Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If antisera, vaccines or toxins containing the alkaloid
Immunological products excluded from Chapter 29 per chapter note exclusion (e).
If other alkaloid salts not specifically ephedra-derived
Non-ephedra alkaloids use the residual 'other' subheading within 2939 structure.
If classified by saturated acyclic function if alkaloid structure ignored
Principal function rules could shift to earlier chapter headings.
