8708.50.85.00 - Half-shafts

This HTS classification, 8708.50.85.00, specifically covers "Half-shafts" which are integral components of drive-axles. A half-shaft, also known as a drive shaft or CV axle, is a component of the drivetrain responsible for transmitting power from the differential to the wheels of a vehicle. It typically comprises a shaft with universal joints or constant velocity (CV) joints at each end, allowing for the transmission of rotational power while accommodating suspension movement and steering angles. These are designed for use with motor vehicles of heading 8703, which primarily includes passenger cars and other vehicles principally designed for the transport of persons.

This subheading is distinguished from its sibling category, 8708.50.89.00 "Other," by its specific identification as half-shafts. While both fall under the broader category of parts for drive-axles, 8708.50.85.00 is for the direct classification of the half-shaft component itself. The "Other" subheading would encompass any remaining parts or accessories of drive-axles with differentials for vehicles of heading 8703 that are not specifically classified as half-shafts. This distinction ensures precise classification based on the specific nature of the part.

As this is a leaf node, there are no further subcategories. Therefore, the focus remains on the precise definition and application of half-shafts within the context of drive-axle assemblies for passenger vehicles. When classifying under this heading, consider that the primary function of transmitting power from the differential to the drive wheels, often incorporating flexible joints to accommodate movement, is the defining characteristic of a half-shaft.
