UNSPSC 30111801: Natural aggregate

A natural aggregate without the need of crushing requiring only washing and selection of gradation.

UNSPSC 30111801 Natural aggregate (Commodity) covers sand, gravel, stone, and crushed materials that state and local governments procure for road maintenance, landfill operations, water infrastructure, and department-level supply needs. The code sees activity across counties, cities, and special-purpose districts—primarily public works departments, sanitation districts, and transit or water authorities—with recurring buyers including Ada County, Jackson County, Bergen County, and the City of Detroit. Recent solicitations span supply contracts (sand for county departmental use, drain gravel for landfill operations), unit-pricing agreements for aggregate road materials and fill products, and quotations for specific tonnage deliveries to municipal stockpiles.

Geographic activity centers on the Mountain West (Idaho, Colorado), upper Midwest (Missouri), and Texas, with additional recent solicitations from California (Santa Clara County), New Jersey (Bergen County), and Michigan (Detroit). Representative opportunities include Jackson County, Missouri seeking a twenty-four-month aggregate sand supply contract with a twelve-month extension option (RFQ 26067, due November 3, 2026); Ada County soliciting 4,261 tons of drain gravel for landfill use (ITB BID27004, due September 12, 2026); and the City of Detroit requesting aggregate materials including 5,000 tons of MDOT 23A stone, 1,000 tons of sand, and 5,000 tons of slag for street maintenance under a two-year blanket purchase agreement restricted to Detroit-based certified businesses (RFQ 546989, due June 5, 2026).
