UNSPSC 41116154: Particle counter and sizer quality controls and calibrators and standards

All quality controls and calibrators and standards utilized in automated particle enumeration and size distribution counters

UNSPSC 41116154 Particle counter and sizer quality controls and calibrators and standards is a Commodity code that does not align with the state and local opportunities recently posted under this classification. The recent solicitations — indoor air quality services, stormwater technology demonstration, and offender drug testing — involve asbestos and mold testing, environmental monitoring systems, and toxicology screening, none of which are particle counter calibration or quality-control services. The code shows little relevant recent activity in state and local procurement. Issuing bodies across the opportunities span county school districts, county environmental departments, and county corrections agencies, but none of the work being solicited reflects the scope nominally described by the UNSPSC code.

The geographic spread of the recent activity is concentrated in Florida and Texas: Pinellas County School District (Florida) posted an ITB for indoor air quality services with a response deadline of November 6, 2026; Escambia County (Florida) posted two consecutive RFPs for stormwater technology demonstration with August and September 2026 deadlines; and Collin County Community Supervision and Corrections Department (Texas) posted an RFP for drug testing services with a July 23, 2026 response date. The mismatch between the code's nominal description and the actual procurement activity suggests either a tagging error in the source data or that this code is being used inconsistently by state and local procurement offices. Business development professionals evaluating opportunities under this code should verify the actual scope of work directly from the solicitation notice rather than relying on the code classification alone.
