North Carolina General Statutes Chapter 81A. Weights and Measures Act of 1975 § 81A-53. Certificates of weight

All public weighmasters shall issue certificates of weight, measure, count, reading or recording on forms approved by the Commissioner and shall enforce the provisions of this Chapter and all rules and regulations promulgated thereunder without compensation from the State. Each certificate issued shall indicate the date on which a product is weighed, counted, read or recorded. A certificate issued by a public weighmaster shall be considered the accurate weight of a product at the time the product is put into the natural channels of trade, with the qualification that reasonable variations or tolerances shall be permitted as established by rules and regulations enacted pursuant to this Chapter. If any person questions the accuracy of the weight of any product for which a certificate has been issued, a complaint shall be made to the public weighmaster who issued the certificate or to the Commissioner before the product is moved from the city, town or community where the certificate was issued. The product shall be reweighed by the public weighmaster issuing the certificate or by the Commissioner, if the product is kept in accordance with G.S. 81A-58. If, upon reweighing, a difference in excess of the tolerance allowed by the Chapter is found in the original weight, the cost of reweighing shall be borne by the public weighmaster responsible for issuing the faulty certificate. Otherwise, the cost shall be borne by the complainant.
