Chapter 87 covers motor vehicles other than railway and tramway rolling stock, tractors, motorcycles, bicycles and other land vehicles and their parts and accessories. It includes finished vehicles (such as passenger cars and trucks) and special-purpose vehicles (such as crane trucks and fire trucks), as well as vehicle parts (such as brakes, gearboxes and drive axles). However, electrical lighting equipment for motor vehicles is classified under Chapter 85, and internal combustion engines are classified under Chapter 84. This chapter is the core chapter for the classification of automobiles and parts in international trade. Heading 8708 is specifically for parts and accessories of motor vehicles of headings 8701 to 8705, including brakes, gearboxes, drive axles, wheels, suspension systems, radiators, mufflers, clutches, steering systems, etc. However, it does not include general-purpose parts (such as bolts and springs) or electrical parts (such as generators). This heading is further subdivided into multiple subheadings, divided according to part function or vehicle type. HS code 870847 is a six-digit subheading. The first 2 digits 87 = Chapter 87 (Vehicles and their parts); digits 3-4, 08 = Heading 8708 (Parts and accessories of motor vehicles); digits 5-6, 47 = Subheading 8708.47, referring to "Transmission seal". In HS classification, subheading 47 generally corresponds to transmission parts, and seals, as parts dedicated to transmissions, are classified under this subheading. Note that if the seal is a general-purpose rubber or plastic product, it may be classified under Chapter 40 or Chapter 39, but as a part dedicated to a transmission, it is classified under 8708.47. A transmission seal is a part dedicated to a motor vehicle transmission, with a specific shape and function, and cannot be classified as a general-purpose seal (such as rubber seals of Chapter 40) or mechanical seals of Chapter 84. According to General Rules of Interpretation 1 and 6, it conforms to the description of 8708 "Parts of motor vehicles", and subheading 8708.47 explicitly covers transmission parts, so it is classified under 870847.

Product name: The Chinese and foreign-language name of the declared commodity, which should accurately reflect the product's attributes, such as "transmission seal" or "Transmission seal". Brand: Fill in the manufacturer or brand name, such as "Bosch", "Aisin", etc.; if there is no brand, fill in "unbranded". Model: Fill in the specific model or part number of the commodity, such as "TF-80SC", "0AM325065". Applicable vehicle model: Indicate the vehicle type or transmission model to which the seal applies, such as "suitable for Volkswagen DQ200 transmission". Material: Explain the main material of the seal, such as "rubber", "fluoroelastomer", "polytetrafluoroethylene", etc. Use: Briefly describe the function, such as "used for transmission input shaft sealing to prevent oil leakage". Whether general-purpose: Declare whether it is a general-purpose part; if it is a dedicated part, proof of applicable vehicle model must be provided. Customs declaration example: Product name: Transmission seal Brand: Aisin Model: TF-80SC Applicable vehicle model: Volvo S60 2015 Material: Fluoroelastomer Use: Used for automatic transmission input shaft sealing Whether general-purpose: No Specifications: Outer diameter 50 mm, inner diameter 35 mm, thickness 8 mm Origin: Japan Remarks: Dedicated part, with a list of applicable vehicle models attached. Mistakenly classifying transmission seals under 8484 (mechanical seals) or 4016 (rubber seals), ignoring their dedicated nature. Failure to provide applicable vehicle model information at declaration, causing customs to question their dedicated nature and possibly classify them as general-purpose parts. Inaccurate declaration of material, such as declaring fluoroelastomer as ordinary rubber, affecting classification and tax rates.

Core basis for classification: 1) The commodity must be a dedicated part of a motor vehicle (8701-8705); 2) Functionally, it is a transmission part; 3) It conforms to the description of subheading 8708.47 "Transmission parts". If the seal is a general-purpose part (usable in other machinery), it is classified under Chapter 40 or Chapter 39 according to material. In addition, reference should be made to the Explanatory Notes to the Import and Export Tariff of the People's Republic of China on 8708 parts, as well as General Rules of Interpretation 1 and 6. 401693 Rubber seals: 4016 is for general-purpose rubber products. If the seal is not clearly used for a motor vehicle transmission, or can be used generally, it is classified under this code. In contrast, 870847 is dedicated to vehicle transmissions. 848420 Mechanical seals: 8484 is for mechanical sealing devices, usually used in pumps, compressors and other rotating machinery, rather than vehicle transmissions. If the seal is a mechanical seal and used in a transmission, it must be judged according to its dedicated nature. 870840 Transmissions and parts thereof: 870840 is for transmission assemblies and their parts, but 870847 specifically refers to transmission seals. If the seal is imported together with the transmission, it may be classified as part of the assembly, but if imported separately, it is classified under 870847. 870899 Other vehicle parts: 870899 is for motor vehicle parts not elsewhere specified or included. If the seal cannot be classified under 870847 (for example, if it is not for a transmission), it may be classified under this code. However, transmission seals should preferably be classified under 870847. Is the commodity dedicated to a motor vehicle transmission? Does it have the specific shape and function of a transmission seal? Does the material affect classification (for example, rubber may be classified under Chapter 40)? Is it imported together with the transmission assembly? Have the applicable vehicle model and part number been provided?

Which HS code should transmission seals be classified under? If a transmission seal is dedicated to a motor vehicle, it should be classified under 870847. However, note that if it is a general-purpose rubber seal, it may be classified under 401693. When classifying, proof of dedicated nature such as applicable vehicle model and part number must be provided. How do you distinguish between 870847 and 401693? 870847 is dedicated to motor vehicle transmission seals, with specific dimensions and functions; 401693 is for general-purpose rubber seals that can be used in various machinery. The key is whether it is dedicated to a vehicle transmission and whether it is imported together with transmission parts. What elements are required to declare transmission seals? It is necessary to declare the product name, brand, model, applicable vehicle model, material, use, whether it is general-purpose, etc. Providing the applicable vehicle model and part number can prove dedicated nature and avoid classification disputes. How can the import tax rate for transmission seals be checked? The tax rate must be checked according to the country of origin and trade agreements. You can visit the website of the General Administration of Customs of China or use the Import and Export Tariff to check the MFN rate, agreement rate, etc. for 870847. Note that tax rates change, and the latest announcement shall prevail. If a seal is used for multiple vehicle models, can it still be classified under 870847? If the seal is dedicated to motor vehicle transmissions, even if it is suitable for multiple vehicle models, it can still be classified under 870847. However, if it can be used in non-vehicle machinery, it may be regarded as a general-purpose part and classified under Chapter 40 or Chapter 84. What is the difference between transmission seals and transmission oil seals? Generally, "transmission seals" and "transmission oil seals" refer to the same type of commodity, both used to prevent transmission oil leakage. For classification, both are classified as transmission parts under 870847, but the declared product name should be accurate to avoid ambiguity. What documents are required to import transmission seals? Generally, a packing list, invoice, contract, bill of lading, customs declaration form, etc. are required. If customs questions the classification, product descriptions, a list of applicable vehicle models, material certificates, etc. may be required. It is advisable to prepare in advance. How are transmission seals sold through cross-border e-commerce classified? Cross-border e-commerce retail imports also need to be classified according to HS codes. Transmission seals should be classified under 870847, but attention should be paid to the personal item limit and the list of cross-border e-commerce retail imported goods. It is advisable to consult a professional customs broker.
