9108.90.70.00 - Valued over $15 each

This HTS category, 9108.90.70.00, specifically classifies complete and assembled watch movements that are valued over $15 each. These movements are the intricate mechanisms that power a watch, comprising components such as the balance wheel, mainspring, and gear train. The key differentiator for inclusion here is their valuation exceeding the $15 threshold.

It is important to distinguish this category from its sibling, "Valued not over $15 each." The sole criterion for differentiation is the declared or assessed value of the watch movement. Movements falling into this category meet the technical specifications of having over 7 jewels but not over 17 jewels, and measuring 33.8 mm or less in diameter, while also exceeding the $15 valuation mark.

As this is a leaf node within the HTS structure, there are no further subcategories branching from this specific code. Therefore, classification under 9108.90.70.00 is definitive based on the enumerated characteristics: completeness and assembly, a jewel count between 8 and 17, a diameter of 33.8 mm or less, and a value exceeding $15.
