UNSPSC 71131404: Sulfide scavenging services

Scavenge and remove hydrogen sulfide from oil, water and gas phases

UNSPSC 71131404 Sulfide scavenging services, a Commodity code, does not align with the recent state and local procurement activity posted under this classification. The code nominally describes chemical treatment for hydrogen sulfide removal in petroleum and industrial processes; however, the nine recent opportunities tagged to this code span water infrastructure construction, pipeline replacement, bridge replacement, vactor services, and pipe lining—none of which involve sulfide scavenging chemistry or related industrial treatment services. The mismatch suggests either systematic miscoding of water utility and civil construction work or that this code is no longer actively used for its intended purpose by state and local procurement offices.

Recent opportunities show heavy concentration in water main replacement and distribution system expansion across Florida, Georgia, Texas, Connecticut, and Arizona, driven by municipal utilities and county governments. The City of Phoenix issued a five-year requirements contract for vactor services (vacuum truck, jet rodding, hydro-blasting, submersible pumps) due October 19, 2026; Paulding County, Georgia solicited bids for 1,199 linear feet of 16-inch ductile iron pipe water main replacement on Macland Road (bids due September 18, 2026); the Town of Waterford, Connecticut issued two separate IFBs for plastic-to-copper water service replacements (due May 21, 2026 and November 12, 2026); and the City of Alpharetta, Georgia sought on-call pipe lining contractors for storm drainage (CIPP and spincast methods, due May 28, 2026). The City of Atlanta's Department of Watershed Management bid color video pipeline inspection and sewer cleaning equipment (June 23, 2026), while Orange County, Florida requested emergency bridge replacement bids ($6.2 million estimated, due July 7, 2026). This code shows no relevant current activity and should be deprioritized unless your firm has specific expertise in chemical hydrogen sulfide treatment for municipal water systems—a service category not represented in recent solicitations.
