Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the particles are cut into discs, wafers, or similar forms for electronics
Doped chemical elements in such forms are excluded from Chapter 28 by Note 8.
If the particles are formulated into antimicrobial coatings for retail sale
Products put up for retail sale as biocides fall under Chapter 38.
