Changsha Weichuang Chemical Co., Ltd supplies ferrous sulphate heptahydrate (FeSO4·7H2O) in the form of a light‑green crystalline powder. The product complies with Chinese standard HG2935‑2000 and is marketed with an iron content of at least 91 % and a FeSO4·7H2O purity of 98 % or higher. Impurities of lead and arsenic are limited to 0.002 % and 0.0003 % respectively. The material is packaged in 25 kg or 50 kg woven plastic bags with an inner polyethylene liner, or in 1000 kg jumbo bags, as required.
In the bulk chemicals market ferrous sulphate heptahydrate is commonly supplied with a moisture content below 0.5 % and a bulk density around 1.4 g cm‑3, which matches the typical range for dry inorganic salts. The powder readily dissolves in water at approximately 30 g per 100 mL at 20 °C, a standard solubility that enables its use in aqueous applications. Storage requirements call for a cool, dry environment away from strong acids or oxidising agents; exposure to moisture can convert the heptahydrate to sodium sulphate, a behaviour noted in the supplier’s handling notes.
The chemical is used in animal feed, water‑treatment processes, disinfectants, rubber and leather manufacturing, as well as in the production of pencils. Importers in the feed, water‑purification and polymer sectors commonly source the material in bulk, negotiating terms such as FOB or CIF based on their logistics network. While the listing does not disclose minimum order quantities or lead times, the supplier indicates willingness to discuss packaging variations, and the product carries a one‑year shelf life when stored correctly.

Before placing an order, importers should request the latest Certificate of Analysis, a Material Safety Data Sheet and any available test reports confirming iron content, impurity limits and moisture level. Verifying the HS code, country of origin and the exact packaging configuration will help avoid customs delays and ensure the product matches the intended application.
Logistics discussions should clarify the preferred Incoterm, whether FOB, CIF or DDP, and confirm the estimated lead time for production and shipment. Payment terms are not disclosed in the listing, so buyers need to negotiate conditions such as a letter of credit or advance payment and ensure they align with their risk management policies.
During the receiving process, a third‑party inspection can verify compliance with the stated specifications, including iron assay and heavy‑metal limits. Retaining the COA, MSDS and any inspection certificates will facilitate quality control and provide documentation required for regulatory approval in the destination market.
