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 sees minimal recent state and local procurement activity. The code nominally covers a specific phosphate fertilizer product, but recent state and local solicitations tagged under this code do not reflect traditional fertilizer purchasing. Instead, the activity centers on specialized phosphorus-removal systems and broad-based herbicide, fertilizer, and pesticide procurement where diammonium phosphate may be one component among many. The City of Orem, Utah solicited design, manufacture, and delivery of a complete phosphorus control system for wastewater treatment via RFP (PROJECTNO230904, due October 16, 2026), in which phosphate chemistry plays a role in struvite precipitation but the primary deliverable is engineered equipment rather than a fertilizer product. Pasco County, Florida issued an IFB (IFB-SP-26-074, due June 16, 2026) for herbicides, fertilizers, and pesticides on an as-needed basis, where diammonium phosphate would be one potential fertilizer formulation among custom-blended and granular product options. The issuing bodies using this code span municipal utilities (wastewater treatment) and county maintenance operations, reflecting fragmented demand across different government functions.

The recent opportunities show activity in Utah and Florida only. The Orem wastewater project represents a specialized, one-time systems integration engagement with an EPA-funded facility improvement, requiring equipment design, factory testing, installation support, and operator training with a six-month delivery window and $1,000 per day liquidated damages for delays. The Pasco County procurement is a standing supply contract running through September 30, 2029 with optional two-year renewals, covering deliveries to two facilities with strict packaging and handling requirements (bags no larger than 50 pounds, Monday–Friday delivery windows, OSHA MSDS compliance, and F.O.B. Destination pricing). No budget figures were disclosed for either opportunity. Vendors pursuing the Orem project must demonstrate phosphorus-removal technology expertise and systems integration capability; those pursuing Pasco County must meet three years of similar business experience, hold two prior comparable contracts, maintain insurance ($2 million general liability minimum), and comply with Florida's E-Verify and drug-free workplace requirements. The code shows limited activity overall and does not align well with traditional diammonium phosphate fertilizer sales channels.
