S.C. Code Regs. § 5-263
Dealers or other commercial secondary processors purchasing rice non-enriched shall prepare an approved certificate, in triplicate. This certificate must be approved by the Commissioner--one copy to be furnished his office, the other copy to be retained by the purchaser, and the original to be furnished the supplier of non-enriched rice. The certificate may be in the form of a blanket certificate to cover all purchases from each supplier for an indefinite period of time, or a separate certificate may be furnished with each purchase order. The following form of certificate is suggested:
"This is to certify that the rice purchased by me, or us, from you, is to be used solely in the production of enriched rice, or for shipment out of the State of South Carolina, or in the manufacture of legitimate products not covered by the provisions of the Rice Enrichment Act. This certificate is to remain in force until written notice of its cancellation."
