Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If centerless type
Centerless grinders support workpieces without centers, classified in a distinct subheading from universal cylindrical.
If integrated for semiconductor testing
Some finishing apparatus for semiconductor devices may fall under Chapter 90 for testing equipment per statistical notes.
If imported as parts for semiconductor machines
Grinding machine parts or accessories are classified under heading 8466, not complete machines.
