Division of Standards
The Commonwealth's weights & measures agency — enforcing accuracy in every transaction since 1907.
The Division of Standards is a state regulatory agency under the Office of Consumer Affairs and Business Regulation (OCABR), established by M.G.L. c. 24A § 5. We are the Commonwealth's weights-and-measures agency, responsible for ensuring the accuracy of weighing and measuring devices used in the sale of food, fuels, and other products.
In addition to weights and measures, the Division issues nine major license and permit types covering auctioneers, hawkers and peddlers, transient vendors, motor fuel and oil retailers, auto body and glass shops, anti-freeze sellers, scanner-waiver grocers, and event promoters. In 2023, DOS issued or renewed 9,895 licenses, collected $3.5M for the General Fund, and responded to 640 consumer complaints.
DOS also operates the state's NIST-certified Echelon III Metrology Laboratory in Ashland, certifies municipal sealers, and oversees the 188-sealer municipal network that inspects more than 200,000 commercial devices every year.
