S.C. Code § 12-28-1530
The supplier and the terminal operator may rely for all purposes of this chapter on the representation by the transporter, the shipper, or the shipper's agent as the shipper's intended state of destination and user fee-exempt use. The shipper, the importer, the transporter, the shipper's agent, and a purchaser, not the supplier or terminal operator, are jointly liable for any user fee otherwise due to the State as a result of a diversion of the motor fuel subject to the user fee from the represented destination state. A terminal operator may rely on the representation of a licensed supplier with respect to the supplier's obligation to collect user fees and the related shipping paper representation to be shown on the shipping paper as provided by Section 12-28-1540(A).
