Asia
In Asia, SOP prices moved upward in Q1’26, mainly due to sulfur and sulfuric acid cost pressure. The Middle East supplied nearly half of global seaborne sulfur, and Asia depended heavily on the region, with 63% of its sulfur imports sourced from there. This made Asian SOP producers more exposed to the Strait of Hormuz closure. Daily sulfur shipments of 45,000-50,000 mt through the route were affected, tightening raw material availability. Potash availability offered some balance, but sulfuric acid pressure and freight risk kept SOP offers firm. Downstream demand from compound fertilizer and spring crop application supported procurement, though buyers resisted sharp increases.
Europe
In Europe, SOP prices were stable to firm during Q1’26. The region faced higher import-cost pressure from freight, insurance, energy, and disrupted fertilizer flows through the Strait of Hormuz. The route carried about 14% of global fertilizer trade before the war, making rerouting and shipping delays relevant for European nutrient markets. Downstream demand from horticulture, fruits, vegetables, and chloride-sensitive crops remained steady. Buyers purchased cautiously, but feedstock and logistics risk prevented price weakness.
North America
In North America, SOP prices were comparatively stable in Q1’26. The region had lower direct sulfur exposure to the Strait of Hormuz, as the Americas depend mainly on Canada and the U.S. Gulf Coast for sulfur supply. However, global freight, fuel, and fertilizer-cost pressure still affected replacement costs. Downstream demand remained steady from specialty crops, turf, and chloride-sensitive fertilizer use.
Analyst Insight
According to Procurement Resource, near-term SOP prices may stay firm if sulfur, freight, and insurance costs remain elevated. North America is likely to stay steadier than Asia and Europe unless global feedstock costs rise further.

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.
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.

SOP (Sulfate of Potash) is produced by Decantation process where Langbeinite is treated with a concentrated solution of Potassium chloride which results in the precipitation of potassium sulfate. The precipitated potassium sulfate is then separated by decantation. SOP can also be prepared by Mannheim Process.
