According to China Chemical News, since November 2025, the phosphate chemical market has exhibited a stark contrast between extremes.

Industrial-grade monoammonium phosphate (MAP, 73% content) has taken center stage, driving a frenzied price surge. Mainstream transaction prices have firmly settled between 6,300 and 6,600 yuan per ton, with some premium quotes nearing the 6,500 yuan threshold. On November 12 alone, prices jumped 2.46%. Coupled with widespread corporate reluctance to sell, the industry is undergoing profound restructuring.

Meanwhile, other product categories showed subdued performance: the average price for 55% granular ammonium phosphate stood at 3,440 yuan, up only 7 yuan (0.20%) from the previous trading day. The average price for diammonium phosphate remained unchanged at 3,596 yuan. Currently, sulfur prices remain stable at elevated levels, nearing the 4,000 yuan threshold. Phosphate fertilizer plants face significant cost pressures, with some enterprises narrowly raising new order quotations. However, due to market uncertainty, most plants have suspended quotations and contracts, shifting focus to fulfilling existing orders. Downstream demand shows divergence, as compound fertilizer enterprises maintain a strong wait-and-see attitude, limiting new order transactions.

As a core phosphorous chemical product, industrial-grade monoammonium phosphate (MAP) bridges upstream raw materials like sulfur and phosphate rock with two major downstream sectors: new energy and agriculture. Its price increase will inevitably impact the market.

In the short term, the upward price trend is expected to persist. Sulfur prices are unlikely to see significant fluctuations in the near term, providing cost support for industrial-grade MAP. Coupled with the sustained release of incremental demand from the lithium iron phosphate industry—projected to grow by over 30%—the tight supply-demand balance suggests mainstream transaction prices could surpass the 6,600 yuan threshold.

Industry insiders suggest monitoring three key variables in the medium to long term: First, whether supply of raw materials like sulfur improves—increased international production capacity or imports could alleviate cost pressures. Second, whether new energy demand growth meets expectations—the pace of demand release in energy storage and power battery sectors directly determines price ceilings. Third, policy regulation trends—excessive price increases may trigger regulatory measures to stabilize the market.

For companies across the supply chain, it is crucial to accurately gauge shifts in demand structure. Downstream new energy enterprises can mitigate price hike risks by securing long-term contracts in advance. Agricultural sector players, meanwhile, should manage inventory levels to counter operational pressures stemming from weak demand.
