Edta fe 13%

Buyers must ensure the Iron (Fe) content is strictly ≥13.0%. The product should appear as a yellow or light brown micro-granular or powder with high water solubility (typically ≥90g/L at 20°C). Check the pH value of a 1% aqueous solution, which should ideally fall between 3.5 and 5.5 for optimal stability. Additionally, verify the heavy metal limits (Lead, Arsenic, Cadmium) to ensure they meet agricultural safety standards.

It is primarily used as a trace element fertilizer in agriculture and horticulture to prevent and correct iron deficiency (chlorosis). It is highly effective in foliar spraying, fertigation, and hydroponic systems. Due to its stable chelated state, it is suitable for use in acidic or slightly alkaline soils, though for highly alkaline soils (pH >8), EDDHA Fe might be a more stable alternative.

Suppliers should provide a Certificate of Analysis (COA) for every batch. For entry into the EU, REACH registration is mandatory. If the product is intended for organic farming, check for OMRI or ECOCERT certification. Furthermore, ensure the supplier complies with ISO 9001 for quality management and ISO 14001 for environmental standards.

Request a solubility test report to ensure there is no residue, which is critical for preventing nozzle clogging in irrigation systems. The chelation rate should be ≥99%; a high chelation rate ensures that the iron ions are protected from reacting with other minerals in the soil, maintaining high bioavailability for plants.

The primary risk is purity degradation or adulteration with cheaper inorganic iron salts. Another risk is moisture absorption during sea transit if the packaging is not airtight. To mitigate this, insist on double-layered packaging (PE inner bag + PP woven outer bag) and consider third-party pre-shipment inspections (like SGS) to verify weight and quality.

Focus on Tiered Pricing based on volume; for orders exceeding 20 tons (a full 20ft container), you should aim for a 10-15% discount compared to LCL prices. Discuss OEM packaging options if you are a distributor. Always clarify the Lead Time, which typically ranges from 7 to 15 days for standard specifications.

EDTA Fe 13% is generally classified as non-hazardous for transport, but you must confirm this with the supplier's MSDS (Material Safety Data Sheet). Ensure the cargo is stored in a cool, dry, and ventilated warehouse away from strong oxidizers. For shipping to regions with high humidity, use desiccants inside the container to prevent caking.

Utilize Secured Trading Services offered by platforms like Made-in-China.com to protect your payment until delivery is confirmed. For large-scale contracts, use Letter of Credit (L/C) or Telegraphic Transfer (T/T) with a 30% deposit and the remaining 70% against the Bill of Lading (B/L) copy.
