UNSPSC 51241218: Selenium disulfide

This classification denotes a topical anti-infective agent and selenium compound, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Z69D9E381Q. European Medicines Agency schedules Selenium sulfide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15211MIG. Selenium sulfide generally arises in the molecular formula S2SE. The term 'selenium sulfide' is a European Pharmacopoeia designation. SMILES: S=[SE]=S.

UNSPSC 51241218 Selenium disulfide is a Commodity code that nominally covers chemical products used in industrial and commercial applications, but recent state and local opportunities tagged under this code show limited alignment with the code's stated scope. The most recent solicitation identified—City of Austin IFB 2200 CSH1061, posted July 27, 2026 with bids due August 25, 2026—actually procures liquid aluminum sulfate (alum) for wastewater treatment, a distinct chemical product used to remove soluble phosphorus during the activated sludge process. A second opportunity, City of Tampa Fire Rescue ITB 25-P-00157, covers medical aid supplies (antiseptic sprays, hydrogen peroxide, bandages, first aid kits, and emergency blankets), which falls outside the code's chemical manufacturing scope entirely. These misalignments suggest the code sees little relevant state and local procurement activity aligned to its actual product definition.

The geographic activity visible in the recent records spans Texas (Austin Water) and Florida (Tampa Fire Rescue), though the opportunities themselves do not represent selenium disulfide procurement. The Austin solicitation does illustrate state and local chemical procurement mechanics—firm pricing for 12 months with PPI-indexed adjustments thereafter (capped at 25% per line item), NSF approval and AWWA standards compliance, local and small-business preference discounts (5% for local businesses on bids up to $500,000), and reference requirements from current municipal users. However, without recent opportunities genuinely tagged to selenium disulfide work, the code presents no actionable pipeline for firms focused on that specific product line.
