UNSPSC 12352314: Ammonium sulphate

An inorganic chemical compound with the formula (NH4)2SO4 commonly used as a fertilizer. It contains 21% nitrogen as ammonium ions and 24% sulfur as sulfate ions.

UNSPSC 12352314 Ammonium sulphate, a Commodity code, captures state and local purchases of chemical compounds and specialty fertilizers for parks maintenance, water treatment, and turf management. Recent solicitations show counties and municipalities buying ammonium sulfate and related sulfate-based compounds in bulk form—34-0-0 ammonium sulfate in 50-pound bags for parks and recreation departments, aluminum sulfate (alum) solutions for water reclamation facilities, and copper sulfate crystals for specialized applications. The issuing bodies are primarily counties and municipalities: Gwinnett County, Georgia; Pasco County, Florida; the City of Tallahassee, Florida; and White County, Georgia. These jurisdictions solicit under the code through informal written quotes (IWQs), invitations for bid (IFBs), and requests for proposal (RFPs), often on indefinite-quantity or requirements-contract bases. Vendors must typically demonstrate three or more years of relevant experience, provide multiple project references, maintain required insurance coverage (general liability typically $1 million to $2 million per occurrence), comply with state E-Verify and drug-free workplace requirements, and submit Material Safety Data Sheets and certificates of conformance with deliveries.

Recent activity concentrates in Georgia and Florida. Gwinnett County, Georgia issued an IWQ (PE77023NONST2026000000600) due May 20, 2026 for 840 bags of 34-0-0 ammonium sulfate distributed across 15 county parks and maintenance locations, with award to the lowest responsive and responsible quote and payment within 30 days of delivery. Pasco County, Florida posted an IFB (IFBSP26074) due June 16, 2026 for herbicides, fertilizers, and pesticides on an as-needed basis with a contract term through September 30, 2029 and optional two-year extensions, allowing bi-annual CPI adjustments and local vendor preference consideration. The City of Tallahassee issued an IFB (045-26-RM) due March 31, 2026 for bulk liquid aluminum sulfate at approximately 900 dry tons annually over a three-year initial term with optional years four and five, with anticipated awards to the two lowest cost responsive bidders; the city offers local vendor preference for vendors with a permanent place of business in specified counties for at least six months prior to bid submission. White County, Georgia solicited an RFP (PE77037NONST2026000000022) due April 2, 2026 for chemical application services covering seasonal turf treatments at three parks and recreation facilities, evaluated on company background, personnel qualifications, work experience, project approach, and pricing.
