Wild swings in yellow phosphorus prices have triggered severe cost shocks across the ammonium polyphosphate (APP) industrial chain, squeezing profit margins of flame retardant and fertilizer manufacturers nationwide.
As the core feedstock for thermal-process phosphoric acid and phosphorus pentoxide—key intermediates for high-grade APP—yellow phosphorus has jumped nearly 18% week-on-week amid power curbs and tight supply in southwest China’s major production hubs. Industry data shows every RMB 1,000/ton hike in yellow phosphorus lifts APP production costs by 10% to 15%. Several medium-sized APP producers have suspended low-price spot orders to avoid losses.
APP serves dual demand: halogen-free flame retardants for construction coatings and agricultural water-soluble fertilizers. Downstream buyers with fixed long-term contracts bear most cost inflation, while small chemical formulators face weaker pricing power. Analysts warn persistent yellow phosphorus volatility will delay APP price stabilization until power supply eases and raw material inventory replenishes in late July.

It specializes in various ammonium polyphosphate products, integrating R&D, production and global sales.
