Weights & Measures

The primary focus of the Weights and Measures program is to ensure that equity prevails in the marketplace and that commodities bought or sold are accurately weighed or measured and properly identified.

All weighing or measuring devices used in a commercial application are subject to inspection to ensure their accuracy. This includes the weight or measure of foods, non-food products, services, scanners, or commodities purchased in the State of Utah. We also respond to numerous consumer complaints dealing with violations of the weights and measures laws.

Most items purchased each day are sold by weight, measure, or count. Inspection of weighing and measuring devices for correctness and accuracy helps to protect both consumers and retailers from unfair business practices.

Package Inspection

All packages, cans, bottles, and containers that have a weight, measure, or count declaration are subject to inspection. Routine verification of the net contents of packages is done to facilitate value comparison and fair competition. Inspections are done at point-of-pack locations, storage warehouses, retail stores, and wholesale outlets.

Price Verification (Check out register)

All businesses that use a check-out register used at the final point of sale as a means for pricing for commercial sales are subject to inspection. Testing is done by randomly selecting items, recording the display price, then verifying the posted price matches the price charged at the checkout register. A passing score is 98% or above, meaning that only one of each 50 items selected is allowed to be incorrect.
