UNSPSC 12162601: Inorganic clay stabilizers

UNSPSC 12162601 Inorganic clay stabilizers, a Commodity code, captures soil and water treatment chemicals that state and local governments procure to manage erosion, prevent sediment mobilization, and stabilize unpaved surfaces. Recent solicitations show the code drawing purchases of copper sulfate formulations (crystals and liquid) and erosion-control seed mixes and stabilizing agents applied via hydroseeding to landfill slopes and other vulnerable earth surfaces. The work spans county waste management and environmental operations, with issuing bodies including county departments of waste management and environmental services purchasing on an as-needed or annual service basis.

Recent activity concentrates in Florida and California. Pasco County, Florida released RFQFP261004 on June 3, 2026, seeking vendors to supply large copper sulfate crystals and liquid copper sulfate on an indefinite-quantity, as-needed basis with proposals due June 26, 2026. Sacramento County's Department of Waste Management and Recycling issued RFB 2026-RFB-0049 on May 14, 2026, for erosion control services at multiple County landfills and transfer stations, requiring hydroseeding of approximately 49 acres annually prior to each wet season with a response deadline of June 11, 2026; the County offers a 5% local business preference and a 2% micro-business preference for State-certified contractors, with contract terms of 12 months renewable for up to four additional one-year periods.
