Oklahoma runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Oklahoma — 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 Oklahoma?
State-run program: ODAFF Consumer Protection Services field inspectors and dedicated weights and measures scale technicians inspect commercial weighing and measuring devices statewide; there are no county programs. Owners contact the W&M program administrator at ODAFF in Oklahoma City.
What Oklahoma requires of scale owners
Commercial devices must be installed, serviced and calibrated by an ODAFF-licensed service agency employing licensed device service technicians, which files a Placing In-Service Report with ODAFF (scales@ag.ok.gov); state inspectors then verify devices perform within acceptable tolerances under the Oklahoma Weights and Measures Law and the Service Technician and Service Agency Act.
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 Oklahoma Department of Agriculture, Food and Forestry at (405) 521-3864 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.
