Chapter 03 covers all fish, crustaceans, molluscs and other aquatic invertebrates, including live, fresh, chilled, frozen, dried, salted, smoked and other preservation methods. This chapter does not include processed fish products (such as canned fish, fish balls, etc., classified under Chapter 16), nor aquatic mammals (classified under Chapter 01) or aquatic plants (classified under Chapter 06 or Chapter 12). Heading 0303 specifically refers to frozen fish, but excludes fish fillets and other fish meat (classified under 0304). This heading covers whole frozen fish, headless frozen fish, gutted frozen fish, etc., whether or not cut, as long as they are not prepared into fillets or fish meat blocks. Freezing methods include conventional freezing, quick freezing, etc., but the fish must maintain its whole form or simply cut state. The first 2 digits "03" represent Chapter 03, i.e., fish, crustaceans, molluscs and other aquatic invertebrates. Digits 3-4 "03" represent heading 0303, i.e., frozen fish, distinguished from 0301 (live fish), 0302 (fresh or chilled fish), 0304 (fresh or chilled fish fillets and other fish meat), 0305 (dried, salted or brined fish; smoked fish). Digits 5-6 "51" represent subheading 030351, i.e., frozen herring (Clupea harengus, Clupea pallasii), distinguished from 030352 (frozen cod), 030353 (frozen sardines) and other frozen fish subheadings. The product is frozen herring, which is whole or simply cut frozen fish that has not undergone further processing (such as being made into fillets, surimi, etc.), therefore classified under 0303 rather than 0304 (fish fillets and fish meat). Meanwhile, herring belongs to a specific species, further subdivided under 0303 to 030351, rather than other frozen fish subheadings.

Product name (Chinese and foreign language): Fill in the Chinese name and English name of the product, such as "冻鲱鱼" and "Frozen herring", ensuring correspondence with the HS code. Latin scientific name: Fill in the Latin scientific name of herring, such as Clupea harengus or Clupea pallasii, to accurately correspond to subheading 030351. Method of production or preservation: Indicate "frozen", and specify the freezing method (such as conventional freezing, quick freezing), ensuring compliance with the definition of frozen under 0303. State (whole, headless, gutted, etc.): Describe the overall state of the fish, such as "whole", "headless and gutted", "cut but not filleted", etc., to distinguish between 0303 and 0304. Specifications (weight per carton, weight per fish, etc.): Fill in packaging specifications and weight range per fish, such as "10kg/carton, 200-300g/fish", to facilitate customs inspection and statistics. Packaging type: Specify inner and outer packaging materials, such as "inner plastic bag, outer carton", ensuring compliance with food hygiene requirements. Brand (if any): Fill in the brand name (such as "XX brand"), or "none" if no brand. Brand affects customs intellectual property recordation verification. Production date and shelf life: Fill in the production date and shelf life, ensuring compliance with the importing country's food safety standards, to facilitate customs supervision. Product name: Frozen herring; Latin scientific name: Clupea harengus; Method of production and preservation: Frozen (quick frozen); State: Whole gutted; Specifications: 10kg/carton, 200-300g/fish; Packaging: Inner plastic bag, outer carton; Brand: None; Production date: 2025-01-15; Shelf life: 24 months. Incorrectly declaring as "fresh herring" or "chilled herring", leading to classification under 0302 rather than 0303, affecting tariffs and regulatory conditions. Declaring boneless herring fillets as "frozen herring", which should actually be classified under 0304, leading to classification errors. Ignoring the Latin scientific name and not specifying the specific species, possibly resulting in inability to enjoy the specific treatment of subheading 030351.

Core classification criteria: 1) The product must be frozen fish, not fresh, chilled, dried, salted, etc.; 2) It must be whole or simply cut (headless, gutted, etc.), not made into fillets or fish meat blocks; 3) It must be herring genus (Clupea harengus or Clupea pallasii), not other fish species. Additionally, reference should be made to the Import and Export Tariff and General Administration of Customs classification decisions to ensure accurate classification under 030351. 0302 Fresh or chilled herring: 0302 is fresh or chilled preservation, 0303 is frozen; different preservation methods, tariffs and regulatory conditions may differ. 0304 Fresh or chilled fish fillets and other fish meat: 0304 is fish fillets or fish meat blocks (whether fresh, chilled or frozen), 0303 is whole or simply cut frozen fish; different forms. 0305 Dried, salted or brined fish; smoked fish: 0305 is dried, salted, smoked and other processing, 0303 is only frozen; different processing methods. 030352 Frozen cod: 030352 is cod, 030351 is herring; different fish species, clear subheading distinction. 030353 Frozen sardines: 030353 is sardines, 030351 is herring; different fish species, accurate identification required for classification. Is it confirmed as frozen (not fresh, chilled, dried, salted)? Is it whole or simply cut (not fillets or fish meat blocks)? Is the Latin scientific name accurately filled in (herring genus)? Have the customs tariff and classification decisions been verified? Have the packaging and labels been checked for compliance with importing country requirements?

How to check the tariff rate for HS code 030351? You can check through the General Administration of Customs of China website, the International Trade Single Window, or the Import and Export Tariff. Enter HS code 030351 to view the MFN rate, general rate, VAT and consumption tax (if applicable). Note that rates may change with free trade agreements and policy adjustments; it is recommended to refer to the latest official data. What is the difference in classification between frozen herring and frozen herring fillets? Frozen herring (whole or simply cut) is classified under 030351; frozen herring fillets (boneless, sliced) are classified under 0304. The key difference lies in form: 0303 allows headless, gutted, but not made into fillets; 0304 is fish fillets or fish meat blocks. The state must be accurately described during declaration. Is it necessary to provide the Latin scientific name during declaration? Yes, the Latin scientific name is key to distinguishing herring from other fish species. 030351 only covers Clupea harengus and Clupea pallasii. Providing the scientific name can avoid classification disputes and ensure correct subheading treatment. What regulatory documents are required for importing frozen herring? Typically, a certificate of origin, health certificate, import and export business license, customs declaration form, contract, invoice, packing list, etc. are required. Some countries may require quarantine permits. Specific requirements are subject to customs and inspection and quarantine authorities. If frozen herring is salted but not dried, which code should it be classified under? Salted herring (not dried) should be classified under 0305 (dried, salted or brined fish). 0303 only covers frozen, without salting, smoking or other processing. If salted and then frozen, it should be determined based on the degree of processing, usually classified under 0305. What is the difference between 030351 and 030359? 030351 specifically refers to frozen herring; 030359 is other frozen fish (such as frozen anchovies, frozen mackerel, etc.). The difference lies in the fish species; 030351 is limited to herring genus, while 030359 covers other frozen fish not elsewhere specified. Does cross-border e-commerce retail import of frozen herring apply to 030351? Yes, cross-border e-commerce retail imports also need to be classified according to the HS code. Frozen herring is classified under 030351, but attention should be paid to the cross-border e-commerce retail import commodity list and tax policies, which may apply different rates and regulatory conditions. How to avoid classification errors for frozen herring? Recommendations: 1) Accurately describe the product state (frozen, whole, gutted, etc.); 2) Provide the Latin scientific name; 3) Refer to customs classification decisions; 4) Consult professional customs brokers or customs. Incorrect classification may result in supplementary taxes, fines or delays.
