This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for polishing rather than thickness calibration
Polishing/grinding machines have dedicated subheading 8464.20 vs. multi-function calibrators/polishers in 'other'.
If imported with granite/marble slabs as processing demonstration
Worked monumental stone with associated equipment classified primarily as stone articles.
If marketed as general surface filtering/planing equipment
General filtering or purifying machinery classified in 8421, not specific mineral working machine tools.
