Wine importer licensees and beer importer licensees shall not sell and deliver or ship any brand of beer or wine to wholesale licensees for the purpose of resale until such importer has also complied with the provisions of this section and Board regulations for each such brand. Any licensed importer, if not also the owner of the brand to be imported into the Commonwealth, shall provide to the Board written authorization from the brand owner entitling the importer to (i) sell and deliver or ship such brand into the Commonwealth and (ii) establish written agreements of a definite duration and within the meaning of the Wine Franchise Act (§ 4.1-400 et seq.) and the Beer Franchise Act (§ 4.1-500 et seq.), on behalf of the brand owner, as its authorized representative, with each wholesale licensee to whom the importer sells any brand of beer or wine owned by the brand owner. In addition, each such licensed importer shall file and maintain with the Board a current list of all wholesale licensees authorized by such importer, as the authorized representative of the brand owner, to distribute such brand within the Commonwealth.
