S.C. Code § 61-6-2900
Alcoholic liquors must be shipped or moved from a point outside this State to a point inside the State only by railroad companies, steamship companies, express companies, or truck companies authorized to do business in the State as common carriers by the Department of Public Safety, by wholesalers licensed by the department, or by registered producers in their own trucks. Alcoholic liquors must be shipped or moved only to the warehouse of the food manufacturer licensed pursuant to Section 61-6-710, or the registered producer in care of the producer representative who is registered to handle the property of the registered producer originating the shipment. The shipment of alcoholic liquors must be either stored in the warehouse of the food manufacturer licensed pursuant to Section 61-1-710 or in a licensed warehouse of the registered producer or, after delivery to the producer representative is complete, may then be shipped to a licensed wholesaler by common carriers described in this section, by wholesalers licensed by the department or by registered producers in their own trucks. Shipments of alcoholic liquors from a licensed producer's warehouse to a licensed South Carolina wholesaler may be made in a vehicle owned or operated by the wholesaler. If alcoholic liquors are stored in the warehouse of a registered producer, or after delivery to the producer representative is complete, they may be shipped to a licensed wholesaler or to a point outside this State. Before any shipment or transfer, the food manufacturer or producer representative, as appropriate, must apply to the department, on forms prescribed by the department, for permission to ship or transfer the alcoholic liquors, and the food manufacturer or producer representative must have received a certificate of approval of the shipment or transfer.
