Iron chelate eddha manufacturers

The most critical factor is the ortho-ortho isomer content, which typically ranges from 1.2% to 4.8%. Higher ortho-ortho levels ensure greater stability in high-pH alkaline soils (up to pH 9). You should also verify the total iron (Fe) content, which is standardly 6%, and ensure the product is 100% water-soluble to prevent clogging in irrigation systems.

EDDHA is specifically designed for calcareous and alkaline soils where other chelates like EDTA fail. It is ideal for high-value crops such as citrus, grapes, strawberries, and greenhouse vegetables. For hydroponic systems, ensure the product has low heavy metal impurities to avoid phytotoxicity.

Ensure the supplier provides a Certificate of Analysis (COA) for every batch. For international trade, look for ISO 9001 certification and compliance with REACH regulations if exporting to Europe. If the product is intended for organic farming, check for OMRI listing or equivalent organic input certifications.

Request a sample to test the granulation and dust levels; micro-granular forms are preferred for easier handling. Perform a solubility test: the powder should dissolve completely in water within minutes, forming a deep red/dark purple solution without leaving any visible residue or sediment.

The primary risk is specification mismatch, where the actual ortho-ortho content is lower than advertised. To mitigate this, use third-party inspection services (like SGS or Intertek) before shipment. Another risk is moisture absorption during sea transit; ensure the supplier uses moisture-proof, multi-layer PE/PP bags and palletizes the cargo with shrink wrap.

Prices for EDDHA are sensitive to raw material costs (ethylenediamine and phenol). Negotiate based on volume tiers, as orders exceeding 5-10 metric tons usually qualify for significant discounts. For first-time buyers on Made-in-China.com, start with a trial order of 1 ton to verify the logistics chain and product efficacy before scaling.

Iron Chelate EDDHA is generally classified as non-hazardous for transport, but you must obtain a Material Safety Data Sheet (MSDS) and a Certification for Safe Transport of Chemical Goods. Ensure the HS Code (usually 292249 or 310590) is correctly declared to avoid customs delays and ensure correct tariff application.

Always conduct transactions through secure payment channels and prioritize Audited Suppliers on Made-in-China.com who have undergone on-site verification. Use Escrow-based payment terms or Letter of Credit (L/C) for large bulk orders to protect your capital until the bill of lading is issued.
