Kansas Scale Certification & Weights and Measures

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

State-run: KDA Weights and Measures inspectors test commercial weighing and measuring devices statewide (grocery, grain elevator, livestock barn scales, fuel meters, etc.). Day-to-day device certification relies on KDA-licensed private service companies and technicians, who place devices in service, remove state/city rejection tags, and perform the annual testing required by Kansas law; owners contact the division at 785-564-6681.

What Kansas requires of scale owners

Kansas does not register devices with owners; instead, Kansas law requires commercial devices to be tested annually by a KDA-licensed service company/technician (service company license $100, expires June 30; technicians must pass an exam). New or repaired devices must have an NTEP Certificate of Conformance and be placed in service by a licensed company, with the installation report (DI-701) and test report submitted to KDA within 10 days.

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 Kansas Department of Agriculture (785-564-6681) 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.
