UNSPSC 40141917: Stone ducts or ductwork

Stone tubing, canal or passage by which fluid or gas is conveyed.

UNSPSC 40141917 Stone ducts or ductwork is a Commodity code that encompasses installation, replacement, and retrofitting of air duct systems and accessories in building mechanical systems, particularly within fire-alarm, smoke-control, and HVAC applications. Recent state and local solicitations show work focused on duct-related components including dampers, terminal boxes, duct heaters, air handling units, energy recovery units, and associated control system integration rather than stone duct material itself. Issuing bodies include county governments, municipal utilities, and school districts. Orange County, Florida and the City of Charlotte represent the most active recent buyers, with additional activity from school districts and utility commissions seeking duct system work as part of broader building automation, chiller maintenance, and facility renovation projects.
