Eddha iron chelate manufacturers

The most critical factor is the ortho-ortho isomer content, which determines the stability and effectiveness of the product in high-pH soils. High-quality EDDHA Fe typically ranges from 1.2% to 4.8% ortho-ortho. You should also verify the total iron content (usually 6%), solubility (100% water-soluble), and the pH stability range (typically pH 4.0 to 9.0) to ensure it performs in alkaline conditions.

Request a Certificate of Analysis (COA) for every batch. Professional buyers should look for HPLC (High-Performance Liquid Chromatography) test reports to confirm the isomer distribution. Additionally, check for heavy metal limits (such as Lead, Arsenic, and Cadmium) to ensure compliance with agricultural safety standards and environmental regulations.

EDDHA Iron is primarily used to treat and prevent iron chlorosis (yellow leaf disease) in high-value crops like citrus, grapes, strawberries, and greenhouse vegetables. Its main function is to remain bioavailable in calcareous soils where standard EDTA iron would precipitate and become useless. It is suitable for fertigation, hydroponics, and soil injection.

Since EDDHA Fe is sensitive to light and moisture, it should be packed in UV-protected, moisture-proof bags (typically 1kg, 5kg, or 25kg PP/PE bags). For B2B sourcing, ensure the supplier uses palletized shipping with shrink wrap to prevent bag breakage during sea freight. Store in a cool, dry, and ventilated warehouse away from direct sunlight.

The primary risk is adulteration or 'fake' ortho-content, where suppliers mix lower-grade EDTA or inferior isomers. To mitigate this, use third-party inspection services like SGS or Intertek before shipment. Another risk is regulatory non-compliance; ensure the product is registered or meets the fertilizer import standards of your specific country to avoid customs seizure.

Focus on volume-based pricing tiers; for example, ordering in full container loads (FCL) can reduce unit costs by 10-15% compared to LCL. Request FOB (Free On Board) terms if you have a reliable freight forwarder to control logistics costs. For new suppliers on Made-in-China.com, start with a paid sample (500g-1kg) to test solubility and color intensity before committing to a large contract.

Always conduct transactions through secured payment channels provided by reputable platforms like Made-in-China.com to ensure escrow protection. Avoid direct wire transfers to private accounts. Ensure the Proforma Invoice (PI) clearly states the ortho-ortho percentage and packaging specifications to provide legal recourse in case of quality disputes.

EDDHA Iron Chelate is generally classified as non-hazardous for transport, but you must obtain a Material Safety Data Sheet (MSDS) and a Non-Hazardous Chemical Declaration from the supplier. For customs clearance, ensure you have the Commercial Invoice, Packing List, Bill of Lading, and Phytosanitary Certificate (if required by your local ministry of agriculture).
