Ferrous sulphate heptahydrate price manufacturers

When sourcing Ferrous Sulphate Heptahydrate, the purity level (typically 98% or higher) is the most critical factor. You must verify the Iron (Fe) content, which should be approximately 19.7% to 20% for the heptahydrate form. Ensure the product is free-flowing and light green in color; a brownish tint often indicates oxidation to ferric iron, which reduces effectiveness. Always request a Certificate of Analysis (COA) for every batch to confirm levels of heavy metals like Lead (Pb), Arsenic (As), and Cadmium (Cd), especially if used in water treatment or animal feed.

The 'Price' of Ferrous Sulphate Heptahydrate is heavily influenced by its grade. For Water Treatment, focus on its role as a coagulant and flocculant for phosphorus removal. In Agriculture, it serves as a micronutrient fertilizer to correct iron chlorosis; here, solubility and particle size are key. For Cement Manufacturing, it is used as a Chromium (VI) reducer, requiring specific moisture content levels to prevent caking in silos. Ensure the supplier provides the correct mesh size (granular vs. powder) suited for your specific machinery.

Buyers must ensure the product meets ISO 9001 for quality management. If the product is intended for the European market, REACH registration is mandatory. For water treatment applications, look for NSF/ANSI 60 certification. Because it is a chemical substance, the supplier must provide a comprehensive Material Safety Data Sheet (MSDS) that aligns with the Globally Harmonized System (GHS) to ensure safe handling and legal customs clearance.

Ferrous Sulphate Heptahydrate is efflorescent, meaning it loses water molecules in dry air, and it is also hygroscopic. To maintain quality and prevent caking, it should be packed in moisture-proof PP/PE bags (25kg or 1000kg jumbo bags) with an inner plastic liner. Palletization and shrink-wrapping are highly recommended for cross-border shipping to prevent bag breakage and exposure to humidity, which can lead to oxidation and clumping, rendering the product difficult to use in automated systems.

The price of Ferrous Sulphate is often linked to the sulfuric acid market and steel industry by-products. To secure stable pricing, consider long-term contracts (6-12 months) rather than spot buying. On Made-in-China.com, you can vet Audited Suppliers to ensure they have the production capacity to fulfill large orders during peak seasons. Always factor in ocean freight fluctuations, as chemicals are heavy and low-value, making logistics a significant portion of the Total Cost of Ownership (TCO).

Always use secure payment terms such as Letter of Credit (L/C) or Escrow services provided by reputable platforms to protect your funds until shipping documents are verified. Conduct third-party pre-shipment inspections (e.g., SGS or Intertek) to verify the quantity and chemical composition before the balance payment is made. This prevents the risk of receiving substandard or oxidized material that does not meet your technical requirements.

Ferrous Sulphate Heptahydrate is generally classified as non-hazardous for transport under IMDG codes, but you must confirm this with the specific HS Code (typically 283321). Ensure the Commercial Invoice and Packing List precisely match the chemical name and grade. For shipping to specific regions, clarify the Incoterms (FOB vs CIF); given the weight of chemical minerals, CIF (Cost, Insurance, and Freight) is often preferred for buyers who want the supplier to handle the complexities of maritime logistics.
