Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of heterogeneous dye preparation for retail
Dye preparations containing this compound fall under Chapter 29 heading 2933 if not purely chemically defined.
If further processed into synthetic organic coloring matter
Once converted to finished pigment or dye, it shifts to Chapter 32 for synthetic coloring matter.
If classified by cyclic hydrocarbon structure ignoring amino-quinone function
Erroneous classification as substituted cyclic alcohols/phenols; amino-quinone takes precedence per chapter notes.
