Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in topical cream/ointment form for retail sale
Finished medicaments with antibiotics in retail packaging shift to Chapter 30 per exclusions in Chapter 29 notes.
If considered a beta-lactam rather than aminoglycoside
Structural re-evaluation could place it in other natural antibiotic categories based on chapter note hierarchy.
If mixture of neomycin B and C isomers exceeding 'separate compound' purity
Chapter note (b) excludes complex isomer mixtures not meeting chemically defined compound criteria.
