Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the grinder is presented as a flat-surface grinding machine with a CNC control
Heading 8460 covers grinding machines for finishing metal or cermets, which may be more specific than the residual heading 8461.
If importing parts or accessories for the grinder separately
Parts for machine-tools of heading 8461 are classified under heading 8466.
