Utah Scale Certification & Weights and Measures

Utah runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Utah — 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 Utah?

State-run program: UDAF Weights and Measures inspectors test all commercially used weighing and measuring devices statewide, plus packages, price scanners and motor fuel quality; there are no county W&M programs. Scale owners contact the UDAF program in Taylorsville.

What Utah requires of scale owners

Businesses must register their establishment with UDAF and pay annual per-device registration fees based on devices in service (e.g., $50 per small scale up to 1,000 lb, $200 per large scale over 1,000 lb and $25 per checkout register on the establishment-registration page; the July 2026 application form lists $225 for large scales); devices are then subject to state inspection. UDAF also publishes a Registered Service Person application and Placed-in-Service Report forms for scale service companies/technicians.

Getting a scale into service — 4 steps

1. Buy a legal-for-trade (NTEP-certified) scale appropriate for your application and capacity.
2. Confirm registration and licensing requirements with the Utah Department of Agriculture and Food at (801) 982-2261 before the scale enters commercial use.
3. Arrange compliant installation and calibration. Where required, placing-in-service must be done by a licensed or registered service company.
4. Stay compliant. Pass required inspections, keep calibration current, retain service records.
