Can Benzoin be labeled natural?

Benzoin occurs in nature, so the label depends on the route: benzoin won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized benzoin is artificial. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic benzoin identical-to-natural.

Natural or artificial, by process
European Union and UK
Natural only from natural material
Mercosur and Mexico
Natural or identical-to-natural

How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.
