Import Ferrous Sulfate Monohydrate — Buy in Bulk from Supplier in China

The product is ferrous sulfate monohydrate, a blue‑green crystalline chemical with the formula FeSO4·H2O. Its molecular weight is 151.91 g mol‑1 and it carries CAS number 7720‑78‑7 for the monohydrate form. The material appears as pale blue‑green crystals or granules that effloresce in dry air and dissolve readily in water but not in ethanol. Each bulk bag holds 25 kg and is packed in a plastic inner liner inside a compound plastic woven outer bag.

In the fertilizer and feed industry the monohydrate is typically supplied with a purity of 98 % or higher and moisture content below 0.5 % typical. Standard handling requires storage in a dry, well‑ventilated warehouse away from moisture and strong oxidising agents. Bulk density is usually in the range 0.8‑1.0 g cm‑3 typical, and the material is stable at temperatures below 30 °C typical. The product oxidises to basic ferric sulfate when exposed to humid air, so protected packaging is important.

Ferrous sulfate monohydrate is used as a nutrient source for fruit and vegetable crops, as a chromogenic reagent in agricultural testing, and in water‑treatment processes. Importers such as agro‑chemical distributors, feed manufacturers and laboratory suppliers commonly source this grade. The supplier offers 25 kg bags, and buyers should confirm minimum order quantities, preferred Incoterms and payment conditions directly with the company.
