UNSPSC 41151528: Usp colorimetric standards

In this classification, this entry connotes a colorimetric standard that incorporates the USP Color Index.

UNSPSC 41151528 USP colorimetric standards is a Commodity code with minimal recent state and local procurement activity. The available opportunities show no purchases of colorimetric standards themselves. Instead, the code appears to have been applied to a mix of unrelated laboratory and testing equipment acquisitions, including an optical surface profilometer, airfield photometric testing services, drug discovery software, meter test boards, high-voltage test modules, sterilization equipment maintenance, atmospheric gas sensors, and spectrophotometers. None of these represent colorimetric standards or reference materials as the code nominally describes. The issuing bodies span diverse sectors—community colleges, airport authorities, universities, municipal utilities, state health departments, and county governments—with no pattern of repeat buyers under this code.

Geographic activity centers on Florida (Valencia College in Orlando, Lee County Port Authority, City of Tampa, City of Ocala, Kissimmee Utility Authority, Collier County, and Marion County's out-of-state comparator) and Texas (Jackson State University appearing twice for the same Schrodinger software sole-source, Texas A&M University System, Texas State University, and Texas DSHS). Colorado and Phoenix, Arizona each show one opportunity. The recent opportunities provide no clear evidence of state or local demand for colorimetric standards proper; the code's application appears misaligned with actual purchasing intent across the sample. Representatives include Valencia College's sole-source notice for an optical surface profilometer (October 2026, notice-of-intent format), Lee County Port Authority's RFQ for airfield photometric testing (October 2026, quote due October 29), and the City of Ocala's RFP for a three-phase meter test board (September 2026, proposals due April 30, 2026—a date conflict suggesting data quality issues). No recent opportunities in this sample directly solicit colorimetric standards, reference materials, or calibration solutions.
