Iowa runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Iowa — at a warehouse, farm, recycling yard, retail store, or truck stop — here is who regulates it, what the law requires, and exactly who to contact.
Who inspects commercial scales in Iowa?
State-run program: the IDALS Weights and Measures Bureau licenses and inspects all commercial weighing and measuring devices statewide; there are no county programs. Scale owners deal directly with the bureau at the Iowa Laboratory Facility in Ankeny, and IDALS-registered service agencies/servicepersons install and repair devices.
What Iowa requires of scale owners
Under Iowa Code 214, any person who uses or displays for use a commercial weighing device must secure an annual license from IDALS (calendar-year license, fee $9.00-$106.50 per device by capacity) and display it at the device location. Registered service agencies file Placed in Service Reports for scales, and state inspectors test/inspect licensed devices.
Getting a scale into service — 4 steps
- Buy a legal-for-trade (NTEP-certified) scale appropriate for your application and capacity.
- Confirm registration and licensing requirements with the Iowa Department of Agriculture and Land Stewardship (515-725-1492 (Weights & Measures Bureau); 515-281-5321 (IDALS main)) before the scale enters commercial use.
- Arrange compliant installation and calibration. Where required, placing-in-service must be done by a licensed or registered service company.
- Stay compliant. Pass required inspections, keep calibration current, retain service records.
