China, the United States, and Germany are the leading exporters of magnesium hydroxide, collectively accounting for over 60% of global exports in recent years; major importers include South Korea, Japan, and Mexico, driven by demand from flame-retardant and wastewater treatment sectors. Global magnesium hydroxide prices have remained relatively stable amid steady export volumes from top suppliers, with no significant shifts in country-level trade shares observed between 2022 and 2024.
Magnesium hydroxide is a white, odorless, crystalline solid that occurs naturally as the mineral brucite and is practically insoluble in water. It is an inorganic base and metal hydroxide, thermally decomposing above 350 °C rather than melting or boiling at standard conditions. It serves primarily as a flame retardant and smoke suppressant in polymer formulations—including polyolefins, PVC, and engineering plastics—and as a neutralizing agent and pH adjuster in wastewater treatment. It is also used as an intermediate in the production of magnesium oxide and as an active pharmaceutical ingredient in antacid and laxative preparations. Typical application areas include flame-retardant cables, construction materials, pharmaceuticals, and environmental remediation.
