Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If doped or cut into wafers/discs for semiconductors
Chemically doped or processed forms for electronics shift to 3818 per Chapter note on silicon/selenium analogs.
If in dispersion for photoresist stripping
Aqueous dispersions or mixtures classify as chemical preparations, not pure salts.
If simple aluminum potassium sulfate (alum)
Alums are non-peroxo sulfates in 2833.22; peroxo structure defines 2833.40.
