UNSPSC 12142108: Carbon monoxide

Carbon monoxide with the chemical formula CO, is a colorless, odorless, and tasteless gas.

UNSPSC 12142108 Carbon monoxide, a Commodity code, sees minimal direct procurement activity in recent state and local solicitations; the opportunities tagged under this code predominantly involve oxygen, nitrogen, argon, helium, and other industrial gases, medical gases, and specialty chemicals rather than carbon monoxide itself. State and local governments do purchase industrial and medical gases through this family when they appear on procurement records, but carbon monoxide as a standalone commodity does not feature in the representative recent opportunities. The issuing bodies span state environmental agencies (Illinois EPA), state transportation departments (Washington State Department of Transportation), municipalities (City of Sanford, City of Phoenix, City of Lubbock, City of Arlington, City of Orlando), counties (Santa Clara County), state universities (University of Georgia), and special-purpose districts (Harris County Institute of Forensic Science, Collin College). Illinois state agencies—particularly the Department of Central Management Services and the Environmental Protection Agency—appear as repeat buyers for industrial and medical gas supplies through joint purchase master contracts and individual competitive solicitations.

Recent opportunities under and near this code show activity across Florida, California, Illinois, Washington, Texas, and Georgia. Representative recent work includes the City of Sanford, Florida's Invitation for Bid (IFB 252611) for bulk liquid oxygen delivery and maintenance at its Water Treatment Plant, with sealed bids due April 9, 2026; Santa Clara County's Invitation to Bid (ITB-PRC-FY26-0636) for medical gas inspection, certification, and preventative maintenance requiring ASSE 6000 certification, with bids due October 7, 2026; the Illinois Environmental Protection Agency's Invitation for Bid for ultra-high-purity helium, nitrogen, and argon gases with bids due September 10, 2026; and the State of Illinois' noncompetitive change order extensions for oxygen cylinder tanks and rentals and laboratory gas cylinder rentals through December 31, 2026. The code shows steady activity in municipal water and wastewater treatment, state laboratory operations, and medical surveillance programs, but carbon monoxide procurement itself remains absent from recent posted opportunities.
