Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If using cubic boron nitride (CBN) instead of diamond
CBN agglomerated abrasives fall under a separate subheading in the same grinding wheel category.
If classified as a tool rather than a standalone grinding wheel
When marketed as bandsaw sharpening tools with diamond segments, it shifts to Chapter 82 for saw blades.
If made from natural millstone or similar natural stone
Natural stone-based grindstones are distinguished from synthetic diamond agglomerates in the heading.

Import Tips & Compliance
• Verify segment composition meets 'agglomerated with metal' criteria via supplier specs to avoid reclassification
• Include material safety data sheets (MSDS) for diamond abrasives in documentation for customs clearance
• Ensure plates are confirmed as steel; non-steel backing may still qualify but note in entry summary
