UNSPSC 12352147: Phosphoric acid

Phosphoric acid, also known as orthophosphoric acid, is a triprotic acid that exists as a dense liquid. It is an irritant or corrosive to the skin, eyes, and other mucous membranes of both humans and laboratory animals. Its salts, though, exhibit a significantly lower irritancy potential.

UNSPSC 12352147 Phosphoric acid is a Commodity code that reflects state and local procurement of chemical products and related services for facility operations, disinfection, and waste management—a broader scope than the code name alone suggests. Recent opportunities show municipalities and special districts procuring herbicides for parks maintenance, on-demand disinfectant generators with associated installation and maintenance support, and sludge and liquid waste hauling services. The issuing bodies are primarily cities and special-purpose districts (wastewater authorities, county boards) rather than state departments or school systems; Philadelphia and Escambia County appear as active buyers, alongside regional authorities managing environmental compliance and facility operations.

Activity is scattered across the South and mid-Atlantic regions. Philadelphia posted an herbicide quotation (RFQ, City of Philadelphia Procurement Department, due October 14, 2026) for up to $45,000 annually across six city districts. Escambia County (Florida) solicited proposals for a hypochlorous acid generator system with delivery, installation, training, and ongoing maintenance (Solicitation PD2526083, due August 11, 2026). The Brazos River Authority (Texas) requested sealed bids for sludge hauling and liquid waste disposal across four wastewater treatment plants (IFB 261394, due August 20, 2026 at 10:00 a.m.), with annual sludge volumes totaling approximately 15,040 tons and pricing quoted per ton. These opportunities reflect the code's actual use for facility maintenance chemicals, water treatment, and environmental compliance services rather than bulk phosphoric acid procurement.
