Magnesium Sulfate Heptahydrate 1-3mm (MgSO4·7H2O), universally known as high-grade Epsom salt crystal, is a premium, fully water-soluble mineral compound widely utilized across agricultural, industrial, and personal care sectors. Engineered with a uniform 1–3mm granular size, this formulation eliminates dust issues, resists caking, and delivers superior mechanical handling for automated spreading, dry blending, and liquid dissolving applications.
Primary Applications & Benefits
Agricultural Fertilizer & Fertigation: Serves as a vital source of bio-available magnesium and sulfur. Magnesium acts as the core atom of chlorophyll molecules, directly driving photosynthesis and crop sugar accumulation. The 1-3mm crystal size is ideal for direct soil incorporation, drip irrigation, and NPK fertilizer manufacturing.
Industrial & Technical Processing: Utilized as a specialized dying agent in textile processing, a weighting agent for silk, a tanning assistant in leather refinement, and a coagulant in ABS resin and synthetic rubber production.
Personal Care & Bath Salt: Refined grades act as an essential mineral component in bath salts, muscle relaxation formulations, and therapeutic wellness products.
Why Choose Our 1-3mm Crystal Grade?
Rapid & Complete Dissolution: Dissolves completely in water without leaving sediment or clogging irrigation nozzles.
Dust-Free Granulation: Consistent 1-3mm sizing prevents powder drifting during bulk handling and field application.
Strict Quality Control: Manufactured under ISO-certified processes with heavy metals (Pb, As, Cd) strictly kept below international environmental thresholds.
Packaging, Storage & Logistics
Standard Packaging: 25kg, 50kg PP/PE woven bags with inner liner, or 1000kg/1250kg heavy-duty Jumbo bulk bags.
OEM & Shipping Options: Custom logo printing, palletization, shrink-wrapping, and sea-freight container loading tailored to buyer specifications.
Storage Guidance: Store in a dry, cool, well-ventilated warehouse away from moisture, direct sunlight, and incompatible chemical substances.
Frequently Asked Questions (FAQ)
Q1: What is the benefit of 1-3mm crystal size over powder?
A: The 1-3mm crystal offers better fluid movement, minimal airborne dust, zero caking during long-distance sea transport, and uniform dispersion in soil or liquid mixing tanks.
Q2: Do you offer custom private labeling and COA for import clearance?
A: Yes, full OEM packaging and batch-specific Certificates of Analysis (COA) are provided with every shipment.
