8483.90.80 - Other

HTS code 8483.90.80 encompasses "Other" parts for transmission elements, which are presented separately and are not specifically classified under other subheadings within 8483.90. This category serves as a residual classification for components of gears, gearing, toothed wheels, chain sprockets, and other transmission elements that do not fit into more specific part classifications.

This category is distinguished from its sibling, 8483.90.70.00, which specifically covers "Parts of articles of subheading 8483.20" (bearing housings, housed bearings, and plain shaft bearings). Therefore, 8483.90.80 applies to parts of the transmission elements described in the broader heading 8483 that are *not* parts of bearing housings or housed bearings.

The subcategories under 8483.90.80 provide further refinement. 8483.90.80.10 specifically classifies parts of articles covered by subheading 8483.60.80 (which deals with other clutches and shaft couplings). 8483.90.80.40 is designated for parts of universal joints. Finally, 8483.90.80.80, as an "Other" category itself, captures any remaining parts of transmission elements not otherwise specified within the 8483.90.80 family or its parent headings.
