According to the Commodity Market Analysis System of Shengyi Society, from September 1st to 29th (as of 10:00), the average price of methanol in East China ports in the domestic market first increased from 2253 yuan/ton and then fell to 2260 yuan/ton, with a price increase of 0.30% and a year-on-year decrease of 10.26% during the period.
The domestic methanol market as a whole is showing a fluctuating and weak trend, and the performance of ports and the mainland market is showing phased differentiation. The import volume at the port remains high, and inventory pressure has not been substantially alleviated. The mainland market, on the other hand, is affected by supply and demand as well as cost factors, resulting in fluctuations. The continuous pressure on the supply side has led to the accumulation of inventory by enterprises, and the impact of pre holiday inventory and low-priced port sources has caused downstream only on-demand procurement, leading to a further decline in the market.

As of the close on September 28th, the closing price of methanol futures on Zhengzhou Commodity Exchange has risen. The main contract for methanol futures, 2601, opened at 2360 yuan/ton, with a highest price of 2367 yuan/ton and a lowest price of 2347 yuan/ton. It closed at 2364 yuan/ton in the closing session, up 12 yuan/ton or 0.51% from the previous trading day’s settlement. The trading volume is 170414 lots, the open position is 877555, and the daily increase position is -7577.
On the cost side, since early September, coal prices have gradually rebounded after weak consolidation at a low level. In addition to the disturbance of anti involution policies, there is good support for non electricity demand growth and downstream stocking before the Double Festival. The cost of methanol is influenced by favorable factors.
On the demand side, glacial acetic acid: The starting price of the northwest factory of glacial acetic acid has been raised by 40 yuan/ton, and the company’s shipments are smooth. Formaldehyde: The formaldehyde market is fluctuating. Dimethyl ether: The dimethyl ether market is running smoothly. Most downstream products are affected by methanol prices, and the impact on methanol demand is mixed.
On the supply side, the overall recovery exceeds the loss, resulting in an increase in capacity utilization. The supply of methanol is affected by favorable factors.
In terms of external markets, as of the close of September 25th, the CFR Southeast Asian methanol market closed at a price of 325.5-326.5 US dollars per ton. The FOB US Gulf methanol market closed at 100-101 cents per gallon; The closing price of the European FOB Rotterdam methanol market is 280.5-281.5 euros per ton.
According to future predictions, after the National Day holiday, the market will enter a critical stage of upstream companies destocking and downstream companies restocking simultaneously. In addition, external variables such as freight fluctuations and intensified competition in regional supply flow will cause market fluctuations to become more frequent. The methanol analyst from Shengyi Society predicts that the domestic methanol spot market will mainly consolidate.

According to the commodity analysis system of Shengyi Society, the styrene market has slightly declined this week, with an average price of 7184 yuan/ton at the beginning of the week and 7120 yuan/ton over the weekend, a decrease of 0.89% during the week.

The decline in spot prices in East China has narrowed, and low-priced transactions in Shandong are good. The weekly production has slightly decreased, the processing gap has fluctuated at a low level, port inventory has decreased, the fundamentals are still acceptable, spot prices are firm, and the basis has rebounded. However, high import volume expectations and poor downstream product profits have dragged down the market, resulting in weak expectations.
Supply and demand side: This week, the market has sufficient supply of goods, and port inventory has risen. Downstream stocking is nearing completion, cautious entry into the market, traders are watching closely, and transactions are weak
Styrene external market: On September 18th, the closing price of the styrene market in Asia remained stable, with a closing price of $835-845/ton FOB Korea and $845-855/ton CFR China.
Market forecast: In the future, there may be limited fluctuations in crude oil and raw materials, and downstream demand for styrene is lower than expected. With weak fundamentals, it is expected that the styrene market will consolidate and operate in the short term.

DOP prices have fluctuated and fallen, leading to high levels of consolidation in the operating load of DOP enterprises and an increase in DOP supply; The raw material isooctanol fluctuated and fell, the price of phthalic anhydride fluctuated and fell, the cost of DOP decreased, and the downward pressure on DOP weakened; Downstream demand is unlikely to improve, with mediocre intentions for DOP procurement inquiries and weak DOP demand transactions. The cost has decreased, and the price of plasticizers has fluctuated and fallen.
This week, the price of raw material isooctanol fluctuated and fell
According to the Commodity Market Analysis System of Shengyi Society, as of September 22, the price of isooctanol was 6983.33 yuan/ton, a fluctuating decrease of 0.95% compared to the price of 7050 yuan/ton on September 14. This week, the isooctanol enterprise equipment remained stable at a high level, and the operating rate of isooctanol equipment remained stable at 96%. The production capacity of isooctanol increased, and the supply of isooctanol increased; This week, the price of isooctanol fluctuated and fell, the cost of plasticizers decreased, and the downward pressure on DOP increased.
This week, the price of raw material phthalic anhydride remained weak and consolidated
According to the Commodity Market Analysis System of Shengyi Society, as of September 22, the quoted price of phthalic anhydride was 6293.33 yuan/ton, a slight decrease of 0.11% from the price of 6300 yuan/ton on September 15.

