Texas Scale Certification & Weights and Measures

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

State-run: TDA field staff inspect commercial devices statewide. There is no county sealer system — owners deal directly with TDA.

What Texas requires of scale owners

Commercial scales must be registered with TDA annually (form RWM 700 or the TAP portal at tap.texasagriculture.gov), and each device must be placed into service by a licensed technician employed by a TDA-licensed service company.

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 Texas Department of Agriculture ((512) 463-7698) 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.
