belong to the specifically named species under 030311, 030312 or 030313; second confirm the preservation state is frozen, not fresh or chilled; finally confirm the commodity form is whole, headless and gutted, or cut into pieces, not fillets. If the above conditions are met, classify under 030319. What is the difference between 030319 and 030313? 030313 includes only frozen Atlantic salmon and Danube salmon, while 030319 includes other salmonids, such as Arctic char, river trout, etc. Accurate species identification is required during classification to avoid confusion. Which code should frozen salmonid fillets be classified under? Frozen salmonid fillets should be classified under 0304, with the specific subheading depending on the species, such as 030481 for frozen Pacific salmon fillets. 030319 applies only to whole, headless and gutted, or cut pieces of frozen salmonids. What special documents are required for declaring 030319? Usually a certificate of origin, health and quarantine certificate, fishing certificate or aquaculture certificate, packing list, invoice, contract, etc. are required. Specific requirements are subject to customs; it is recommended to consult a customs broker in advance. How to check the tariff rate for 030319? You can check the Import and Export Tariff of the People's Republic of China or the website of the General Administration of Customs, and determine the applicable rate based on origin, trade agreements, etc. Rates may change; it is recommended to refer to the latest published version. If salmonids are seasoned but not cooked, are they still classified under 030319? If only simply seasoned (such as salted) and not cooked, they may still be classified under 0303, but this depends on the specific processing method. If seasoned and then cooked, they are classified under Chapter 16. What inspection and quarantine requirements apply to imported frozen salmonids? They must comply with the Measures for the Supervision and Administration of Inspection and Quarantine of Imported and Exported Aquatic Products, provide an official health certificate from the exporting country, and undergo customs inspection and quarantine. Specific requirements can be found in announcements of the General Administration of Customs. How to distinguish 030319 from 030389 (other frozen fish)? 030319 specifically covers salmonids, while 030389 covers other frozen fish (non-salmonids). During classification, first determine whether the fish species belongs to Salmonidae; if so, 030319 should be considered first.
