China and the United States are the leading exporters of magnesium sulfate heptahydrate, accounting for a substantial share of global supply, while India, Germany, and Brazil represent the largest importers. Magnesium sulfate heptahydrate prices have remained relatively stable amid steady cross-border flows. Export volumes from China have expanded modestly over the past two years, while Indian imports have grown consistently, reflecting increased domestic demand in pharmaceutical and agricultural applications.
Magnesium sulfate heptahydrate is a white, crystalline, odorless solid that is highly soluble in water and non-volatile; it decomposes upon heating rather than melting, losing water of hydration progressively above 150 °C. It is an inorganic hydrated salt, classified as a magnesium salt and a common source of magnesium ions in aqueous systems. Industrially, it serves as a precursor for magnesium oxide, catalysts, and other magnesium-based compounds, and is widely used as a coagulant in textile processing and as a nutrient supplement in agriculture and animal feed. Its primary application areas include agrochemicals (e.g., foliar magnesium fertilizers), pharmaceuticals (e.g., laxative formulations and topical preparations), and the production of ceramics, dyes, and paper additives.
