Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If completely unworked without any bruting

If further worked beyond simple bruting, like faceted
Diamonds that are cut, polished, or faceted are classified in 7102.39 for worked nonindustrial diamonds.
If intended for industrial cutting or grinding tools
Nonindustrial diamonds become synthetic or industrial under Chapter 71 if end-use shifts to industrial applications.
