UNSPSC 30111801: Natural aggregate

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

UNSPSC 30111801 Natural aggregate is a Commodity code that covers supply and delivery of crushed stone, sand, gravel, and recycled aggregate materials used in road construction, pavement rehabilitation, and site preparation work by state departments of transportation, county public works departments, municipalities, and special-purpose districts. Recent solicitations show state and local buyers procuring raw aggregates (granular borrow, crusher fine, rip-rap, recycled asphalt) for road base and fill, finished aggregate products (stone, sand, slag) for asphalt overlay and paving work, and erosion control and landscaping aggregates (topsoil, mulch, river rock, stackable stone) through a mix of IFBs, RFQs, and cooperative purchasing arrangements. The issuing bodies span departments of transportation (UDOT, ODOT), city and county public works offices (Detroit, Santa Clara County, Barrow County), special districts (Boulder County Parks and Open Space), regional solid waste authorities (Maryland Environmental Service), and cooperative purchasing groups covering multiple municipalities.

Activity concentrates in the West (Utah, Oregon, California), Midwest (Michigan), and scattered East Coast jurisdictions (Georgia, Maryland, Massachusetts), with recent high-volume procurements underway across these regions through mid-2026. Representative opportunities include the Utah Department of Transportation's granular borrow delivery and stockpile IFBs (UDOT260230CN and UDOT260221CN, due April 21–22, 2026) for 3,000 to 5,000 cubic yards each; the City of Detroit Office of Contracting and Procurement RFQ 548310 (due June 29, 2026) for 3,000 tons of bituminous aggregate wearing course 36A with Detroit-based business equalization preferences of 1–5 percent; the Berkshire Regional Group Purchasing Program's cooperative FY27 aggregates and loam bid (due April 2, 2026, now closed) covering 32 participating Massachusetts municipalities; and the Oregon Department of Transportation's request for competitive quotes for 10,000 cubic yards of sanding rock at Brooks Quarry (due April 23, 2026). Many solicitations require bidders to demonstrate two years of prior experience, maintain liability insurance of $1–3 million, and meet ASTM and AASHTO material standards with delivery F.O.B. destination freight prepaid.
