UNSPSC 40141925: Air and flue gas ducting

Ducts are defined as air tight conduits that convey air or flue-gas under positive or negative pressure.

UNSPSC 40141925 Air and flue gas ducting is a Commodity code that captures ductwork and ducting systems for air handling and flue gas management in building HVAC and industrial exhaust applications. State and local procurement activity under this code shows minimal recent documented solicitations; the three opportunities posted between May and July 2026 do not reflect active procurement volume for air and flue gas ducting itself. Of the three records, one is an administrative relocation notice for Williamson County Purchasing Department in Texas (not a procurement opportunity), one is a Texas contract reference lacking scope detail (IW254390), and one is a Sourcewell cooperative RFP for law enforcement equipment (061626) that is unrelated to ducting and appears to be miscoded. State and local governments do procure ducting systems when building new facilities, renovating HVAC infrastructure, or upgrading industrial exhaust systems, but the recent opportunity data does not show active demand under this specific code at this time.

The geographic spread of recent activity is limited; the two records with a state identifier point only to Texas and the Sourcewell cooperative framework (which operates nationwide but was posted by Minnesota-based Sourcewell on behalf of Washington-state participating entities). The source provides no representative active opportunities for air and flue gas ducting procurement with a clear scope, issuing body, notice type, and response date. Firms tracking this code should monitor for RFPs and IFBs from facilities-focused state agencies, county maintenance departments, school districts planning capital construction, and municipal utilities managing flue gas systems; current vacancy in recent postings suggests either seasonal lull or a shift to direct-award or cooperative-purchasing vehicles that do not generate posted notices.
