(Note: The cycle refers to the period from September 1, 2011 to present)
2、 Market analysis
This week, the price of bromine is running weakly, with a reference price of 28000-30000 yuan/ton for spot bromine production in Shandong region. Due to weather and policy reasons, bromine companies have tight inventory, while downstream companies have average purchasing enthusiasm. In terms of raw materials, domestic sulfur prices have been declining, with an average market price of 2654.33 yuan/ton at the beginning of the week and 2644.33 yuan/ton at the end of the week, a decrease of 0.38% and an increase of 90.1% compared to the same period last year. Downstream demand is generally average.
Prediction: Bromine prices are expected to be weak in the near future, while upstream sulfur prices are expected to be weak. Bromine prices are expected to remain stagnant this week, while downstream purchases are expected to be made on demand. Overall market activity is average. It is expected that bromine may continue to operate weakly in the later period, depending on downstream market demand.

According to the Commodity Market Analysis System of Shengyi Society, the toluene market fluctuated downward from August 29 to September 5, 2025. On August 29th, the benchmark price of toluene was 5440 yuan/ton, and on September 5th, the benchmark price of toluene was 5360 yuan/ton, a decrease of 1.47%. The toluene market fluctuated weakly in this cycle, and the weakening of crude oil in the second half of the week dragged down market sentiment, causing market prices to continue to decline. The Shandong region has been dragged down by the crude oil market this week, resulting in an overall decline in prices. Negotiations in the East China region are quiet, and offers are generally low. Affected by loose supply, the enthusiasm for downstream market entry in southern China is weak, and the prices of main refineries have been lowered, resulting in an overall weak market atmosphere.
Cost wise: The crude oil market prices in this cycle have mainly fluctuated at low levels. As of the 4th, the settlement price of the October WTI crude oil futures contract in the United States was $63.48 per barrel, and the settlement price of the November Brent crude oil futures contract was $66.99 per barrel. The crude oil market is influenced by both long and short factors. On the one hand, geopolitical factors remain one of the important factors affecting the crude oil market, and the Russia Ukraine issue has led to a strong operation of the crude oil market. On the other hand, Saudi crude oil may increase production, leading to an increase in US crude oil inventories. In addition, with the end of the peak oil season in the US, the global economic outlook and oil demand are not optimistic, putting pressure on crude oil market prices.

Supply side:
Sinopec’s toluene enterprise is operating normally, with stable production of equipment and many products for personal use, resulting in stable production and sales. As of September 5th, East China Company quoted 5350 yuan/ton, North China Company quoted 5300 yuan/ton, South China Company quoted 5300-5400 yuan/ton, and Central China Company quoted 5450 yuan/ton.
Demand side:
On September 5th, Sinopec Sales Company temporarily stabilized the price of xylene, with the current execution price of 7200 yuan/ton. This price is implemented in East China, North China, Central China, and South China. Yangzi Petrochemical, Zhenhai Petrochemical and other units are operating stably and sales are normal. As of September 4th, the closing prices of the para xylene market in Asia were $803-805/ton FOB Korea and $828-830/ton CFR China.
Market forecast: The recent trend of the crude oil market is weak, with limited boost to the spot market and a weak macro outlook. From the perspective of supply and demand, the recent performance has also been weak, with downstream demand being more rigid and lacking demand support. It is expected that the toluene market will continue to operate weakly in the short term.

According to the Commodity Market Analysis System of Shengyi Society, the price of lithium carbonate has fluctuated sharply recently. As of September 2nd, the benchmark price of battery grade lithium carbonate in Shengyi Society was 77233 yuan/ton, a decrease of 7.76% from last week, an increase of 8.27% month on month, and a decrease of 6.72%; The benchmark price of industrial grade lithium carbonate trading company is 75500 yuan/ton, a decrease of 8.11% compared to last week, an increase of 7.4% month on month, and a year-on-year decrease of 6.09%.

