UNSPSC 12142114: Liquid oxygen

Liquid oxygen is a cryogenic fluid, oxygen in a liquid state at an extremely low temperature.

UNSPSC 12142114 Liquid oxygen, a Commodity code, covers the supply and rental of bulk liquid oxygen used primarily in municipal water treatment, fish hatchery operations, and specialized laboratory and industrial applications. State and local jurisdictions procure liquid oxygen on a recurring basis for dissolved oxygen adjustment in aquatic systems and for water quality management. The code encompasses delivery of cryogenic liquid oxygen in tanker truck or cylinder form, tank rental and maintenance services, and equipment servicing on an as-needed or scheduled basis.

Recent solicitations show activity concentrated in state environmental protection agencies, municipal water utilities, county fish and wildlife departments, and local government purchasing offices. The Illinois Environmental Protection Agency, Idaho Department of Fish and Game, City of Peoria Water Services, City of Sanford Water Treatment, and City of Wichita Public Works have all posted opportunities under or closely aligned with this code within the past ninety days. Procurement approaches vary: some jurisdictions issue formal IFBs with five-year initial terms and renewal options; others seek shorter one-year contracts with annual renewal periods. The City of Peoria issued IFB P26-0036 for liquid oxygen supply to its Greenway Water Treatment Plant (response due April 17, 2026), specifying delivery of approximately 50,000 gallons annually in 5,000-gallon loads at six-day intervals. The Idaho Department of Fish and Game solicited proposals for bulk oxygen and tank rental to support the Nampa Fish Hatchery's operation of approximately 500,000 Rainbow Trout (response due July 28, 2026). Geographic activity is scattered across the Southwest, Midwest, and Southeast—Arizona, Illinois, Idaho, Florida, Kansas, and Texas all show recent postings. Standard procurement terms require F.O.B. destination pricing, emergency delivery capability (often within 8 to 24 hours), hazardous-materials compliance, commercial liability insurance minimums of $1 million, and firm pricing for the initial contract term with CPI-indexed adjustments thereafter. No set-asides or disadvantaged-enterprise preferences appear in the available solicitations.
