S.C. Code Ann. § 12-22-960

The burden of proof that a machine, game, location controller, modem, or any part of a machine meets the required standards and requirements is the responsibility of the manufacturer or machine owner. The department may require the manufacturer or machine owner to obtain a certification from an approved laboratory indicating that the machine, game, location controller, modem, or any part of a machine meets the required standards and requirements. The cost of this certification is the responsibility of the manufacturer or machine owner. The department shall provide a list of approved laboratories. The department may also review a laboratory to determine if the laboratory should be added or removed from the department's list of approved laboratories. The department may contract with a testing laboratory to ensure and certify that a machine, game, location controller, modem, or any part of a machine meets the required standards and requirements. The department may also establish a state testing laboratory. Payment of the cost of testing by the laboratory is the responsibility of the manufacturer or machine owner. Approval of the machine by the department is prima facie evidence that the machine meets the required standards and requirements.
