S.C. Code Ann. § 39-31-50: Clean rice is not subject to rinsing test for bulk rice.

Each pound of rice shall be sufficiently clean so that rinsing before cooking is unnecessary, according to the judgment of the Commissioner. Rice meeting this standard of cleanliness and in packages of less than fifty pounds is permitted but not required to meet the rinsing test described in Section 39-31-40 for bulk rice. Rice not meeting this standard of cleanliness shall be adjudged to be bulk rice and subject to such rinsing test.
