UNSPSC 31121116: Bronze die machined castings

UNSPSC 31121116 Bronze die machined castings, a Commodity code, encompasses metal castings and casting components that state and local water utilities and municipal departments procure for infrastructure repair and maintenance. Recent state and local solicitations under this code reflect demand for cast iron and related ferrous metal components used in water system operations, particularly pipe repair apparatus and valve box assemblies. Issuing bodies soliciting under the code include municipal water utilities and city purchasing departments acting on their behalf; the City of Madison, Wisconsin has posted multiple quotations for such components within the past four months. Work involves supplying pre-manufactured castings meeting specified material standards—such as tar-coated cast iron construction—along with associated hardware and subassemblies ready for field installation without further machining or modification.

The City of Madison Water Utility has driven recent activity in this code space, issuing two RFQs in early March 2026 for stainless steel pipe repair clamps (due March 17, 2026) and cast iron curb box assemblies with dust caps, extensions, lids, and rods (also due March 17, 2026). Both solicitations required FOB delivery to Madison and emphasized local vendor preference scoring; the clamp RFQ specified acceptable manufacturers including Smith-Blair, Mueller, ROMAC, Ford, Cascade, Hymax, A.Y. McDonald, and JCM, while the curb box RFQ named Bingham & Taylor model 94F as the specified manufacturer. Wisconsin shows the most recent documented activity under the code, though the volume of recent opportunities remains limited.
