UNSPSC 31121711: Brass centrifugal machined castings

UNSPSC 31121711 Brass centrifugal machined castings is a Commodity code that captures water utility infrastructure components—specifically cast iron and brass pipe repair assemblies and curb box systems—that state and local water departments procure for distribution-system maintenance and field access. The code's name emphasizes material composition, but recent solicitations show that buying activity centers on finished water-utility hardware rather than raw or semi-finished castings. Issuing bodies are limited to municipal water utilities, with the City of Madison, Wisconsin appearing as a repeat buyer within the recent posting window; no state departments, counties, school districts, or transit authorities show activity under this code in the opportunities block. The solicitation profile reflects standard competitive bidding on consumable replacement parts: pipe repair clamps in multiple sizes, curb box assemblies with associated components (dust caps, extensions, lids, rods, and guide rings), and related fittings specified to named manufacturers and material standards.

Activity in the opportunities block is geographically concentrated in Wisconsin, specifically Madison, with both the March 2026 RFQs issued by the City of Madison Finance Department on behalf of the Madison Water Utility. The first solicitation (RFQ 5518, posted March 3, 2026, due March 17, 2026) sought 175 units of stainless steel pipe repair clamps across eleven line items, with acceptable vendors named as Smith-Blair, Mueller, ROMAC, Ford, Cascade, Hymax, A.Y. McDonald, and JCM. The second (RFQ 5517, posted March 3, 2026, due March 17, 2026) called for 150 curb box assemblies and 400 related components (caps, extensions, lids, rods, and repair lids) per Bingham & Taylor specifications. Both RFQs offered a local vendor preference advantage for registered suppliers. No budget values, contract award amounts, or incumbent vendors were disclosed. The code shows limited recent state and local activity—these two Madison solicitations represent the only recent opportunities in the block.
