✓ Verified from official sources — July 11, 2026

In New York, day-to-day scale inspection is handled at the county or local level, with the state agency setting standards and providing oversight. If you operate a commercial scale in New York — 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 New York?

60 county and city Weights and Measures departments perform device inspections and take complaints (directory: agriculture.ny.gov/weights-and-measures/weights-measures-departments). The state division tests specialized classes (LP gas meters, large vehicle scales, terminal rack meters) and runs the metrology lab.

What New York requires of scale owners

Commercial devices must be type-approved (NTEP Certificate of Conformance per NIST Handbook 44) before use in New York, and are inspected/sealed by the local county or city W&M department.

Devices used to buy or sell by weight must comply with NIST Handbook 44 — in practice this means an NTEP-certified, legal-for-trade scale. Confirm requirements for your device class with the office listed here.

Getting a scale into service — 4 steps

  1. Buy a legal-for-trade (NTEP-certified) scale appropriate for your application and capacity.
  2. Contact your county or local Weights & Measures office to confirm registration, fees, and inspection scheduling (state program: New York State Department of Agriculture and Markets, (518) 457-3146).
  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.
