1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The domestic economic data in May still showed resilience, and the Fed continued to pause rate cuts in its June meeting. Attention should be paid to the situation in the Middle East and changes in US tariff policies. In the supply - demand aspect, the quantity of low - concentration caustic soda delivered to major downstream industries in Shandong Province is expected to remain high this week, with non - aluminum downstream industries and traders resistant to high prices. There are both newly - added maintenance enterprises and downstream enterprises in the province, which is expected to have limited impact on the market. After the new alumina production capacity is put into operation, the demand has increased. The market has an expectation of continued price cuts, but the expectation is not too bad. Overall, the supply - demand situation in the liquid caustic soda market has changed little, lacking new support, and the caustic soda 2509 contract may continue to operate at a low level. The upper reference pressure level is 2,500 yuan/ton, and the lower support level is 2,200 yuan/ton [4]. 3. Summary According to the Table of Contents 3.1 Market Review - **Spot Market**: The price of Shandong liquid caustic soda has declined, and the basis of 32% liquid caustic soda in Shandong has converged. The prices of 32% ion - membrane caustic soda, 50% ion - membrane caustic soda, 98% flake caustic soda, liquid chlorine, and alumina in Shandong have all decreased to varying degrees, with the price of liquid chlorine dropping by 98%. The prices of raw salt and viscose staple fiber remained unchanged [9][12][18]. - **Futures Market**: The report presents the price trends of caustic soda futures contracts compared with those of soda ash, alumina, PVC, and the change in caustic soda warehouse receipt quantity [15]. 3.2 Market Analysis - **Supply Side**: In the week from June 13 - 19, 2025, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 81.2%, a month - on - month increase of 0.3%. Some enterprises in Central China, North China, and Northeast China temporarily reduced production or were under maintenance, while those in the Northwest and East China increased their loads after equipment maintenance. It is estimated that the capacity utilization rate in North China will slightly increase to about 81.8% this week, with a weekly output of about 798,600 tons [20]. - **Downstream (Alumina)**: The supply of alumina has decreased. An alumina enterprise in the southern region reduced its production capacity due to ore issues, slightly intensifying the tight supply situation in the south. As of June 19, the built - in production capacity of Chinese alumina was 112.4 million tons, the operating production capacity was 87.55 million tons, and the operating rate was 77.89% [26]. - **Inventory**: As of June 19, 2025, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in China was 366,500 wet tons, a month - on - month decrease of 9.57% and a year - on - year decrease of 5.63%.

Group 1: Report Core View - The overall comprehensive profit of caustic soda was relatively high in the first quarter of this year, and enterprises had a weak willingness to reduce production through maintenance, mostly maintaining high operation rates [4][10] - The cost of caustic soda mainly consists of raw salt and electricity prices. After the Spring Festival, the price of raw salt decreased slightly. With the continuous decline of coal prices, the production cost of caustic soda for enterprises with self - supplied power plants may further decrease, and the expectation of loss - induced production reduction is difficult to occur [4][10] - The downstream terminal demand was significantly weaker than the same period last year. The weak demand led to a continuous decline in caustic soda prices. The demand for alumina also declined due to cost - related maintenance and production reduction of some alumina enterprises, and the short - term stocking demand for caustic soda in alumina plants was weak [4][10] Group 2: Upstream Device Maintenance and Production Reduction - Upstream production enterprises generally conduct a large - scale routine maintenance every 2 - 3 years and a small - scale production line rotation inspection every year. In the first quarter of this year, due to high comprehensive profits, most enterprises maintained high operation rates [4][10] Group 3: Cost and Profitability - The cost of caustic soda is mainly composed of raw salt and electricity prices. After the Spring Festival, the price of raw salt decreased slightly, with the price of raw salt in surveyed chlor - alkali enterprises ranging from 280 - 300 yuan/ton (delivered). The cost of self - supplied power plants is lower, and with the decline of coal prices, the production cost of caustic soda may further decrease [4][10] Group 4: Downstream Demand - The downstream terminal demand was significantly weaker than last year. The weak demand led to a continuous decline in caustic soda prices. Downstream enterprises and traders were cautious in purchasing, mainly for rigid demand. Non - aluminum terminal inventories were generally low, showing a "buy on rising, not on falling" mentality [4][10] - Recently, the price of alumina was low, and some alumina enterprises reduced production due to cost issues, dragging down the rigid demand for caustic soda. Alumina plants had high inventories of caustic soda raw materials, and the short - term stocking demand was weak [4][10] Group 5: Specific Situation of Surveyed Enterprises Caustic Soda Enterprise A - It has a designed capacity of 150,000 tons and an actual capacity of 200,000 tons, with chloroacetic acid as the downstream chlorine - consuming product and some liquid chlorine sold externally [11] - It purchases industrial electricity externally, with a production electricity price of over 0.6 yuan, a delivered price of raw sea salt of 300 yuan/ton, and a comprehensive production cost of about 2,400 yuan/ton [11] - The current direct sales ratio is about 60% - 70%, with a target of 80% [12] Caustic Soda Enterprise B - It has a capacity of 200,000 tons, with CPE as the downstream chlorine - consuming product and a small amount of liquid chlorine sold externally [13] - It has a storage capacity of 15,000 tons, a normal inventory level of 5,000 tons, and an inventory of about 2,000 - 3,000 tons during the survey [14] - It purchases electricity externally, with a delivered price of sea salt for production of 250 - 260 yuan/ton and a full production cost of caustic soda between 2,300 - 2,400 yuan [14] - It is expected that liquid chlorine will bottom out and rebound, with a minimum price of - 350 yuan. In April, there were few export orders, and the export outlook for May was not optimistic [16] - During the survey, it was believed that the spot price of caustic soda could still rise, but the duration might be short. Qingdao Bay planned to officially put into operation 200,000 tons in May, and Jinling planned to start the 50% caustic soda device on April 19th [17] Enterprise C (Caustic Soda Flakes Trader) - It is a secondary trader of caustic soda flakes, mainly sourcing from Inner Mongolia and Shaanxi. During the survey, the social inventory of caustic soda flakes in Shandong was low due to traders' pessimistic expectations [18] - The freight from Inner Mongolia to Shandong is 240 - 260 yuan/ton excluding tax, and from Xinjiang to Shandong is 480 yuan/ton. Shandong's caustic soda flakes mainly come from Inner Mongolia [18] - It has a short - term bearish view on the market, and the price of caustic soda flakes in Inner Mongolia was 3,250 yuan/ton during the survey, with an expected further decline [18] Enterprise D (Liquid Chlorine Trader) - It is a liquid chlorine trader. Due to the high requirements for production and transportation, the threshold for liquid chlorine traders is high [19] - The sales radius is generally within 300 kilometers. Liquid chlorine is usually shipped on the same day or the next day without inventory [19] - It is expected that liquid chlorine will not decline too much in the short term and may rebound to 1 - 100 yuan/ton, with a fluctuation range between - 300 and 200 yuan/ton. The liquid chlorine markets in Shandong and Jiangsu are differentiated, and summer is a relatively off - season for small liquid chlorine - consuming enterprises [21]