This week, the load of phthalic anhydride equipment has fallen, the operating rate of phthalic anhydride enterprises has decreased, the supply of phthalic anhydride has decreased, the price of phthalic anhydride has fallen, and the cost of plasticizers has decreased. The downward pressure on the price of plasticizer DOP has increased this week.
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 remained weak and consolidated. The downward pressure on the cost of plasticizer DOP still exists; In terms of supply, the operating rate of plasticizer enterprises is stabilizing 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. In the future, with strong supply and weak demand coupled with weakened cost support, it is expected that the price of plasticizer DOP will fluctuate and fall.

According to the Commodity Market Analysis System of Shengyi Society, the TDI market in East China has slowed down this week. As of September 19th, the average market price in East China was 13800 yuan/ton. On September 15th, the average price was 13866/ton, a decrease of 0.48% during the week and a year-on-year increase of 3.37%.
This week, the decline in the TDI market has decreased and the downward trend has slowed down. TDI major factories have stable production, stable market supply filling, and an increased willingness of suppliers to support prices, while the demand side remains weak. During the week, major factories in Shanghai suspended trading and reporting, boosting business confidence. Intermediaries often follow the market trend, while downstream companies, due to tightened profits and low market entry enthusiasm, are constrained by demand, resulting in a weak TDI market.

Supply side: The Yantai Wanhua TDI plant will be shut down for maintenance starting from August 19th, with an expected maintenance period of about 40 days. Other devices maintain stable operation.
Cost wise: The trading atmosphere in the toluene market is bearish, with average market transactions and limited guidance on news. There is a strong wait-and-see atmosphere.
In terms of future analysis, TDI data analysts from Shengyi Society believe that the current TDI price has fallen to a certain level, and industry players are becoming increasingly cautious in their operations. Under the supply-demand game, it is expected that the TDI market will narrow and consolidate in the short term.

Analysis: This week (9.8-12), the liquid ammonia market in Shandong region was weak, with prices continuing to decline and the decline slowing down compared to last week. According to the Commodity Market Analysis System of Shengyi Society, the main production area of Shandong experienced a weekly decline of 1.02%. Due to prominent supply pressure, market inventory remains at a high level. The maintenance equipment is partially in operation, and the overall supply performance is loose. In addition, some ammonia plants have increased their ammonia conversion capacity, and the accumulation of liquid ammonia continues to put pressure on the manufacturers. Manufacturers’ prices have gradually loosened during the week, and as the weekend approaches, the overall decline in prices for major factories in Shandong is around 100 yuan. Distributors mainly underreport shipments. And downstream procurement enthusiasm is not high, agricultural demand is still in the off-season, industrial demand remains rigid, and the overall demand side is bearish. At present, the mainstream quotation in Shandong region is between 2200-2350 yuan/ton.

Prediction: It is difficult to alleviate the supply pressure in the near future, coupled with the low operating rate of compound fertilizers downstream of liquid ammonia and limited recovery of phosphorus fertilizer production, which further limits the demand for liquid ammonia. Mainly follow up on agricultural and industrial demand. It is expected that liquid ammonia will continue to maintain a weak and volatile market.

According to the Commodity Market Analysis System of Shengyi Society, the mixed xylene market has fluctuated downward this week. From August 29 to September 5, 2025, the price of mixed xylene decreased from 5680 yuan/ton to 5560 yuan/ton, a decrease of 2.11%. The overall decline in the domestic mixed xylene market this cycle, coupled with a weak trend in the crude oil market during the week, has dragged down the mentality of the spot market. The main refineries in Shandong have slightly lowered their ex factory prices, attracting some downstream chemical and oil blending companies to purchase in the market, but overall trading is relatively low. During the week, there was a slight destocking in the East and South China regions, with main refineries experiencing a decline in ex factory prices and a weak atmosphere in the spot market.

