Fertilizer Raw Materials

29 fertilizer raw materials across four nutrient groups — macro (N·P·K), secondary (Mg·Si·Ca), micro (Fe·B·Zn·Mn·Cu·Mo) and organic. Sulphates, nitrates, phosphates, EDTA/EDDHA chelates and biostimulants for blending and formulation.

What this category covers

One source for macro, secondary, micro and organic inputs

Fertilizer Raw Materials from RunziChem span 29 products in four nutrient groups: 5 macro-nutrients (N·P·K sources), 6 secondary nutrients (Mg·Si·Ca), 14 micro-nutrients (Fe·B·Zn·Mn·Cu·Mo in sulphate and EDTA/EDDHA forms), and 4 organic materials. Each ships with TDS, COA and SDS in 25/50 kg and 1,250 kg packaging.

  • What it is Straight raw materials — sulphates, nitrates, phosphates, borates, EDTA/EDDHA chelates and biostimulants — for blending, compound-fertilizer lines and single-nutrient dosing.
  • When to use Use raw materials when you formulate your own blends; choose finished Water-Soluble Fertilizers when you want a ready-to-use foliar or fertigation product.
  • Honesty note Percentages shown are typical or industry-typical values for evaluation; final assays are confirmed per batch COA.

Buyer FAQ

Fertilizer raw material questions

How do I choose between a sulphate raw material and an EDTA chelate?
Sulphates such as zinc sulphate (Zn 33-35%) or manganese sulphate (Mn 31-32%) are economical raw materials for soil application and dry blending. EDTA chelates such as EDTA-Zn-15 (Zn 15%) or EDTA-Fe-13 (Fe 13%) stay soluble and stable across a wider pH range, so they suit foliar, drip, and hydroponic programs. RunziChem supplies both across the micro-nutrient group.
Should I buy single raw materials or a finished water-soluble fertilizer?
Buy raw materials when you blend your own formulas, feed a compound-fertilizer line, or dose a single nutrient. Choose RunziChem's finished Water-Soluble Fertilizers — 8 NPK+TE grades and inorganic or EDTA micronutrient blends — when you want a ready-to-use foliar or fertigation product. Many buyers combine both: raw materials as bases plus finished fertilizers for convenience.
What is the minimum order quantity and packaging for RunziChem raw materials?
RunziChem raw materials ship in 25 kg / 50 kg export bags, jumbo bags (1,250 kg), and custom packaging on request. Minimum order quantity depends on the specific product, grade, and destination — a full container load is typical for commodity sulphates, while chelates and speciality organics can move in smaller lots. Confirm MOQ and packaging per inquiry.
What documents come with each raw material and are the assays guaranteed?
Every RunziChem raw material is supplied with a technical data sheet (TDS), the current batch certificate of analysis (COA), and a safety data sheet (SDS) on request. The percentages shown on this page are typical or industry-typical values for buyer screening; the final assay, moisture, and appearance are confirmed by the batch COA for the lot you receive.

Send the products, grades, annual volume, destination market, and packaging you need. RunziChem can provide TDS, current batch COA, SDS, and a formal quotation across all four nutrient groups.
