UNSPSC 30111800: Aggregates

Inert granular materials that are combined and solidified with cement and water to make mortar or concrete. Composed of sand, gravel, crushed stone and others.

UNSPSC 30111800 Aggregates is a Class code covering the supply and delivery of sand, gravel, crushed stone, recycled materials, and related bulk mineral commodities for road construction, maintenance, park and facility operations, and infrastructure projects. State and local governments procure aggregates through a mix of county departments, city public works and parks divisions, state transportation departments, water districts, sanitation districts, and special-purpose authorities. Recent activity shows counties and municipalities issuing primarily IFBs and RFQs for aggregate supply contracts, typically structured as unit-price agreements with firm fixed pricing, multiple line items by material type and delivery location, and terms ranging from six months to three years with optional renewals.

Missouri Department of Transportation dominates the recent activity, with multiple districts (Southwest, Kansas City, Central, Northwest) posting IFBs for aggregate materials—haydite, manufactured sand, and various stone and gravel sizes—to serve highway maintenance and construction across dozens of county locations, all due between May and August 2026. Outside Missouri, activity clusters in the West (Orange County California, Salt Lake County Utah, Ada County Idaho, North Texas Municipal Water District, Boulder County Colorado) and Northeast (Bergen County New Jersey, Salem Massachusetts, Middlebury Connecticut, Lexington Massachusetts), with Jackson County Missouri, Santa Clara County California, and Detroit Michigan also active. Representative recent solicitations include Orange County Community Resources (IFB for sand, gravel, aggregate base, and decomposed granite to 31 parks, due November 2, 2026, with 5–8 percent preference for Orange County local small businesses and disabled veteran enterprises), Jackson County Missouri (24-month supply contract for aggregate sand across county departments, due November 3, 2026), Salt Lake County Public Works Flood Control (riprap, rockfill, and galvanized gabion baskets for Rose Creek stabilization, due September 10, 2026), and MoDOT Kansas City District (14 line items totaling 10,050 tons of surfacing aggregate, base course, and snow control chips, due July 31, 2026, with 10 percent American-made preference and MBE/WBE encouragement). Most solicitations require firm pricing per ton, FOB destination with freight prepaid, compliance with state standard specifications and ASTM/AASHTO standards, minimum delivery quantities (typically 500 tons per day), performance and payment bonds, and commercial general liability insurance in the $1–2 million range.
