UNSPSC 12142104: Carbon dioxide gas CO2

UNSPSC 12142104 Carbon dioxide gas CO2 is a Commodity code under which state and local governments procure CO2 in gaseous, liquid, and cylinder forms for water treatment, welding operations, medical applications, and specialized industrial use. Recent solicitations show CO2 being bought as bulk liquid for municipal drinking-water treatment plants, as compressed gas in cylinders for welding programs and maintenance operations, as medical-grade oxygen paired with CO2 for emergency services, and as part of comprehensive industrial gas supply contracts serving multiple municipal departments. The mix of issuing bodies spans city water utilities (Wichita Public Works & Utilities), county environmental agencies (Sarasota County Mosquito Management), transit authorities (Dallas Area Rapid Transit Authority), fire departments (Detroit Fire Department), community colleges (Collin College, Collin County Community College District), and municipal facilities management (City of Orlando Parks). Water utilities and community colleges appear as repeat recent buyers. The geographic spread covers Texas (Austin, Dallas, Collin County, Wichita), Florida (Sarasota, Orlando), Michigan (Detroit), California (Alameda County), Kansas (Wichita), and Missouri (Jackson County), with Texas showing the highest concentration of recent activity. A statewide Texas cooperative procurement (State of Texas Comptroller of Public Accounts RFI 304T-26-430M2) signals broader multi-agency demand across 25 TxDOT districts and all state agencies using general revenue funds.

Representative recent opportunities include the City of Wichita Public Works & Utilities Department RFB 260081 for liquid carbon dioxide delivery to two water treatment facilities (40 and 800 tons annually, sealed bids due May 1, 2026, with NSF certification and emergency 12-hour delivery required); the Dallas Area Rapid Transit Authority BPO REQ2098359 for welding and inert gases including CO2 cylinders, argon, nitrogen, and acetylene for bus and rail maintenance with mandatory site-visit attendance and two-business-day exchange service (bids due June 2, 2026); Sarasota County IFQ 262793WG for CO2 and oxygen cylinder rental and refill services for mosquito management with quarterly contract values capped at $150,000 (proposals due January 21, 2026); and the Alameda County Water District IFB 25/26-29 for liquid oxygen and carbon dioxide supply to a single treatment plant with five-year minimum vendor experience and NSF 60 certification required (bids due May 1, 2026). Evaluation emphasis across these opportunities centers on unit pricing, delivery speed and reliability (24-hour emergency windows common), documented experience in the specific application, proof of regulatory compliance (NSF, DOT, OSHA), and insurance adequacy. No set-aside programs appear consistently across these solicitations; municipal local-vendor preferences and minority-business enterprise participation are noted selectively in individual jurisdictions.
