Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed for general industrial sawing
Circular saw blades not principally for semiconductor machines classify as general metalworking tools.
If predominantly diamond but lacking machine specificity
Millstones and grinding wheels of agglomerated diamonds shift if not proven as 8472 accessory.
If sold as replacement for multiple machine types
Non-specific parts for various machinery fall under machines and mechanical appliances having individual functions.
