Chapter 87 covers various motor vehicles other than railway vehicles, tractors, motorcycles, bicycles and other non-motor vehicles, and their parts and accessories. Commodities under this chapter are classified from complete vehicles to specialized parts and components, divided by vehicle type and function. Heading 8708 covers parts and accessories of motor vehicles, and is a heading with extremely high customs declaration frequency in international trade, involving numerous commodities in the automotive industry chain. Heading 8708 includes parts and accessories of motor vehicles of headings 8701 to 8705, covering braking systems, transmissions, drive axles, wheels, suspension systems, steering systems, etc. This heading is further subdivided into multiple subheadings classified by part function and the system to which they belong. As the core component of the drive axle, the final drive gear is a transmission system part and is classified under this heading. Code 870855 is a 6-digit subheading: the first 2 digits 87 indicate Chapter 87 (vehicles and their parts); digits 3-4, 08, indicate heading 8708 (parts and accessories of motor vehicles); digits 5-6, 55, indicate subheading 8708.55, namely "final drive gears." In the HS classification, subheadings are further subdivided by part function, and 8708.55 specifically refers to final drive gears, distinguished from other transmission parts such as transmission gears (8708.40) or drive axle housings (8708.50). The final drive gear is the core gear component inside the drive axle that reduces speed and increases torque, and is a part of the motor vehicle transmission system. Its function and structure conform to the description of subheading 8708.55, rather than being classified under general gears (8483) or transmission parts (8708.40). Because it is dedicated to vehicle drive axles, it is classified under 8708.55 rather than other parts subheadings.

Product Name: The Chinese and foreign language names of the declared commodity should accurately reflect the product attributes, such as "final drive gear" or "Main reducer gear." Brand: Fill in the manufacturer or brand name; if there is no brand, fill in "no brand"; it must be consistent with the actual product. Model: Fill in the specific model or part number of the commodity to facilitate customs identification and classification. Applicable Vehicle Model: Indicate the vehicle type or specific model to which the gear applies, such as "light truck" or "a certain brand and model." Material: Explain the material of the gear, such as alloy steel, carbon steel, etc., which affects classification and customs valuation. Use: Describe the function of the gear, such as "used in the final drive of a drive axle to reduce speed and increase torque." Processing Technology: Briefly describe the manufacturing process, such as forging, gear hobbing, heat treatment, etc., to assist in determining classification. Whether in Complete Knockdown Sets: Indicate whether it is declared in the form of complete knockdown sets, which affects classification and applicable tax rates. Customs declaration example: Product Name: Final drive gear Brand: ABC Model: XYZ-123 Applicable Vehicle Model: Light truck Material: Alloy steel Use: Used in the final drive of a drive axle to reduce speed and increase torque Processing Technology: Forging followed by gear hobbing and heat treatment Whether in Complete Knockdown Sets: No HS Code: 87085500 Quantity: 100 pieces Unit: Piece Total Price: USD 5,000 Country of Origin: China Mistakenly classifying final drive gears as transmission gears (8708.40), resulting in incorrect codes. Failure to indicate the applicable vehicle model, causing customs to question classification accuracy. False declaration of material, such as declaring alloy steel as carbon steel, affecting customs valuation and classification.

The core basis for classification is the Import and Export Tariff and the HS Explanatory Notes. Final drive gears are dedicated to motor vehicle drive axles, with the function of reducing speed and increasing torque, conforming to the description of subheading 8708.55. Judgment should be made based on the commodity's structure, use, and installation position. If it is a general gear, it is classified under 8483; if it is a transmission part, it is classified under 8708.40. 870840 Transmission parts: 870840 covers transmissions and their parts. Although the final drive gear is a gear, it is dedicated to the drive axle and is not a transmission part. 870850 Drive axle parts: 870850 covers drive axles and their parts, but final drive gears are separately listed under subheading 870855, so 870855 takes priority. 848340 Gears and gearing: 848340 covers general gears. If the final drive gear is not dedicated to motor vehicles, it is classified under this code. 870899 Other motor vehicle parts: 870899 covers parts not elsewhere specified. Final drive gears already have a specific subheading, so they are not classified under 870899. Is it dedicated to motor vehicle drive axles? Does it have the structural characteristics of a final drive gear? Is it confused with transmission gears? Is it already separately listed under subheading 870855? Are declaration elements such as applicable vehicle model required?

How can I look up the HS code for final drive gears? You can use the General Administration of Customs tariff inquiry system and enter the keyword "final drive gear" or "870855." You may also refer to the Import and Export Tariff and the HS Explanatory Notes to confirm whether the commodity conforms to the subheading description. It is recommended to make a comprehensive judgment based on the actual function, use, and structure of the commodity. What is the difference between the HS codes for final drive gears and transmission gears? Final drive gears are classified under 870855, and transmission gears under 870840. Although both are gears, their installation positions and functions differ: final drive gears are used in drive axles, while transmission gears are used in transmissions. When declaring, the use and installation position must be accurately described. What information is required to declare final drive gears? Declaration elements such as product name, brand, model, applicable vehicle model, material, use, processing technology, and whether they are in complete knockdown sets are required. It is recommended to attach product drawings, specifications, or photos to facilitate customs review and classification. How can I check the import tax rate for final drive gears? Tax rates change with national policy adjustments. You can check the latest tax rate by entering HS code 870855 on the General Administration of Customs website or a tariff inquiry platform. You may also consult a professional customs broker or international trade consultant. If the final drive gear is used in non-motor vehicles, which code should it be classified under? If used in non-motor vehicles, such as bicycles or tractors, it may be classified under other chapters. For example, bicycle gears are classified under 8714, and tractor gears under 8708 (if they are tractor parts). Judgment must be made based on the specific vehicle type. What is the export tax rebate situation for final drive gears? The export tax rebate rate must be checked according to the latest policy, usually through the electronic tax bureau or the customs export tax rebate system. It is recommended to consult the local tax authority or a professional tax rebate agent. What are the consequences of incorrectly filling in the brand and model during declaration? It may lead to customs classification errors, valuation disputes, or administrative penalties. Brand and model are important references for classification. Incorrect declaration may affect customs clearance efficiency and may even be deemed false declaration. It must be consistent with the actual product. How can I determine whether final drive gears belong to complete knockdown sets? If the gear is declared as a separate part and is not assembled with other parts, it is not a complete knockdown set. If it is declared together with other drive axle parts, it may be deemed a complete knockdown set and must be classified according to the corresponding rules.
