Can delta-Dodecalactone be labeled natural?

Nature makes delta-Dodecalactone, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial delta-Dodecalactone, same molecule. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.