Supply side disturbances become the dominant factor in short-term prices
In early August, Ningde Times’ Jianxiawo mining area in Yichun, Jiangxi (one of the largest lithium mica mines in China) ceased production on August 9th due to the expiration of its mining license, and it will take at least three months to resume production. This news became an important trigger for price rebound. ​
At the same time, the compliance rectification of lithium mines in Yichun area (8 mining enterprises are required to rectify within a time limit), the illegal mining and production stoppage of Zangge Mining, and the reduced production of Jiangte Electric Machinery due to maintenance, as well as the “anti internal competition” policy of the Ministry of Industry and Information Technology to eliminate low-priced and disorderly production capacity, have led to strong expectations of supply contraction in the market, driving prices to rise rapidly. The price of battery grade lithium carbonate once rebounded from 60000/ton to 80000/ton.
But the resumption of production of Yichun Silver Lithium by Jiangte Electric has broken this expectation. As an important enterprise in the field of mica lithium extraction, its resumption of production means that market supply will increase again, leading to a drop in lithium carbonate prices from 80000 yuan/ton to 70000 yuan/ton. The frequent changes on the supply side have led to significant price fluctuations in recent times.
The demand is steadily increasing, but the growth rate is not as fast as the supply
In August, the production of downstream positive electrode factories increased by 4% -5% month on month, and the demand was slightly better than market expectations, with good demand on the energy storage side. In terms of the terminal market, sales of new energy vehicles have maintained impressive performance. However, based on data from recent months, the year-on-year sales growth rate has slightly decreased compared to the previous month.
In August, the monthly total production of lithium carbonate in China reached a new high, breaking through the 85000 ton mark, with a month on month increase of 5% and a significant year-on-year increase of 39%. The current market is still in a stage of structural supply-demand mismatch.
The lithium carbonate data analyst from Shengyi Society believes that the impact of mining shutdowns has not yet been fully transmitted to the supply and demand side. The key point of subsequent price fluctuations lies in whether the relevant mines can successfully complete the reserve verification report on September 30th and the subsequent changes in mineral types. In the short term, lithium carbonate is expected to fluctuate, and specific market changes still need to be monitored.

The price of plasticizer DOP fluctuated and fell in August

According to the Commodity Market Analysis System of Shengyi Society, as of August 29th, the DOP price was 7617.50 yuan/ton, a fluctuating decrease of 4.25% compared to the DOP price of 7955.83 yuan/ton on August 1st. The prices of raw materials isooctanol and phthalic anhydride have fluctuated and fallen, and the downward pressure on DOP prices has increased; In August, the operating load of DOP enterprises was consolidated at a high level, resulting in an increase in DOP production and supply; Downstream demand is difficult to improve, and there is a lack of interest in DOP procurement inquiries, resulting in limited improvement in DOP demand transactions. The increase in supply led to a decrease in costs, and the price of plasticizers fluctuated and fell in August.
The price of raw material isooctanol fluctuated and fell in August
According to the Commodity Market Analysis System of Shengyi Society, as of August 29th, the price of isooctanol was 7283.33 yuan/ton, a fluctuating decrease of 3.32% compared to the price of 7533.33 yuan/ton on August 1st. In August, the production capacity of isooctanol enterprises increased, and the operating rate of isooctanol equipment increased from less than 80% in July to 95% at the end of August. In addition, with the addition of new production capacity of isooctanol, the supply of isooctanol has increased; Downstream plasticizer companies are operating at a high level of consolidation, and the demand for isooctanol by plasticizers is recovering. As supply increases and demand rebounds, the price of isooctanol fluctuated and fell in August. The cost of plasticizers has decreased, and the downward pressure on DOP has increased.
Raw material phthalic anhydride prices hit bottom and rebounded in August
According to the Commodity Market Analysis System of Shengyi Society, as of August 29th, the price of phthalic anhydride in neighboring countries was 6300 yuan/ton, a fluctuating decrease of 5.26% compared to the price of 6650 yuan/ton on August 1st. In August, the price of ortho benzene fluctuated and fell, while the price of industrial naphthalene hit the bottom and rebounded. The cost support of phthalic anhydride was significant. In August, the equipment load of phthalic anhydride stabilized at a low level, and the operating rate of phthalic anhydride enterprises was about 60%. The supply of phthalic anhydride decreased, and the equipment operating load of downstream plasticizer enterprises stabilized at a high level. The demand support for phthalic anhydride still exists. Supply reduction and cost reduction led to a rebound in phthalic anhydride prices in August. The price of raw material phthalic anhydride hit bottom and rebounded, while the cost of plasticizers stopped falling and rebounded. The downward pressure on the price of plasticizer DOP weakened in August.
Future expectations
According to the data analyst of Shengyi Society’s plasticizer products, in terms of cost, the price of isooctanol has fluctuated and fallen, while the price of phthalic anhydride has bottomed out and rebounded. The downward pressure on the cost of plasticizer DOP still exists; On the supply side, the operating rate of plasticizer enterprises is consolidating at a high level, the production of plasticizers is increasing, and the supply of plasticizers is sufficient; In terms of demand, the overall economy is sluggish, coupled with anti competitive competition and the elimination of outdated production capacity, resulting in weak downstream demand. Overall, with strong supply and weak demand, coupled with the pressure of cost decline, it is expected that the price of plasticizer DOP will fluctuate and fall in the future.

