Magnesium Sulfate Heptahydrate
Weifang Sheng Xing supplies Magnesium Sulfate Heptahydrate (MgSO4·7H2O) as a water-soluble crystalline compound, available in both industrial and food-grade variants. The industrial grade is suited for water treatment, textile dyeing, and fermentation, while the food-grade version conforms to FCC standards for dietary supplements and food processing. The product is exported from Lingang Industrial Park in Weifang, Shandong, China.
As a key fertilizer, this compound corrects magnesium and sulfur deficiencies in soils, particularly in crops like tomatoes, potatoes, and leafy greens. The heptahydrate form ensures rapid dissolution and uptake, with typical applications including foliar sprays and soil drenches. In industrial settings, its solubility and hygroscopic nature make it valuable for chemical synthesis and wastewater treatment.
Buyers include fertilizer blenders, food ingredient manufacturers, and chemical processors sourcing bulk quantities. Packaging options range from 25kg bags to big bags and bulk containers, with global supply stability from China’s production hubs. Confirm the grade specification, as food-grade material requires stricter controls on impurities like heavy metals and microbial content.

Sourcing Magnesium Sulfate Heptahydrate from Weifang Sheng Xing - China Import Guide
When sourcing from Weifang Sheng Xing, verify whether the material is natural brine-derived or synthetically produced, as this can impact trace mineral content and suitability for organic certification. Request a CoA for each batch to confirm purity, impurity levels, and compliance with your intended use, particularly for food-grade applications.
Logistics should prioritize moisture-proof packaging, as magnesium sulfate heptahydrate is hygroscopic. Confirm whether the supplier can provide fumigation-free containers for markets with strict quarantine rules. Common Incoterms include FOB Weifang or CIF to major ports, with payment terms such as T/T or L/C. Lead times may vary based on order volume and season.
Quality checks upon receipt should include testing for solubility, pH, and particle size distribution. For food-grade material, additional tests for heavy metals, microbial content, and compliance with FCC or EU standards are essential. Ensure all documentation, including CoA, MSDS, and compliance certificates, is provided and reviewed before release for use.
