9108.90.50.00 - Measuring not over 15.2 mm 🖩

This HTS classification, 9108.90.50.00, pertains to complete and assembled watch movements that measure no more than 15.2 millimeters in any one dimension. These movements are a component of watches and are characterized by their precise internal mechanisms designed for timekeeping. The specific criteria for inclusion here, beyond being a complete assembled movement, include its physical dimensions and its jeweling count (implied by the parent categories).

This category is distinct from its sibling, 9108.90.60.00, solely based on a critical physical measurement. While both cover watch movements, 9108.90.50.00 specifically applies to those measuring *not over* 15.2 mm, whereas 9108.90.60.00 covers movements measuring *over* 15.2 mm. This precise dimensional distinction is the sole determinant for classification between these two subheadings.

As this is a leaf node within the HTS, there are no further subcategories to introduce. The classification is finalized at this level based on the established criteria of being a complete assembled watch movement, with a jeweling count within the specified range (over 7 but not over 17 jewels), a value not exceeding $15 each, and a maximum dimension of 15.2 mm.
