Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by carboxamide function
Carboxamide-function compounds take precedence in heading 2924 over general oxygen-function amino in 2922 per numerical order rule.
If for bulk medicinal preparations
Medicinal preparations in dosage form or bulk actives ready for formulation go to Chapter 30.
If ether function dominates without amino group
Aromatic ethers without nitrogen functions classify under heading 2909.
