UNSPSC 40141901: Flexible ducts

UNSPSC 40141901 Flexible ducts is a Commodity code covering air duct accessories and components installed as part of building systems, including fire/smoke dampers, terminal boxes, duct heaters, air handling units, and energy recovery units. State and local governments procure these materials primarily through construction and building system modernization projects. Recent solicitations show county facilities departments and municipal utilities as the primary issuing bodies, with work ranging from building automation and fire/smoke control retrofits to water main replacement projects that include associated HVAC components.

Orange County, Florida is actively soliciting flexible duct accessories and related air duct components as part of a $2.89 million Corrections Booking and Release Center building automation system and smoke control upgrade (Solicitation Y26-718, IFB, due October 20, 2026). The scope includes replacement of fire/smoke dampers, terminal boxes, duct heaters, and energy recovery units, with a 5 percent service-disabled veteran preference applied. The City of Leesburg, Florida issued an IFB for 12-inch water main replacement (IFB 26-015-LK, engineer's estimate $975,980.40) that encompasses associated HVAC work including duct components. Geographic activity concentrates in Florida, with additional multi-jurisdictional cooperative purchasing through Sourcewell covering law enforcement equipment (not directly relevant to this code). Recent opportunities show that flexible duct and air duct accessory procurement occurs within larger building systems contracts rather than as standalone commodities, with response deadlines clustered in the third and fourth quarters of 2026.
