Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If holding flux with zinc chloride additives
Commercial galvanizing fluxes are mixtures classified in 3810 as metal fluxes, not pure ammonium chloride.
If blended with other metal chlorides
Other chlorides of metals (not ammonium) fall in 2827.39; mixtures may shift based on principal component.
If sold as prepared soldering flux
Prepared fluxes for soldering/metal joining containing NH4Cl are in 3824 as chemical preparations.
