UNSPSC 31121011: Brass v process machined castings

UNSPSC 31121011 Brass v process machined castings is a Commodity code covering water utility infrastructure components — specifically pipe repair clamps, curb boxes, and related cast iron or brass assemblies — that state and local water departments procure for potable water system maintenance and replacement. The recent solicitations show municipal water utilities buying finished brass and cast iron components designed for integration into existing water distribution networks rather than raw materials or unfinished castings. These are typically engineer-specified items purchased in moderate quantities (150 to 175 units per solicitation) from established manufacturers with specific model numbers and material standards. Issuing bodies have been municipal water utilities operating under city finance and purchasing departments; the City of Madison Water Utility has posted multiple RFQs under this code in the same narrow timeframe, suggesting repeat buying activity for ongoing system maintenance.

The code shows concentrated recent activity in the Upper Midwest, specifically Wisconsin, where the City of Madison Finance Department's Purchasing Services issued two RFQs in early March 2026 — one for stainless steel pipe repair clamps (551802026BG, due March 17, 2026) and one for cast iron curb box assemblies with brass hardware (551802026BG, due March 17, 2026). Both procurements were structured as competitive quotations with evaluation weighted toward cost, quality, delivery, and past performance, with a local vendor preference available to registered suppliers. Acceptable manufacturers for these components are pre-specified (Smith-Blair, Mueller, ROMAC, and Ford for clamps; Bingham & Taylor for curb boxes), pricing must be firm for one year, and all material must deliver FOB to the utility's designated receiving location with 24-hour advance notice. Beyond Madison, the source documents no additional recent state or local activity under this code.
