9109.10.60 - Measuring not over 50 mm in width or diameter

This HTS classification, 9109.10.60, specifically covers complete and assembled electrically operated clock movements that measure not over 50 mm in width or diameter. This subcategory encompasses the intricate internal mechanisms of clocks, including gears, motors, and any associated electronic components, provided these movements meet the specified dimensional limitation and are powered by electricity. These are distinct from other assembled clock movements that might be manually operated or designed for larger timepieces.

Within the broader category of electrically operated clock movements, this particular heading is further refined by a subsequent "Other" designation, indicating it is a specific subset not otherwise detailed. As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into this code hinges entirely on the electrical operation of the assembled clock movement and its physical dimensions of not exceeding 50 mm in width or diameter. Examples would include movements for small alarm clocks, digital watches, or miniature desk clocks.
