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 is a Commodity code covering chemical fertilizers and related agricultural inputs that state and local governments procure for parks maintenance, grounds management, and operational support. Recent solicitations show counties purchasing ammonium sulfate in granular form (typically 50-pound bags) and liquid copper sulfate formulations to support parks departments, maintenance facilities, and turf management operations. Issuing bodies under this code include county governments—specifically Pasco County and Gwinnett County in recent activity—that source these materials through both informal written quotes for smaller quantities and invitation-for-bid processes for larger, multi-year supply arrangements. The work entails straightforward product supply and delivery to specified county maintenance locations, with vendors required to meet standard qualifications including prior experience in similar goods, proper licensing and registration, OSHA-compliant safety documentation, and liability insurance.

Recent activity concentrates in Florida and Georgia. Gwinnett County, Georgia issued an Informal Written Quote (IWQ 130290) in May 2026 for purchase and delivery of 34-0-0 Ammonium Sulfate in 50-pound bags (840 bags total) to 15 county parks and maintenance locations, with quotes due May 20, 2026 and award to the lowest responsive and responsible bidder; contract value was expected below $2,499.99. Pasco County, Florida posted an Invitation for Bid (IFBSP26074) in May 2026 for as-needed herbicides, fertilizers, and pesticides to two county maintenance facilities, with responses due June 16, 2026, covering a multi-year term through September 30, 2029 with optional extensions; the county reserves award authority to single or multiple vendors on a potentially line-item basis. Pasco County also solicited copper sulfate crystals and liquid copper sulfate on an as-needed basis (RFQFP261004) with proposals due June 26, 2026. Local Vendor Preference programs apply to at least one solicitation, though no set-asides for disadvantaged enterprises were designated.
