NIGP 33540: Fertilizers, Liquid, All Types (Except Anhydrous Ammonia)

NIGP 33540 Fertilizers, Liquid, All Types (Except Anhydrous Ammonia), an Item code, covers liquid and specialty fertilizer products that state and local governments procure for agricultural operations, turf maintenance, and grounds management—including zinc fertilizer, copper sulfate in crystal and liquid forms, and custom-blended formulations supplied on both firm and as-needed bases.

State agencies, counties, and cities drive activity under this code. The Texas Department of Criminal Justice, the State of Texas, Pasco County, Florida, the City of Bradenton, and the White County Board of Commissioners have all posted solicitations in the past three months. Pasco County appears as a repeat buyer, issuing separate RFQ and IFB notices for fertilizer products and as-needed herbicide-fertilizer-pesticide bundles. Work ranges from straightforward supply contracts with fixed schedules to integrated service packages combining chemical application with turf management oversight. Requirements commonly include Material Safety Data Sheets, minimum supplier tenure (typically three years in business with comparable contract history), F.O.B. destination pricing with freight prepaid, and compliance with Florida E-Verify or Georgia Security and Immigration Compliance Act provisions depending on jurisdiction.

Recent activity concentrates in Texas and Florida. The State of Texas issued an IFB for zinc fertilizer (due July 24, 2026); Pasco County solicited large copper sulfate crystals and liquid copper sulfate on an as-needed basis (RFQ due June 26, 2026) and herbicides, fertilizers, and pesticides with two delivery sites and CPI-U-indexed bi-annual pricing through September 30, 2029 (IFB due June 16, 2026). The City of Bradenton procured golf course chemicals and fertilizers for River Run Golf Links with an estimated annual spend of $140,000 and delivery requirements between 5:00 a.m. and 2:00 p.m. twice weekly. The White County Board of Commissioners in Georgia issued an RFP for chemical application services across three parks and recreation facilities, evaluated on company background, personnel qualifications, work experience, project approach, and pricing, with a pre-proposal meeting on March 12, 2026 and sealed proposals due April 2, 2026.
