UNSPSC 51442200: Gadolinium-based medical imaging agents, media, and tracers

This classification denotes a variety of compounds and preparations that are sensitive to frequencies or rays common in nuclear medicine that empower practitioners to differentiate between cell or tissue types, or to bring to focus one cell or tissue type over another, and to thus examine internal body parts or systems, typically for diagnostic purposes, and which are based in part or whole on the chemical element that bears symbol Gd and atomic number 64, called Gadolinium, and isotopes thereof, thus the term GADOLINIUM-BASED MEDICAL IMAGING AGENTS, MEDIA, AND TRACERS.

UNSPSC 51442200 Gadolinium-based medical imaging agents, media, and tracers is a Class code that in practice spans a narrower scope than its nominal title suggests. State and local solicitations under this code focus on radiologic and X-ray equipment procurement, installation, and maintenance services rather than on gadolinium contrast agents themselves. The issuing bodies are county governments and county-affiliated entities—Maricopa County, Escambia County Correction, and Broward County Aviation Department are recent buyers. The scope of work includes radiologic equipment and installation at educational facilities, extended warranty coverage for specialized X-ray machines, and maintenance and repair services for proprietary X-ray inspection systems. One outlier in the recent set—Pasco County's solicitation for copper sulfate chemicals—does not align with the code's radiologic-equipment focus and appears to be a classification mismatch.

Recent activity is concentrated in Florida and Arizona. Maricopa County issued an IFB (IFB362910) on October 1, 2026, for radiologic equipment and installation services at three colleges with a response date of October 22, 2026. Escambia County Correction posted a sole-source procurement (SSCORALM2526005) on August 12, 2026, for an extended warranty on specified X-Ray machines, due August 19, 2026. Broward County Aviation Department issued an RFI (BLD2132311F1) posted June 25, 2026, to determine whether maintenance services for Rapiscan X-ray inspection systems are available from vendors other than the sole-source provider, with responses due July 28, 2026. The mix of notice types—IFB, sole-source warranty procurement, and RFI challenging sole-source designation—reflects both new equipment acquisition and ongoing support for installed base systems.
