Micronutrient Chemistry for Higher-Yield Agriculture

Q: What is an EDTA-chelated micronutrient?

An EDTA-chelated micronutrient is a metal nutrient such as zinc, iron, manganese, or copper bound to EDTA, an organic chelating agent. The chelate keeps the metal soluble and plant-available across a range of soil and water conditions, which suits foliar sprays, drip irrigation, and water-soluble fertilizers.

Q: Does RunziChem support private label and custom blending?

Yes. RunziChem supports custom trace-element formulations, custom mesh and assay specifications, and private-label packaging for distributors and fertilizer brands, subject to confirmation by the sales team.

EDTA-chelated micronutrients, soluble 200–500 mesh powders, sulfate and borate raw materials, and custom trace-element blends — engineered for fertilizer manufacturers, distributors, and crop-nutrition brands worldwide.

Buyer FAQ

Common procurement questions

What does RunziChem manufacture?

RunziChem (Shandong Jinrunzi Biotechnology) manufactures agricultural micronutrient fertilizers and trace-element raw materials: EDTA-chelated micronutrients (Fe, Zn, Mn, Cu, Mg, Ca), soluble 200–500 mesh powders, sulfate raw materials such as zinc and copper sulfate, borate raw materials such as boric acid and borax, and custom trace-element blends.

What is an EDTA-chelated micronutrient?

It is a metal nutrient — zinc, iron, manganese, or copper — bound to EDTA, an organic chelating agent. The chelate keeps the metal soluble and plant-available across a range of soil and water conditions, making it well suited to foliar sprays, drip irrigation, and water-soluble fertilizers.

Do you support private label and custom blending?

Yes. We support custom trace-element formulations, custom mesh and assay specifications, and private-label packaging for distributors and fertilizer brands, subject to confirmation by the sales team.

Which regions do you export to?

We export to buyers in Southeast Asia, the Middle East, Africa, and Eastern Europe, and hold independent import/export rights. Packaging is available in 25 kg, 50 kg, and jumbo bags.

Can I get a COA, TDS, and SDS before ordering?

Yes. A technical data sheet (TDS), a sample certificate of analysis (COA), and a safety data sheet (SDS) are available on request for each grade so you can evaluate the product before placing an order.
