Natural kieserite (magnesium sulfate monohydrate, MgSO.H2O is a premium, mineral-derived fertilizer and industrial raw material valued for its high concentration of water-soluble magnesium and sulfur. Processed under strict quality control standards, our kieserite provides an optimal balance of magnesium (Mg≥16%, equivalent to Mg≥27%) and sulfur (S≥20%), making it an indispensable soil amendment for agricultural crop production and industrial applications.
As a leading wholesale supplier and direct chemical exporter, we offer consistent batch quality, low impurity levels, and flexible shipment terms to help commercial buyers optimize their raw material procurement.
Chemical Formula: MgSO.H2O (Natural Mineral Origin)
Appearance: Off-white to light gray powder or free-flowing uniform granules (2.0 mm – 4.0 mm).
High Nutrient Concentration: Delivers fully bioavailable, water-soluble magnesium and sulfur without altering soil pH balance.
Physical Stability: Low moisture absorption profile prevents rapid caking, ensuring superior shelf life and smooth handling through industrial hoppers and automated spreading equipment.
Understanding the diverse kieserite uses across global markets helps procurement teams select the proper grade and mesh size for specific applications:
Commercial Agriculture & Broadacre Crop Nutrition:
One of the primary kieserite uses is providing an immediate supply of bioavailable magnesium and sulfur to high-yielding cash crops, including palm oil trees, rubber plantations, citrus orchards, corn, and potatoes. Unlike synthetic fertilizers, kieserite dissolves gradually to sustain root uptake, drive chlorophyll formation, and improve nitrogen assimilation efficiency.
Bulk Fertilizer Blending (NPK Compounds):
Granular kieserite (2–4 mm) is engineered for bulk mechanical blending with urea, DAP, and potassium chloride. Its high granule crushing strength prevents segregation and dust generation during transport and field application.
Soil Conditioning for Acidic Soils:
Because it supplies essential magnesium without increasing soil alkalinity, kieserite is heavily used in tropical, acidic, or heavily leached soils where standard liming agents are ineffective or undesirable.
Industrial Processing & Animal Nutrition:
Secondary kieserite uses include serving as an industrial precursor in chemical processing, wastewater coagulation, and feed-grade magnesium supplementation in livestock mineral blocks.
When calculating your landed kieserite price for containerized ocean freight, evaluating direct-from-factory sourcing is essential to maintaining profit margins. Key factors influencing the overall kieserite price include physical form (powder vs. 2–4 mm granule), purity grade, seasonal agricultural demand, and packaging specifications.
Bulk Packaging Options: Supplied in standard 25 kg / 50 kg PP woven bags with PE inner liners, or 1000 kg / 1250 kg jumbo super sacks fitted with discharge spouts.
Shipping & Trade Terms: We offer competitive FOB, CFR, CIF, and DDP shipping terms directly from major export ports with full container load (FCL) availability.
Quality Documentation: Every shipment includes a Certificate of Analysis (COA), Safety Data Sheet (SDS), and REACH compliance details to ensure seamless customs clearance.
