UNSPSC 51442006: Sulfur hexafluoride

This classification denotes a contrast agent with the molecular formula F6S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier WS7LR3I1D6, chemically known as sulfur fluoride (sf6), (oc-6-11)- but more generally known as sulfur hexafluoride, which bears U.S. National Institutes of Health Compound Identifier 17358. The European Medicines Agency schedules Sulfur hexafluoride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15925MIG.

The World Health Organization schedules sulfur hexafluoride in its Anatomical Therapeutic Chemical (ATC) Classification. Most nations schedule Sulfur hexafluoride under HS 28111990. SMILES: S(F)(F)(F)(F)(F)F.

UNSPSC 51442006 Sulfur hexafluoride is a Commodity code that in recent state and local practice covers X-ray equipment maintenance services, extended warranties, and diagnostic imaging system support rather than the chemical gas the code nominally describes. State and local buyers under this code include county correction departments, county aviation authorities, county educational systems, and regional water utilities. The work involves procuring specialized maintenance service plans and extended warranty coverage for proprietary X-ray inspection and radiologic equipment, characterized as highly specialized technical support for complex imaging systems that often carry sole-source or sole-brand constraints tied to equipment manufacturers' proprietary designs and licensing restrictions.

Recent activity spans Florida and Arizona. Escambia County Correction solicited an extended warranty for X-ray machines (sole-source IFB, August 2026, due August 19), Broward County Aviation Department issued an RFI on June 25, 2026 (due July 28) to test whether maintenance services for Rapiscan 600 and 900 series, VOTI XR3D, and Gemini X-ray systems are available from vendors other than Rapiscan or whether comparable systems exist, Maricopa County posted an IFB for radiologic equipment and installation at three colleges (IFB362910, due October 22, 2026), and Pasco County, Florida solicited large copper sulfate crystals and liquid copper sulfate on an as-needed basis (RFQ, due June 26, 2026). The copper sulfate opportunity appears mistagged to this code and does not align with the X-ray and radiologic equipment focus evident in the other three solicitations. Geographic concentration in Florida and Arizona reflects recent activity, though the code shows limited overall volume in state and local procurement.
