UNSPSC 12141901: Chlorine Cl

UNSPSC 12141901 Chlorine Cl is a Commodity code covering chlorine products procured by state and local water and wastewater treatment authorities, municipalities, school districts, and special-purpose water districts for disinfection, pH adjustment, and oxidation in potable water, reclaimed water, and wastewater treatment systems. State and local buyers source chlorine in multiple physical forms—primarily gas in 1-ton containers and 150-pound cylinders for municipal water treatment plants, and as sodium hypochlorite solution (12.5% available chlorine) and calcium hypochlorite granular for pool and fountain facilities. Recent solicitations show sustained demand across the issuing-body mix: municipal water departments (Phoenix, Wichita, Dublin Georgia, Griffin Georgia, Tampa, Salt Lake County), school districts (Pinellas County Florida, Washtenaw Intermediate School District Michigan), counties (Okaloosa County Florida, Hillsborough County Florida), and a state-level procurement (California). Specification requirements are consistent across buyers—all chlorine products must carry NSF Standard 60 and AWWA certification; gas chlorine must meet purity and container standards with Department of Transportation certification; and sodium hypochlorite and calcium hypochlorite must meet precise concentration and chemical composition tolerances. Delivery logistics are operationally critical: municipal water treatment plants require three- to five-day turnaround on bulk tanker loads, with 24-hour emergency service mandated; pool facilities require weekly or bi-weekly scheduled delivery during peak season with emergency response within six hours.

Geographic activity concentrates in the Southeast (Florida, Georgia, South Carolina) and Mountain West (Utah, Colorado, Arizona, Kansas), with Midwest school-district activity (Michigan). Representative recent solicitations include the City of Phoenix Water Services IFB 26-0153 for a five-year chlorine supply contract (1-ton and 150-pound containers, bids due December 23, 2025); the City of Tampa Parks & Recreation ITB 25-P-00118 for sodium hypochlorite and sulfuric acid with an estimated contract value of $250,000 (bids due March 6, 2025); the City of Dublin Georgia IFB for liquid chlorine, hydrofluorosilicic acid, and potassium permanganate (bids due June 8, 2026); and the Washtenaw Intermediate School District RFQ for pool chemicals including sodium hypochlorite and calcium hypochlorite via the CoPro+ cooperative purchasing program (proposals due May 8, 2026). Contract terms typically span one to five years with firm fixed pricing for the initial term and documented cost-adjustment provisions thereafter. Municipal water authorities consistently reserve the right to award multiple suppliers per chemical category to ensure capacity and competitive redundancy, and many require vendors to maintain NSF 60 certification, comprehensive general liability insurance ($1 to $2 million per occurrence), and active state business registration throughout the contract term.
