Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically treated or synthetic
Elemental boron or treated diamonds may shift to Chapter 28 if qualifying as chemical products.
If sold as finished grinding or polishing wheels
Completed abrasive articles containing diamonds are classified in 6804.22.
If semi-manufactured (e.g., sawn or shaped)
Worked but not set diamonds, like sawn boart, go to heading 7103.