1、 Price trend

According to the Commodity Market Analysis System of Shengyi Society, as of August 29th, the average quotation price of domestic high-quality DMF enterprises was 4110 yuan/ton, a decrease of 0.24% compared to the same period last month. Currently, DMF manufacturers are mainly operating steadily, with a narrow and weak trend. The DMF market is currently operating narrowly and weakly, with a stable focus on negotiations and a general purchasing atmosphere.
2、 Cause analysis
In terms of the market, the DMF market as a whole operated weakly in August, with a narrow downward trend in prices and insufficient driving force for price increases. Currently, the DMF market is mainly operating steadily.
Upstream: The price of methanol in the upstream market has remained stable with small fluctuations. As of August 29th, the price of methanol in Sinopec Great Wall has been reported as 1950 yuan/ton, and the 600000 ton/year methanol plant is currently operating at full capacity. Qinghai Zhonghao Methanol has no quotation at the moment. The 600000 ton/year natural gas to methanol plant has been shut down since October 23, 2024, and the restart time is uncertain. The ex factory price of methanol in Jining is based on the reference of 2260-2260 yuan/ton in cash withdrawal from the factory, and the price for Linyi delivery is based on 2320 yuan/ton. The 250000 ton/year coke oven gas to methanol plant in Shanxi Junjie (Jinhui) is stable
3、 Future forecast
DMF analysts from Shengyi Society believe that in the short term, the DMF market will mainly maintain stable prices, with insufficient support from the upstream cost side and downstream replenishment based on demand. The overall market operation is cautious.

According to the Commodity Market Analysis System of Shengyi Society, from August 15th to 22nd, MTBE prices fell from 5060 yuan/ton to 5020 yuan/ton, with a price drop of 0.79% during the cycle, a month on month drop of 0.35%, and a year-on-year drop of 18.37%. The domestic MTBE market is experiencing weak fluctuations. Local large manufacturers have ended their export port consolidation, resulting in an increase in MTBE external sales and gradually abundant resource supply. However, the demand for gasoline terminals is not performing well due to negative factors such as weak crude oil. Operators are purchasing relevant gasoline components on demand, and MTBE manufacturers are offering discounts to promote sales.

On the cost side, in terms of crude oil: the international oil price has fallen, and the main negative factors are the positive signals released by the Russia Ukraine peace talks, which are expected to further ease the geopolitical situation and weaken support for oil prices. As of August 21st, the settlement price of Brent crude oil futures for the October contract was $67.67 per barrel.
On the demand side, in terms of downstream gasoline, crude oil is weak and volatile, and the expected retail price limit for this round has been lowered. As the summer is coming to an end, the frequency of public travel is beginning to decrease. The MTBE demand side is affected by bearish factors.
Supply side: MTBE manufacturers in Henan and the Huizhou plant have started production, which has affected this week’s output and led to an increase in plant operating rates. The short-term domestic MTBE supply is affected by favorable factors.
As of the close on August 21st, the closing price of the Asian MTBE market has increased by $10.46 per ton compared to the previous trading day, with FOB Singapore closing at $664.91-666.91 per ton. The closing price of the European MTBE market increased by $10.75/ton compared to the previous trading day, and FOB ARA closed at $837.99-838.49/ton. The closing price of the MTBE market in the United States increased by $16.43/ton compared to the previous trading day, and the FOB Gulf offshore price closed at $784.36-784.71/ton (221.47-221.57 cents/gallon).
Future forecast: Currently, some manufacturers still have export support for the market, but as the summer season approaches its end and gasoline demand becomes weaker, MTBE analysts from Shengyi Society believe that the domestic MTBE market is mainly weak and consolidating.

The domestic acetone market continues to be weak. From the perspective of the national acetone market, the daily quoted price was 4780 yuan/ton on August 15th to 4720 yuan/ton on August 22nd, a decrease of 1.26%. The East China region shows a trend of first falling and then rising.

