NIGP 43033: Gas Mixtures, Special Purpose

NIGP 43033 Gas Mixtures, Special Purpose, an Item code, covers gases and gas mixtures that state and local governments procure for specialized industrial, occupational health, and testing applications—notably calibration gases for breath alcohol testing, welding-shop argon/CO2 and acetylene mixtures, propane for forklifts, and oxygen and nitrogen for maintenance and fabrication work. Recent solicitations show state and local buyers purchasing these gases primarily through rental or supply agreements rather than outright commodity buys, often bundled with delivery, environmental compliance, and surcharge fees. Issuing bodies include state departments (corrections, transportation, state police), community colleges, and other facilities with ongoing operational gas needs. The buying pattern reflects routine consumption across multiple operational locations rather than one-time bulk procurement—gas cylinders rotate through maintenance shops, welding facilities, food service operations, and vehicle-support areas.

State Penitentiary facilities in Mississippi dominate recent activity, with the Mississippi Department of Corrections issuing multiple RFQs (three separate solicitations between June and August 2026) for gas cylinder rentals across the Mississippi State Penitentiary in Parchman, covering forklift propane, oxygen, acetylene, argon/CO2 mixtures, and nitrogen across four facility areas with one-year terms and single-award structure. The Washington State Department of Transportation's Washington State Ferries issued RFP20260825 (due October 9, 2026) for occupational medical surveillance services that includes provision for specialized gases used in workplace health monitoring. The State of Oregon Department of State Police posted RFQ S2570000016654 (due May 15, 2026) for calibration dry gas and breath alcohol testing supplies under a five-year price agreement. Educational procurement appears in Collin College's two-bid welding-materials solicitations (both posted July 2026, with response dates in March and April 2024) covering welding rod, tungsten electrodes, and associated gases over three-year terms with estimated annual volumes around $400,000 per contract. The recent activity concentrates in the South and Pacific Northwest, with isolated educational procurement in Texas.
