UNSPSC 12142107: Hydrogen sulfide

A colorless, toxic, flammable gas that is responsible for the foul odor of rotten eggs and flatulence.

UNSPSC 12142107 Hydrogen sulfide (Commodity) does not appear in recent state and local procurement activity under this code. The most recent opportunities posted in the dataset involve welding materials and supplies, calibration gases for breath alcohol testing, and industrial gas cylinder rentals — none of which explicitly name hydrogen sulfide as a procured item. Collin College (Texas) and Collin County Community College District posted two ITBs in 2024 for three-year welding materials contracts with estimated annual volumes of approximately $400,000 each, covering welding rods, tungsten electrodes, flat bars, sheets, and tubes in steel, stainless steel, and aluminum compositions, evaluated on purchase price (35%), references (15%), meeting district needs (15%), quality (15%), vendor historical relationship (5%), total cost of ownership (5%), Texas vendor status (5%), and other factors (5%). The Mississippi Department of Corrections issued two RFQs in June 2026 for gas cylinder rentals at Mississippi State Penitentiary, specifying forklift propane, oxygen, acetylene, argon/CO2 mixtures, and nitrogen across warehouse, food service, maintenance, and welding shop operations. The State of Oregon Department of State Police posted an RFQ in May 2026 for calibration dry gas, repair parts, and consumables for CMI Intoxilyzers under a five-year price agreement, and the State of Texas Comptroller of Public Accounts conducted an RFI in March 2026 for a statewide delivery contract covering laboratory, medical, welding, and industrial gases plus dewar rental services across all 25 TxDOT Highway Districts.

The code shows little activity directly aligned to hydrogen sulfide procurement. When issuing bodies do post gas-related opportunities under this taxonomy, the work centers on industrial gases for welding operations, breath alcohol testing supplies, and general-purpose cylinder rentals rather than specialty chemical gases. Geographic activity clusters in Texas (Collin College, Collin County, and the state-level Texas Comptroller RFI), Mississippi (MDOC), and Oregon (state police), with no discernible concentration of hydrogen sulfide-specific demand. Vendors pursuing this code should note the mismatch between the nominal commodity (hydrogen sulfide) and what state and local bodies are actually buying at posting (welding consumables, calibration gases, and standard industrial gas rentals), which suggests either a tagging error in the procurement system or minimal legitimate demand for hydrogen sulfide as a line item under this particular code.
