9108.19.40 - Having no jewels or only one jewel

This HTS category, 9108.19.40, specifically encompasses complete and assembled electric watch movements that contain no jewels or only a single jewel. This designation is crucial for differentiating these simpler movements from those incorporating multiple jewels, which are designed to reduce friction and increase the longevity and accuracy of the watch mechanism. The "no jewels or only one jewel" criterion is the primary distinguishing factor for classification within this sub-heading.

Within the broader classification of electrically operated watch movements, 9108.19.40 stands apart from its sibling category, 9108.19.80, which covers "Other" electrically operated watch movements. While 9108.19.80 would encompass movements with more than one jewel, this category is strictly limited to those with a jewel count of zero or one. Therefore, the presence or absence of multiple jewels is the key differentiator when selecting between these two sub-headings.

As this is a leaf node within the HTS, there are no further subcategories for this specific classification. Classification at this level signifies that the goods meet all the preceding criteria: they are complete and assembled watch movements, electrically operated, and possess no jewels or only a single jewel. Understanding this specific jewel count is paramount for accurate customs declarations and duty assessment.
