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 (Commodity) encompasses acidic and specialty chemicals that state and local water and wastewater treatment systems procure for routine operational and maintenance needs. Recent opportunities reveal water treatment plants, wastewater facilities, and landfill operations buying sulphuric acid and closely related acids — hydrochloric acid, hydrofluorosilicic acid — alongside complementary treatment chemicals such as copper sulfate, sodium silica fluoride, potassium permanganate, and liquid chlorine. Issuing bodies soliciting under this code include cities (Dublin, Georgia; Orem, Utah), counties (Fayette County, Georgia; Hillsborough County, Florida), and county boards of commissioners managing water reclamation and landfill operations. These are routine, recurring procurements tied to annual water-treatment cycles or multi-year supply agreements rather than one-time capital projects. Vendors competing here must supply NSF 60 Standard certified and AWWA-approved chemicals, maintain rapid delivery windows (typically three to five days), hold appropriate hazardous materials credentials, and demonstrate insurance and compliance documentation.

Activity concentrates in the Southeast, with three recent solicitations from Georgia and Florida between February and June 2026. Fayette County, Georgia issued RFQ 26114-A on March 12, 2026 seeking quotes for 78% sulphuric acid NSF, copper sulfate, and sodium silica fluoride by March 23, 2026. The City of Dublin, Georgia posted water-treatment-chemicals bid PE66427NONST2026 on May 22, 2026 seeking liquid chlorine, hydrofluorosilicic acid, and potassium permanganate for twelve-month supply with sealed bids due June 8, 2026; estimated consumption ran 10–20 tons of liquid chlorine annually and as-needed quantities of hydrofluorosilicic acid in portable totes. Hillsborough County, Florida issued ITB 26-00158 on February 13, 2026 for technical-grade hydrochloric acid (31.5–33.1% by weight) to its Southeast County landfill's leachate-evaporator facility under a three-year contract valued at $412,957.50, with sealed bids due March 4, 2026. The City of Orem, Utah also posted RFP 2026SECONDARY on April 9, 2026 for secondary-digester cleaning and maintenance, a scope outside typical acid supply but sometimes tagged to this commodity code. Pricing firmness over contract duration, local-vendor preferences where applicable, and NSF certification requirements appear consistently across these procurements.
