4. Supply-Demand Dynamics
- Supply Side:
- As of March 2026, China’s total soda ash production capacity exceeded 47.5 million tons annually, with daily output reaching 130,000 tons. Even considering monthly maintenance-related losses of 700,000 tons, the overall impact on supply remains limited. Producers have shifted from centralized annual maintenance to year-round distributed rotational maintenance. In March 2026, the maximum daily output reduction due to maintenance reached ~15,000 tons—only 11.5% of the national average daily output. As of April 2, 2026, enterprise inventories stood at 1.8861 million tons—up 21,300 tons from the previous trading day—and have remained above 1.4 million tons for 18 consecutive months, occupying the top 5% percentile (i.e., historically extreme high) of inventory levels.
- On May 27, 2025, as some enterprises resumed operations following maintenance, industry operating rates edged upward slightly, resulting in modest supply growth.
- Demand Side:
- Light soda ash demand in 2026 remains stable and moderately positive; however, downstream enterprises demonstrate low willingness to stockpile, leading to subdued market trading activity and increased procurement at lower prices. Heavy soda ash demand has declined, as daily melt capacity in flat glass and photovoltaic (PV) glass sectors contracts, weakening heavy soda ash demand fundamentals. This indirectly suppresses light soda ash pricing. Nevertheless, emerging sectors—including PV glass and lithium carbonate production—are driving an increase in demand for premium-grade light soda ash (purity ≥99.2%, Fe content ≤30 ppm), which now accounts for 48% of total light soda ash consumption. Yet this trend is insufficient to reverse the overall supply-demand imbalance in the near term.
- On May 27, 2025, terminal market transactions were limited; downstream buyers purchased strictly on a just-in-time basis. In certain regions, flat glass prices declined, further weakening support for soda ash.

II. Analysis and Assessment
1. Reasons for Weak Pricing
- Persistent oversupply pressure, coupled with historically elevated enterprise inventories, ensures abundant market availability—even scheduled maintenance exerts minimal constraint on supply.
- Demand-side weakness persists: downstream enterprises show low purchasing enthusiasm, new order inflows are sluggish, and buying behavior remains predominantly need-driven—resulting in subpar transaction volumes and a lack of upward price catalysts.

2. Causes of Regional Price Differentials
- Regional supply-demand imbalances vary. The North China region’s prices are approximately 5–10% higher than those in Central and East China—potentially attributable to relatively tighter local supply or higher logistics costs.

3. Causes of Enterprise Quotation Divergence
- Quotation disparities stem primarily from differences in product specifications, quality grades, and brand positioning. For example, Shandong Haihua’s premium-grade (99.2% purity) quote differs from food-grade (99% purity) quotes; higher quotations by certain domestic producers (e.g., Henan Sentie) may reflect specialized specifications or brand premiums.

III. Outlook and Forecast
1. Short Term (1–2 Months)
- Light soda ash prices are expected to remain in a narrow consolidation range, with limited volatility. On the supply side, concurrent plant maintenance and restarts will lead to a modest net supply increase. On the demand side, weak downstream demand and absence of strong catalysts will constrain price upside. However, close monitoring is warranted for shifts in enterprise operational status and changes in downstream restocking rhythms—if concentrated restocking emerges, it could introduce short-term timing-based price fluctuations.

2. Medium Term (3–6 Months)
- Should high-cost production capacity exit the market substantively (e.g., shutdowns of ammonia-soda process plants), and if export volumes rise (projected 2026 exports: 2.19–2.60 million tons), supply-demand tensions may ease marginally. Nevertheless, inventory drawdown will require time, and the price center of gravity is unlikely to shift significantly upward in this horizon.

3. Long Term (1+ Years)
- The share of natural-alkali-process production is projected to rise to 25%, accompanied by increasing industry concentration. Consequently, price volatility will likely moderate, with the long-term price center of gravity trending downward. The floor support level may gradually decline toward RMB 1,100 per ton—the approximate cost floor for natural-alkali-process producers.
