Chapter 03 covers fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh or chilled, frozen, dried, smoked, salted and other preservation methods. This chapter is the core classification chapter for international trade in aquatic products, involving the entire chain of fishing, aquaculture and processing. Within the chapter, headings are divided by species, preservation state and degree of processing, forming a clear boundary with Chapter 16 (preparations). Heading 0303 refers specifically to frozen fish (whether or not sliced), but excludes fish fillets and other fish meat (classified under 0304). It covers whole fish, headless and gutted fish, fish blocks, etc., which must be preserved by deep freezing. Under this heading, subheadings are further divided by species, with Danube salmon listed separately as a specific species, reflecting the trade concerns of markets such as the EU for this species. Code 030314 is a six-digit subheading: the first 2 digits '03' represent Chapter 03 (fish and aquatic invertebrates); digits 3-4 '03' represent heading 0303 (frozen fish, but excluding fillets of 0304); digits 5-6 '14' represent subheading 030314, specifically referring to frozen Danube salmon (Hucho hucho). This subheading is set up independently in HS2022, distinct from other frozen salmonidae fish (such as 030313 frozen Atlantic salmon, 030319 other frozen salmonidae fish). Danube salmon (Hucho hucho) belongs to the Salmonidae family but is not Atlantic salmon or Pacific salmon, and is traded in whole or gutted frozen form, not sliced. Therefore it is classified under 030314, rather than 030313 (Atlantic salmon) or 030319 (other salmonidae fish). If sliced, it is classified under 0304; if smoked, under 0305.

📝 Declaration Elements
Product name: The specific name of the declared commodity, which should use standard Chinese and Latin scientific name, such as 'Frozen Danube salmon (Hucho hucho)'. Latin scientific name: Fill in the Latin scientific name of the species; Danube salmon is Hucho hucho, ensuring correspondence with the HS subheading. Preservation state: State the freezing method, such as 'whole frozen', 'headless and gutted frozen', 'block frozen', etc., which must be consistent with the requirements of heading 0303. Processing method: Describe whether headed, gutted, sliced, etc. Only if not sliced can it be classified under 0303; if sliced, under 0304. Specification: Declare by weight or size, such as '2-3 kg each', for customs statistics and valuation. Origin: The country/region of fishing or farming, affecting tariffs and trade control measures. Brand: If there is a brand, declare the brand name; if no brand, fill in 'none'. Product name: Frozen Danube salmon; Latin scientific name: Hucho hucho; Preservation state: whole frozen; Processing method: headless and gutted, not sliced; Specification: 2-3 kg each; Origin: Austria; Brand: none; HS code: 03031400. Mistakenly classifying sliced Danube salmon under 0303, when it should actually be under 0304. Incorrect Latin scientific name, leading to subheading classification deviation. Filling in preservation state as 'ice-chilled' but actually frozen, causing customs questioning.
Product name

⚠️ Writing only 'frozen fish' or 'salmon' without specifying the exact species.
Latin scientific name
Fill in the Latin scientific name of the species; Danube salmon is Hucho hucho, ensuring correspondence with the HS subheading.
⚠️ Mistakenly writing Salmo hucho or Oncorhynchus nerka.
Preservation state
State the freezing method, such as 'whole frozen', 'headless and gutted frozen', 'block frozen', etc., which must be consistent with the requirements of heading 0303.
⚠️ Filling in 'ice-chilled' or 'refrigerated', leading to classification errors.
Processing method
Describe whether headed, gutted, sliced, etc. Only if not sliced can it be classified under 0303; if sliced, under 0304.
⚠️ Filling in 'sliced' but still declaring under 0303.
Specification
Declare by weight or size, such as '2-3 kg each', for customs statistics and valuation.
⚠️ Vaguely writing 'mixed large, medium and small', lacking specific specifications.
Origin
The country/region of fishing or farming, affecting tariffs and trade control measures.
⚠️ Writing only 'Europe' without specifying the country.
Brand
If there is a brand, declare the brand name; if no brand, fill in 'none'.

Example： Product name: Frozen Danube salmon; Latin scientific name: Hucho hucho; Preservation state: whole frozen; Processing method: headless and gutted, not sliced; Specification: 2-3 kg each; Origin: Austria; Brand: none; HS code: 03031400.
Common Mistakes：
Mistakenly classifying sliced Danube salmon under 0303, when it should actually be under 0304.
Incorrect Latin scientific name, leading to subheading classification deviation.
Filling in preservation state as 'ice-chilled' but actually frozen, causing customs questioning.
🎯 Classification Logic
The core basis for classification is: 1) whether the species is Danube salmon (Hucho hucho); 2) whether the preservation state is frozen; 3) whether it has undergone processing such as slicing. Only when all three conditions of Danube salmon, frozen, and not sliced are met can it be classified under 030314. If it is other salmonidae fish, it is classified under 030313 or 030319; if sliced, under 0304; if smoked, under 0305. 030313 Frozen Atlantic salmon: Atlantic salmon (Salmo salar) is a different species; Danube salmon is Hucho hucho, and the two must not be confused. 030319 Other frozen salmonidae fish: This subheading is a residual provision; Danube salmon has been listed separately and is not classified here. 0304 Frozen fish fillets and other fish meat: If Danube salmon is sliced or made into steaks, it is classified under 0304, not 0303. 0305 Smoked fish and fish fillets: If Danube salmon is smoked, it is classified under 0305; frozen storage does not apply. Is the species Danube salmon? Has it undergone frozen preservation? Is it not sliced? Is it not smoked or salted? Is the Latin scientific name correct?
