Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by carboxamide function rather than lactam
Carboxamide-acid compounds may shift to Chapter 29 heading 2924 if lactam ring not principal characteristic.
If for non-aromatic lactams
Lacking aromatic modification, it would classify under other non-aromatic lactams in 2933.59.
