Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing a heterocyclic ring structure
Heterocyclic compounds with nitrogen hetero-atom are classified in heading 2933 rather than oxygen-function amino-compounds in 2922.
If imported as finished medicinal formulation
Formulated drugs ready for therapeutic use fall under Chapter 30, not chemical compounds of Chapter 29.
If primarily an amine without prominent oxygen function
Amine-function compounds lacking defined oxygen groups shift to heading 2921.
