UNSPSC 12352322: Sulphuric acid

A highly corrosive strong mineral acid with the molecular formula H2SO4. It is a pungent, colorless to slightly yellow viscous liquid which is soluble in water at all concentrations. It is widely produced with different methods, such as contact process, wet sulfuric acid process and some other methods. Sulfuric acid is produced from sulfur, oxygen and water via the conventional contact process (DCDA) or the wet sulfuric acid process (WSA). Most sulfuric acid production (60 percent) is consumed for fertilizers, particularly superphosphates, ammonium phosphate and ammonium sulfates.

UNSPSC 12352322 Sulphuric acid is a Commodity code covering chemical inputs for water and wastewater treatment, though recent state and local solicitations show state and local governments procuring a broader range of treatment chemicals under this code than the name alone suggests. The City of Phoenix Water Services Department and the City of Dublin, Georgia have both solicited bids for hydrochloric acid, citric acid, liquid chlorine, hydrofluorosilicic acid, and potassium permanganate — all essential to municipal water treatment and pH adjustment operations. State and local water utilities use these chemicals in multiple container formats (330-gallon totes, 55-gallon drums, one-ton containers, 150-pound cylinders, and smaller portable units) to meet varying operational needs across treatment plants. Procurement under this code targets municipalities with dedicated water and wastewater infrastructure, where chemical specifications demand NSF 60 Standard certification, AWWA approval, third-party lab verification, and strict hazardous-materials compliance documentation including Safety Data Sheets and OSHA labeling protocols.

The City of Phoenix posted IFB 260104 on September 24, 2026, seeking a five-year hydrochloric and citric acid contract with bids due October 16, 2025, and include mandatory DBE and small business participation requirements. The City of Dublin, Georgia posted its water treatment chemicals solicitation on May 22, 2026, with bids due June 8, 2026, offering a twelve-month contract (July 1, 2026 through June 30, 2027) and applying a 3% local-vendor preference. Both solicitations stipulate firm pricing for the contract term and allow the issuing municipality to terminate on notice of price increases. Recent activity centers on Arizona and Georgia; opportunities emphasize rapid delivery capability (five days' notice in Dublin's case) and multi-site delivery coordination across municipal water systems.
