UNSPSC 30121901: Soil stabilizer

A material that improves the physical and or chemical properties of soil. Applied as an organic powder to stabilize in combination of soil particles.

UNSPSC 30121901 Soil stabilizer (Commodity) covers chemical and biological products used to bind, compact, or stabilize soil and unpaved surfaces, including copper sulfate for water treatment and erosion control applications. State and local governments procure these materials primarily for landfill management, stormwater control, and landscape stabilization at county waste facilities and environmental remediation sites. The work involves both supply contracts for chemical stabilizers and service contracts where stabilization is applied as part of broader site management or restoration efforts.

Recent opportunities show activity concentrated in California and Florida. Sacramento County's Department of Waste Management and Recycling issued RFB 2026-RFB-0049 (due June 11, 2026) for erosion control services at multiple landfill and transfer-station sites, requiring hydroseeding of approximately 49 acres across four facilities with annual performance prior to each wet season; the county offers a 5% local business preference and a 2% micro-business preference for state-certified contractors, with a 12-month initial term and four optional one-year extensions. Pasco County, Florida posted RFQFP261004 (due June 26, 2026) seeking on-demand supply of large copper sulfate crystals and liquid copper sulfate under an indefinite-quantity arrangement with one or more vendors. Both procurements reflect county-level environmental and facility-management demand rather than state-department or municipal activity.
