Magnesium Sulfate Heptahydrate
The offering is Magnesium Sulfate Heptahydrate, chemical formula MgSO4·7H2O, supplied as a white crystalline solid. Laizhou Longpem Chem., Ltd. provides both food grade material with a purity of 99 %+ and an industrial grade that meets FCC and USP specifications. The product is available in 25 kg woven bags or 1 MT jumbo bags, allowing flexible bulk export shipments.
The heptahydrate contains about 23 % water of crystallisation, which gives it a typical moisture content around that value. It dissolves in water at roughly 24 g per 100 mL at 20 °C, and a 1 % aqueous solution has a pH close to 5.5. Typical bulk density is about 1.6 g cm⁻³ and the material remains stable when stored in dry, sealed containers at ambient temperature. These characteristics align with standard specifications for magnesium sulfate used in agriculture and food processing.
Key applications include use as a dual‑nutrient fertilizer providing magnesium and sulphur, a food additive and processing aid, and a raw material for textile dyeing and pharmaceutical formulations. Buyers such as agro‑chemical manufacturers, food processors and pharma companies often require bulk deliveries and may request certificates of analysis for the chosen grade. Trade conditions, minimum order quantities and Incoterms are not disclosed; prospective importers should verify these details directly with Laizhou Longpem Chem., Ltd.

Sourcing Magnesium Sulfate Heptahydrate from Laizhou Longpem Chem., Ltd. - China Import Guide
Before confirming a purchase, verify Laizhou Longpem Chem., Ltd.’s business registration and obtain a certificate of analysis that details purity, water content and any residual impurities. Ensure the grade you require - food or industrial - is clearly documented and that the packaging size matches your storage and handling facilities.
Discuss preferred Incoterms with the supplier; common options for bulk chemicals from China include FOB Laizhou or CIF Shanghai.
