Water-Soluble Phosphate Fertilizers

Ammonium Polyphosphate (APP)

Ammonium polyphosphate 10-34-0 — a liquid phosphate fertilizer used in fertigation and as a base for liquid NPK blends. Described here for reference; supply is not offered at present.

10-34-0 (NH4)n+2PnO3n+1 Clear to slightly cloudy liquid

Industry information — not currently offered

Ammonium polyphosphate is the phosphate that moves as a liquid. The standard grade, 10-34-0, is a solution of ammonium phosphate polymers that carries 10% nitrogen and 34% P2O5 in a form that can be pumped, blended and injected.

Its commercial role is in liquid fertilizer systems: bulk liquid NPK blends, starter fertilizers applied at planting, and fertigation where a liquid phosphate is easier to handle than a bagged solid. It also sequesters metal ions, which is why it appears in some micronutrient formulations.

This page exists because buyers ask about it. We do not currently offer ammonium polyphosphate, and the page is written to explain the product rather than to sell it. Where a liquid phosphate is required, the practical alternatives are water-soluble MAP or urea phosphate in solid form.

Specification

The table below gives the nominal analysis and the parameters that a buyer should write into the contract. Values that depend on the production lot are not printed as numbers here, because a number on a website is not a guarantee — the lot COA is.

APP 10-34-0 — typical specification
Parameter Value
Total nitrogen (N) 10% typical
P2O5 34% typical
Specific gravity Confirmed per lot — see TDS / COA
pH Confirmed per lot — see TDS / COA
Crystallisation temperature Confirmed per lot — see TDS / COA The storage parameter that matters in cold climates

Typical values describe the grade as it is normally traded. The guaranteed analysis for your order is the one stated on the certificate of analysis issued for the production lot, and it is confirmed in the sales contract before shipment.

Reference only: This product is described so buyers can understand the grade and where it sits in the phosphate chain. We do not currently offer it, and no quotation entry point is provided on this page.

Applications

  • Liquid NPK blend manufacture
  • Starter fertilizer applied at planting
  • Fertigation through liquid injection systems
  • Micronutrient suspension formulations

Why this product, and not the one next to it

Pumpable

A liquid phosphate removes bag handling and dust from the blending plant and can be metered into a blend by volume.

Fully soluble by definition

There is no insoluble residue to settle out, which is the property that makes it suitable for injection systems.

Sequesters micronutrients

The polyphosphate chain holds metal ions in solution, which is why it is used in liquid micronutrient products.

Packaging options

  • Bulk tanker or ISO tank, for industrial volumes
  • IBC totes
  • Drums, for smaller quantities

Loading quantity depends on packaging, container type and the weight limit of the destination country. It is confirmed per order. The bag type, bag weight, liner and marks are stated on the quotation so that two offers can be compared on the same basis.

Quality documentation

  • Certificate of analysis for the production lot
  • Technical data sheet
  • Material safety data sheet

Documents are issued on a per-shipment basis. Certification availability is confirmed for each order before contract.

Export considerations

Ammonium polyphosphate is a liquid and is shipped in ISO tanks, IBCs or drums rather than in bags. That changes the freight calculation completely compared with a solid phosphate.

Crystallisation temperature governs where the product can be stored: a grade formulated for a cold climate is not the same as one formulated for a warm one, and the figure has to be agreed in the contract.

This product is described for reference. We do not currently offer it, and no quotation entry point is provided on this page.

Export regulations and import requirements can change. This is a general overview written for buyers, not a substitute for confirming current requirements with your customs broker and with our export team before you commit to a shipment.

Questions buyers ask about APP

Do you supply ammonium polyphosphate?

No, not at present. The page is here because buyers ask about it and because it is the liquid counterpart of the solid phosphates we do handle. For a liquid requirement, talk to us about water-soluble MAP or urea phosphate, which deliver phosphate in a solid that is dissolved on site.

Why is APP always quoted as a liquid?

The commercial grade is manufactured and sold as a solution. A solid ammonium polyphosphate exists, but the product traded in fertilizer markets at 10-34-0 is a liquid.
