NIGP 43033: Gas Mixtures, Special Purpose

NIGP 43033 Gas Mixtures, Special Purpose is an Item code covering industrial gases and gas cylinder services that state and local governments procure for welding, maintenance, laboratory, medical, and specialized operational uses. Recent state and local solicitations show purchasing bodies acquiring argon-CO2 welding mixtures, oxygen, acetylene, nitrogen, propane, and specialty calibration gases for breath alcohol testing and hazmat detection, alongside related services including cylinder rental, delivery, environmental compliance, and repair. Issuing bodies span community colleges, state corrections departments, state police agencies, and statewide procurement divisions coordinating multi-agency purchases. Collin College (Texas) issued two separate three-year ITBs for welding materials and supplies in early 2024, each with estimated annual volumes around $400,000 and multi-vendor awards; the Mississippi Department of Corrections posted consecutive RFQs for gas cylinder rentals across four operational areas including welding shops, with one-year terms beginning mid-2026.

Recent activity concentrates in Texas and Mississippi, with additional procurement in Oregon and Ohio. The State of Texas Comptroller of Public Accounts issued a statewide RFI in March 2026 for a comprehensive five-year term contract covering laboratory, medical, and welding gases plus dewar rental, serving 25 TxDOT Highway Districts across the state with line items ranging from 1 to 200,000 units depending on product type. The Oregon Department of State Police posted an RFQ in May 2026 for calibration dry gas, repair parts, and consumables for breath alcohol testing with a five-year initial term and extension options. Evaluation criteria across opportunities emphasize purchase price (typically 35 percent), quality, references, vendor historical relationship, and state-vendor status preferences where applicable. Payment terms generally require settlement within 45 days of invoice receipt, and multi-year contracts often include annual price-increase provisions capped at documented cost increases.
