UNSPSC 10171609: Silica phosphate fertilizer

A chemical fertilizer that contains phosphorus acid, silicic acid, magnesia and lime. It is used to reduce insect damage and add vitality plant root systems.

UNSPSC 10171609 Silica phosphate fertilizer (Commodity) shows minimal recent direct activity under the code's narrow specification, with the vast majority of state and local opportunities soliciting broader fertilizer categories including ammonium sulfate, DAP, potash, urea, and custom blends rather than silica phosphate specifically. The work state and local governments actually buy under this code tier encompasses turf and landscape fertilization for parks and recreation facilities, agricultural inputs for research and operational farms, and supporting chemical applications across multiple product lines. Issuing bodies include county purchasing departments (Gwinnett County Georgia, Pasco County Florida, Pinellas County Florida, Palm Beach County Florida), state agricultural departments (Illinois Department of Agriculture), and county boards of commissioners (White County Georgia). Counties appear as repeat buyers across calendar year 2026, with jurisdictions in Florida and Georgia showing the most recent posting activity.

Geographic concentration runs across Florida, Georgia, and Illinois, with activity posted between January and May 2026. Representative recent opportunities include Gwinnett County, Georgia issuing an Informal Written Quote (IWQ 130290) on May 13, 2026 for 840 bags of 34-0-0 Ammonium Sulfate due May 20, 2026; Pasco County, Florida posting an Invitation for Bid (IFB-SP-26-074) on May 12, 2026 for as-needed herbicides, fertilizers, and pesticides with response due June 16, 2026; the Illinois Department of Agriculture conducting small purchase procurements with sole source conditions for fertilizers, seeds, and application services at state research farms with two-to-three-day response windows in March 2026; and Palm Beach County, Florida maintaining a standing pre-qualified vendor list (RPQ68023003CR13) for chemicals and fertilizer supply with an anticipated sixty-month contract value of $900,500. The code shows little direct silica phosphate activity; recent opportunities predominantly require suppliers to provide conventional NPK and micronutrient fertilizers, application services, and integrated chemical supply across multiple product categories rather than specialized silica phosphate formulations alone.
