S.C. Code Ann. § 38-85-60: Premiums.

If an insurer charges debtors the same premium for the new coverage that they were paying for the old coverage, and, as a result, insured debtors of a financial institution are charged different premium rates for the same coverage, the rate differences do not constitute unfair discrimination under Sections 38-55-50 and 38-57-120, so long as all the applicable requirements of this chapter are met.
