Core Viewpoint - The conference highlighted the need for the chlor-alkali industry to address challenges such as regional imbalances, product structure issues, and the necessity for high-end product development during the "14th Five-Year Plan" period, advocating for a new paradigm of "high-end + collaborative" development [1][5]. Industry Overview - In 2024, there are 172 caustic soda production enterprises in China with a total capacity of 50.1 million tons, including an increase of 1.69 million tons. In the first half of 2025, the market remained stable with an additional 450,000 tons of capacity and a year-on-year production increase of 4.8%, reaching 22.67 million tons [2]. Market Supply and Demand - The South China caustic soda market is characterized by insufficient local production and reliance on external supply, with total capacity at 2.87 million tons, accounting for 5.69% of national capacity. The demand in Guangdong has surpassed 2 million tons, necessitating external support [3]. - The Guangxi region has a total caustic soda capacity of 1.145 million tons, primarily driven by the aluminum oxide industry, which is expected to see a significant increase in demand due to new production capacities coming online [3]. - The Fujian region has a caustic soda capacity of 1.44 million tons, meeting some local demand, while emerging industries like new energy and electronics are increasing the demand for caustic soda [3]. Systemic Challenges - The chlor-alkali industry faces systemic challenges including product structure imbalance, intensified market competition, and ongoing environmental constraints. Despite increased production and supply, key chlorinated products are operating below 70% capacity, indicating a persistent "alkali-chlorine imbalance" [5][6]. Development Strategies - To address these challenges, the industry must focus on expanding downstream products with high chlorine consumption and developing high-value, differentiated fine chemical products [6]. - The industry is urged to optimize market layouts to achieve supply-demand balance, enhance technological innovation for green development, and improve collaborative efficiency through smart transformation [7][8].
