Chapter 87 covers all land motor vehicles other than railway and tramway rolling stock, tractors, motorcycles, bicycles, vehicles for persons with disabilities, and other land vehicles, as well as their parts and accessories. The core of this chapter lies in 'motor vehicles' and their dedicated parts, but note that not all vehicle parts are classified in this chapter; only parts dedicated to or principally used with vehicles of this chapter are classified here, while general-purpose parts are classified according to their material. Heading 8708 covers parts and accessories of motor vehicles (headings 8701 to 8705), including braking systems, gearboxes, drive axles, wheels, suspension systems, radiators, mufflers, clutches, steering systems, etc. However, note that this heading does not include tires, internal combustion engines, batteries, and other goods that already have independent headings. Code 870850 is a 6-digit subheading. The first 2 digits '87' indicate Chapter 87 (Vehicles and Their Parts and Accessories). Digits 3-4 '08' indicate heading 8708 (Parts and Accessories of Motor Vehicles). Digits 5-6 '50' indicate subheading 870850, specifically drive axles and their parts. The drive axle is a key component of a vehicle's drivetrain, responsible for transmitting power from the propeller shaft to the drive wheels after speed reduction and differential action, and for bearing the vehicle's weight. Its parts include the axle housing, half shafts, differential housing, final drive gears, etc. The goods are drive axles and their parts, dedicated to motor vehicles, meeting the description of heading 8708 'Parts of Motor Vehicles'. They are not classified under other subheadings of 8708 (such as 870840 gearboxes) because the drive axle has an independent function; they are not classified under 8483 (propeller shafts, bearings, and other general mechanical parts) because the drive axle is a vehicle-specific assembly; they are not classified under 8709 (parts of short-distance transport vehicles) because the use is different.

Product Name: The Chinese and foreign language names of the declared goods, which should accurately reflect the product attributes, such as 'drive axle' or 'drive axle part (half shaft)'. Brand: Fill in the vehicle or part brand, such as 'Dongfeng', 'FAW', etc.; if no brand, fill in 'no brand'. Model: Fill in the specific model of the drive axle or part, such as 'DF153', '457', etc., used to distinguish specifications. Applicable Vehicle Type: Indicate the vehicle type to which the drive axle applies, such as 'heavy truck', 'light bus', etc. Material: Main material, such as 'cast iron', 'alloy steel', etc., which affects part classification. Is It an Assembly: Declare whether it is a complete drive axle assembly or a part; assemblies are classified under 870850, and parts are also classified under the same subheading. Part Number: If there is an original equipment manufacturer (OEM) part number, it should be filled in to facilitate customs verification. Product Name: Drive axle assembly; Brand: Dongfeng; Model: DF153; Applicable Vehicle Type: Heavy truck; Material: Cast iron axle housing, alloy steel gears; Is It an Assembly: Yes; Part Number: 2401001-DF153. Remarks: This drive axle is used for 8704 vehicles and has speed reduction and differential functions. Misclassifying drive axle parts as gearbox parts (870840); attention must be paid to functional differences. Ignoring the 'dedicated use' principle and classifying general-purpose gears under 870850, when they should actually be classified by material. Failure to indicate the applicable vehicle type during declaration, leading customs to question whether it falls within the scope of 8708.

Core basis for classification: 1) The goods must be dedicated to or principally used with motor vehicles of headings 8701-8705; 2) They must be drive axles or their parts, with power transmission, speed reduction, and differential functions; 3) They cannot be general-purpose parts (such as bearings, gears, etc.) unless they have become dedicated drive axle parts; 4) Reference must be made to the Explanatory Notes to the Import and Export Tariff of the People's Republic of China for 8708. 870840 Gearboxes and their parts: Gearboxes are responsible for changing gear ratios, while drive axles are responsible for speed reduction and differential action. If a part is dedicated to a gearbox, it is classified under 870840; if dedicated to a drive axle, it is classified under 870850. 848340 Gears and gearing: General-purpose gears and gearboxes are classified under 848340, but drive axle gears dedicated to vehicles are classified under 870850. 870899 Other vehicle parts: 870899 is for parts not elsewhere specified under 8708; drive axles already have subheading 870850, so they are not classified under 870899. 870850 Drive axles and their parts: This code itself, but note the distinction from 870860 (non-drive axles and their parts), which refers to driven axles. 848310 Propeller shafts: Propeller shafts are components connecting the gearbox and drive axle, classified under 848310; drive axles are assemblies, classified under 870850. Is it dedicated to motor vehicles of Chapter 87? Does it have drive axle functions (speed reduction, differential, load bearing)? Is it a general-purpose part? If so, classify by material. Is it confused with gearbox parts? Is it already included in other subheadings of 8708?

How to distinguish drive axle parts from general-purpose gears? Drive axle parts must be dedicated to drive axles, such as half shafts, axle housings, differential housings, etc. If general-purpose gears can be used in other machinery, they should be classified by material (such as 8483). If gears are dedicated to drive axles and are not interchangeable, they are classified under 870850. Are drive axles for electric vehicles also classified under 870850? Yes, as long as they are used for electric vehicles of headings 8701-8705, their drive axles are still classified under 870850. However, note that drive axles for pure electric vehicles may include motors; if the motor and axle are integrated, judgment must be made according to the classification principles for complete vehicle parts. What is the difference in declaration between drive axle assemblies and parts? Both assemblies and parts are classified under 870850, but the declaration elements must indicate 'Is It an Assembly'. Assemblies require a complete functional description, and parts require the assembly to which they belong and the part number. How to inquire about the import tariff rate for drive axles? The tariff rate must be determined based on the country of origin, trade agreements, etc. It can be inquired through the Import and Export Tariff of the People's Republic of China or through the General Administration of Customs website or the single window. Note that tariff rates may be adjusted annually. What documents are required for exporting drive axle parts? Generally, a contract, invoice, packing list, customs declaration form, and detailed specifications, model, applicable vehicle type, etc. of the drive axle are required. If a brand is involved, brand authorization or declaration must be provided. What is the classification difference between drive axles and driven axles? Drive axles are classified under 870850, and driven axles (non-drive axles) are classified under 870860. The difference lies in whether power is transmitted. Driven axles only support and steer, and do not transmit power. How are drive axle parts classified if they are general-purpose standard parts? General-purpose standard parts such as bolts, nuts, and bearings, even if used in drive axles, should be classified by material (such as 7318, 8482) and not under 870850. What are common errors in the declaration elements of drive axles during customs declaration? Common errors include: broad product names, failure to indicate the applicable vehicle type, unclear material descriptions, declaring assemblies disassembled as parts, ignoring part numbers, etc. It is recommended to fill in details carefully and check the tariff notes.
