UNSPSC 51241205: Calamine

This classification denotes a dermatologic agent with the molecular formula Fe2O4Zn, chemically known as zinc;iron(3+);oxygen(2-), weakly acidic but generally known as calamine, which bears US NIH Compound Identifier 23083748. European Medicines Agency schedules calamine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13155MIG. SMILES: [O-2].[O-2].[O-2].[O-2].[Fe+3].[Fe+3].[Zn+2].

UNSPSC 51241205 Calamine is a Commodity code that in practice captures chemical and pharmaceutical products for municipal operations, though the recent state and local opportunities show significant scope drift and do not align cleanly with the code's nominal name. The City of Austin's IFB 2200 CSH1061 (posted July 27, 2026, due August 25, 2026) solicits liquid aluminum sulfate (alum) for wastewater treatment phosphorus removal—a chemical treatment agent with no connection to calamine. The City of Tampa's ITB 25-P-00157 (posted April 24, 2026, due April 9, 2025) solicits first aid and medical supplies including bandages, antiseptic sprays, hydrogen peroxide, and pain relievers for the Fire Rescue Department. State and local buyers under this code include city procurement offices and municipal utilities; the Austin opportunity specifies local and small business preference discounts (5% and 3% respectively on qualifying bid tiers), while Tampa's solicitation includes set-asides for Small Local Business Enterprises (SLBEs) and Underutilized Woman and Minority Owned Business Enterprises (U-WMBEs) with bid discounts capped at $10,000 and $20,000 respectively. The code shows limited recent activity and apparent tag misalignment—neither opportunity is actually purchasing calamine or products that fit the code's stated scope.

Activity appears concentrated in Texas and Florida, with the Austin opportunity targeting an estimated annual quantity of 179,200 gallons of alum at 47%–49% concentration, delivered FOB destination with firm unit pricing for 12 months and price adjustments not to exceed 25% annually thereafter, and the Tampa opportunity budgeted at $100,000 with quantities ranging from 1 to 2,700 units across 32 line items and a one-year initial award period with two optional one-year renewals. Vendors bidding the Austin alum solicitation must demonstrate manufacturer or authorized dealer status, maintain 9,000-gallon minimum inventory at distribution locations, provide NSF approval and AWWA B403 compliance, and furnish three current Texas municipal references; the Tampa medical supplies procurement requires electronic submission through OpenGov eProcurement Portal and minimum nine-month product expiration dates at acceptance. The code does not reflect meaningful activity aligned with calamine procurement at state or local level and warrants reassessment against actual commodity usage.
