China's Potassium Chloride Market Rebounds as Tight Supply Lifts Prices

China's potassium chloride market reversed earlier bearish sentiment this week following the signing of major contracts, with prices returning to elevated ranges. As of 9 December, market data show the benchmark import price at RMB 3,533.33 per tonne, up 0.95% from RMB 3,500 per tonne at the start of the month.

Supply Fundamentals Strengthen Market Support

Port inventories remain at historically low levels for this period of the year, while China's domestic potash industry has entered its traditional winter maintenance cycle, tightening spot market availability.

Seasonal demand expectations are also beginning to materialise, particularly in Northeast China, where market activity is picking up and procurement demand is gradually being released. Against this backdrop, sentiment has shifted from bearish to steady, with notable price increases across northern regions. Laos powdered and granular potash — supported by cost advantages and proximity — have led the gains, contributing significantly to the market's recovery.

Supply-Side Developments

• China Potash

Operating rates remain low at around 45.3% this week, with weekly output at approximately 85,500 tonnes — down roughly 10% from the previous week. Factory inventories have dropped sharply to 291,500 tonnes, a 56.1% year-on-year decline. Most production continues to flow directly to downstream compound fertiliser plants, leaving limited volumes available in the broader spot market.

• Imported Potash

Port inventories recovered modestly to around 2.47 million tonnes as of 4 December, up 60,000 tonnes week-on-week. However, inventories remain 430,000 tonnes lower than the same period last year. The incremental stock build has not yet translated into meaningful market supply, and spot availability remains tight across most regions.

Overall supply is gradually improving, but reduced domestic operating rates, low inventory levels, and shipping constraints mean that effective spot supply is still insufficient in the short term — providing firm support to current pricing.

Demand-Side Trends

Downstream compound fertiliser producers have seen a clear rebound in operating rates, rising to about 38.5% this week — an increase of roughly 5.1 percentage points week-on-week. In northern regions, terminal stockpiling has accelerated, driving higher raw material enquiries and procurement activity.

Despite stronger demand fundamentals, current prices are at relatively high levels. As a result, downstream manufacturers and traders are adopting more rational purchasing strategies, largely focusing on replenishing inventories as needed and buying during price dips. Acceptance of further price increases remains limited, creating some pushback.

Outlook

China's potash market displayed solid performance this week, supported by low inventories and seasonal demand recovery. In the longer term, diversification of import sources continues to enhance overall supply chain resilience. In the near term, the tight supply-demand balance remains the primary market driver, with prices expected to fluctuate amid the interaction of strong supply-side fundamentals and cautious downstream sentiment at elevated price levels.
