This week, the domestic acetone market experienced a rise followed by a decline. The domestic acetone market reported an average price of 4835 yuan/ton on July 21 and 4830 yuan/ton on July 28; The East China market dropped from 4770 yuan/ton to 4750 yuan/ton.

During the week, the raw materials of pure benzene and propylene fluctuated within the range, and the cost support weakened. Hengli Petrochemical’s phenol ketone unit was shut down for maintenance, and the operating rate of domestic phenol ketone factories slightly declined to 75%. In terms of ports, the replenishment of cargo is limited, and the port inventory has dropped to 20000 tons. The mentality of traders has been boosted, and the intention to sell low has weakened. The offer has slightly increased. The overall actual orders at the opening of the new week are limited, and there are some intentions to sell low. The current trading atmosphere is flat, and the trading volume needs to be released.
The operating rate of the downstream MIBK industry has increased, while the operating rate of MMA has declined with the reduction of negative load in the second phase of Zhejiang Petrochemical. The operating rate of the isopropanol industry has also shown a slight decrease. The solvent industry has been affected by high temperature weather and the rainy season in the south, and the overall demand for acetone has decreased. The downstream purchasing sentiment is not high, and they mostly follow up with urgent needs.
The acetone offers in major mainstream markets across the country on July 28th are as follows:
Region. Quotation on July 28th /Weekly increase and decrease
East China region / 4750./ 0
Shandong region / 4900./ -50
Yanshan region / 4900./ -50
South China region / 4900./ -50
In the new week, we will pay attention to the restart of Hengli Petrochemical’s phenol ketone unit, the maintenance of Shanghai Xisa unit, and the export of newly added production capacity from Zhenhai Refining and Chemical. Currently, the port inventory is low at 22000. From the demand side, there is an expected increase in terminal isopropanol and a slight upward trend in MMA. Overall, there has been little change in cost. From the perspective of Business Society, the short-term acetone market is mainly characterized by range fluctuations.

Supply side contraction

According to industry insiders, the Yichun Land and Resources Bureau recently issued a red headed document to verify the historical approval issues of lithium mining enterprises in its jurisdiction. The mining rights of at least 8 lithium mica mines may have problems such as non compliant approval processes, non-compliance with environmental standards, cross-border mining, and higher-level approval.
On the afternoon of July 17th, Zangge Mining (000408) announced that its wholly-owned subsidiary Golmud Zangge Potash Fertilizer Co., Ltd. received a notice from the Haixi Natural Resources Bureau and Haixi Salt Lake Management Bureau on July 16, 2025, ordering the immediate cessation of lithium resource development and utilization activities. The notice requires the company to strictly comply with national laws and regulations, fulfill its corporate responsibilities, immediately stop illegal mining activities and actively rectify them, and improve the legal procedures for lithium resources. After the lithium resource procedures are legal and compliant, apply to the Salt Lake Management Bureau of Haixi Prefecture for resumption of production. Only after the application is approved can production resume.
On the evening of July 21st, Jiangte Electric announced that its wholly-owned subsidiary Yichun Silver Lithium plans to start shutdown and maintenance on July 25th, involving all lithium salt production lines, with an expected maintenance period of about 26 days.
Jiangte Electric explained in the announcement that the core purpose of this shutdown and maintenance is to “reduce production costs and ensure the safe and stable operation of production equipment in the future”. During the maintenance period, Yichun Silver Lithium will organize a technical team to conduct a comprehensive inspection and maintenance of production equipment, and implement technical modifications to some equipment to improve the efficiency of production line operation. It is clearly stated that this maintenance is not expected to have a significant adverse impact on the annual business performance, and will not affect existing sales contracts and future supply in the near future.
Strong demand in overseas markets
The recovery of the European market and policy drivers
The growth rate of new energy vehicle sales in Europe has rebounded, coupled with intensified carbon emission policies (such as tightening carbon quotas in 2025), and it is expected that the market size of lithium batteries will reach 85 billion US dollars by 2025. In the field of energy storage, the installed capacity of household energy storage in Europe has increased by over 50% year-on-year, directly driving the demand for lithium salts. However, it should be noted that the expansion of domestic lithium salt production capacity in Europe (such as Northvolt’s plan to achieve a self-sufficiency rate of 90% by 2030) may weaken its dependence on imported lithium salts from China.
The outbreak of the Southeast Asian market and the reconstruction of the industrial chain
Indonesia, Malaysia and other countries have attracted CATL and BYD to build factories through policies, with plans to build 140GWh of battery production capacity by 2030, directly driving demand for lithium salts. Taking Indonesia as an example, its nickel resource advantage and battery production capacity planning are synergistic, and it is expected that the import volume of lithium salts will increase by more than 30% year-on-year in 2025. However, due to the scarcity of local lithium resources in Southeast Asia, it still needs to rely on imports of lithium salts from China in the short term.

Lithium carbonate data analysts believe that under the influence of the “anti involution” policy, there has been a small-scale production reduction in the domestic lithium carbonate supply side. However, in the long run, overseas South American salt lake lithium extraction projects will be put into operation in the fourth quarter, which may suppress the rebound space. Specific changes in market supply and demand still need to be monitored.

This week, the price of isooctanol has been consolidating strongly

According to the Commodity Market Analysis System of Shengyi Society, as of July 21st, the price of isooctanol was 7650 yuan/ton, a decrease followed by an increase of 0.66% compared to the price of 7600 yuan/ton on July 11th.

In the future, as the supply of isooctanol increases and demand recovers, the price of isooctanol will experience strong fluctuations and consolidation.

According to the monitoring of the commodity market analysis system of Shengyi Society, the price of activated carbon at the beginning of the week was 12700 yuan/ton, and the price of activated carbon at the end of the week was 12800 yuan/ton, with a price increase of 0.79%.

Most domestic manufacturers of activated carbon have seen price increases this week, with the ex factory price of activated carbon for coconut shell water purification in East China ranging from 9000 to 13000 yuan/ton. Coconut supply is insufficient in most parts of Asia, coupled with demand growth in industrial waste gas treatment, sewage treatment, lithium battery negative electrode materials, and other fields, leading to a surge in demand for environmentally friendly materials in emerging markets.
Internationally, Southeast Asia, as the main source of coconut shells worldwide, is expected to experience multiple natural disasters in 2024. Thailand’s reduced production of fragrant coconut due to drought and pest infestations, coupled with rising transportation costs, has led to a surge in coconut shell purchase prices, resulting in a yield rate of only 20% -30%.
Prediction: Due to the shortage of raw materials and insufficient production, it is expected that the price of activated carbon will mainly fluctuate with a strong trend in the short term.

According to the Commodity Market Analysis System of Shengyi Society, on July 15th, the ex factory price of cyclohexanone in Shandong Province, China was referenced at 7075 yuan/ton.
