February 13 News On February 13, the mainstream ex-factory price of 52% powder potassium sulfate rose to 3,950–4,150 yuan/ton, an increase of 50 yuan/ton. Driven by the sharp rise in the prices of raw materials potassium chloride and sulfuric acid, market supply remains tight, leading to a continuous increase in potassium sulfate prices. Chempricehub Analysis: Potassium Sulfate – Bull-Bear Score: 2 The ex-factory price of 52% powder potassium sulfate increased by 50 yuan/ton to 3,950–4,150 yuan/ton, primarily driven by the significant rise in the prices of raw materials potassium chloride and sulfuric acid. Market supply remains tight, and spot prices continue to climb. This reflects strong supply constraints and cost support, providing significant positive momentum for the spot market. Prices are expected to maintain an upward trend in the short term. Potassium Chloride – Bull-Bear Score: 2 As a key raw material for potassium sulfate, the sharp increase in potassium chloride prices directly raises production costs for downstream products, indicating a shortage in its spot market supply or strong demand. This factor supports the spot price of potassium chloride, which is expected to remain strong in the short term, providing significant support to the market. Sulfuric Acid – Bull-Bear Score: 2 The significant rise in sulfuric acid prices, as an essential raw material for potassium sulfate production, drives cost increases for downstream products and reflects tight supply-demand conditions in its own spot market. This supports the spot price of sulfuric acid, which is expected to remain on an upward trend under the support of raw material costs, forming a significant positive factor.
