Chapter 16 is the chapter of the Harmonized Commodity Description and Coding System for 'Preparations of meat, of fish, of crustaceans, molluscs or other aquatic invertebrates', covering deeply processed aquatic animal products that have been cooked, salted, smoked, canned, etc. Products of this chapter have usually changed their original form and are no longer classified as fresh or chilled/frozen, but are classified under the corresponding headings according to the processing method and composition, such as 1604, 1605, etc. Heading 1605 covers 'Crustaceans, molluscs and other aquatic invertebrates, prepared or preserved by other methods', including octopus, squid, cuttlefish, shrimp, crab, shellfish, etc. Under this heading, it is further subdivided by specific species. Octopus products correspond to subheading 1605.55, namely octopus prepared or preserved (whether or not in airtight containers). Code 160555 is a six-digit subheading: the first two digits '16' indicate Chapter 16 (preparations of aquatic animals); the 3rd-4th digits '05' indicate heading 1605 (crustaceans, molluscs and other aquatic invertebrates, prepared or preserved by other methods); the 5th-6th digits '55' are the subheading specifically referring to octopus products. Among them, '55' is the specific identifier for octopus in the HS classification, distinguished from squid (1605.54), cuttlefish (1605.53), etc. Octopus products are classified under 1605.55 because they are molluscs and have been prepared or preserved (such as cooked, seasoned, canned), rather than fresh, chilled or frozen octopus (classified under 0307). At the same time, they are not octopus merely smoked or salted (which may be classified under 0307 or 0210), so 1605.55 is the code that precisely corresponds to deeply processed octopus products.

Product name: The specific name of the declared commodity, such as 'seasoned octopus', 'canned octopus', etc., which must be consistent with the actual goods. Method of preparation or preservation: Detailed description of the processing technology, such as cooking, seasoning, canning, smoking, etc., and whether further processing has been carried out. Ingredient content: List the proportion of octopus content and other ingredients (such as seasonings, preservatives), which affects classification and tax rates. Packaging specifications: Explain the packaging form (such as canned, vacuum bag) and net weight, used for statistics and supervision. Brand: Declare the brand of the commodity; if there is no brand, indicate 'no brand', used for customs protection of intellectual property rights. Production date: Indicate the production date and shelf life, used for food safety supervision. Product name: seasoned octopus; Method of preparation: cooked then seasoned, canned; Ingredient content: octopus 80%, water 10%, sugar 5%, salt 3%, others 2%; Packaging specifications: 200g/can, 24 cans/carton; Brand: ABC; Production date: 2025-01-01; Shelf life: 24 months. Incorrectly classifying octopus products under 0307 (fresh, chilled, frozen octopus), ignoring the processing state. Incomplete declaration elements, such as failure to indicate the method of preparation, leading customs to question the classification. False declaration of ingredient content, which may affect the application of tax rates and food safety supervision.

The core basis for classification is the processing state and composition of the commodity. If octopus products have undergone deep processing such as cooking, seasoning, canning, and octopus is the main ingredient, they should be classified under 1605.55. If only simply salted, smoked or frozen, they may be classified under 0307 or 0210. In addition, it is necessary to confirm whether they are mixed products; if they contain other animal ingredients, classification may be affected. 0307 Fresh, chilled, frozen octopus: 0307 is octopus not prepared or preserved, only simply cleaned, frozen, etc.; 1605.55 is deeply processed through cooking, seasoning, etc. 1605.54 Squid products: 1605.54 is for squid, 1605.55 is for octopus; the two are different species and must be accurately distinguished during classification. 1605.53 Cuttlefish products: 1605.53 is cuttlefish products, which are biologically different from octopus and must not be confused. 1604 Fish products: 1604 covers fish products; octopus is a mollusc and should be classified under 1605. 2106 Other food preparations: If octopus products are only used as an ingredient and the content is low, they may be classified under 2106, but this must be determined based on the specific composition. Has the octopus undergone deep processing such as cooking or seasoning? Is octopus the main ingredient of the product? Is it canned or in retail packaging? Is it mixed with other species (such as squid)? Does the processing method go beyond simple freezing or salting?

How can I inquire about the HS code for octopus products? You can use the official website of the General Administration of Customs or an HS code inquiry tool, enter the keyword 'octopus products' or search by Chapter 16, heading 1605, and confirm subheading 1605.55. Note that the processing state must meet the definition of 'prepared or preserved'. What is the difference between the codes for octopus products and frozen octopus? Frozen octopus is classified under 0307 (fresh, chilled, frozen molluscs), while octopus products (such as cooked, seasoned) are classified under 1605.55. The key difference lies in whether they have undergone deep processing that changes their original state. What key elements need to be provided when declaring octopus products? Product name, method of preparation, ingredient content, packaging specifications, brand, production date, etc. are required. The method of preparation should be specific, such as 'cooked, seasoned and canned', and the ingredient content must list the proportion of octopus. With which codes are octopus products easily confused during classification? They are easily confused with 0307 (frozen octopus), 1605.54 (squid products), and 1605.53 (cuttlefish products). Key points of distinction: species (octopus vs squid) and processing state (deep processing vs simple treatment). If octopus products contain other seafood, how should they be classified? If octopus is the main ingredient, they are still classified under 1605.55; if other ingredients account for a high proportion, they may be classified according to the main ingredient or under 2106. A comprehensive judgment must be made based on the proportion of ingredients and the processing method. Are HS codes consistent when octopus products are exported to different countries? The first six digits of the HS code are basically consistent internationally, but countries may subdivide subsequent digits. It is recommended to consult the customs tariff of the target country to confirm the specific code and regulatory conditions. What are the key points of customs inspection when octopus products are imported? The focus is on checking whether the product name, processing method, and ingredient content are consistent with the declaration, as well as whether they come from an approved country and whether there is a quarantine permit. Labels and food safety standards are also often checked. Can octopus products enjoy preferential tariff rates under free trade agreements? It is necessary to confirm whether octopus products are included in the agreement's tariff reduction list and provide a certificate of origin. Different agreements have different tariff rates. It is recommended to consult the specific provisions of the agreement or consult a professional customs broker.
