Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as niacin (nicotinic acid) instead of niacinamide
Niacin and niacinamide have separate 10-digit statistical suffixes within the same heading; mislabeling the amide form as acid changes the specific code.
If dissolved in solvent for retail cosmetic formulations
Solutions exceeding Chapter 29 note (e) limits for transport/safety become mixtures of Ch.38, not pure unmixed vitamins.
If pre-formulated into finished tablets or capsules
Vitamin products put up in dosage forms for retail sale shift from bulk chemicals (Ch.29) to medicaments (Ch.30).
