Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chloride instead of bromide
Chloride salts of ammonium fall under 2827.41, as headings 2826-2842 distinguish by halide type.
If prepared as a double salt with another metal
Chapter note specifies double or complex salts classify in 2842, not simple single-metal bromides.
If ammoniated fertilizer grade
Note 2 excludes Chapter 31 products like ammonium salts used as fertilizers from Chapter 28.
