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 recent state and local contract opportunities posted under it. The two most recent opportunities—Escambia County's Bio-Health Pod Systems stormwater technology demonstration (RFP PD2526098, due August 14, 2026) and Collin County's offender specimen collection and drug testing services (RFP 2026-327, due July 23, 2026)—involve stormwater management equipment deployment and drug-testing laboratory services, neither of which relates to particle-counting instrumentation, quality-control standards, or calibration services. The mismatch suggests either a coding error in the source opportunities or a divergence between the code's nominal scope and how state and local procurement offices are tagging opportunities in practice.

Without recent opportunities that actually address particle counters, sizing instruments, or calibration standards for state and local buyers, this code shows little actionable recent activity. The geographic spread across Florida and Texas in the posted opportunities does not reflect procurement demand under the code's intended scope. Business development professionals should verify whether state and local purchasing offices in their target markets are posting particle-counter or calibration-services opportunities under different codes before committing resources to pursue this classification.
