UNSPSC 30131604: Stone bricks

UNSPSC 30131604 Stone bricks is a Commodity code that encompasses the supply and delivery of aggregates, stone materials, and related landscaping products to state and local governments for infrastructure maintenance, grounds improvement, and emergency response operations. Recent solicitations show state and local buyers purchasing stone bricks primarily through supply contracts for aggregates and erosion control materials, annual stone supply agreements for road base and construction fill, and specialized installations of synthetic stacked stone on public facilities. The issuing bodies span county governments, municipal departments, state agencies, and regional authorities — notably Columbus Consolidated Government (Georgia), Boulder County Parks and Open Space Department (Colorado), Hillsborough County Board of County Commissioners (Florida), the State of Georgia Department of Driver Services, and Atlanta BeltLine, Inc. (Georgia). Work ranges from routine as-needed material delivery for public works operations to specialized decorative stone installation at government customer service centers and public venues.

Activity under this code appears across multiple states, with recent concentration in Georgia (Columbus, Atlanta BeltLine, and Department of Driver Services solicitations), Colorado (Boulder County), and Florida (Hillsborough County). Columbus Consolidated Government issued an RFQ for stone (fourteen classifications including #3, #34, #5 stone, rip-rap, and graded aggregate base) on May 14, 2026, with bids due June 17, 2026, awarding to two vendors on an annual contract basis with estimated monthly usage of approximately 200 tons.
