UNSPSC 51241810 Aluminum potassium sulfate/chlorobutanol/tannic acid is a Commodity code that in recent state and local procurement covers chemical treatment products for municipal water and wastewater systems. The Austin Water Department's recent IFB for liquid aluminum sulfate (alum) demonstrates the actual scope: unpackaged liquid chemical coagulants used to remove phosphorus and other contaminants during wastewater treatment. State and local water utilities and municipal departments are the primary buyers under this code, procuring bulk chemical supplies to support activated sludge and other treatment processes.

Recent activity shows Austin Water as a buyer under this code, with the City of Austin posting IFB 2200 CSH1061 on July 27, 2026, for 179,200 gallons annually of liquid aluminum sulfate at 47–49% concentration, with bids due August 25, 2026. The solicitation applies local business and small business preference discounts of 3–5% depending on bid size and qualifies bidders based on NSF approval, AWWA B403 compliance, inventory capacity (minimum 9,000 gallons at distribution locations within 500 miles), and references from current Texas municipal wastewater facilities. Pricing is firm for 12 months with potential adjustments capped at 25% annually based on the Producer Price Index. Texas is the geographic focus for the recent opportunity identified; no other states appear in the source material.
