Review of the polyaluminum chloride Market in 2025

According to SunSirs' commodity market analysis system: In 2025, the average market price of domestic solid (industrial grade, content ≥28%) polyaluminum chloride was 1,778.33 RMB/ton at the beginning of the year and 1,711.67 RMB/ton at the end of the year, representing a 3.75% decrease annually. The highest point during the year was 1,778.33 RMB/ton on January 1st, and the lowest point was 1,695.00 RMB/ton on September 21st, with a maximum fluctuation of 4.69% during the year.

The first half of the year saw a continuous decline: prices fell in a stepwise manner from February to July, dropping to 1,761.67 RMB/ton on February 10th. Prices briefly stabilized in the 1,745 RMB/ton range from March to May. The decline accelerated in June and July, reaching the year's lowest point of 1,695 RMB/ton on July 20th, a cumulative decrease of 4.69% compared to the beginning of the year.

Stabilization at a low level in the second half of the year: Prices remained at a low level of 1,695 RMB/ton in August and September. After October, supported by rising raw material costs and a marginal recovery in downstream demand, prices rose slightly to 1,711.67 RMB/ton and remained at this level until the end of the year.

Throughout the year, the price of polyaluminum chloride fell from its peak at the beginning of the year, with a year-on-year decrease of 3.75% by the end of the year. The overall market remained relatively weak.

Polyaluminum chloride market forecast for 2026

Cost side: According to SunSirs' commodity market analysis system, the domestic hydrochloric acid market experienced significant downward fluctuations in 2025. The average price at the beginning of the year was 110 RMB/ton, and the average price at the end of the year was 107.50 RMB/ton, representing a 2.27% decrease throughout the year. East China is one of the main hydrochloric acid production regions in China. Jiangsu Province, in particular, is a major base for hydrochloric acid production in China, with the highest output nationwide. The "14th Five-Year Plan for the Development of the Raw Materials Industry" issued by the National Development and Reform Commission clearly states the need to improve the comprehensive utilization of by-products in the chlor-alkali industry and encourages enterprises to build integrated circular systems to achieve efficient co-production of chlorine, hydrogen, and hydrochloric acid. This policy directly promotes the upgrading of the hydrochloric acid production model dominated by the chlor-alkali industry.

Supply side: According to incomplete statistics, China's polyaluminum chloride production capacity is mainly concentrated in provinces with well-developed raw material supply and industrial infrastructure, such as Henan, Shandong, and Jiangsu. Henan, as the core production area, accounts for over 40% of the national production capacity. The average capacity utilization rate of the industry throughout the year was approximately 55%-60%, which was relatively low. Small and medium-sized manufacturers were generally operating at less than 40% capacity due to rising environmental protection costs, financial pressure, and low-price competition, while leading enterprises, relying on their scale and technological advantages, can achieve capacity utilization rates of 70%-80%.

Demand side: The national "14th Five-Year Plan" for water ecological environment protection continued to be implemented, and projects such as the upgrading and renovation of urban sewage treatment plants and the treatment of black and odorous water bodies are accelerating, which will significantly boost demand in the water treatment sector. With the recovery of domestic consumption and the return of overseas orders, the operating rates of industries such as papermaking and printing and dyeing are expected to gradually rebound, driving an increase in the purchase volume of polyaluminum chloride. The promotion of high-efficiency polyaluminum chloride in the treatment of difficult-to-treat wastewater will increase the unit consumption of the product and simultaneously generate increased demand for high-end products.

Market outlook:

In 2026, the domestic aluminum polychloride market will likely exhibit a volatile recovery pattern under a weak equilibrium, with prices fluctuating within the current low range. The overall price level may be slightly higher than in the second half of 2025, but significant upward movement is limited.
