Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sawn but then polished or shaped for specific industrial tools
Any polishing moves classification from simply sawn to 'worked' diamonds in 7102.29.
If already manufactured into millstones or grinding wheels
Finished abrasive products containing diamonds are classified by function in Chapter 68.
If processed into interchangeable tool tips or inserts
Diamond tool inserts ready for machinery use fall under tools heading 8207.

Import Tips & Compliance
• Include processing certificates showing only simple sawing without further faceting or polishing
• Declare exact dimensions and weight; slabs over certain sizes may trigger different statistical suffixes
• Pair with end-use statements for manufacturers to avoid reclassification as gem material
