9108.90.20.00 - Other

This HTS category, 9108.90.20.00, encompasses "Other" complete and assembled watch movements that do not fall under the specific criterion of the sibling category, 9108.90.10.00. The primary distinguishing factor for inclusion here is the absence of specific size limitations. Therefore, this classification applies to watch movements that are fully assembled, functional, and designed for use in watches, but whose overall diameter measures greater than 33.8 mm.

This category serves as a residual classification for watch movements meeting the general criteria of Chapter 91, but which do not fit the more narrowly defined sibling. The key criterion for differentiation lies in the physical dimension of the movement. If a complete and assembled watch movement is larger than 33.8 mm in diameter, it would be classified under this "Other" designation, provided it meets all other general requirements for watch movements.

As this is a leaf node within the HTS structure, there are no further subcategories for watch movements within this specific code. Classification decisions under 9108.90.20.00 will therefore rely on accurately determining that the movement is complete and assembled, has no jewels or only one jewel, and does not meet the size specification of the preceding sibling code.
