9108.20.40.00 - Having over 17 jewels 🖩

This HTS category, 9108.20.40.00, specifically covers assembled watch movements that utilize automatic winding mechanisms and possess more than seventeen jewels. The presence of over 17 jewels is a key physical characteristic that distinguishes these movements from others within the broader category of complete and assembled watch movements. This classification is relevant for timepieces where the mainspring is automatically wound by the motion of the wearer's wrist, eliminating the need for manual winding.

Within the scope of "Watch movements, complete and assembled: With automatic winding," this specific subheading differentiates itself from its sibling, 9108.20.80.00 ("Other"). The sibling category would encompass automatic winding watch movements with seventeen jewels or fewer, or those with different defining characteristics not explicitly covered here. Therefore, the decisive factor for classification under 9108.20.40.00 is the combined criteria of automatic winding and the presence of over seventeen jewels.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific classification. All goods meeting the criteria of an automatically wound watch movement with more than seventeen jewels will terminate at this HTS code. The classification relies entirely on the physical attributes of the movement itself, particularly its winding mechanism and jewel count.
