UNSPSC 10171616: Diammonium hydrogenorthophosphate fertilizer

A soluble plant fertilizer which contains a great source of phosphorus and nitrogen

UNSPSC 10171616 Diammonium hydrogenorthophosphate fertilizer is a Commodity code that, based on recent state and local opportunities, encompasses fertilizers and related turf-management chemicals purchased on an as-needed or contract basis by county governments and special-purpose districts for grounds maintenance and athletic facility upkeep. The solicitations show a blend of direct product procurement (granular and custom-blended fertilizers in bags and bulk form) and integrated chemical-application services where fertilizer applications are part of a broader turf-care scope. Issuing bodies include county maintenance operations and parks-and-recreation departments; both recent opportunities come from county governments managing multiple facilities or service areas. Vendors must typically meet minimum business-history requirements (such as three years in operation and two comparable prior contracts), maintain OSHA compliance and Material Safety Data Sheets, and carry comprehensive liability and workers' compensation insurance. Pricing is submitted on a firm or all-inclusive basis, often with bi-annual adjustment provisions tied to the Consumer Price Index.

Recent activity centers in the Southeast. Pasco County, Florida, issued an Invitation for Bid (IFB-SP-26-074) in May 2026 for as-needed herbicides, fertilizers, and pesticides with delivery to two county maintenance facilities and a June 16, 2026 response deadline; the contract period runs through September 30, 2029 with two one-year extension options. The White County Board of Commissioners in Georgia issued a Request for Proposal (PE77037NONST2026) in March 2026 for chemical application services covering three parks and recreation sites, with evaluation weighted toward personnel qualifications, work experience, and project approach (60 of 100 points combined) and an April 2, 2026 deadline. Neither solicitation disclosed a specific budget or award value.
