Device & Commodity Program

Who We Are and What We Do

The program performs annual inspections of all commercial weighing devices throughout the state to ensure scales are weighing accurately. Inspectors also perform package inspections and price verifications to verify that items ring up accurately at the register and weigh the amount stated on the packaging. This program is also responsible for enforcing the Missouri Egg Law and the Missouri Unfair Milk Sales Practices Act.

Scale Inspections and Testing

Small-Scale Inspectors test scales with a capacity up to 1,000 pounds and are typically the type of scales found at grocery stores, farmers markets, postal/shipping businesses and other retail locations that sell by weight under 1,000 pounds.

Large-Scale Inspectors test scales with a capacity of 1,000 pounds or greater. These types of scales are typically found at grain elevators, rock quarries, livestock markets, manufacturing facilities and other retail locations that sell by weight over 1,000 pounds

Package Inspection, Price Verification, Grain Moisture Meter Testing
