UNSPSC 11111600: Stone

UNSPSC 11111600 Stone (Class) covers aggregate materials and dimensional stone that state and local governments procure for infrastructure maintenance, construction, and landscaping projects. Recent solicitations show state and local buyers purchasing crushed stone, gravel, granite rubble, cobble rock, and graded base materials for road construction, water and sewer infrastructure support, and facility maintenance. The code draws bids from counties, municipalities, state agencies, and special-purpose districts including water authorities and parks departments. A two-vendor award structure appears in some contracts, with Primary and Secondary Contractors selected as the two lowest responsive bidders; pricing is typically fixed for initial contract periods with limited escalation provisions thereafter. Buyers often specify delivery options (FOB job site, pickup, or delivered), material gradations, and volume ranges, with contracts running one to three years and renewable for additional periods. Insurance and compliance requirements vary by jurisdiction but commonly include general liability minimums of $1 million and E-Verify registration.
