Sodium Tripolyphosphate (STPP) Price Trend Q3 2025
In Q3 2025, the global Sodium Tripolyphosphate (STPP) price trend continued an upward trajectory, driven by a combination of rising raw material costs, firm demand from the detergent and ceramics industries, and regional supply tightness. The STPP price increased across key export hubs such as China and other Asian countries, supported by higher input costs for phosphorus-based chemicals and continued energy price volatility. While environmental regulations and production curbs in China further constrained output, contributing to tighter availability in the international market.
By September, the price in many importing regions, including Southeast Asia, Africa, and South America, had risen steadily, reflecting higher FOB values and, in some cases, increased shipping costs. With no immediate relief in upstream pricing or significant capacity additions expected, the global STPP price trend remains bullish heading into Q4, especially if demand holds firm in the cleaning and water treatment sectors.
