Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by aniline derivative structure
Aniline and derivatives in 2921 if amino function predominates over oxygen alcohol per numerical order.
If put up in retail packaging as hair color developer
Dyes in retail forms go to 3212; pure chemicals stay in Chapter 29.
If imported diluted in water or solvent beyond transport needs
Solutions not solely for safety/transport classify as preparations in 3824.
