S.C. Code Ann. § 39-25-90: Definitions and standards adopted under Federal act.

(a) Definitions and standards of identity, quality and fill of container and their amendments, now or hereafter adopted under authority of the Federal act are the definitions and standards of identity, quality and fill of container in this State. However, when in his judgment such action will promote honesty and fair dealing in the interest of consumers, the Commissioner may promulgate regulations establishing definitions and standards of identity, quality and fill of container for foods where no Federal regulations exist. In addition, the Commissioner may promulgate amendments to any Federal or State regulations which set definitions and standards of identity, and may promulgate amendments to any Federal or State regulations which set standards of quality and fill of container for foods.

(b) Temporary permits now or hereafter granted for interstate shipment of experimental packs of food varying from the requirements of Federal definitions and standards of identity are automatically effective in this State under the conditions provided in such permits. In addition, the Commissioner may issue additional permits where they are necessary to the completion or conclusiveness of an otherwise adequate investigation and where the interest of consumers is safeguarded. Such permits are subject to the terms and conditions the Commissioner may prescribe by regulation.
