Potassium Sulfate (SOP) Price Trend Q1 2026
The international market of Potassium Sulfate (SOP) experienced a variable price performance in Q1 2026 for Asia Pacific and Europe, depending on the underlying supply and demand fundamentals per each region separately.
On the one hand, SOP prices in the Asia Pacific, primarily China, have grown notably owing to high costs of raw materials like Muriate of Potash and Sulphuric Acid as well as strong prices for energy and constant plant operation rates.
Moreover, ongoing SOP export restrictions have decreased the global supply, which, combined with robust agricultural demand seasonally, has led to price growth by about 4% in March 2026.
On the other hand, SOP prices in Europe, mainly Germany and Belgium, have slightly decreased amid constant feedstock prices, adequate stock levels, and moderate demand growth that prevented additional increases, despite strong production rates in the region.
The geopolitical tensions between USA/Israel and Iran, along with issues at the Strait of Hormuz, have affected trade relations but do not cause supply problems for SOP globally.
