Who enforces weights and measures

The primary authority for weights and measures in Wisconsin is the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), which administers the state weights and measures program and inspects commercial measuring devices. Local jurisdictions may refer complaints or limited inspections to DATCP for enforcement and calibration verification.[1]

Penalties & Enforcement

Enforcement may include monetary fines, orders to repair or calibrate equipment, sealing or removing non-compliant devices from service, and referral to administrative or judicial action. Specific fine amounts, escalation steps, and exact non-monetary remedies are not specified on the cited DATCP page and should be confirmed with the enforcing office when you file a complaint.[1]

  • Fines: not specified on the cited page; contact DATCP or the City of Madison for case-specific information.
  • Escalation: first, repeat, and continuing offence procedures are not specified on the cited page.
  • Non-monetary sanctions: sealing of equipment, orders to repair/calibrate, and possible seizure or hold of devices are listed as enforcement actions in general program descriptions but exact procedures and thresholds are not specified on the cited page.
  • Enforcer: Wisconsin DATCP Weights and Measures program handles state enforcement; City of Madison may assist or refer complaints to DATCP.[1]
