9105.19.30 - Having over one jewel

This HTS classification, 9105.19.30, pertains to "Other clocks" that function as alarm clocks, are not over 50 mm in width or diameter, and are designed to operate for more than 47 hours without rewinding, specifically those possessing "over one jewel" in their movement. This category encompasses a range of alarm clocks, typically portable or bedside models, where the presence of multiple jewels within the clockwork mechanism is a key distinguishing feature. The "over one jewel" criterion refers to the use of synthetic rubies or sapphires (jewels) to reduce friction and improve the accuracy and longevity of the clock's internal mechanism.

Crucially, this classification is distinguished from its sibling category, 9105.19.20, by the number of jewels present in the movement. While 9105.19.20 covers alarm clocks with no jewels or only a single jewel, 9105.19.30 specifically captures those equipped with two or more jewels. This distinction is important for importers and exporters as it directly impacts the tariff rate applied.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the classification hinges entirely on the fulfillment of all preceding criteria: being an alarm clock, its dimensions, its extended operational capacity without rewinding, and the presence of multiple jewels in its movement. Examples might include small, travel-sized alarm clocks with advanced internal mechanisms designed for enhanced durability and precision, often found in higher-end consumer electronics or specialty travel accessories.
