Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as naphthols without carboxylic acid emphasis
Naphthols classify in 2907 if phenol function dominates per numerical order in Chapter 29.
If containing additional alcohol functions
Other oxygen functions beyond phenol would move to subsequent 'other' carboxylic acid subheadings.
