Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of natural stone rather than synthetic diamond
Natural stone millstones and grindstones fall under a separate subheading in 6804.10, distinct from agglomerated synthetic abrasives.
If supplied with a metal framework or as a complete tool
Tools with mounted abrasive wheels, including diamond ones, shift to Chapter 82 for hand tools with working parts of agglomerated abrasives.
If imported as parts of grinding machines
Machine parts like diamond wheels for industrial grinders are classified under Chapter 84 for tools for working metal.

Import Tips & Compliance
• Verify abrasive composition certification to confirm synthetic diamond agglomeration per Chapter 68 notes
• Include material safety data sheets (MSDS) for diamond abrasives to avoid customs delays on hazardous classifications
• Label as 'without frameworks' to prevent misclassification under mounted tool headings
