Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for grinding or polishing gears
Grinding/polishing work holders fall under separate subheading 8466.30 for finishing operations, not primary cutting.
If for semiconductor wafer processing machines
Jigs for machines processing semiconductor wafers (e.g., grinders under statistical note) classify in 8466.94 for semiconductor-specific parts.
If designed as a complete gear positioning fixture with gearing
Fixtures incorporating gears or gearing mechanisms shift to Chapter 84 heading 8484 for gaskets and similar articles.
