Magnesium Sulphate Price Trend Q4 2025
In the 4th quarter 2025, Magnesium Sulphate prices increased by 4% from the previous quarter. The increase reflects the stability of the market, without disruption to the supply/demand balance. Ongoing strong agricultural demand has driven the consumption levels for Magnesium Sulphate through fertilizer applications to manage soil nutrients, as well as through foliar applications (sprays) in horticulture, and to grow both fruit and vegetable crops. Key regions experienced seasonal crop cycles that helped to replenish nutrients and provide balanced fertilizer applications. There has been stable supply where manufacturers have been matching production to demand, which helped to keep inventories at a minimum level and provided sufficient supply. All feedstocks (magnesium oxide, magnesium carbonate, and sulphuric acid) remained readily available; however, the small increase of input prices due to the pressure on producer price levels has also created an upward price trend.
India: Magnesium Sulphate Domestic Prices Ex-Chennai, India; Grade – 99% Magnesium Sulphate Heptahydrate
The price trend of Magnesium Sulphate in India during Q4 2025 showed stable-to-firm conditions in market prices with a slight increase each quarter of 2.0% compared to previous quarter’s price. Continued agricultural usage associated with fertilizer blending, horticulture, and foliar nutrition sustained stable levels of Magnesium Sulphate usage. Domestic producers reported consistent production volumes with sufficient access to feedstock during this period. However, by December 2025, Indian Magnesium Sulphate prices decreased by 3.0% due to year-end inventory adjustments resulting from lower buyer purchasing than previously observed (and corresponding to prior quarters). Overall, the close of Q4 2025 will feature balanced supply and demand and stability in agricultural usage.
China: Magnesium Sulphate Export prices Qingdao, China; Grade – 98% Magnesium Sulphate Anhydrous
For Q4 2025, the price trend of Magnesium Sulphate prices in China witnessed a decline. Prices decreased by 3% when measured quarter-on-quarter. This decrease has been due to weaker buyer sentiment and ample supplies. The agricultural demand for soil nutrient corrections and for foliar applications remained stable but without much enthusiasm. Producers maintained balanced operating rates due to an adequate amount of feedstock throughout the entire quarter. Overall, during December 2025, the prices for Magnesium Sulphate within China did recover slightly, with a 2% increase to be attributed to some minor short term inventory replenishment and slight increases in feedstock costs. Overall, during the period there has been a general soft/balanced tone in the pricing of Magnesium Sulphate products driven by both volume discipline (supply discipline) by producers and stable agricultural end-user demand for Magnesium Sulphate products.
