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 encompasses specialty industrial chemicals used in electrical and gas-insulation applications. Recent state and local solicitations under this code show limited direct alignment with the nominal commodity scope; the two most recent opportunities tagged to this code involve X-ray system maintenance services (Broward County Aviation Department) and copper sulfate supply (Pasco County, Florida), neither of which map to sulfur hexafluoride procurement. State and local issuers appear to use this code infrequently or misalign their tagging, limiting visibility into actual gas-insulation or electrical-equipment-support demand under the nominal category.

Activity is concentrated in Florida, with Broward County Aviation Department issuing a Request for Information (RFI) on June 25, 2026 (responses due July 28, 2026) to determine whether Rapiscan X-ray inspection system maintenance services are available from sources other than the sole-source vendor, and Pasco County posting an RFQ on June 3, 2026 (due June 26, 2026) for as-needed supply of copper sulfate crystals and liquid copper sulfate. Neither opportunity represents a conventional procurement under the sulfur hexafluoride code's stated scope. The code shows no clear pattern of active state or local demand for the specialty gas itself, suggesting either minimal purchasing activity in this category or systematic tagging misalignment that obscures actual buying signals. Firms pursuing sulfur hexafluoride or related gas-insulation contracts should verify code alignment when reviewing recent opportunity postings under this Commodity designation.
