Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O) is a pale green crystalline inorganic salt widely recognized as an effective source of iron. With good water solubility and high bioavailability, it is commonly used in agriculture to correct iron deficiencies in crops and improve plant growth. The compound is also utilized in water treatment processes and as a raw material in chemical manufacturing. Valued for its effectiveness, affordability, and consistent quality, ferrous sulfate heptahydrate serves as a reliable solution across agricultural, environmental, and industrial applications.

We find the right Indian manufacturer for your grade, quantity and target price. Around that, use the services you need:
Before we recommend a manufacturer, we check it in five layers: its documents (COA, SDS, certifications), its business license and IEC status with India’s DGFT, its standing with our industry contacts, an in-person visit to the facility, and its export record.
Want proof that the batch matches its COA before it ships? We collect samples at the factory or port and coordinate testing for purity, grade and contaminants at accredited third-party laboratories. Lab fees are passed through at cost.
We coordinate the paperwork (commercial invoice, packing list, certificate of origin, bill of lading, SDS and COA), compliant packaging and labeling, and the freight forwarder, from export clearance in India to customs entry in the U.S., as your one point of contact.
Our American-led team in India can be at a supplier’s site, check its machinery and real capacity, sit in on negotiations and review documents in person, then report back to you directly, with photos and video from the factory floor.
Going the other way? If you make a specialty chemical or industrial product and want to sell it in India, we provide the on-ground presence and industry network to open that market.
