US Di Ammonium Phosphate Prices Fall 0.63% in late May 2026, Seasonal Slowdown Hit the Market

Di Ammonium Phosphate (DAP) prices in the USA eased in late May, ending the month with a firmer underlying tone than at the start. Early May demand was pressured by a spring cooldown, while mid-May tightness in DAP availability briefly supported valuations. By late May, softer ammonia and sulfur costs alongside import arrivals relieved bottlenecks and cooled activity. May unfolded as two phases: a mid-month rally driven by constrained flows, followed by late-month easing as offers and freight dynamics normalized. Demand was mixed across sectors, with agriculture the primary driver of DAP consumption but softening toward month-end as farmers and distributors trimmed purchases after peak application, leaving higher on-farm inventories. Export channels supported sentiment mid-month amid tighter shipments to Latin America and India, while wholesalers retrenched on DAP replenishment. Upstream dynamics mattered: feedstock costs moved in a mixed pattern, lifting production costs mid-month before easing later. Imports and competitive offers improved landed availability, softening near-term upside. The outlook points to stability to modest firmness, contingent on planting activity and feedstock trends.
