Tennessee runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Tennessee — 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 Tennessee?
State-run: TDA's Weights and Measures Section inspectors test commercial measuring devices statewide (fuel pumps, scales, LPG meters) and perform package check-weighing and UPC price verification. Owners contact the section at weights.measures@tn.gov / 615-837-5109.
What Tennessee requires of scale owners
Tennessee publishes no device-registration program for scale owners; under Tenn. Code Ann. 47-26-907 all commercial devices must meet NIST Handbook 44/130 technical requirements and NTEP type evaluation. Persons who service/repair devices must hold Service Person/Service Agency licenses and file a Placed In Service Report; public weighing requires a Certified Public Weigher or Weighmaster license.
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 Tennessee Department of Agriculture ((615) 837-5109; toll-free 1-800-628-2631; metrology lab (615) 837-5159) 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.
