Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing additional nitrogen functions beyond simple amino-acid structure
Compounds with multiple nitrogen heterocyclic functions or other N-functions classify under 2924 per chapter note on last numerical order.
If imported as part of a heterocyclic compound mixture
Heterocyclic compounds with nitrogen hetero-atoms fall under 2933, taking precedence over amino-acid classification.
If it's a sugar derivative ester
Sugar esters and salts are excluded to heading 2940 per chapter exclusions.
