Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The offering is ferrous sulfate heptahydrate, chemically defined as FeSO4·7H2O with a molecular weight of 278.02 g mol⁻¹. The product appears as pale blue‑green crystals or granules that are efflorescent in dry air and readily oxidise in moist conditions to a brown‑yellow basic ferric sulfate. It is soluble in water and insoluble in ethanol, matching standard solubility data for the heptahydrate form. The CAS number for this grade is 7782‑63‑0.
In the food‑ingredient market, this heptahydrate is used as a nutrient source and as a chromogenic reagent for fruits and vegetables. Typical industry grades are classified by purity, with ACS‑grade material usually exceeding 98 % FeSO4·7H2O and meeting strict limits on heavy‑metal contaminants. The product is commonly stored in dry, ventilated warehouses to prevent moisture uptake, and it is packaged in inner plastic bags within a compound woven outer bag, each bag weighing 25 kg.
Buyers such as food‑processing firms, agricultural supplement manufacturers and laboratory reagent distributors often require this chemical in bulk. The supplier does not disclose a minimum order quantity, so importers should confirm package counts and any bulk‑handling options. Shipping is performed in sealed bags, and purchasers are advised to verify the exact Incoterm, payment method and any required certifications before finalising the transaction.

Prior to placing an order, verify the supplier’s harbour trust tier and request recent trade references or third‑party inspection reports. Confirm the exact minimum order quantity, packaging details and whether bulk‑handling options are available. Request a material safety data sheet (MSDS) and a certificate of analysis that includes purity, moisture content and heavy‑metal limits to ensure compliance with your specifications.
Shipping for ferrous sulfate heptahydrate typically uses sea freight in 25 kg bags, but larger volumes may be consolidated into bulk containers. Importers should clarify the preferred Incoterm, expected lead time from production to dispatch, and any required pre‑payment or letter‑of‑credit arrangements. Because the supplier’s response rate is currently recorded as zero, allow additional time for communication and confirmation of trade terms.
On arrival, perform a visual inspection for colour change or moisture damage, and conduct moisture content testing to confirm it remains below typical 0.5 %. Request a certificate of analysis that details iron assay, heavy‑metal content and solubility test results. Implement a random sample inspection protocol before releasing the material for use in food‑ingredient or laboratory applications.
