Chapter 87 covers vehicles other than railway or tramway rolling stock, and parts and accessories thereof, including motor vehicles, tractors, motorcycles, bicycles, wheelchairs, etc. Within the chapter, complete vehicles and parts are listed separately: headings 8701 to 8705 cover complete vehicles, 8706 to 8708 cover parts, and 8709 to 8716 cover other special vehicles. The core is transport equipment and their dedicated parts and accessories, but general machinery parts are not classified in this chapter. Heading 8708 covers parts and accessories of motor vehicles (8701 to 8705), including bumpers, brakes, gearboxes, drive axles, wheels, suspension systems, steering systems, etc. However, they must be solely or principally for motor vehicles and not more specifically named in other headings of Chapter 87. Subheadings are subdivided by part type, such as 8708.10 bumpers, 8708.40 gearboxes, etc. First 2 digits 87: Chapter 87 vehicles and parts and accessories thereof. Digits 3-4 08: Heading 8708, parts and accessories of motor vehicles. Digits 5-6 48: Subheading 8708.48, other parts of transmissions. Specifically, 8708.40 is gearboxes and parts thereof, and 8708.48 is other parts of transmissions, i.e., dedicated transmission parts not named in 8708.40, such as gears, shafts, synchronizers, shift mechanisms, etc. Note that 8708.48 is a 6-digit subheading and may be further subdivided in some countries' tariff schedules. The goods are transmission parts but are not specifically named in 8708.40 (gearboxes and parts thereof), so they are classified under 8708.48 'other'. If they were complete gearboxes, they would be classified under 8708.40; if they were clutches, under 8708.50; if they were drive axle parts, under 8708.60. 8708.48 specifically refers to dedicated parts not named elsewhere within transmissions, such as gears, shafts, synchronizer rings, etc.

Product name: The specific name of the declared commodity, such as 'transmission synchronizer ring', 'transmission input shaft', etc., which must be consistent with the actual goods. Brand type: Fill in the brand attribute, such as 'no brand', 'domestic independent brand', 'foreign brand (OEM production)', etc. Export preference status: If applicable, fill in 'export goods enjoy preferential tariffs in the final destination country', etc.; otherwise fill in 'no preference'. Use: Explain what type of vehicle and transmission the part is suitable for, such as 'for manual transmission of light trucks'. Material: Main material, such as 'alloy steel', 'cast iron', 'powder metallurgy', etc. Brand: Fill in the actual brand name; if no brand, fill in 'none'. Part number: The part number or drawing number provided by the manufacturer for identification. Applicable vehicle model: The specific applicable vehicle model or series, such as 'suitable for Toyota Corolla 1.8L'. Product name: transmission synchronizer ring; Brand type: no brand; Export preference status: no preference; Use: for manual transmission of light trucks; Material: alloy steel; Brand: none; Part number: SYN-12345; Applicable vehicle model: suitable for Isuzu N-series light trucks. Classifying a complete gearbox under 8708.48 when it should actually be under 8708.40. Mistakenly classifying clutch parts under 8708.48 when they should be under 8708.50. Failure to provide part number or applicable vehicle model, making it impossible to determine specificity.

Core classification basis: 1. The goods must be solely or principally for motor vehicles of 8701 to 8705; 2. They must be transmission parts and not specifically named in 8708.40; 3. Reference should be made to the Explanatory Notes to the Harmonized System for 8708.48, i.e., the 'other' subheading includes transmission gears, shafts, synchronizers, shift forks, etc.; 4. If the parts are general-purpose (usable in other machinery), they may be classified under Chapter 84. 8708.40 Gearboxes and parts thereof: 8708.40 includes complete gearboxes and named gearbox parts, such as gearbox housings, gear cases, etc. 8708.48 includes only other transmission parts not named elsewhere. 8708.50 Clutches and parts thereof: Clutches and their parts are classified under 8708.50, including clutch discs, pressure plates, etc. Transmission parts are not classified here. 8708.60 Drive axles and parts thereof: Drive axles and their parts are classified under 8708.60, including differentials, half-shafts, etc. Transmission parts are not classified here. 8483.40 Gears and gearing: If transmission gears are general-purpose gears, they may be classified under 8483.40, but gears dedicated to motor vehicle transmissions are classified under 8708.48. 8708.99 Other parts of motor vehicles: 8708.99 is for other parts not elsewhere specified or included; if transmission parts are clearly classified under 8708.48, they are not classified here. Are they solely or principally for motor vehicles? Are they transmission parts rather than complete gearboxes? Are they not specifically named in 8708.40? Are they distinguished from clutch and drive axle parts? Are they general-purpose and therefore possibly classifiable under Chapter 84?

What specific parts does 'other' in HS code 870848 refer to? It refers to dedicated transmission parts not named in 8708.40, such as gears, shafts, synchronizers, shift mechanisms, bearing housings, etc. However, note that if these parts are more specifically named in other subheadings, they should be classified there first. How to distinguish between 8708.40 and 8708.48? 8708.40 includes complete gearboxes and named gearbox parts, such as gearbox housings, gearbox assemblies, etc. 8708.48 includes only other transmission parts not named elsewhere. If a part is specifically named in 8708.40, it should be classified under 8708.40. Should transmission gears be classified under 8708.48 or 8483.40? If the gears are dedicated to motor vehicle transmissions and are not named in 8708.40, they should be classified under 8708.48. If the gears are general-purpose gears usable in various machinery, they are classified under 8483.40. The key is specificity. How can it be proven at declaration that the parts are dedicated to motor vehicles? Part numbers, applicable vehicle models, technical drawings, contracts, etc., can be provided to prove that they are dedicated to a certain type of vehicle transmission. Customs may require supplementary explanations. How to check the import tariff rate for 8708.48? Tariff rates change. It is recommended to check the latest tariff rates in the Import and Export Tariff published by the General Administration of Customs of China or through the 'Internet + Customs' platform. You may also consult a professional customs broker. If the transmission parts are used or refurbished, is the classification different? The classification principles are the same, but note that used parts may involve import prohibitions or additional regulatory conditions. It is recommended to indicate the condition at declaration and check relevant regulations. For cross-border e-commerce sales of transmission parts, how to choose the HS code? It should be determined based on the specific function and specificity of the part. If it is a dedicated part for motor vehicle transmissions, classify under 8708.48; if it is a general-purpose part, classify under Chapter 84. It is recommended to consult a professional classifier. What is the difference between 8708.48 and 8708.99? 8708.48 specifically refers to other transmission parts, while 8708.99 is for other motor vehicle parts not elsewhere specified or included. If the part is clearly a transmission part, it should be classified under 8708.48 first.
