1. Basic Information
Product Name: Magnesium Sulfate/ Magnesium SulfateAnhydrous
Chemical Name: Magnesium Sulfate/ Magnesium Sulfate Anhydrous
Product Introduction: This product is high-purity anhydrous magnesium sulfate refined by high-temperature dehydration process, appearing as pure white powder or granules. With no crystal water, it has higher magnesium and magnesium oxide content than magnesium sulfate monohydrate and heptahydrate, with excellent moisture absorption and drying performance. Divided into industrial grade and agricultural fertilizer grade, it has stable physical and chemical properties, fast water solubility and extremely low impurities. It has dual purposes of industrial drying & adsorption and agricultural magnesium & sulfur supplement, suitable for foreign trade export, precision chemical industry and high-end planting. With lower storage and transportation costs, it is a high-concentration bulk raw material for magnesium and sulfur elements.

Executive Standard: Industrial Grade: HG/T 2680-2009; Agricultural Fertilizer Grade: GB/T 26568-2011
3. Product Core Characteristics
Extremely High Nutrient Concentration: Crystal water-free structure, magnesium oxide and elemental magnesium content far higher than magnesium sulfate monohydrate and heptahydrate, lower feeding dosage for the same magnesium supplement effect, greatly saving transportation and storage costs.
Strong Moisture Absorption & Drying Performance: Excellent water adsorption capacity, special high-efficiency desiccant and adsorbent for chemical industry, suitable for liquid phase dehydration and material moisture-proof working conditions.
Excellent Dissolution Performance: Extremely fast dissolution in water, clear solution without impurity residue, suitable for high-end water-soluble fertilizer, foliar fertilizer preparation and industrial liquid phase batching.
Dual-Grade Compliance & Adaptability: Clear classification of industrial and agricultural grades, meets national and overseas industry standards, complete qualifications, supports global foreign trade customs clearance and shipment.
Stable Batch Quality: Produced by automatic high-temperature dehydration and purification production line, constant nutrient and impurity indexes for each batch, suitable for standardized mass production batching in factories.
