9108.90.40.00 - Other 🖩

This HTS category, 9108.90.40.00, encompasses watch movements that are complete and assembled, falling under the broader heading of "Other" watch movements. Specifically, this classification applies to those movements that possess more than one jewel but do not exceed seven jewels. Jewels in watch movements are primarily used as bearings to reduce friction and wear at critical pivot points, contributing to the longevity and accuracy of the timepiece.

The primary distinction for this category lies in the number of jewels. While 9108.90.30.00 is specifically designated for watch movements measuring 33.8 mm or less, this category (9108.90.40.00) focuses on the jewel count as the defining characteristic for movements that are not otherwise specifically enumerated. Therefore, a watch movement with, for example, five jewels and a diameter of 35 mm would fall here, whereas a movement with the same jewel count but a smaller diameter would be classified under the sibling category.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 9108.90.40.00 is definitive once the criteria of being a complete, assembled watch movement with more than one but not more than seven jewels are met, and it does not fit into any more specific provisions. This ensures precise and consistent categorization for customs purposes.
