Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of millstone grit or similar natural abrasive aggregate
Millstones and grindstones specifically of millstone grit fall under the earlier subheading in the same chapter.
If composed of agglomerated natural abrasives
Products bound with binders like resin change from pure natural stone to agglomerated, altering the subheading.
If mounted on a tool shank for power hand tools
When assembled as a complete tool part rather than a standalone wheel, it classifies under hand tools of Chapter 82.

Import Tips & Compliance
• Verify the stone is natural (e.g
• sandstone or quartzite) via geological certification to avoid reclassification as agglomerated abrasives
• Provide mill test reports confirming no synthetic binders, as Chapter 68 excludes coated or impregnated materials
