Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for non-butyl substituted dinitrophenols
Heading specificity limits to butylphenols; others classify as general dinitro- or polynitro-phenols.
If mixed with solvents or stabilizers beyond chapter allowances
Solutions exceeding 'normal transport' criteria per note 2(e) shift to mixtures in Chapter 38.
