9114.40.20.00 - Watch movement bottom or pillar plates or their equivalent

This HTS category, 9114.40.20.00, specifically covers bottom plates and pillar plates, or their equivalent components, designed for watch movements. These are essential foundational parts of a mechanical watch, providing the base structure onto which other movement components, such as gears and bridges, are mounted. Their primary characteristic is their role in supporting and aligning the intricate mechanism of a watch.

Distinguishing this category from its sibling, 9114.40.40.00, is crucial. While both deal with plates for clock movements, 9114.40.40.00 refers to any plate, or set of plates, intended for the assembly of a clock movement. In contrast, 9114.40.20.00 is limited to plates specifically for *watch* movements and more precisely identifies them as the "bottom or pillar" plates, indicating their foundational and structural function within the watch's intricate gearing.

As this node represents a leaf category within the HTS, there are no further subcategories. Therefore, classification within 9114.40.20.00 is determined by the specific identification of the part as a watch movement bottom or pillar plate, or a component serving the direct equivalent function in the assembly of a watch movement.
