9113.20 - Of base metal, whether or not gold- or silver-plated:

This HTS category, 9113.20, specifically covers watch straps, watch bands, and watch bracelets, along with their parts, when they are constructed from base metal. Base metal includes common metals such as iron, steel, copper, aluminum, and their alloys. This classification also encompasses items where the base metal has been plated with gold or silver, provided the plating is not substantial enough to classify the item as precious metal.

Crucially, this category distinguishes itself from its sibling, 9113.10, which exclusively covers watch straps, bands, and bracelets made of precious metal or metal clad with precious metal. Therefore, any article predominantly composed of gold, silver, platinum, or their alloys, or those significantly clad with these precious metals, would fall under 9113.10. Articles in 9113.20, by contrast, are primarily base metal with an optional overlay of precious metal.

Within this category, further subdivisions exist to refine classification. The subcategories for "Straps, bands and bracelets" and "Parts" allow for a distinction between the complete wearable items and individual components thereof. This granular approach helps ensure accurate tariff application based on the specific nature and intended use of the base metal watch accessories being imported or exported.
