Division of Standards’ compliance officers conduct weights and measures inspections in about half of Massachusetts’ 351 cities and towns. Municipal Sealers of Weights and Measures (Sealers) conduct weights and measures inspections in the other half. The Division conducts weights and measures inspections in the Massachusetts municipalities with 5,000 or fewer residents pursuant to M.G.L. c. 98, § 35(a)(2); and municipalities with between 5,000 and 20,000 residents can choose to contract with the Division pursuant to M.G.L. Chapter 98, § 33A. Municipalities with more than 20,000 residents must appoint their own Sealer. Sealers can perform sealer duties in multiple communities.
Both the Division’s compliance officers and Sealers test, seal and inspect commercial weighing and measuring devices and check retail businesses for compliance with the unit pricing, item pricing, or price advertising laws. They also investigate consumer complaints about businesses.
Both the Division’s compliance officers and Sealers must pass a written and a practical examination administered by the Division. The Division oversees Sealers’ performance, pursuant to M.G.L. Chapter 98, § 36A.
