Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed complete welding flux
Pickling preparations and fluxes are in 3810.
If confused with sodium chlorate fluxes
Chlorates and perchlorates are separate in 2829.
If borate-based flux additive
Borosilicate fluxes would be boron compounds.
