STPP Price Trend 2026: Global Price Trends, Forecast, Chart, Prices & Index Analysis

The STPP Price Trend in the second quarter of 2026 showed a clear upward movement in the global market, followed by a gradual slowdown toward the end of the quarter. 

Sodium Tripolyphosphate (STPP) prices increased by around 11% to 17% compared with the first quarter, mainly because of limited phosphate rock supply, higher transportation costs, and uncertainty caused by geopolitical tensions between Iran and Israel. 

However, the market began to show signs of improvement in May and June as shipping conditions became more stable and raw material availability improved. This change affected buyers, importers, exporters, and manufacturers across several countries. 

The second quarter offered an important lesson for the chemical market: prices do not depend only on demand, but also on raw material costs, transportation, supply availability, and the overall global situation.
