UNSPSC 31171802: Impeller wheels

UNSPSC 31171802 Impeller wheels is a Commodity code that in recent state and local activity encompasses general metal fabrication services and equipment procurement rather than specialized impeller components. The City of Tucson and Galveston County have posted opportunities that diverge significantly from the code's nominal scope — Tucson solicited broad steel fabrication services including custom doors, railings, and protective structures through an RFP, while Galveston County sought a pneumatic roller for road compaction through a sealed bid ITB. The mismatch between the code designation and actual work being procured suggests that state and local purchasing offices are applying this commodity code to equipment and fabrication work that falls outside a strict interpretation of impeller wheels. Issuers have included a city facilities department and a county road and bridge department, indicating procurement spans municipal infrastructure maintenance and county transportation capital equipment.

Recent activity concentrates in the Southwest, with documented opportunities in Arizona and Texas. The City of Tucson's RFP 240080 for steel fabrication services (due November 30, 2023, with a pre-submittal meeting November 16, 2023) required Section 3 Program compliance and disadvantaged business enterprise participation as HUD-related conditions. Galveston County's ITB 26-085 for a pneumatic roller (posted January 27, 2026, due February 26, 2026) operated under sealed bid procedures with an option clause allowing additional unit purchases at the same price during fiscal year 2026 if initial performance proved satisfactory. The code shows limited recent relevant activity, and the geographic spread and issuing-body mix remain too narrow to establish strong patterns of procurement concentration or buying frequency.