The domestic acetone market has experienced a narrow decline, with Sinopec companies lowering their listed prices by 100 yuan/ton to 4700 yuan/ton within the week. As of the weekend, the total volume of acetone shipments in East China in August was 41000 tons, with less than 10000 tons in transit. During the week, raw material products slightly declined and cost support weakened, but phenol ketone manufacturers are still in a loss making state, with a production rate of around 75%. Downstream factories are mainly in urgent need, with average production and little intention to stockpile goods, and focus on following up on small orders.
The acetone offers in major mainstream markets across the country on August 22nd are as follows:
Region. Quotation on August 22nd /8.15-22
East China region / 4630./ -80
Shandong region / 4720./ -50
Yanshan region / 4720./ -100
South China region / 4800./ 0
From the perspective of Business Society, it is expected that acetone will remain strong next week. From the supply side, there has been little change in domestic equipment, with a phenol ketone operating rate of 78%, imported resources gradually replenished, and port inventory maintained at a high level. From the perspective of demand, downstream bisphenol A and isopropanol units have seen some improvement, while MIBK has not fluctuated significantly. However, overall procurement is still mainly based on demand, but with the passing of high temperature weather, the overall demand for solvent products will improve. From a cost perspective, the pure benzene market is weakening. At present, the acetone market is at a low level, and it is expected that the acetone market will remain stable or have a narrow upward trend next week.

This week, the domestic phenol market remained stable with slight fluctuations, and the atmosphere was slightly weak. As of August 8th, the reference price in the East China market was between 6590-6620 yuan/ton. From the cost perspective of the week, the price trend of raw material pure benzene is relatively strong. Although there is support on the cost side, the intention of terminal procurement is weak, and there is a lot of pressure on traders to ship. However, considering the delay of domestic shipping due to the impact of the typhoon, traders have limited room to make concessions. Therefore, the domestic phenol market has shown a situation of large stability and small movements this week, and the trading atmosphere is light.
In terms of equipment, Shanghai Xisa has restarted, Dalian Hengli has increased its load, and Zhenhai Refining and Chemical has increased its supply.
As of August 8th, the phenol offers in mainstream markets across the country are as follows:
Region. Quotation on August 8th /Rise and fall from August 1st to 8th
East China region / 6610./ -30
Shandong region./6700./0
Surrounding areas of Yanshan Mountain / 6700./ -30
South China region/6650./0
Business Society expects that in terms of cost, the short-term expectation for pure benzene will be strong, and the cost will be supported. From a demand perspective, downstream demand for bisphenol A is expected to increase, while overall there is little fluctuation. From a supply perspective, the expected supply volume is expected to increase slightly. It is expected that phenol will experience slight fluctuations next week, with overall supply and demand remaining relatively stable. The phenol market price is expected to remain stable with small fluctuations.

The price fell by 0.59% during the cycle, 5.99% month on month, and 5.18% year-on-year. The domestic methanol market is showing signs of recovery. Northwest olefin factories are increasing their external procurement volume, coupled with favorable effects such as ongoing maintenance of some facilities and low inventory levels in enterprises. Upstream companies are selling at high prices, while downstream companies are passively following suit.
As of the close on August 1st, the closing price of methanol futures on Zhengzhou Commodity Exchange has fallen. The main contract 2509 for methanol futures opened at 2403 yuan/ton, with a highest price of 2417 yuan/ton and a lowest price of 2385 yuan/ton.

The trading volume is 505219 lots, with a position of 533076 and a daily increase of -31338.
On the cost side, coal supply has slightly decreased but the impact is limited, demand release is slow, and cost support is weak and stable. The cost of methanol is influenced by negative factors.
On the demand side, glacial acetic acid: The market price of glacial acetic acid is fluctuating, with a price increase of 50 yuan/ton at the Northwest factory. Formaldehyde: The formaldehyde market continues to remain stable. The strength of raw material methanol has increased, resulting in higher costs. Dimethyl ether: The dimethyl ether market is running smoothly. Most downstream products have been affected by the rise in methanol prices, and the demand for methanol is biased towards favorable factors.
On the supply side, the overall recovery exceeds the loss, resulting in an increase in capacity utilization. Negative factors affecting the methanol supply side.
In terms of external markets, as of the close of July 30th, the CFR Southeast Asian methanol market closed at a price of 332.50-333.50 US dollars per ton. The closing price of the US Gulf methanol market was 95-96 cents/gallon, down 1 cent/gallon; The closing price of FOB Rotterdam methanol market is 245.5-246.5 euros/ton, up 7 euros/ton.
In the future market forecast, enterprises have a clear willingness to raise prices, but traditional downstream industries are resistant to continuous price increases, which to some extent suppresses the room for price increases. Business Society’s methanol analyst predicts that the domestic methanol spot market is expected to strengthen and consolidate.
