Price Comparison: EDTA-Fe 13% vs EDDHA-Fe 6% (2026 Global Bulk FOB Prices, China Origin)

All prices are agricultural water-soluble powder grade, based on MOQ ≥5MT factory bulk export; retail small-pack prices are much higher.

1. EDTA-Fe 13% (Ferric Sodium EDTA)

Standard quality: USD 2,500 – 3,500 / MT (USD 2.5–3.5 per kg)

USD 2.2 – 4.05 / kg

Higher iron concentration (13% chelated Fe) → lower dosage per unit of iron needed for foliar spraying.

EDDHA production cost is far higher due to complex synthesis, raw material costs, and purification steps.

Regular O-O 2.0–3.0: USD 2,600 – 3,500 / MT (USD 2.6–3.5 per kg)

High O-O ≥4.5 premium grade: USD 3,600 – 5,500 / MT (USD 3.1–4.8/kg)

USD 3.5 – 6.5 / kg

Ortho-Ortho (O-O) content for EDDHA Higher O-O = better alkaline stability, higher price. 4.8% O-O grade costs 30%+ extra vs 2% O-O.

Order volume: Full container (20MT+) gets the lowest FOB price; <1MT small orders carry surcharges.

Heavy metal standard: EU/Organic certified grades add 15–30% cost.

Seasonal raw material fluctuation (EDTA & EDDHA chemical feedstock prices shift monthly).

Use EDTA-Fe whenever possible (pH <6.5 soil / foliar spray) to cut iron input cost by ~70%.

Only use EDDHA-Fe for root application in alkaline/calcareous soil (pH >6.5), where EDTA-Fe loses all activity and becomes a total waste of money.
