Why is monoammonium phosphate priced higher than diammonium phosphate in China's export market?

Worth watching the export side too. Baltic MAP FOB averaged 651 USD/mt in 2025, roughly 1,300 yuan/mt above domestic levels, but with exports suspended until after spring 2026, that arbitrage is locked out. Once policy loosens, the overseas premium could reset domestic price expectations quickly.

How are sulfur and phosphate rock costs driving monoammonium phosphate producers into losses?

The utilization number understates the pain. Many of the plants still running are doing so to hold market share and honor prepaid orders, not because the economics work. If sulfur stays elevated into the second half, expect a sharper wave of permanent exits among merchant converters rather than temporary maintenance.

Can China's monoammonium phosphate capacity still absorb new battery-grade demand?

The bottleneck is grade, not tonnage. Battery-grade and industrial-grade MAP require purification steps that most fertilizer lines cannot easily add. So even with surplus fertilizer-grade capacity, the high-purity segment stays tight and commands a premium — that gap is where the real investment case sits.

Overview

Ammonium dihydrogen phosphate (monoammonium phosphate, MAP, CAS 7722-76-1) is a white crystalline solid with a density of 1.02 g/mL at 20°C, a melting point of 190°C (dec.), and water solubility of 368 g/L at 20°C. It is a key phosphate compound used primarily as a fertilizer and as an intermediate in downstream chemical applications.

Fertilizer: a major source of nitrogen and phosphorus for crops, commonly used in compound fertilizer production.
Industrial: a high-purity grade (≥96% NH4H2PO4) used in flame retardants, water treatment, and as a raw material for producing iron phosphate and lithium iron phosphate for batteries.
Food: a food-grade variant is used as a leavening agent and nutrient supplement.

China's production is dominated by fertilizer-grade MAP (55–60% purity), with industrial-grade capacity concentrated among a few large producers. The industry faces cost pressures from rising sulfur and phosphate rock prices, with policy emphasizing domestic supply security over exports. Industrial-grade MAP is a strategic link to the new-energy battery supply chain.

Key domestic producers:
Yuntianhua – leading phosphate fertilizer and industrial-grade MAP producer.
Chuanfa Longmang – largest industrial-grade MAP producer, supplying battery material makers.
Chuanheng Co. – industrial-grade MAP for firefighting and battery applications.
Xinyangfeng – major MAP capacity with plans to expand industrial-grade output.
