Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crucibles or laboratory ware
Worked synthetic diamond articles for lab use may classify under Chapter 69 as ceramic-like products.
If when integrated into electrical components
Diamond films as insulating supports for electrical apparatus shift to Chapter 85.
If for gemological dust or powder
Dust and powder of natural/synthetic diamonds classify under 7105, separate from worked industrial forms.
