The holder of a nonresident wine vendor permit may sell, deliver, and ship unfortified and fortified wine in this State only to wholesalers, importers, and bottlers licensed under this Chapter, as authorized by the ABC laws. The unfortified and fortified wine must come to rest at the licensed premises of a wine wholesaler in this State before being resold to a retailer. A nonresident wine vendor permit may be issued to a winery, a wholesaler, an importer, or a bottler outside North Carolina who desires to sell, deliver, and ship unfortified and fortified wine into this State. The holder of a nonresident wine vendor permit may sell, deliver, and ship into this State only wine for which it is a primary American source of supply. To be considered a primary American source of supply, a nonresident wine vendor must establish that it has lawfully purchased the wine from the winery, or from an agent of the winery, and by written contract or otherwise has been authorized by the winery to distribute the wine to wholesalers in the United States.
