Bulk sourcing routes
Start with the product, specification and destination port
RunziChem separates manufactured chelates from the wider export-supply catalogue so buyers can reach the right technical page without searching through a generic product list. Select a route below, then send the target grade, annual volume, packaging and destination port for current documents and a quotation.
Fertilizer raw materials supplier in China
Screen MKP 0-52-34, MAP 12-61-0, SOP, potassium nitrate, ammonium sulphate, magnesium sources, borates, sulphates and selected organic inputs for blending or fertigation.
Custom micronutrient blends and private label
Review two standard compound EDTA grades or submit a target analysis for feasibility review. Packaging, MOQ, sample options, lead time and final price are confirmed for each inquiry.
What should a buyer include in an RFQ?
A useful bulk fertilizer RFQ names the product or target analysis, required assay, annual or trial volume, pack size, destination port and documents needed. RunziChem can then return the closest current specification, a sample COA where available, TDS, SDS, packaging options and a quotation. Website specifications are screening values; the current batch COA confirms the final assay.

Buyer FAQ
Common procurement questions
What does RunziChem manufacture and supply?
RunziChem manufactures EDTA and EDDHA chelated micronutrients and custom trace-element blends. The export range also includes fertilizer raw materials such as zinc sulphate, copper sulphate, borax, boric acid, MKP, MAP and SOP. Product values are typical and final assays are confirmed per batch COA.
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.
