UNSPSC 23131514: Mounted stones

UNSPSC 23131514 Mounted stones, a Commodity code, encompasses stone materials that state and local governments procure for public works, infrastructure, and facility maintenance. Based on recent solicitations, the code captures purchases of aggregates and stone classifications — including #3, #34, and #5 stone, screening materials, crushed stone base, surge stone graded mix, rip-rap types, and graded aggregate base — typically sourced on an as-needed or annual-contract basis. Issuing bodies under this code include county governments and city consolidated governments, with municipalities and county public works departments serving as primary end-users. The solicitations reveal demand for F.O.B. delivery or job-site pickup arrangements, with vendors required to carry general liability, workers' compensation, and automobile liability insurance; E-Verify registration; and compliance with state immigration and security acts.

Columbus Consolidated Government in Georgia posted an RFB on May 14, 2026 for stone under an annual contract (RFB No. 26-0037), with bids due June 17, 2026, seeking two award recipients — Primary and Secondary Contractors — to supply approximately 200 tons monthly across fourteen stone classifications at fixed pricing for an initial two-year term with three optional one-year renewals. The recent-opportunities block shows limited additional solicitation activity under the code; a Cobb County, Georgia pest control services RFP posted June 12, 2026, and a Williamson County, Texas purchasing department relocation notice posted July 14, 2026, are unrelated to mounted stone procurement. Geographic activity is concentrated in Georgia, with Columbus and Cobb County representing the identifiable recent market. Vendors pursuing this code should expect commodity-style annual or multi-year contracts, tight delivery windows, and relatively standard insurance and compliance requirements common to municipal public works supply agreements.
