UNSPSC 31391606: Brass medium precision machining

Brass objects that have been machined to tolerances equal to or greater than 0.020 mm for major dimensions

UNSPSC 31391606 Brass medium precision machining, a Commodity code, covers manufactured brass components and assemblies produced to precision tolerances for state and local government infrastructure and utility systems. Recent state and local solicitations under this code reflect procurement of brass-intensive products such as fire hydrants and related water utility hardware that require machined brass fittings, valve bodies, and threaded connections. State and local governments—predominantly water and utility departments in municipal and county jurisdictions—source these components as capital equipment for infrastructure replacement and expansion projects. The solicitations typically require conformance to detailed technical specifications, industry standards, and performance certifications; itemized pricing by unit and extended total; and adherence to delivery and insurance requirements. Bidders commonly compete on unit pricing, delivery timeline, product brand and specification alignment, and in some jurisdictions, local preference eligibility.

The City of Midland, Texas, acting on behalf of Mason County, posted solicitation 26003721 on March 26, 2026, seeking 71 fire hydrants (45 four-foot units, 20 five-foot units, and 6 six-foot units) for the U25-01 Fire Hydrant Replacement Project, with bids due April 9, 2026, through the Bonfire e-procurement platform. The procurement applied Texas local preference provisions, allowing local bidders within five percent of the lowest non-local price to be considered for award on economic development grounds; no MBE, WBE, SBE, or other set-aside designations were specified. Delivery was F.O.B. to Midland with freight prepaid and included in the bid price, and successful bidders were required to maintain workers' compensation insurance and name the City as additional insured within 21 days of award. The source contains no other recent state and local opportunities under this code, limiting visibility into broader geographic distribution or the frequency of activity across other jurisdictions.
