Frequently Asked Questions

Regulatory & Compliance

  • In Oregon, any weighing device used to determine the price of a commodity or used in a commercial transaction must be "Legal for Trade." This requires the device to have a valid NTEP Certificate of Conformance (CC) and to be calibrated and sealed by a registered service person in accordance with NIST Handbook 44 standards.

  • While you can perform internal checks, Oregon law requires commercial scales to be metrologically sealed. Only a registered service person possesses the certified, NIST-traceable mass standards and the legal authority to break a state seal, adjust the device, re-seal it, and file the mandated Placed-In-Service Report (PISR).

  • A PISR must be filed with the Oregon Department of Agriculture (ODA) within 24 hours of:

    1. Installing a brand-new scale.

    2. Replacing an existing scale.

    3. Breaking a metrological seal to perform a calibration adjustment.

    4. Restoring a scale to service after it has been rejected (Red Tagged) by a state inspector.

  • Class III scales are typical retail scales used for larger quantities (e.g., deli meats or coffee beans). Class II scales are high-precision balances required for "Suitability" when weighing small increments, such as cannabis flower, concentrated extracts, or precious stones. Using a Class III scale for transactions under 1 gram is a common suitability violation that can lead to state audits.

The MSS Process

  • The Vault is our proprietary digital record-keeping system. Every scale we service receives a unique MSS QR code. When scanned by you—or a state inspector—it instantly displays the device's full calibration history, NIST-traceable certificates, and ODA filing status. This eliminates the need for paper logs and ensures you are always audit-ready.

  • A standard multi-point inspection and calibration for a single device typically takes 30 to 45 minutes. This includes environmental stabilization, shift testing, span calibration, and digital documentation.

  • To ensure the highest accuracy, please ensure the scale is located on a stable, level surface away from direct drafts (fans or AC vents). The scale should be powered on at least 30 minutes prior to the appointment to allow the internal components to reach thermal equilibrium.

Oregon Department of Agriculture (ODA) Audits

  • When an inspector finds a compliance issue, they issue an Official Notice and affix a tag to your device. You are required to take corrective action—usually recalibration by a registered technician—and notify the ODA within a specific timeframe (often 24 hours to 30 days). MSS provides priority response to these notices to ensure your business stays in good standing.

    • Red Tag (Stop Use Order): Your scale is legally out of service. You cannot use it for trade until it is corrected and the tag is cleared.

    • Blue Tag (Repair Order): You have a "grace period" (usually 30 days) to have the scale serviced. You can continue using it in the meantime, but if you miss the deadline, it will be upgraded to a Red Tag.

  • No. Removing or tampering with an official state tag is a violation of ORS 618 and can lead to significant civil penalties. Only an ODA inspector or an ODA-registered service person like the technicians at MSS can legally remove a tag after verifying the device meets NIST Handbook 44 standards.

  • Immediately. One of the primary benefits of hiring an MSS technician is that once we calibrate the scale and sign the back of the ODA tag (or file a PISR), you are legally authorized to resume commercial use the same minute we leave. You do not have to wait for the state inspector to return for a follow-up.

  • Generally, if it is a first-time violation and the scale is "Rejected" rather than found to be intentionally fraudulent, the ODA issues a repair or stop-use order. However, failing to resolve the issue within the mandated window or using a Red-Tagged device will trigger significant civil penalties.

  • The ODA aims to inspect every licensed commercial device in Oregon annually. However, audits are often triggered by consumer complaints, licensing renewals, or "blitz" inspections in specific neighborhoods. Proactive quarterly calibration is the only way to ensure you are ready for a surprise visit.
