UNSPSC 12142105: Industrial air

UNSPSC 12142105 Industrial air is a Commodity-level code covering specialty gases—including welding gases (acetylene, argon, argon-CO2 mixes), inert gases (nitrogen, helium), medical-grade oxygen, and gases used in water treatment (liquid carbon dioxide, liquid oxygen)—that state and local governments procure for maintenance, safety, operational, and utility functions. Recent solicitations show procurement bodies buying both bulk industrial gases delivered via cylinder exchange or tanker truck and rental-based gas supply arrangements with emergency response requirements. Issuing bodies span city public works and utilities departments, county transit authorities and county water districts, school districts and colleges, and state procuring offices. Texas entities—including Collin College, Collin County Community College District, the City of Dallas, the State Comptroller's Statewide Procurement Division, and the City of Austin—dominate recent activity, though Michigan, Florida, California, Missouri, and Kansas jurisdictions have also posted solicitations under this code. Collin College and Collin County Community College District each issued a three-year welding materials and supplies contract (ITB FY2024ITB020 and ITB FY2024ITB024, both with March–April 2024 response dates) estimated at approximately $400,000 annually per institution; Dallas Area Rapid Transit Authority posted a blanket purchase order for welding and inert gases with a mandatory site visit requirement and June 2, 2026 response date; and the City of Wichita, Kansas issued an RFB for liquid carbon dioxide delivery to two water treatment facilities with a May 1, 2026 due date.

Geographic concentration is strongest in Texas, with recent activity also in Florida (Sarasota County IFQ for CO2 and O2 cylinder rental and refill for mosquito management; City of Orlando IFB for liquid CO2 system servicing), California (Alameda County Water District IFB for liquid oxygen and CO2 delivery), Michigan (City of Detroit RFQ for medical-grade oxygen in H-size tanks), and Kansas (City of Wichita RFB for liquid CO2). The State of Texas Comptroller's Statewide Procurement Division issued a Request for Information for a five-year mandatory-use industrial gases and dewar rental contract spanning all state agencies and 25 TxDOT highway districts, with 129–137 line items and estimated quantities ranging from single units to 200,000 units per line item, reflecting the broadest scope of recent state-level activity. Evaluation criteria across solicitations emphasize total cost of ownership, quality, delivery speed (including emergency response within 12–24 hours), vendor experience (typically three to five years in the service area), and compliance with safety standards (DOT, OSHA, CGA, NSF, UL, ASME). Insurance requirements are standard across municipal and county solicitations, ranging from $1 million to $5 million in combined general liability coverage, and many entities apply local business preferences or consider MBE, WBE, and VBE participation in award decisions.
