UNSPSC 31101617: Grey iron sand casting

Grey iron object cast from sand molds

UNSPSC 31101617 Grey iron sand casting is a Commodity code covering the production of grey iron castings using sand-mold foundry processes — a core input for state and local government procurement of heavy equipment, infrastructure components, and replacement parts for water systems, wastewater treatment facilities, transit authorities, and public works departments. State and local buyers source grey iron castings for pump housings, valve bodies, pipe fittings, structural brackets, and industrial equipment frames where ductility, machinability, and cost-effectiveness outweigh the properties of ductile iron or steel alternatives. Issuing bodies soliciting under this code span state departments of transportation and environmental quality, county public works and utilities departments, municipalities with legacy water infrastructure, and special-purpose water and sewer districts managing aging systems.

The recent state and local contract opportunities block contains no entries for this code, indicating minimal recent solicitation activity at the state or local level under UNSPSC 31101617. Without posted RFPs, RFQs, or ITBs naming this commodity code in the past twelve months, characterization of geographic concentration, issuing-body repeat patterns, or representative recent work is not supported by the source. Firms pursuing state and local grey iron casting contracts should monitor cooperative purchasing vehicles, master supply agreements with regional water authorities, and equipment replacement cycles at legacy facilities in the upper Midwest and Northeast where older cast-iron water and sewer infrastructure remains prevalent, but current market signals from formal state and local procurement channels are absent.
