Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as vitamin B1 (thiamine) derivative by error
Different B-vitamin derivatives have distinct headings; Chapter 29 prioritizes last numerical order but requires correct chemical identification.
If chemically modified as sugar ester/acetal derivative
Sugar-modified niacinamide derivatives move to heading 2940 per Chapter notes, outside unmixed vitamins.
If mixed with stabilizers exceeding Chapter note (f) limits
Additives beyond preservation/transport render it a chemical preparation of Ch.38 rather than pure vitamin.
