Can Isoamyl salicylate be labeled natural?

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