Can Vanillyl butyl ether be labeled natural?

Vanillyl butyl ether occurs in nature, so the label depends on the route: vanillyl butyl ether won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized vanillyl butyl ether is artificial. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
