9104.00.10 - Electric (including battery operated)

This HTS category encompasses electric instrument panel clocks and similar timekeeping devices designed for use in vehicles, aircraft, spacecraft, or vessels, specifically when these clocks have a movement measuring over 50 millimeters in width or diameter and are valued at $10 or less each. The "Electric (including battery operated)" descriptor at this level highlights the power source as a key defining characteristic. These are typically functional and robust timepieces integral to the operation or monitoring of transportation equipment, rather than purely decorative or personal clocks.

Within this specific node, the distinction from its sibling category, 9104.00.20.00 "Other," lies in the implied exclusion or different treatment of items that do not meet the specific criteria outlined in the parent headings that lead to this sub-classification. Since this is a leaf node, there are no further subcategories to introduce. The classification is therefore determined by the confluence of the clock's nature (electric, instrument panel type), its physical dimensions (movement over 50mm), its intended application (vehicles, etc.), and its unit value (not over $10).
