What We Do

Certification: Weights and Measures & Alternative Pricing Systems (APS)

Certification of Weighing and Measuring Devices:  All devices used for weighing or measuring (i.e., scales and gas pumps), where products are sold directly to consumers, must be certified and sealed annually by the City of Chicago. A certification inspection performed by the Department of Business Affairs and Consumer Protection (BACP) will test the accuracy of your device.

Alternative Pricing System (APS) - Alternative Pricing System, or APS, is a system other than individual price marking that is designed to inform consumers of the price of particular products and exempts the retailer from the requirement of individual price marking. Explore frequently asked questions, familiarize yourself with a blank inspection sheet, and read the governing rules and regulations.
