Chapter 87 covers vehicles and their parts and accessories in the Harmonized System, excluding railway and tramway vehicles. This chapter includes motor vehicles (such as cars, trucks, motorcycles), non-motor vehicles (such as bicycles, horse-drawn carriages), and parts and accessories specially or principally designed for these vehicles. As a key component of motor vehicles, the drive axle housing falls within the scope of parts under this chapter, rather than complete vehicles. Heading 8708 covers parts and accessories of motor vehicles, including body, chassis, transmission system, steering system, braking system and other components. Parts under this heading must be specially or principally designed for vehicles of headings 8701 to 8705. As part of the transmission system, the drive axle housing is used to mount the differential, half shafts, etc., and is a typical commodity under 8708. Code 870851 is a 6-digit subheading. The first 2 digits '87' represent Chapter 87 (Vehicles and their parts, accessories). Digits 3-4 '08' represent heading 8708 (Parts and accessories of motor vehicles). Digits 5-6 '51' represent subheading 8708.51, specifically drive axle housings (including differential housings). In HS classification, heading 8708 is further subdivided into various parts, and 870851 specifically refers to drive axle housings and related housings, distinguished from other transmission components such as gearbox housings (8708.40) or clutches (8708.93). The drive axle housing is the main structural component of a motor vehicle's drive axle, used to accommodate and protect transmission components such as the differential and half shafts, and to bear vehicle loads. It is neither a complete vehicle (first 4 digits of Chapter 87) nor a general-purpose part under other headings (such as Chapter 73 iron and steel articles), but a part specially designed for motor vehicles, thus classified under 8708. Under 8708, it is further classified under 870851 based on function, rather than 8708.99 (other parts), because it has a specific function and is specifically named.

Product Name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the product attributes, such as 'drive axle housing' or 'Drive axle housing'. Brand: Fill in the manufacturer or brand name; if no brand, indicate 'no brand'. Model: Fill in the specific model or part number of the commodity for identification. Applicable Vehicle Type: Indicate the vehicle type to which the drive axle housing applies, such as 'heavy truck', 'light bus', etc. Material: State the main material of the drive axle housing, such as cast iron, cast steel, aluminum alloy, etc. Processing Method: Describe the main processing techniques, such as casting, forging, machining, etc. Whether It Contains a Differential: Declare whether a differential is assembled; if it contains a differential, it may affect classification. Product Name: Drive axle housing; Brand: No brand; Model: DAH-2024; Applicable Vehicle Type: Heavy truck; Material: Cast steel; Processing Method: Casting followed by machining; Whether It Contains a Differential: No. Mistakenly classifying the drive axle housing under 8708.99, ignoring its specific listing. Failing to distinguish between a drive axle housing and a drive axle assembly, the latter of which may be classified under 8708.50. Inaccurate material declaration, such as reporting cast steel as cast iron, affecting classification.

The core basis for classification is the Import and Export Tariff and the Explanatory Notes to the Harmonized System. As the housing of a motor vehicle drive axle, the drive axle housing is specially or principally designed for vehicles of headings 8701 to 8705, meeting the description of heading 8708. Under 8708, according to functional listing, 8708.51 explicitly includes drive axle housings, so it is preferentially classified under this subheading. If the drive axle housing is combined with other components into an assembly, classification shall be based on the characteristics of the assembly. 870850 Drive axle assembly: A drive axle assembly includes the axle housing, differential, half shafts, etc., while a drive axle housing refers only to the housing itself. If the housing is imported separately, it should be classified under 870851; if a complete drive axle is imported, it is classified under 870850. 870840 Gearbox housing: The gearbox housing is used to accommodate gearbox gears and belongs to another part of the transmission system, classified under 870840; the drive axle housing is used for the drive axle, classified under 870851. 870899 Other motor vehicle parts: 870899 is for parts not elsewhere specified or included; the drive axle housing is already specifically listed, so it is not classified under this code. 732510 Cast iron articles: If the drive axle housing is made of cast iron and not specially designed for motor vehicles, it might be classified under Chapter 73, but because it is specially designed for vehicles, it remains under Chapter 87. Is it specially or principally designed for vehicles of Chapter 87? Is it already listed under 8708.51? Does it contain a differential or other components? Do material and processing method affect classification? Is it confused with a drive axle assembly?

What is the difference in HS codes between a drive axle housing and a drive axle assembly? A drive axle housing refers only to the housing itself, classified under 870851; a drive axle assembly includes the axle housing, differential, half shafts, etc., classified under 870850. At the time of import, it should be determined based on the actual state of the goods; if the differential etc. is not assembled, it is an axle housing. How can I check the import tariff rate for drive axle housings? Tariff rates vary by country, trade agreement, and country of origin. It is recommended to obtain the latest tariff rates through the official website of the customs administration, tariff query platforms, or by consulting a customs broker, while also considering free trade agreement preferences. In the declaration elements for a drive axle housing, why is it necessary to indicate whether it contains a differential? Because a drive axle housing containing a differential may be regarded as part of a drive axle assembly, affecting classification. If it is only the housing, it is classified under 870851; if it contains a differential, it may be classified under 870850. If a drive axle housing is used for non-motor vehicles, which code should it be classified under? Parts for non-motor vehicles are generally classified under other headings of Chapter 87, such as 8714 (bicycle parts). However, drive axle housings are generally used for motor vehicles; if used for non-motor vehicles, they need to be reclassified according to the specific use. Does the material of the drive axle housing affect the HS code? Generally not, because 870851 already covers drive axle housings of various materials. However, if the material is special (such as aluminum alloy), it should still be classified under the same code, because classification is based on function rather than material. When importing drive axle housings, how should the specifications and model be filled in on the customs declaration form? The complete model and part number should be filled in so that customs can identify them. At the same time, indicate the applicable vehicle type, material, processing method, etc., to ensure the declaration elements are complete. Is the HS code for drive axle housings globally uniform? The first 6 digits of the HS code are uniform worldwide, but countries may further subdivide the later digits. Therefore, when exporting, it is necessary to confirm the code subdivision of the destination country's customs. If the drive axle housing is second-hand or refurbished, is the HS code different? The HS code itself does not distinguish between new and old, but second-hand or refurbished goods may involve other regulatory conditions, such as licenses, inspection and quarantine, etc., which require additional attention.
