According to the Commodity Market Analysis System of Shengyi Society, the price of polyester filament fell and rebounded in July. As of July 31st, the mainstream polyester filament factories in Jiangsu and Zhejiang, POY (150D/48F), quoted at 6600-6800 yuan/ton, polyester DTY (150D/48F low elasticity) at 7800-8050 yuan/ton, and polyester FDY (150D/96F) at 6900-7200 yuan/ton.

price trend
In the first half of July, the production and sales of polyester filament remained at 30-50%. The effect of enterprises offering discounts on shipments was not good, and inventory continued to increase while prices declined. In the middle and late of the month, downstream users concentrated on replenishing warehouses, resulting in increased production and sales. The effect of enterprises reducing inventory was good, and the focus of transactions fluctuated upwards.
Cost end
The price of raw materials has a significant impact on polyester filament. In the first half of the month, the narrow range fluctuation support of crude oil was limited. As of July 30th, the average price of PTA market in East China was 4889 yuan/ton, a decrease of 3.79% from the beginning of the month.
Supply and demand side
In terms of supply, the leading polyester filament production enterprises implemented production cuts in July, and coupled with the pressure of inventory in the early stage, the subsequent operating load of the enterprises is expected to continue to decrease, which has eased the supply pressure to some extent. In terms of demand, in the first half of the year, the effect of companies offering discounts on shipments was poor, cash flow was compressed, and manufacturers began to sell at low prices, resulting in relatively firm quotes. Starting from the middle of the month, although July is generally in the off-season, the concentrated replenishment behavior downstream has led to an increase in production and sales of polyester filament, a decrease in inventory, and an increase in prices. The effect of enterprise destocking has been good, and the willingness to support the market has increased, which has also played a driving role in the price increase.
Future forecast
According to Business News, under the atmosphere of macroeconomic sentiment recovery at the end of the month, the buying sentiment was stimulated, and the demand side increased slightly, causing prices to fluctuate upwards. In the medium to long term, price recovery needs to wait for peak season orders to be fulfilled and tariff risks to become clear,

In July, the domestic fluorite price trend slightly declined. As of the end of the month, the average domestic fluorite price was 3137.5 yuan/ton, a decrease of 0.40% from the beginning of the month at 3706.25 yuan/ton, and a year-on-year decrease of 12.63%.

Supply side: Start production to maintain normal spot supply of fluorite
The current situation of the game in the domestic fluorite industry still exists. Overall, the operating rate of enterprises has increased. Upstream mining is tight, and backward mines will continue to be eliminated. In terms of new mines, mineral investigation work is still difficult. In addition, national departments need to rectify fluorite mines, and fluorite mining enterprises are facing increasingly strict safety and environmental protection requirements. The difficulty of operating fluorite mines has increased, and the shortage of raw materials has limited the operation of fluorite enterprises. However, with the rise of temperature, northern enterprises are gradually starting production, and the supply of fluorite enterprises on site has increased. The lack of active procurement has led to sufficient spot goods on site, and fluorite inventory on site has increased. In July, the fluorite market situation slightly declined.
Demand side: The price of hydrofluoric acid has declined, and the refrigerant market is still acceptable
In July, the domestic price of hydrofluoric acid declined, and the mainstream price negotiated in various regions of China was 10500-11000 yuan/ton. The downstream hydrofluoric acid equipment is still in shutdown, and there is little change in the spot supply of hydrofluoric acid. Manufacturers mainly purchase hydrofluoric acid on demand, and the overall production of hydrofluoric acid remains at around 50%. Fluorine enterprises maintain essential orders, and hydrofluoric acid enterprises are in a loss making state. They are not actively purchasing raw fluorite, and downstream merchants have a strong wait-and-see attitude. Both buyers and sellers have weak expectations for the future market due to poor demand digestion. The guidance price of hydrofluoric acid manufacturers remained low in August, and the fluorite price market was mainly affected by this news.
The downstream refrigerant market in the terminal industry is still promising, and the terminal policy of the refrigerant industry is being strengthened. Demand is expected to achieve substantial improvement. Fluorine chemical enterprises within quota control have strong confidence in raising prices in the refrigerant market. Currently, the pace of high price procurement is relatively slow, but the industry inventory is transmitting in a positive and orderly manner. Due to high prices, the enthusiasm for stocking up in the terminal industry is low, and upstream products are mainly purchased on demand. The trend of refrigerant market is average, while the fluorite market remains low.
In addition to the traditional demand in the refrigerant industry, fluorite, as an important mineral raw material for modern industry, is constantly developing in emerging fields. It is also applied in strategic emerging industries such as new energy and new materials, as well as in national defense, nuclear industry and other fields, including lithium hexafluorophosphate, PVDF、 Graphite negative electrodes, photovoltaic panels, etc., have received certain support in the application of fluorite due to the demand for new energy and semiconductors.
Market forecast: In the near future, it is difficult to improve the supply of domestic fluorite mines, and some mines have stopped production and undergone safety inspections. The tight supply of fluorite mines is a positive support for the fluorite market. However, in some areas, the lack of active fluorite procurement has led to an increase in inventory. In addition, downstream resistance to high prices is severe, and hydrofluoric acid enterprises mainly purchase on demand, with no actual increase in demand. In addition, the market price of hydrofluoric acid remains low. Overall, the fluorite market is mainly volatile in the short term.

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

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.

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.
