Edta fe manufacturers

When procuring EDTA Fe, the most critical factor is the Iron (Fe) content, which typically ranges from 12.5% to 13.3% for the sodium salt form. You must verify the chelation percentage; high-quality products should have a chelation rate of ≥99% to ensure stability. Additionally, check the pH value (1% water solution), which should ideally be between 3.5 and 5.5, and ensure water solubility is ≥99.5% to prevent clogging in fertigation systems.

For agricultural use, prioritize EDTA Fe 13% micro-granular or powder forms, as they offer better bioavailability in soils with a pH below 7. If you are using it in the photo-sensitive or textile industry, you must request a heavy metal analysis report, ensuring Lead (Pb) and Arsenic (As) levels are within strict ppm limits to avoid contamination of the final industrial process.

Ensure the supplier provides a Certificate of Analysis (COA) for every batch. For international trade, the product should comply with REACH regulations (for EU markets) and have a valid MSDS (Material Safety Data Sheet). If intended for high-end agriculture, look for ISO 9001:2015 quality management certification and check if the product meets FAO/WHO specifications for micro-nutrients.

Request a sample to test for caking resistance and dissolution speed. High-quality EDTA Fe should be a free-flowing yellow or light brown powder/granule that dissolves completely in water without leaving residue. Perform a stability test by exposing a small amount to light and air; premium chelated iron should remain stable and not undergo rapid photodegradation or oxidation.

The primary risk is product degradation or moisture absorption during sea freight. To mitigate this, insist on moisture-proof packaging, such as 25kg PE-lined Kraft paper bags or big bags with UV protection. Always use Made-in-China.com's Secured Trading services to ensure that payment is only released after the third-party inspection (like SGS or Intertek) confirms the chemical purity matches the contract.

EDTA Fe pricing is sensitive to the cost of raw materials like EDTA acid and iron salts. Negotiate based on volume tiers; typically, orders exceeding 5-10 metric tons can secure a 5-8% discount. For long-term cooperation, request a formula-based pricing model linked to market indices. If you are a first-time buyer, look for suppliers on Made-in-China.com who offer flexible MOQs (e.g., 1 ton) for market testing.

EDTA Fe is generally classified as non-hazardous for transport, but you must ensure the HS Code (typically 292249) is correctly declared to avoid customs delays. When shipping to regions with high humidity, specify container desiccant usage. For inland delivery, confirm if the supplier can provide palletized loading to facilitate easy unloading with forklifts at your warehouse.

Focus on Audited Suppliers on Made-in-China.com, as these companies have undergone on-site verification of their production capacity and R&D facilities. Check their export history to your specific region and ask for traceability documentation for their raw material sourcing to ensure consistent quality across different production lots.
