Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If esterified with polyol rather than simple ethyl alcohol
Complex esters may fall under salts/esters subheading based on alcohol complexity
If containing heterocyclic ring structure
Chapter notes exclude heterocyclic compounds from basic amino acid headings
If US goods returned after esterification abroad
Articles exported for processing qualify for duty-free entry under 9802
