China Caustic Soda Weekly Report: Prices Decline Amid Rising Inventory
April 23, 2026 at 12:00:00 AM

The Chinese caustic soda market showed a clear downward trend this week, as weak downstream demand and rising inventories continued to put pressure on prices. Market sentiment remains cautious ahead of the upcoming holiday period.
๐ Prices Decline Across Key Regions
In Shandong, the benchmark 32% membrane caustic soda price averaged RMB 675/ton, down 6.51% week-on-week. Meanwhile, 50% liquid caustic soda prices dropped more sharply, falling nearly 10%.
Other key observations:
* Low-concentration caustic soda faced sluggish spot demand * Some producers reduced prices to accelerate shipments * High-concentration caustic soda export orders fell short of expectations
Overall, the market experienced broad-based price pressure, especially in northern China.
๐ฆ Supply Adjusts Slightly, Inventory Continues to Rise
Operating rates at major chlor-alkali plants declined slightly:
* Average operating rate: 83.2% (-1.1%) * Weekly output: 83.7 million tons (-2.2%)
Despite reduced output, inventory levels increased significantly:
* Total inventory: 585,500 tons * Week-on-week: +4.71% * Year-on-year: +39.02%
This indicates that demand weakness remains the key issue in the current market.
๐ญ Downstream Demand Remains Weak
Key downstream sectors showed mixed performance:
* Alumina: Demand softened, with buyers maintaining strong price pressure * Viscose fiber: Operating rates improved slightly, but demand recovery remains limited * Other sectors: Mainly purchasing based on immediate needs
Overall, downstream industries continue to adopt a cautious and wait-and-see approach.
๐ฐ Profitability Declines
Falling caustic soda prices combined with weaker chlorine prices significantly reduced profitability:
* Average chlor-alkali profit: RMB 453/ton * Week-on-week change: -26.5%
Although raw material and energy costs declined, they were insufficient to offset the price drop.
๐ฎ Market Outlook
In the short term, the caustic soda market is expected to remain under pressure:
* Prices may continue to fluctuate downward * Producers will prioritize inventory reduction * Holiday logistics may impact shipments
However, supply-side adjustments may help stabilize the market later.
