Import Ferrous Sulphate — Buy in Bulk from Supplier in China

Ferrous sulphate offered by Shenzhen Changlong Technology Co., Ltd. is presented as a high‑purity iron(II) sulfate suitable for diverse industrial and agricultural processes. The supplier states that the product meets the minimum purity level required by industry standards, though exact percentages are not disclosed in the listing. The compound is identified by the standard CAS number 7782‑63‑0 and is typically supplied as a light‑green crystalline powder. Packaging options are described in general terms, with bulk freight or 25 kg bag sizes commonly used for similar chemicals.

Typical grades of ferrous sulphate heptahydrate achieve a purity of 98 % or higher, contain around 19.5 % iron by weight and dissolve at approximately 45 g per 100 mL of water at 20 °C, facilitating easy integration into formulations. Standard moisture content for the product is kept below 5 % to ensure stability during storage. The material is non‑flammable and should be kept in a cool, dry environment away from strong oxidising agents. Industry practice also recommends sealing containers to protect against moisture ingress.

Key markets for this chemical include water‑treatment plants, fertilizer manufacturers and metal‑processing facilities that rely on iron supplementation. Prospective buyers are encouraged to request the supplier’s latest ISO or SGS inspection reports, as the listing mentions compliance with these certifications but provides no documents. As the response rate is currently recorded as zero, importers should verify communication channels and negotiate payment terms such as T/T or L/C before finalising a contract. Clarifying the preferred incoterm - FOB, CIF or DAP - will help align logistics expectations.

Shenzhen Changlong Technology Co., Ltd. is located at No. 18 Lanshui 3Rd Area, Longxin Community, Longgang Street, Shenzhen, 518100, China. The firm is classified as an imported supplier and carries a harbour trust tier, indicating a moderate verification level.

The public profile does not disclose a response rate or average response time, and the listing does not specify production capacity or ownership details. Changlong focuses on supplying chemical commodities and notes compliance with ISO and SGS standards, though specific certificates must be obtained from the supplier.
