8708.50.91.10 - Spindles

This HTS category, 8708.50.91.10, specifically classifies "Spindles" that are parts of non-driving axles for vehicles falling within headings 8701 to 8705. A spindle, in this context, refers to the component of a non-driving axle assembly that supports the wheel hub and allows it to rotate. It is a crucial element for the steering and braking functions of vehicles, as it holds the wheel bearings and provides the connection point for the brake mechanism. These spindles are distinct from the entire non-driving axle itself, focusing on this specific, load-bearing component.

Within the broader classification of "Parts of non-driving axles" (8708.50.91), this subcategory (8708.50.91.10) is differentiated from its sibling category, 8708.50.91.50 ("Other"). While the "Other" category encompasses all other parts of non-driving axles not specifically enumerated, this category is dedicated solely to the spindle component. Therefore, an item classified here is exclusively a spindle and not another part like a brake drum or a mounting bracket, unless those are integrated with the spindle in a way that its primary function remains that of a spindle.

As this is a leaf node within the HTS structure, there are no further subcategories under 8708.50.91.10. Classification at this level is determined by identifying the component as a spindle and confirming its intended use as a part of a non-driving axle for the specified vehicle types. The focus is on the specific physical characteristics and the singular function of the spindle within the axle assembly.
