Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as an aniline salt rather than base
Aromatic amine salts are provided for separately in 2921.42.
If containing heterocyclic ring structure
Heterocyclic compounds with nitrogen are classified in heading 2933.
If primarily aromatic alcohol rather than amine-function
Principal function determines classification; alcohol-function takes precedence.
