Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not numerically controlled
Non-CNC boule grinders fall under the 'other' non-numerically controlled category.
If classified as general semiconductor manufacturing machine
If boule shaping not deemed 'grinding with abrasives,' it may go to semiconductor machines NESOI.
If integrated with inline testing functions
Equipment with primary testing capabilities for semiconductor materials shifts to Chapter 90.
