S.C. Code Ann. § 38-27-990: Interstate priorities.

(a) In a liquidation proceeding in this State involving one or more reciprocal states, the order of distribution of the domiciliary state controls as to all claims of residents of this State and reciprocal states. All claims of residents of reciprocal states are given equal priority of payment from general assets regardless of where the assets are located.

(b) The owner of a secured claim against an insurer for which a liquidator has been appointed in this State or any other state may surrender his security and file his claim as a general creditor, or the claim may be discharged by resort to the security in accordance with SECTION 38-27-600, in which case the deficiency, if any, is treated as a claim against the general assets of the insurer on the same basis as claims of unsecured creditors.
