Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for clocks rather than watches
Heading 9110 separates rough movements of watches from those of clocks; dimensional and end-use criteria determine classification.
If contains unassembled electronic timekeeping components
Chapter exclusions direct unassembled chapter 85 articles (electronics) away from heading 9110 to their material chapters.
If individual base metal components rather than assembled rough movement
Parts of general use in section XV (base metal) exclude from chapter 91; only assembled rough movements qualify here.
