Product Description 

Detail Information

Export-grade high-content Ferrous sulfate heptahydrate granules for agriculture are commonly used fertilizers for iron supplementation and acidification in agriculture. They meet strict international market requirements in terms of purity standards, packaging, transportation, and export procedures. The following is a detailed summary of their core information:

1. Core Product Specifications

·Purity and Key Indicators: The purity of mainstream export products is mostly 98%, with some high-end products reaching 90%-99%. The corresponding minimum iron content is no less than 19%, fully meeting the iron supplementation needs of crops. At the same time, export products have extremely strict impurity control; the content of harmful heavy metals such as arsenic and lead must comply with the agricultural chemical standards of the importing country to avoid soil and crop pollution. The granule size is commonly 16-20 mesh (particle diameter 0.85-1.18mm), but there are also conventional particle sizes of 2-4 mesh. The granules are uniform and dry, with a moderate dissolution rate, convenient for field application or fertigation, and have high bioavailability. Its CAS number is fixed at 7782-63-0, a core identifier in international trade.

• Quality Certification: To meet the access requirements of different global markets, these products typically undergo ISO 9001 or other quality management system certifications. Some products exported to stricter regions also come with CIQ inspection and quarantine certificates to ensure product quality complies with internationally recognized agricultural chemical standards.

2. Packaging and Transportation Specifications

• Packaging Standards: Export packaging prioritizes moisture-proof sealing. Common packaging includes standard woven bags of 25 kg/bag and 50 kg/bag, but ton bags are also available upon order request. Double-layer woven bags are frequently used, with an inner moisture-proof film to prevent oxidation, discoloration, and clumping during transportation, ensuring no loss of active ingredients. The packaging must be labeled according to international standards with the product name, purity, particle size, net weight, CAS number, manufacturer, instructions for use, and moisture warnings.

• Transportation Details: This product is primarily exported by sea, with FOB pricing being common. For example, FOB prices for orders starting at 27 tons have been as low as $60/ton. Regarding transportation time, regardless of peak or off-peak seasons, the preparation and transportation cycle for regular orders is generally within 15 working days. Although it is not classified as a high-risk or dangerous good, it should be avoided from being mixed with alkaline substances to prevent chemical reactions that could reduce fertilizer effectiveness.