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 xylene quotation summary shows that the company is currently operating normally, with stable production and sales. The company’s quotation remains unchanged from the previous day. As of September 5th, East China Company quoted 5700 yuan/ton, North China Company quoted 5600-5750 yuan/ton, South China Company quoted 5750 yuan/ton, and Central China Company quoted 5600-5650 yuan/ton.
Demand side:

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, and the macro performance is weak. The recent arrival of the supply side at the port has been good, with refineries operating at a high rate and overall supply being loose. The downstream chemical and oil blending industries on the demand side have recently shown weak purchasing intentions, with an overall preference for rigid demand. Overall, under the influence of loose supply, it is expected that the xylene market will continue to operate weakly in the near future.

According to the commodity analysis system of Shengyi Society, the market for locally refined petroleum coke has slightly increased recently. As of September 1st, the price of locally refined petroleum coke in the Shandong market was 2440.00 yuan/ton, an increase of 1.14% from 2412.50 yuan/ton on August 25th.

Recently, crude oil prices have fluctuated and risen, and the peak season for traditional fuel consumption in the United States is coming to an end. Coupled with the ongoing negotiations between Russia and Ukraine, the crude oil market is showing a downward trend.
Recently, the shipment of petroleum coke has been good, and the inventory of refineries is low; Downstream enterprises still have a demand for petroleum coke procurement: downstream aluminum carbon has a stable demand for petroleum coke, the negative electrode material market mainly purchases petroleum coke on demand, and graphite electrode enterprises have low production enthusiasm and limited petroleum coke procurement. Recently, the shipment of petroleum coke from ports has been acceptable, with an increase in spot goods at ports and a slight decline in coke prices.
Recently, the market for calcined coke has risen, with decent market transactions and support from downstream purchasing needs, resulting in low inventory levels for calcined coke enterprises.
Market forecast: Currently, the trading in the local refined petroleum coke market is still acceptable, with downstream procurement being the main demand, which still provides support for the petroleum coke market. It is expected that petroleum coke will mainly consolidate in the near future.

1、 Price trend

According to the Commodity Market Analysis System of Shengyi Society, the market price of pure benzene in Shandong Province first rose and then fell this month. In the first half of the month, market prices mainly increased, while in the second half, market prices mainly decreased. On August 1st, the price was 6075.33 yuan/ton; On August 29th, the price was 6012 yuan/ton, an increase of 1.04% from the beginning of the month.
2、 Market analysis
Pure benzene: The price of pure benzene in the domestic market has fallen today. The continuous impact of imported goods in the distant months on the domestic market has led to pessimistic futures trading, with low-level buying following paper goods and a lack of market confidence. Shandong’s local refining enterprises have lowered their quotations, resulting in average on-site transactions. Overall, there is a lack of willingness to purchase essential goods, and it is expected that pure benzene will fluctuate and consolidate in the short term. Actual transactions are subject to negotiation.
This month, Sinopec has lowered the price of pure benzene by 50 yuan/ton to 6000 yuan/ton.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market slightly rose in August. As of August 29th, the spot rubber market in China’s natural rubber market was around 14966 yuan/ton, an increase of 3.52% from 14458 yuan/ton at the beginning of the month. As of August 29th, the mainstream price for 24 years of Guangken, Baodao, and Haibao latex in Qingdao area is 14850~15200 yuan/ton.
The prices of Tianjian raw materials remained high in August. As of August 29th, the price of Thai glue was 55.45 baht/kg, a decrease of 1.00% compared to 55.00 baht/kg at the end of July. On the one hand, heavy rainfall and gusts in Thailand during the first half of August posed resistance to natural rubber (TSR) cutting activities, and on the other hand, the domestic cutting period coupled with unstable production from Vietnam’s old natural rubber plantations. The overall market supply of natural rubber raw materials is tight, and prices are firm, providing support for natural rubber.
The natural rubber inventory has fallen slightly in August, which has a bearish impact on the natural rubber market. As of August 24, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 606200 tons, a decrease of 5.34% from 640400 tons at the end of July.

Downstream tire production slightly increased in August, providing essential support for the natural rubber market. As of August 22, the construction of semi steel tires by domestic tire companies has slightly increased to around 7.40%; The construction of all steel tires by tire companies in Shandong Province has slightly increased to around 6.5%.
Market forecast: The current high prices of raw materials both domestically and internationally, as well as the increase in downstream tire production, provide support for the Tianjin rubber market. The Tianjin rubber port inventory has slightly decreased, and with the arrival of the peak season, it is expected that the natural rubber market will fluctuate and rise in the later period.
