Asia
In Asia, prices for SOP rose consistently throughout Q4'25. Demand from the agricultural sector, especially for fertilizer use, was high throughout the period. Domestic availability in major countries such as India and China was slightly impacted due to a slight reduction in production, while imports were lower compared to the previous year. Southeast Asian ports, including Indonesia and Malaysia, experienced active buying activity as the agricultural sector prepared for the upcoming crop season. Logistical issues from other countries contributed to the supply pressures, which helped sustain the rising prices. However, market participants maintained regular buying activity despite the prices, while inventories were closely monitored to ensure that there were no issues.
Europe
In Europe, prices for SOP remained relatively flat with a general upward trend in Q4’25. Supply was affected by minor disruptions due to domestic production limitations and a slower pace for imports from major exporting countries. Demand for agricultural products was stable as farmers and distributors adopted a cautious approach to purchasing due to high overall fertilizer costs. Although there was some indirect influence on manufacturers from energy costs and feedstock expenses, production was adequate to support regular consumption patterns. Trading activity was consistent, reflecting a balanced market with prices ranging within a tight band.
North America
In North America, SOP prices remained firm in most of Q4’25, although there were indications of weakness at the end of the quarter. The region was heavily reliant on imported material, particularly from Canada, while home production was limited. The recent changes to trade policy, including the elimination of tariffs on potash and other fertilizer types, boosted expectations of a rise in overall supply, which limited the upside in prices. Agricultural and distribution sector demand was robust, although high fertilizer prices did moderate activity to some extent.

Asia
In the third quarter of 2025, SOP prices in Asia showed a mostly stable to slightly declining trend. The demand from farmers and other downstream industries remained moderate, as many buyers were cautious due to economic uncertainties and previous stockpiling.
Imports from other regions faced challenges in attracting buyers, especially where local prices started softening. Traders often tried to move inventory, but actual transactions were limited. Overall, market activity was low, and price movements were small, reflecting a balance between steady supply and moderate demand.
Europe
European SOP markets remained mostly stable during Q3’25. Buyers had already purchased earlier in the year, reducing the need for spot market transactions. With the main fertiliser application season over, immediate demand was minimal. Supply disruptions in other parts of the world did not strongly affect European prices, as inventories were sufficient. Overall, prices either held steady or edged slightly lower, with market sentiment being cautious and consumption staying subdued.
North America
In North America, SOP prices showed minor fluctuations during the quarter. Seasonal agricultural demand provided some support, especially for fall crop applications, but uncertainty in economic conditions and variable costs kept buyers careful. Global supply issues helped maintain a firm pricing environment, yet most purchasers adopted cautious buying strategies. Trading activity remained moderate, and price changes were limited throughout the quarter.
SOP refers to Sulfate of Potash which is a mixture of both potash and sulfur. The general composition for Sulfate of Potash involves 51% soluble potash and about 18% sulfur. It also includes traces of metals like calcium and magnesium. SOP is majorly used as a fertilizer and acts as an excellent source of potassium and sulfur nutrients. It is a low-chloride type of a fertilizer that aids the plants to resist diseases and pests.
