9114.90 - Other:

This HTS category, "Other," under heading 9114.90, encompasses a broad range of clock and watch parts and accessories that are not specifically enumerated in the preceding subheadings of 9114. This includes components that are essential for the functioning or assembly of timekeeping devices but do not fit into the more defined categories of dials or plates and bridges. The scope is intentionally broad to capture all remaining qualifying parts.

The distinction between 9114.90 and its sibling categories, 9114.30 (Dials) and 9114.40 (Plates and bridges), lies in specificity. Dials refer to the face of the clock or watch displaying the time, while plates and bridges are fundamental structural components of the movement. This "Other" category is therefore for any part not falling under these distinct classifications, such as screws, gears, levers, or cases, provided they are specifically parts for clocks or watches.

Within this "Other" category, further subdivisions exist to provide more granular classification. These include specific subcategories for "Jewels," which are synthetic rubies or sapphires used as bearings to reduce friction in high-precision movements. Additionally, there are provisions for "Assemblies and subassemblies for watch or clock movements," which are pre-constructed combinations of two or more parts. Finally, "Springs, including hairsprings," which are crucial for storing and releasing energy, are also separately classified, further defining the diverse range of components covered by 9114.90.
