Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If impure or containing stabilizers
Impurities or added stabilizers may classify it under the general 'other' aromatic polyamines subheading rather than the specific pure compound.
If pre-reacted into azo dye intermediate
When chemically modified for direct use as synthetic coloring matter, it shifts to Chapter 32 headings for dyes.
If dissolved in solvent for transport
Solutions in solvents for safety/transport, per chapter note (e), may fall under mixtures if not qualifying as pure compound.
