S.C. Code Ann. § 39-17-50

After investigation and from time to time as may be practicable and advisable, the division of markets of the extension service may establish and promulgate standards of open and closed receptacles for farm products and standards for the grade and other classification of such products by which their quantity, quality and value may be determined and may prescribe and promulgate rules and regulations governing the marks, brands and labels which may be required for receptacles for farm products for the purpose of showing the name and address of the producer or packer and the quantity, nature and quality of the product, or any of them, and for the purpose of preventing deception in reference thereto and establishing a State brand for any farm product produced in the State. Any standard for any farm product or receptacle therefor or any requirement for marketing receptacles for farm products established under authority of the Congress of the United States shall forthwith, as far as applicable, be established or prescribed and promulgated as the official standard of requirement in this State. No standard established or requirement for marketing prescribed under this article shall become effective until the expiration of thirty days after it shall have been promulgated.
