Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as complete watch movements
Quartz crystals assembled into full watch movements with other timing components shift to Chapter 91 timepieces.
If classified as photosensitive semiconductor device
Misclassification occurs if the crystal has optoelectronic properties, but standard quartz timing crystals do not.
If as parts of computers when imported in bulk for assembly
Bulk assemblies of electronic components for computers may fall under data processing parts if not specifically mounted crystals.
