If a grape wine has been flavored with plants or aromatic substances — as vermouth is — it belongs under 2205 regardless of alcohol content. Plain grape wine without such flavoring, including fortified wines like port or sherry, remains under 2204. The presence of botanical or aromatic flavoring is the decisive criterion.

Yes. Vermouth and other aromatized wines are regulated by the TTB as wine, and importers must hold a valid importer's basic permit. The foreign producer's formula may need TTB review to confirm that the flavoring agents and production method meet US standards before label approval is granted.
