UNSPSC 51241300 Astringents is a Class code under which state and local governments procure chemical treatment products for water and wastewater management, as well as medical and first aid supplies for emergency response and healthcare settings. The work solicited under this code spans unpackaged liquid chemical reagents for municipal wastewater treatment facilities—specifically aluminum sulfate (alum) for phosphorus removal in activated sludge processes—and packaged medical consumables including antiseptic sprays, hydrogen peroxide, pain relievers, and first aid supplies for fire rescue and emergency medical services. Issuing bodies include water and wastewater utilities, fire rescue departments, and city procurement offices; both the City of Austin Water utility and the City of Tampa Fire Rescue Department have solicited under this code in 2025–2026.

Recent opportunities reflect geographic spread across Texas and Florida. The City of Austin posted IFB 2200 CSH1061 on July 27, 2026, requesting bids on liquid aluminum sulfate (alum) for Austin Water's wastewater treatment facility, with questions due August 10, 2026, and bids due August 25, 2026 at 2:00 PM CT; the solicitation specifies 179,200 gallons annually, NSF approval, AWWA B403 compliance, and a 12-month firm price with adjustments capped at 25% thereafter on the anniversary date based on the Producer Price Index. The City of Tampa Fire Rescue Department issued ITB 25-P-00157 on April 24, 2026, for a comprehensive list of medical aid supplies—32 line items including antiseptic sprays, hydrogen peroxide, aspirin, and first aid kits—with an estimated annual budget of $100,000 and set-aside provisions for City-certified Small Local Business Enterprises and Underutilized Woman and Minority Owned Business Enterprises offering up to a 5% bid discount. Both solicitations emphasize local and small business preferences and require certified documentation of vendor responsibility, insurance coverage, and product compliance.
