Caustic Soda

Recent Dynamics in the Caustic Soda Market

1. **Price Trends**
- The domestic caustic soda market has overall maintained a stable-to-strong trend. In Shandong, the main ex-works price for 32% membrane caustic soda ranged from 750 to 800 RMB/ton, representing an increase of approximately 30–50 RMB/ton compared to earlier levels. The main ex-works price for 50% membrane caustic soda ranged from 1,250 to 1,300 RMB/ton, with a rise of 20–30 RMB/ton. Prices in Jiangsu for 32% membrane caustic soda also saw an upward movement, ranging from 780 to 820 RMB/ton.
- The price increase in liquid caustic soda is primarily driven by supply-side and cost factors. Partial plant maintenance or reduced operating loads have led to decreased local supply, while high prices for liquid chlorine have provided cost support for caustic soda production.

2. **Supply Situation**
- Several caustic soda enterprises have scheduled maintenance plans recently. For instance, a large caustic soda enterprise in North China plans to shut down its unit for 10–15 days, expected to reduce liquid caustic soda output by approximately 20,000–30,000 tons. Additionally, enterprises in East China have temporarily halted operations due to equipment failures, affecting output by around 10,000 tons.
- Overall, the industry’s operating rate has declined, with the national average currently at 78%–80%, a drop of 2–3 percentage points from previous levels. The supply side is showing a tightening trend.

3. **Demand Situation**
- The alumina industry is the primary consumer of caustic soda. Recently, firm alumina prices have sustained high production activity, leading to stable and increasing demand for caustic soda. Some alumina producers have increased procurement volumes to ensure continuous production.
- Demand in the papermaking and printing/dyeing industries has also shown signs of recovery. As downstream enterprises increase their operating rates, caustic soda purchases have gradually risen, although the overall incremental demand remains limited.

4. **Inventory Situation**
- Inventory levels at caustic soda enterprises have decreased. The total inventory of major caustic soda enterprises nationwide currently stands at 150,000–160,000 tons, a reduction of approximately 20,000–30,000 tons from earlier levels. This decline is mainly due to reduced supply and increased downstream demand, resulting in favorable sales and faster inventory digestion.

5. **Cost Factors**
- Liquid chlorine prices remain high, with Shandong region prices ranging from 1,000 to 1,100 RMB/ton, an increase of 100–150 RMB/ton compared to previous periods. The rise in liquid chlorine prices has increased caustic soda production costs, providing certain cost support for caustic soda prices.
- Energy costs, such as electricity and coal, remain relatively stable, having minimal impact on caustic soda costs.

Analysis and Judgment

1. **Supply Side**: The reduction in supply caused by enterprise maintenance and equipment failures is a key driver of the recent price increase in caustic soda. Until maintenance activities conclude, the tight supply situation is unlikely to be fundamentally alleviated, continuing to support prices.

2. **Demand Side**: Stable demand from the alumina industry and recovering demand from papermaking and printing/dyeing sectors provide strong support for the caustic soda market. However, the limited incremental demand makes it unlikely to drive significant price surges.

3. **Cost Side**: High liquid chlorine prices have increased production costs, giving enterprises incentive to raise prices to protect margins. Cost factors will to some extent limit the downside risk for caustic soda prices.

Forecast

1. **Short-Term (1–2 Weeks)**: Caustic soda prices are expected to remain stable-to-strong. Supply tightness and cost support will push prices higher. The main ex-works price for 32% membrane caustic soda in Shandong is likely to exceed 800 RMB/ton, while the price for 50% membrane caustic soda may reach 1,300–1,350 RMB/ton.

2. **Medium-Term (1–2 Months)**: As some enterprises complete maintenance, supply will gradually increase, potentially easing market supply-demand imbalances. However, if downstream demand from industries like alumina remains robust, prices will stay at relatively high levels, with narrower price fluctuations.

3. **Long-Term (3–6 Months)**: Attention should be paid to trends in liquid chlorine prices and downstream demand. If liquid chlorine prices decline and downstream demand growth slows, caustic soda prices may face downward pressure. Overall, assuming a balanced supply-demand environment, prices will fluctuate within a reasonable range.
