Nevada runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Nevada — 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 Nevada?
State-run program: the NDA Division of Measurement Standards tests and inspects all legal-for-trade commercial devices throughout Nevada and also runs fuel sampling, public weighmaster, package inspection, price verification and the Registered Service Agency program; there are no county W&M offices. Scale owners contact the Sparks office.
What Nevada requires of scale owners
Commercial scales must be legal for trade and pass NDA testing/inspection; companies that install, service or repair devices must register annually with NDA as Registered Service Agencies under NAC/NRS 581 ($100 per agency plus $20 per serviceman) and file a Placed in Service Report (form DA-WM 101) when a device is installed or returned to service.
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 Nevada Department of Agriculture ((775) 353-3782) 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.
