8708.50.91 - Parts of non-driving axles

This HTS code, 8708.50.91, specifically covers parts of non-driving axles intended for motor vehicles classified under headings 8701 to 8705. A non-driving axle is a component of a vehicle's suspension and steering system that supports the weight of the vehicle and its load but does not transmit power from the engine to the wheels. Examples include stub axles, axle beams, and axle housings that are not part of a drive axle assembly.

This classification is distinct from its sibling category, "Other," which would encompass parts of non-driving axles not otherwise specified or that do not fit into a more granular subcategory. It also differentiates from drive axles and their parts, as those are designed to transmit power to the wheels and would fall under different subheadings within 8708.50.

The subcategories under 8708.50.91, "Spindles" (8708.50.91.10) and "Other" (8708.50.91.50), further refine the classification. "Spindles" refers to the rotating shafts that support the wheels and are integral to the steering mechanism of non-driving axles. The "Other" category serves as a residual for any remaining parts of non-driving axles that are not specifically identified as spindles, ensuring comprehensive coverage for this component group.
