Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specialized part for semiconductor wafer prep machines
Dedicated machine parts for semiconductor processing go to 8466, excluding hand-held tools.
If primarily a grinding wheel without pneumatic tool
Millstones and grinding wheels are classified by material in Chapter 68 if not powered tools.
If for medical or lab grinding, not semiconductor
Instruments for semiconductor manufacturing stay in 84/90; non-semicon use may shift to lab equipment.
