Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for amide-function compounds if lactam ring ignored
Amides classification applies if not recognized as heterocyclic lactam per Chapter 29 hierarchy.
If blended with stabilizers exceeding Chapter note g limits
Mixtures with added stabilizers for transport may fall under chemical preparations if not 'normal' per notes.
If in aqueous solution for safety transport
Chapter note (d) allows water-dissolved pure compounds to stay in Chapter 29, but high concentration might shift.
