Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alcohol derivative form
Azo-compounds with added alcohol functions may classify under Chapter 29 alcohol priority headings per classification notes.
If micronized with wetting agents
Processed ADCA with dispersion additives becomes chemical preparation rather than pure compound.
If modified for dye intermediate
Heterocyclic derivatives of ADCA for dye production shift to Chapter 29 heterocyclic compounds.
