UNSPSC 31101600: Sand castings and casting assemblies

Objects and assemblies formed to or near their desired shape by introducing molten metal into sand molds.

UNSPSC 31101600 Sand castings and casting assemblies is a Class code; however, the recent state and local procurement activity tagged under it reflects actual purchasing of aggregates and stone materials rather than cast metal products. Columbus Consolidated Government's May 2026 RFB for stone procurement solicits multiple classifications of aggregate materials including #3, #34, and #5 stone, screening materials, crushed stone base, surge stone graded mix, rip-rap, and graded aggregate base—commodities used in road maintenance, construction base layers, and erosion control rather than foundry or casting work. The mismatch between the code's nominal scope and the actual goods being bought suggests either a cataloging error in the source system or that this code has been repurposed locally to classify aggregate procurement. State and local governments using this code designation are sourcing bulk stone and aggregate materials for infrastructure and maintenance applications, typically on annual or multi-year supply contracts with fixed unit pricing.

Columbus Consolidated Government in Georgia is the sole recent buyer appearing in available records, issuing an RFB with a response deadline of June 17, 2026 at 2:30 p.m. Eastern Time. The contract structure awards to two vendors—a Primary and Secondary Contractor selected as the two lowest responsive, responsible bidders—with a two-year initial term and options to renew for three additional twelve-month periods. Estimated monthly usage is approximately 200 tons, with delivery required F.O.B. job site within city limits within two hours of order placement when specified, or pickup available at the vendor's plant. Vendors must provide general liability coverage of $1 million combined single limit, workers' compensation per Georgia statutory requirements, automobile liability of $1 million, and miscellaneous errors and omissions coverage of $1 million. E-Verify registration and Georgia Security and Immigration Compliance Act compliance are mandatory, and all pricing must be inclusive of freight, shipping, handling, and delivery with no additional fees beyond quoted unit prices.
