The product offered is Magnesium Sulphate supplied in both Heptahydrate (MgSO4·7H2O) and Monohydrate (MgSO4·H2O) crystalline powder forms. Both grades are reported with a purity exceeding 99 per cent. The material is packaged in 25 kg bags or jumbo bags for bulk export. The supplier states the chemicals have high water solubility suitable for rapid nutrient uptake.
Heptahydrate is commonly used as a soil amendment and foliar fertilizer to correct magnesium and sulfur deficiencies, while Monohydrate is preferred in liquid fertilizer blends and various industrial processes. Typical industry practice limits moisture content to 0.5 per cent or less and expects a bulk density around 1.3 t/m³. The product meets standard specifications for technical grade chemicals used in agro‑chemical and industrial markets. Storage should be in dry, ventilated conditions to preserve quality.
Importers typically source this chemical for agricultural inputs, horticulture, and manufacturing of magnesium‑based products. Trade terms are negotiated per order; buyers should confirm incoterms, payment schedule and lead time directly with the supplier. The supplier’s verification tier is harbour and response metrics are currently unavailable, so further due diligence is recommended.
