Overview & Exceptional Quality
Magnesium Sulphate Heptahydrate (0.1–1mm) is a premium-grade, highly water-soluble crystalline compound engineered for demanding agricultural and industrial applications. Manufactured using high-purity raw materials and controlled crystallization processes, this product delivers consistent chemical purity, superior solubility, and absolute physical stability. The uniform fine particle size range of 0.1mm to 1mm ensures rapid, complete dissolution in cold water, making it the ideal choice for liquid formulations, high-tech fertigation, and specialized industrial chemical synthesis where quick dissolution rates are essential.

Nutritional Value & Industrial Versatility
In modern agriculture, magnesium and sulfur are critical secondary nutrients required for maximizing crop yields and quality. Magnesium acts as the central atom of chlorophyll to drive photosynthesis and energy transfer, while sulfur is essential for amino acid, protein, and enzyme synthesis. Thanks to its fine 0.1–1mm crystal structure, this product dissolves quickly without leaving insoluble residue, entirely preventing nozzle clogging in automated drip irrigation, pivot systems, hydroponics, and foliar spray applications. Beyond farming, it serves as an indispensable processing raw material in industrial water treatment, textile dyeing, paper manufacturing, ABS resin production, and detergent synthesis.


Strategic Location & Freight Advantage
Our chemical production facilities are strategically located in Jinghai District, Tianjin, Northern China. Operating in close proximity to Tianjin Port—one of Asia's largest marine shipping hubs—we enjoy direct, seamless highway connections and superior logistical advantages. This prime geographical location significantly reduces inland transportation time, lowers domestic freight costs, and ensures rapid vessel loading, efficient customs clearance, and prompt ocean shipping dispatch for all urgent global export orders.
