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, a Commodity code, covers chemical disinfectants and treatment agents procured by state and local water, wastewater, and facility-management operations. Recent state and local activity under this code reflects a shift toward on-site disinfectant generation and multipurpose treatment chemistry rather than phosphoric acid alone. Issuing bodies include county governments (Escambia County Board of County Commissioners, Florida) and municipal utilities (City of Flowery Branch, Georgia). The scope of work spans purchase, delivery, and installation of disinfectant-generation equipment; supply of bulk water-treatment chemicals including sodium hypochlorite, sodium hydroxide, aluminum chlorohydrate, citric acid, hydrofluosilicic acid, and polymers; personnel training; and ongoing maintenance and compliance reporting. Drinking water treatment chemicals must meet NSF/ANSI/CAN 60 certification, and generators must be EPA-listed and capable of producing hypochlorous acid at specified concentrations with self-labeling capability.

Activity concentrates in Florida and Georgia. Escambia County posted two related hypochlorous acid generator solicitations—a sole-source procurement (SSC2526004) with a February 25, 2026 deadline and a full competitive RFP (PD2526083) due August 11, 2026—both seeking on-site production equipment with 24/7 maintenance, training, and cybersecurity compliance. The City of Flowery Branch issued an Invitation for Bid (26-007) for a five-year supply contract covering seven chemical products with a mandatory pre-bid meeting on March 24, 2026 and bids due April 21, 2026; the contract includes estimated annual volumes ranging from 9,100 pounds of fluoride to 546,000 pounds of aluminum chlorohydrate, with guaranteed firm pricing required for the initial twelve-month period and optional four-year renewals at the City's discretion. Current suppliers in the Flowery Branch market include Brenntag Mid-South, Inc. and R&M Water Solutions, LLC.
