III. The commissioner of agriculture, markets, and food, in consultation with the division of forests and lands and the University of New Hampshire cooperative extension, shall establish standards for mill graders who will stamp or certify native lumber. The commissioner shall issue a written permit to each mill grader who has received training and who demonstrates by examination or other procedure prescribed by the commissioner in rulemaking, competence, and ability to grade and certify or stamp native lumber in accordance with paragraph II of this section. No lumber shall be sold as certified or stamped native lumber unless it is accompanied by a certificate signed by a grader holding a valid permit.
