9113.90 - Other:

This HTS category, 9113.90, encompasses watch straps, watch bands, and watch bracelets, as well as their respective parts, that are not made of precious metal or metal clad with precious metal (9113.10) nor of base metal, whether or not gold- or silver-plated (9113.20). Essentially, it acts as a residual category for these watch accessories when their primary composition falls outside the specified metallic categories.

The primary distinguishing factor for this category lies in its material composition. While sibling categories focus specifically on precious metals, metal clad with precious metals, and base metals, 9113.90 is designed for watch accessories manufactured from a wide range of other materials. This includes, but is not limited to, materials like plastics, rubber, leather, and textiles.

Within this broader category, further distinctions are made to refine classification. Subcategory 9113.90.40.00 specifically addresses watch straps, bands, and bracelets made from textile materials. All other remaining watch straps, bands, bracelets, and their parts, which do not fall under the textile classification and are not composed of precious metals or base metals as defined in the sibling categories, are classified under 9113.90.80.00, the "Other" subdivision. This tiered approach allows for precise classification based on the dominant material of the watch accessory.
