Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for sharpening rather than shaping
Grinding machines for tool sharpening have distinct classification.
If integrated optical testing apparatus
Equipment combining processing with testing moves to Chapter 90.
If for soil preparation analogy, but semiconductor crystal growers
Wait, incorrect; actually for pure semiconductor crystal growers.
