Zinc EDTA

Description

1. Product Overview

Zinc EDTA is a high-purity, chelated zinc micronutrient engineered for maximum solubility and immediate bioavailability across industrial and agricultural applications. Its primary industrial use is correcting and preventing zinc deficiency in high-value crop production, hydroponic nutrient solutions, and precision fertigation systems. The key value proposition lies in its superior stability across a wide pH range (2–11), ensuring that zinc remains plant-available where conventional sulfates or oxides precipitate and become inert. In a global market increasingly driven by yield optimization and input efficiency, Zinc EDTA is strategically critical for agri-businesses seeking to reduce waste, enhance nutrient use efficiency (NUE), and secure predictable crop outcomes.

2. Key Specifications & Technical Characteristics

• Chemical composition: Zinc Ethylenediaminetetraacetate (Na₂Zn EDTA), typically 14–15% Zn by weight (chelated fraction: 100%)

• Purity level: Min. 99% (chelated zinc content), free of heavy metals (Pb, Cd, As, Hg below regulatory limits)

• Physical characteristics:

  • Form: Fine, free-flowing microgranular or crystalline powder

  • Color: White to off-white

  • Particle size: 100% passing through 100 mesh (≤150 µm)

  • Bulk density: approx. 0.65–0.75 g/cm³

  • pH (1% solution): 6.0–7.5

  • Water solubility: Complete (no turbidity)

• Packaging options: 25 kg multi-layered kraft + PE bags; 500 kg and 1000 kg woven FIBCs (big bags)

• Shelf life: 36 months in original unopened packaging, stored in dry, ambient conditions (no caking risk)

3. Core Industrial Applications

• Primary industries: Precision agriculture, greenhouse horticulture, hydroponics, turf management, and specialty fertilizer manufacturing

• Specific operational use cases:

  • Correction of zinc deficiency in corn, rice, wheat, citrus, and apples (leaf chlorosis, stunted growth)

  • Base component in water-soluble NPK blends and liquid starter fertilizers

  • Continuous dosing in recirculating hydroponic systems (tomato, pepper, leafy greens)

• Why this product performs better than alternatives:

  • Unlike zinc sulfate, Zinc EDTA does not react with phosphates or carbonates in alkaline soils (pH >7.0), maintaining 100% plant uptake efficiency

  • Zero phytotoxicity risk at recommended rates due to controlled release via chelation

  • Enables tank-mixing with most agrochemicals (fungicides, insecticides, PGRs) without precipitation, reducing application passes and labor costs

• Efficiency advantage: Achieves target zinc correction with 5–10× lower application rates compared to inorganic salts, directly lowering freight and field operations cost per hectare

4. Competitive Advantages

• Quality consistency: ISO 9001:2025-certified production with batch-by-batch HPLC-ICP analysis; certificate of analysis (CoA) provided for every shipment

• Supply reliability: Dual-sourced raw material buffer stock and three manufacturing nodes (Asia, EMEA, Americas) ensuring ≤10-day lead time for contract customers

• Logistics capability: In-house hazardous reclassification documentation (non-hazardous under GHS for transport) – ships as general cargo, reducing freight complexity and insurance costs

• Price competitiveness: Vertically integrated production from EDTA to final chelation, removing 2–3 intermediary margins vs. traders

• Sustainability benefit: Biodegradable chelating agent (EDTA degrades >80% within 28 days per OECD 301); zero heavy metal leaching into groundwater

• Technical support: Full agronomic formulation guidance, stability compatibility charts, and custom blending support provided by in-house PhD-level team

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (MT) – one full industrial palletized truckload

• BULK loading capacity: 20 MT per 20’ dry container (18–20 MT net, depending on bag density and pallet configuration)

• Typical shipment configuration: 800 × 25 kg bags on 40 heat-treated euro pallets, shrink-wrapped and strapped, or 20 × 1000 kg FIBCs

• Incoterms supported: FOB, CIF, CFR (major global ports: Rotterdam, Shanghai, Houston, Santos, Durban)
