UNSPSC 12352308 Silicates is a Commodity code covering mineral aggregates and related materials that state and local governments procure for construction and maintenance work. Recent solicitations under this code show government buyers acquiring rock, base material, sand, rip rap, and other aggregate products for road construction, site preparation, and facility maintenance. Sarasota County, Florida, and similar municipal and county public works departments represent the primary issuing bodies soliciting under this code, with procurement typically structured as invitation for bids (IFB) with multiple award slots to ensure supply redundancy and competitive pricing. Scope of work emphasizes conformance to state transportation standards specifications, delivery logistics (including contractor pickup options and geographic sourcing constraints), and insurance requirements for vehicles and liability coverage.

Sarasota County, Florida, posted the most recent representative opportunity on this code—Invitation for Bids #262819AMS on February 26, 2026—seeking rock, aggregates, and other materials for delivery to county locations across three procurement groups with differing delivery and sourcing models. The solicitation required bidders to meet qualification thresholds including two references for contractor-delivery groups demonstrating prior aggregate supply experience within seven years, establish $1,000,000 combined single-limit business automobile liability insurance, and maintain 48-hour response times for standard requests and 24-hour response for emergencies. Group 3 materials faced a geographic constraint limiting sourcing to locations within 60 driving miles of the county boundary, and the county intended to award up to three contracts per group or line item with an initial one-year term. No set-aside designations or local vendor preferences applied due to grant funding requirements, and responses were due through the OpenGov Procurement portal.
