Import Agricultral Grade Magnesium Sulfate — Buy in Bulk from Supplier in China

Agricultural grade magnesium sulfate from Dalian Sahy International Co., Ltd. is a water-soluble mineral fertilizer supplying magnesium and sulfur, two secondary macronutrients essential for chlorophyll synthesis and enzyme activation in crops. The product is offered as a granular or crystalline solid with high solubility in water, making it suitable for direct soil application, fertigation systems, and foliar sprays. Its agricultural grade designation ensures compliance with typical fertilizer purity standards, with low levels of heavy metals and insoluble impurities.

The magnesium content typically ranges from 9.8% to 10% as Mg, while sulfur is present at approximately 13% as S, with the compound usually marketed as magnesium sulfate heptahydrate (MgSO4·7H2O). Standard agricultural grades often include a white or off-white crystalline form, with particle sizes between 1 mm and 5 mm for granular variants, and a moisture content capped at 2% by weight. These characteristics align with typical industry specifications for magnesium sulfate used in crop nutrition, where uniformity and dissolution rates are critical for field performance.

This input is commonly used in fruit and vegetable production, particularly for crops like tomatoes, potatoes, and leafy greens that exhibit magnesium deficiency symptoms such as interveinal chlorosis. Importers sourcing from Dalian Sahy International Co., Ltd. should confirm packaging options, which may include 25 kg or 50 kg woven bags with polyethylene liners. Bulk shipments are typically quoted under FOB Dalian terms, with lead times dependent on order volume and seasonal demand. Buyers are advised to verify the product’s compliance with local agricultural regulations, as magnesium sulfate specifications can vary by region.

Dalian Sahy International Co., Ltd. operates from Shanlin Street in the Zhongshan District of Dalian, Liaoning Province, China. The company is classified as an imported-tier supplier and holds a harbor trust tier, indicating a baseline level of verification for its export capabilities. Its address and operational base in Dalian, a major port city, suggest logistical advantages for bulk agricultural inputs like magnesium sulfate, with access to maritime shipping routes.

The supplier’s profile does not indicate an active response rate or average response time, which may reflect limited engagement or a focus on established buyer relationships. No additional details such as certifications, production capacity, or client references are provided in the available data, so importers should directly request documentation such as COA (Certificate of Analysis) or SGS test reports to confirm product quality. The company’s specialization appears to include agricultural chemicals, though its exact product range beyond magnesium sulfate is not specified.
