Overview

Commercial weighing and measuring devices used in trade must meet Michigan and local standards for accuracy, calibration, and labeling. Operators should maintain calibration records and ensure devices are in good working order before inspection. The primary enforcement authority for statewide standards is the Michigan Department of Agriculture & Rural Development (Weights and Measures).[1]

Keep clear calibration records and takedown dates for easy inspection.
