Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If segments are impregnated with abrasive other than diamond
Non-diamond agglomerated abrasives like silicon carbide use a different subheading.
If imported as part of machinery like a floor grinder
Parts for other machinery may fall under Chapter 84 if not standalone abrasives.
If for interchangeable tool bits with diamond segments
Interchangeable abrasive tools for hand tools are classified in Chapter 82.

Import Tips & Compliance
• Label as 'polishing only' to distinguish from cutting wheels and prevent misclassification under cutting tool codes
• Provide grinding RPM specifications in invoices to confirm non-cutting use per HTS description
• Check for anti-dumping duties on Chinese-origin diamond abrasives; origin certificates are essential
