Magnesium Sulphate Heptahydrate from Langfang Huinuo Fine Chemical Co., Ltd. is a white crystalline compound with the chemical formula MgSO4·7H2O and CAS number 10034-99-8. This water-soluble inorganic salt is offered in industrial and feed grades, with typical purity above 99% as stated by the supplier. The product is designed for applications requiring soluble magnesium and sulfur, delivered in a stable, easy-to-handle form.
The material is a standard heptahydrate form of magnesium sulphate, commonly used in agriculture to correct soil deficiencies in magnesium and sulfur, which are essential for plant growth. In animal feed, it serves as a mineral supplement to support livestock health. The crystalline structure ensures high solubility in water, making it suitable for liquid formulations in textile processing and pharmaceutical manufacturing. Industrial grades typically meet standard purity thresholds for such uses, while feed grades adhere to tighter controls for animal nutrition.
Primary buyers include agricultural cooperatives, feed manufacturers, and chemical distributors sourcing bulk quantities for export. The product is packed in 25kg bags or 1MT jumbo bags, optimized for containerized shipping from China. Importers should confirm packaging suitability for their logistics chain, as well as compliance with local regulatory standards for the intended application. The granular form allows for precise dosing in both solid and liquid systems, reducing waste and improving efficiency in end-use scenarios.

Before ordering magnesium sulphate heptahydrate from Langfang Huinuo Fine Chemical Co., Ltd., verify the product’s compliance with your country’s regulatory standards for the intended use, whether agricultural, feed, or industrial. Request a Certificate of Analysis (CoA) to confirm purity, magnesium, and sulfur content, as well as the absence of contaminants. Ensure the supplier can provide documentation for any claims, such as typical purity above 99%, to avoid discrepancies upon delivery.
Confirm logistics details, including packaging options (25kg bags or 1MT jumbo bags) and their suitability for your handling and storage infrastructure. Discuss Incoterms such as FOB or CIF to clarify responsibilities for shipping, insurance, and customs clearance. Lead times for containerized exports from China should be agreed upon in writing, accounting for production schedules, port congestion, and seasonal demand fluctuations.
For quality assurance, arrange for pre-shipment inspection of the crystalline structure, particle size, and solubility. Request samples for lab testing to validate performance in your specific application. Check that the documentation includes batch numbers, manufacturing dates, and test reports for each shipment. This ensures traceability and helps resolve any issues that may arise during customs or end-use processing.
