Chapter 16 is a chapter under the HS classification system's broad category of 'Preparations of meat, of fish or of crustaceans, molluscs or other aquatic invertebrates,' specifically covering 'Preparations of meat, of fish or of crustaceans, molluscs or other aquatic invertebrates.' This chapter includes processed animal food products (such as cooked, fried, salted, smoked, etc.), but does not include animal products that have only been simply frozen, refrigerated, or are fresh (classified under Chapters 2 and 3). The processed products of this chapter are usually seasoned or mixed with other ingredients, and the degree of processing exceeds simple treatment. Heading 1605 covers 'Crustaceans, molluscs and other aquatic invertebrates, prepared or preserved by other methods.' This heading includes crustaceans (such as shrimp, crab, lobster), molluscs (such as squid, octopus, clams) and other aquatic invertebrates (such as sea cucumber, sea urchin) that have been processed by cooking, frying, salting, smoking, drying, etc. However, note that crustaceans that have only been simply frozen or refrigerated remain classified under Chapter 3. Products under this heading are usually already seasoned or canned, and can be consumed directly or require further cooking. HS code 160521 is a six-digit subheading code. The first 2 digits '16' represent Chapter 16, the chapter on prepared animal food products. Digits 3-4 '05' represent heading 1605, i.e., 'Crustaceans, molluscs and other aquatic invertebrates, prepared or preserved by other methods.' Digits 5-6 '21' represent subheading 160521, specifically referring to 'Shrimp products.' Note that subheading 160521 is further subdivided into: 16052110 (canned shrimp) and 16052190 (other shrimp products). Therefore, 160521 is the parent subheading for shrimp products, and actual classification requires further determination of the eight-digit or ten-digit code based on whether it is canned. This product is classified under 160521 because it is a shrimp product that has been prepared or preserved, and its degree of processing exceeds simple freezing, refrigeration, or fresh shrimp. If shrimp has only been frozen or refrigerated, it should be classified under Chapter 3 (such as 0306); if shrimp has only been simply salted or smoked but not cooked, it may be classified under Chapter 3; if shrimp has been cooked, fried, seasoned, or otherwise processed, it is classified under 1605. In addition, if the shrimp product is canned, it is classified under 16052110; if not canned, it is classified under 16052190.

Product Name: The specific name of the declared commodity, such as 'frozen cooked shrimp meat,' 'fried shrimp,' 'canned shrimp,' etc., which must be consistent with the actual product. Processing Method: A detailed description of the processing technique, such as 'cooked,' 'fried,' 'smoked,' 'seasoned,' 'canned,' etc. State: The state of the commodity, such as 'frozen,' 'refrigerated,' 'dried,' 'canned,' etc. Ingredient Content: Shrimp meat content, other ingredients (such as starch, seasonings) and moisture, etc., expressed as percentages. Packaging Specifications: Packaging form and specifications, such as '200g/can,' '1kg/bag,' etc., which affect whether it is classified as canned. Brand: The brand of the commodity; if no brand, fill in 'none.' Production Date: Production date or batch number, used for traceability. Product Name: Frozen cooked shrimp meat; Processing Method: Cooked then frozen; State: Frozen; Ingredient Content: Shrimp meat 95%, water 3%, salt 2%; Packaging Specifications: 1kg/bag, 10 bags/carton; Brand: ABC; Production Date: 2025-01-15. Misreporting 'frozen cooked shrimp' as 'frozen shrimp,' resulting in classification under Chapter 3 instead of 1605. Ignoring the 'canned' state, failing to declare as 16052110, and incorrectly classifying under 16052190. Failing to specify the shrimp meat proportion in ingredient content, which may raise questions about classification accuracy.

The core basis for classification is the processing method and state of the commodity. First, determine whether it has been 'prepared or preserved': if only frozen, refrigerated, simply salted or smoked (not cooked), it should be classified under Chapter 3; if cooked, fried, seasoned, canned, etc., it is classified under Chapter 16. Second, within Chapter 16, classify under 1605 (crustaceans, molluscs, etc.) according to the animal species. Finally, under 1605, shrimp products are classified under 160521, and further subdivided into 16052110 or 16052190 based on whether they are canned. 0306 Fresh, chilled, frozen crustaceans: 0306 covers unprocessed crustaceans that have only been frozen or refrigerated; 160521 covers shrimp products that have been cooked, seasoned, or otherwise processed. 160510 Crab products: 160510 covers processed crab products, while 160521 covers processed shrimp products; the species are different. 160529 Other prepared or preserved shrimp: 160529 covers other shrimp processed products besides 160521 (shrimp products)? Note: Actually 160521 is shrimp products, 160529 is other? Need to verify. According to HS, 160521 is shrimp products, 160529 is other? But usually 160521 is shrimp, 160529 is other crustaceans? Recommend verification. 160540 Other crustacean products: 160540 covers products of other crustaceans (such as lobster, other than crab), while 160521 specifically refers to shrimp products. Has it been cooked, fried, seasoned, or otherwise processed? Has it only been frozen or refrigerated? Is it canned? Is the shrimp meat content clearly stated? Does the packaging affect canned classification?

Which HS code should frozen cooked shrimp meat be classified under? Frozen cooked shrimp meat has been cooked, so it should be classified under Chapter 16, specifically 160521 (shrimp products). If canned, it is classified under 16052110; if not canned, under 16052190. Note that frozen uncooked shrimp meat is classified under 0306. How to distinguish between 160521 and 0306? The key is the processing method: 0306 covers fresh, chilled, frozen crustaceans that have only been simply frozen or refrigerated; 160521 covers shrimp products that have been cooked, fried, seasoned, etc. If shrimp has only been frozen, even if shelled, it remains classified under 0306. What is the difference in classification between canned shrimp and ordinary shrimp products? Canned shrimp is classified under 16052110, while other shrimp products are classified under 16052190. Canned products must meet specific packaging and sterilization processes, and packaging specifications and processing methods must be provided during declaration. What elements are required when declaring shrimp products? Product name, processing method, state, ingredient content, packaging specifications, brand, production date, etc. are required. The processing method must specify whether it is cooked, fried, seasoned, or canned, and the ingredient content must specify the shrimp meat proportion. What common mistakes are made when classifying shrimp products? Common mistakes include: misreporting frozen cooked shrimp as frozen shrimp (classified under 0306); ignoring the canned state leading to subheading errors; failing to provide shrimp meat content leading to classification disputes. It is recommended to carefully check the processing technique and packaging. If the shrimp product is seasoned then dried, where should it be classified? Seasoned then dried shrimp products still belong to prepared or preserved shrimp and should be classified under 160521. However, if only salted then dried, without cooking, it may be classified under 0306. Judgment should be based on the specific process. For cross-border e-commerce sales of shrimp products, how to look up the HS code? You can use the General Administration of Customs website or HS code query tools, enter keywords 'shrimp products' or 'shrimp products,' and determine based on the processing method. It is recommended to consult a professional customs broker to ensure accurate classification.
