UNSPSC 47101506: Corrosion control equipment

UNSPSC 47101506 Corrosion control equipment, a Commodity code, encompasses chemical treatment products and delivery services that state and local water utilities deploy to manage hydrogen sulfide, corrosion, and lead-copper control across potable water and wastewater systems. Recent solicitations reveal that buying agencies primarily procure liquid and solid chemical inhibitors—sodium bisulfite, magnesium hydroxide slurry, ortho/polyphosphate blends, and sodium hypochlorite—supplied on firm-fixed or requirements-contract bases with NSF Standard 60 certification mandates and stringent technical specifications. Issuing bodies include city utilities departments, county water and wastewater authorities, and state water agencies. Cities of Austin, Phoenix, Tallahassee, Meriden, Temple, and Griffin have posted ITBs and RFPs for corrosion control and water treatment chemicals within the past ninety days; Volusia County, Florida and Hillsborough County, Florida also issued solicitations for corrosion inhibitor supply and related equipment rental. The code encompasses both chemical procurement and associated delivery infrastructure—tanker trucks, totes, drums, and bulk storage tank systems—reflecting the capital and logistical requirements underlying chemical supply contracts.

Recent activity concentrates in Texas, Florida, Georgia, Connecticut, and California. The City of Austin issued a rebid (IFB 2200BYS1051REBID, due June 9, 2026) for 38% sodium bisulfite solution in 330-gallon totes to two wastewater plants, with local-business evaluation discounts of 3–5 percent applied by contract value tier. The City of Tallahassee (IFB-067-26-CPW, due June 16, 2026) solicited magnesium hydroxide slurry for a five-year initial term with two optional renewals, requiring minimum five years of municipal wastewater supply experience and NSF Standard 60 certification; the City offered Leon County local vendor preference points. The City of Meriden, Connecticut (ITB B026-55, due June 25, 2026) sought water treatment chemicals including calcium hypochlorite and sodium permanganate under Build America Buy America Act compliance, with Connecticut vendor preference applied at tiebreak. Volusia County (ITB #26-B-60LS, due April 13, 2026) procured NSF-certified ortho/polyphosphate corrosion inhibitor for lead and copper control across six treatment facilities. Delivery windows typically range from 48 hours to five business days, and pricing is firm for year one with annual adjustments capped at CPI or producer-price-index changes or mutual agreement. Bidders must carry general liability ($1–$2 million), auto liability ($500,000–$1 million), and workers compensation; subcontractor participation goals vary by jurisdiction. No nationwide set-aside pattern is evident, though local preferences appear consistently in Texas (5 percent) and Florida procurement documents.
