UNSPSC 30131506: Natural rock slab

UNSPSC 30131506 Natural rock slab is a Commodity code covering stone materials and aggregates that state and local governments procure for trail construction, grounds maintenance, erosion control, and infrastructure projects. Recent solicitations show counties and municipalities buying granite rubble stone, rip-rap, flagstone, sandstone, crusher fine, road base, and stackable stone for both immediate supply needs and longer-term materials contracts. Issuing bodies include county departments of infrastructure and parks, city public works divisions, and special-purpose entities such as park and open space departments. DeKalb County, Georgia; Columbus Consolidated Government, Georgia; Boulder County Parks and Open Space Department, Colorado; and Farmington City, Utah have all posted active procurement under this code within the past four months.

DeKalb County issued ITB 2026-030-ITB on May 18, 2026 for a three-year multiyear contract to supply and deliver granite rubble stone in one-man and two-man sizes to various county locations, with sealed bids due June 17, 2026 at 3 p.m. via OpenGov.
