Extraction-based MKP process
We produce monopotassium phosphate with our own patented composite organic solvent and purified phosphoric acid, not by simple neutralisation of technical-grade acid.
EU REACH registered · State-level high-tech enterprise
Specialist manufacturer of MKP and water-soluble phosphate fertilizers
Chongqing Ansheng Potassium Industry Co., Ltd. produces industrial-grade 99% monopotassium phosphate (0-52-34) and phosphate-based water-soluble fertilizers using our own extraction route, with purified phosphoric acid (purity > 85%) and 62% crystalline potassium chloride.
20,000 m² Production site in Changshou, Chongqing
30 km From Chongqing Guoyuan Port
99.8% KH₂PO₄ assay, SGS tested
Product portfolio
A focused range built on our own purified phosphoric acid — one integrated production route from raw material to finished fertilizer.
MKP 0-52-34 Industrial grade 99%
Monopotassium Phosphate 0-52-34 (Crystal)
A high-concentration, fully water-soluble phosphorus and potassium fertilizer with an assay of 99% (0-52-34), produced by our extraction route with purified phosphoric acid and 62% crystalline potassium chloride. Crystal grade for blending, fertigation and foliar application.

Why buyers work with us 
Our advantage is the production route itself, not a trading margin.
Higher-purity raw material
62% crystalline potassium chloride is used as the potassium source, which keeps impurity levels low and makes the product more suitable for end users.
One-stop production at the source
Purified phosphoric acid, crystal, powder and water-soluble blends are produced on one integrated site for better resource efficiency and traceability.
By-product recovery
Ammonium chloride is recovered as a by-product, so the production process meets environmental requirements instead of discharging waste streams.
Quality control and certification
Products are produced to a documented standard and can be shipped with third-party inspection.
Industrial-grade export standard
Industrial-grade 99% MKP in crystal and pure powder (UAV-specific) specifications, meeting the industrial export first-grade standard of HG/T 2321.
SGS testing report
Typical SGS results: KH₂PO₄ 99.8%, P₂O₅ 52.0%, K₂O 34.21%, moisture 0.1%, water-insoluble 0.01%, pH 4.5, trace heavy metals below reporting limits.
EU REACH registered
Full REACH registration for EC 231-913-4 / CAS 7778-77-0 through a registered only-representative, tonnage band 100–1,000 tonnes per year.
Recognised enterprise status
State-level high-tech enterprise, Chongqing specialised, sophisticated, unique and innovative (SME) enterprise, and a fine-phosphate demonstration project.
Certificates and test reports are issued to Chongqing Ansheng Potassium Industry Co., Ltd. Specifications and certification scope are confirmed per order — please request the current documents before contracting.
Export markets
Products are already exported to the following regions:
In China we supply large state-owned agricultural material groups, including China Agricultural Materials, Chongqing Agricultural Materials, Shanghai Agricultural Materials and Xinjiang Agricultural Materials.
The plant is located in the Changshou chemical industrial development zone, Chongqing — a 20,000 m² site only 30 km from Chongqing Guoyuan Port, which makes river-sea and rail-sea container transport convenient.
