Alabama Scale Certification & Weights and Measures

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

State-run: the Division's state inspectors inspect and regulate all weighing and measuring devices used commercially throughout Alabama. Scale owners deal directly with the Division's Montgomery office.

What Alabama requires of scale owners

Owners must register commercial devices with the state via the online Device Registration (new and renewal) system and use Registered Service Technicians for installation/repair work. The Division also licenses public weighmasters and issues fuel, brake fluid, and lubricating oil permits.

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 Alabama Department of Agriculture & Industries (334-240-7133 (main); 334-240-7135 (lab)) 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.
