9104.00.40.00 - Other

This HTS subcategory, "Other," at 9104.00.40.00, encompasses instrument panel clocks and similar clocks designed for vehicles, aircraft, spacecraft, or vessels, which have clock movements exceeding 50 mm in width or diameter and are valued over $10 each. This classification serves as a residual category for clocks meeting these specific dimensional and value thresholds but which are not electric or battery-operated.

The key differentiator for this category is the absence of electric or battery power as the primary timekeeping mechanism. While the sibling category 9104.00.30 specifically covers electric and battery-operated clocks within the same dimensional and value parameters, this "Other" category applies to clocks that utilize mechanical winding or other non-electric means for their operation.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification within 9104.00.40.00 relies on confirming that the clock is intended for use in the specified modes of transport, meets the size and value criteria, and is not powered by electricity or batteries. Examples would include purely mechanical chronometers or dashboard clocks with spring-driven movements.
