UNSPSC 12164201: Acid corrosion inhibitors

UNSPSC 12164201 Acid corrosion inhibitors is a Commodity code encompassing chemical products that state and local governments use to control corrosion and hydrogen sulfide in water and wastewater infrastructure. Recent solicitations reveal that municipalities and water authorities are actually procuring a mix of corrosion-control and disinfection chemicals — including hydrogen peroxide, sodium bisulfite, magnesium hydroxide slurry, and sodium hypochlorite — delivered to treatment plants, pump stations, and lift stations to protect against hydrogen sulfide–induced corrosion and odor. Water departments issue these bids on a line-item basis, often requesting firms to bid on individual chemicals where they have capability and supply relationships, and contract terms typically run one to five years with NSF Standard 60 certification and AWWA compliance required across all products. Issuing bodies span municipal water and wastewater utilities, water authorities, and independent school districts; most recent activity centers on line-item or service contract awards where low-cost, reliable delivery within 48 to 72 hours and bulk-tank offloading capability drive competitive advantage.

Geographic activity clusters in Georgia (Cartersville, Griffin, Macon, Gwinnett County, Tallahassee), Texas (Dallas ISD, Lubbock, Temple, Austin), Florida (Orlando, Tallahassee), and Connecticut (Meriden). Representative recent opportunities include the City of Cartersville Water Department's ITB for treatment chemicals at two facilities due October 30, 2026, requiring NSF-60-approved aluminum sulfate, sodium hypochlorite, and sodium bisulfite on annual-delivery schedules; the City of Austin's IFB for sodium bisulfite solution to wastewater treatment plants due June 9, 2026, with a 5% local-business evaluation discount for bids under $500,000; the City of Tallahassee's sealed-bid Magnesium Hydroxide slurry supply contract on a five-year initial term due June 16, 2026, requiring ANSI/NSF Standard 60 certification and delivery within 72 hours; and Dallas ISD's RFP for district-wide water treatment services due October 15, 2026, carrying an SBE compliance requirement with up to 20 percentage points evaluation weight and a 30% aspirational SBE participation goal. Most opportunities carry F.O.B. destination pricing, no fuel surcharges, and fixed unit pricing for the initial contract year with CPI-indexed adjustments thereafter.
