Mississippi runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Mississippi — 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 Mississippi?
State-run: MDAC Weights and Measures Division inspectors make routine inspections of all types of commercial weighing devices statewide, plus package and price-verification inspections. Owners contact the Division's Jackson office.
What Mississippi requires of scale owners
Commercial weighing devices must be NTEP type-evaluated with an NCWM Certificate of Conformance or they may not be used commercially in Mississippi. Scale installation requires a Scale Installation Permit, and companies/repairmen that install, test, or repair scales must be licensed by MDAC (service work is documented via the online Service Report Form); no general annual device registration by owners is published.
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 Mississippi Department of Agriculture and Commerce at (601) 359-1149 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.
