Artificial Flavor

The US rule turns on where something came from, not what it is. Vanillin made in a factory is artificial. The identical molecule pulled out of a vanilla bean is natural. An instrument cannot tell them apart, and neither can a taster.

That distinction matters commercially, because the manufactured version is usually far cheaper, available at consistent quality all year, and unaffected by a bad harvest somewhere.

Where artificial is still the norm

Where price is tight — mainstream candy, powdered drink mixes.

Where the process is brutal — hard candy cooked above 145 °C, extrusion, retort. The delicate natural components would be destroyed anyway.

Where there is no real thing to copy — blue raspberry, bubblegum and most cola flavors are invented, not extracted.

The real constraint is the label

A product containing an artificial flavor has to say so, and the claims you can make on the front of the pack narrow sharply.

So for a brand whose whole position depends on a clean ingredient list, the higher cost of a natural flavor is usually the cost of the claim — not the cost of better flavor.
