Buyer Reviews
"Ordered two 20ft containers of MKP 99% for our rice and durian foliar programs. The crystal dissolves completely with zero residue, so no clogged nozzles even after a full season. The pre-shipment lab report matched the COA exactly."
"We use their pure-powder MKP for UAV spraying on ginseng and apple orchards. The 0-52-34 grade is exactly as spec'd, and their export team handled all customs documents flawlessly in English."
"Bought MKP for our drip-fertigation blending business. Consistent 99% purity across three consecutive shipments, and payment terms were flexible (L/C at sight). This is the supplier I recommend to fellow traders in India."
"We import water-soluble fertilizer for greenhouse tomatoes in Almería. Ansheng's MKP passed our EU residue and heavy-metal checks on first submission, and their REACH documentation was prompt and complete."
"Large-volume buyer for coffee and citrus fertigation. Being 30 km from Guoyuan Port means fast container turnaround and lower inland freight. Quality has been rock solid across 12 containers."
"They understood Middle East requirements from day one: proper moisture-barrier packaging and complete documentation. Our distributor network now requests Ansheng MKP by name."
"We did a factory audit before committing. The patented organic-solvent process with purified phosphoric acid is genuine and well-run, and their QC lab issues a COA with every batch. Very professional."
"Reordering for the third time. The 25-ton MOQ fits our container schedule perfectly. I only wish the lead time could be shorter in peak season, but the quality fully justifies the wait."

Buyer FAQ
Industrial-grade 99% monopotassium phosphate (MKP) typically trades at $800–$1,200 per metric ton FOB China, depending on purity, form (crystal vs pure powder), and order volume. Chongqing Ansheng Chemical's 99% MKP (0-52-34) sits in this range, with full water solubility and a UAV-spraying grade available for agricultural buyers.
Tech Deep-Dive
MKP's 0-52-34 NPK ratio delivers 52% phosphorus (P₂O₅) and 34% potassium (K₂O) with zero nitrogen and zero chlorine, making it the cleanest potassium-phosphorus source for fertigation. Its 100% water solubility prevents nozzle clogging in drip systems and makes it ideal for UAV spraying, which is why it is the standard for high-value greenhouse and orchard crops.
Case Study
A greenhouse tomato grower in Almería, Spain switched from standard NPK to Ansheng 99% MKP in drip fertigation. Result: improved fruit firmness and color, zero nozzle clogging across two seasons, and a cleaner nutrient profile that passed EU residue checks. This mirrors what European greenhouse operators search for when vetting China MKP suppliers.
Industry Knowledge
(1) Purity (must be ≥99% for export grade), (2) NPK ratio (verify 0-52-34), (3) water solubility (100% soluble, no residue), (4) form (crystal vs pure powder for UAV), (5) production process (patented organic-solvent vs thermal), (6) packaging (25kg bags vs big bags), (7) compliance (ISO/REACH). Checking these seven is how experienced fertilizer buyers filter out substandard suppliers.
Company Update
Chongqing Ansheng Chemical expanded its MKP exports to Southeast Asia and Latin America this quarter, adding new distributors in Thailand, Vietnam, and Colombia. Located only 30 km from Guoyuan Port, the company now ships river-sea and rail-sea containers to 20+ countries, backed by its national high-tech enterprise qualification.
Buyer FAQ
For bulk MKP orders the standard MOQ is 25 metric tons (one 20ft container). Packaging is 25 kg moisture-barrier bags or 1,000 kg big bags, and 1–5 kg samples are available for evaluation. Payment terms are T/T or L/C at sight, the standard terms buyers should expect from a verified Chinese chemical manufacturer.
