China Monopotassium Phosphate Market Update: Price Trends, Supply and Raw Material Costs in August 2026
During the 33rd week of 2026 (August 10–16), the China monopotassium phosphate market remained at a relatively low price level, while market conditions gradually stabilized after a period of price declines. Upstream raw material costs remained firm, and manufacturers continued to operate at reduced production loads, limiting the room for further price reductions.
For buyers monitoring the monopotassium phosphate fertilizer market, recent developments indicate that supply, production costs and downstream demand will remain the key factors influencing the monopotassium phosphate price in the coming weeks.
monopotassium phosphate Price and Supply Trends
The current monopotassium phosphate price is relatively low compared with earlier levels, while production costs remain under pressure from key raw materials. Manufacturers have shown limited willingness to reduce prices further as margins have already become relatively narrow.
On the demand side, downstream buyers have gradually reduced their wait-and-see approach. Some essential purchasing has started to return to the market, resulting in slightly improved trading activity compared with previous weeks.
Supply has also tightened as some producers have reduced operating rates. This combination of controlled production and recovering demand is providing additional support to the China monopotassium phosphate market.
Raw Material Costs Remain Firm
The cost structure of Monopotassium Phosphate continues to be influenced by upstream phosphorus and potassium raw materials.
Yellow phosphorus prices were around RMB 26,800–27,300 per metric ton during the week. Prices moved slightly higher as some production units were affected by shutdowns and safety inspections. Although the wet season provides relatively favorable power costs in major producing areas, supply conditions and producer sentiment continue to support prices.
Thermal-process phosphoric acid remained around RMB 8,500–8,600 per metric ton. High yellow phosphorus costs continue to provide cost support, while relatively moderate downstream demand limits upward movement.
Wet-process phosphoric acid was around RMB 9,200–9,500 per metric ton, supported by renewed purchasing from the new-energy sector. Its price remained above thermal-process phosphoric acid during the week.
On the potassium side, potassium chloride averaged approximately RMB 3,221/MT, with high port inventories putting some pressure on prices. Meanwhile, 48% liquid potassium hydroxide remained relatively stable at around RMB 3,242/MT, supported by firm production costs.

Outlook for the China monopotassium phosphate Market
In the short term, the monopotassium phosphate fertilizer market is expected to remain relatively stable, with limited downside room as upstream costs remain firm and production loads are controlled.
Looking ahead, the gradual release of autumn fertilizer demand could provide additional support to the Monopotassium Phosphate market. If major raw material prices remain firm, the monopotassium phosphate price is likely to show greater resilience rather than experience another significant decline.
For international buyers, the current market is worth monitoring closely. Price movements will depend on the balance between raw material costs, production levels and seasonal demand in the coming weeks.
Sichuan Luobu will continue to monitor the China monopotassium phosphate market, raw material prices and supply conditions, providing regular market updates for global buyers of monopotassium phosphate fertilizer.
