According to the Commodity Market Analysis System of Shengyi Society, the domestic adipic acid market rebounded in August, mainly oscillating upwards. On August 1st, the average price of adipic acid in the domestic market was 7233 yuan/ton. On August 26th, the average price of adipic acid in the domestic market was 7383 yuan/ton, with a price increase of 2.07%.
The good news still exists, and the adipic acid market fluctuated and rose in August
At the beginning of August, the prices of pure benzene and cyclohexanone raw materials for adipic acid rose, supported by the increase in terminal rigid demand. The adipic acid market ushered in an upward trend, with prices rising to 7300 yuan/ton, an increase of nearly 1%. Approaching mid month, the support effect of raw material market is limited, and terminal demand has fallen. After the rise of adipic acid market, it gradually stabilizes, and the price continues to be 7300 yuan/ton, with no fluctuations in the market.
In the middle of the month, the prices of pure benzene and cyclohexanone raw materials for adipic acid fell weakly, and the demand for terminal rigidity was sluggish. The domestic adipic acid market had average transactions, but sales were still acceptable. The quotations of adipic acid production enterprises are relatively stable, while the overall quotations of traders have mainly declined. The market is running weakly, and as of August 19th, the price has fallen to 7200 yuan/ton, a decrease of nearly 0.5%.
At the end of the month, the market for pure benzene and cyclohexanone raw materials for adipic acid stopped falling and stabilized, with improved terminal demand and improved transactions in the domestic adipic acid market, resulting in increased sales. Adipic acid prices have risen one after another, and the market has rebounded. As of August 26th, the average market price has exceeded 7300 yuan/ton, with an overall increase of over 100 yuan/ton.
An analyst from Shengyi Society believes that in September, with an increase in terminal demand and a boost in raw material prices, the domestic adipic acid market is expected to continue to strengthen.

This week, the phthalic anhydride market has stopped falling and rebounded
According to the Commodity Market Analysis System of Shengyi Society, as of August 22, the price of phthalic anhydride in neighboring countries was 6250 yuan/ton, a fluctuating decrease of 0.79% compared to the price of 6300 yuan/ton on August 15. This week, the price of phthalic anhydride fluctuated and fell, while the price of industrial naphthalene fluctuated and stabilized. The cost support of phthalic anhydride still exists. The equipment load of phthalic anhydride increased this week, and the operating rate of phthalic anhydride enterprises stabilized. The supply of phthalic anhydride is sufficient, and the downstream plasticizer market fluctuated and fell. The equipment operating load of plasticizer enterprises decreased, and the demand support for phthalic anhydride weakened. With an increase in supply and a decrease in demand, coupled with a decrease in costs, the price of phthalic anhydride fluctuated and fell this week.
The cost of phthalic anhydride has decreased, and the supply is sufficient
As of August 15th, Sinopec’s ortho benzene quotation was 6300 yuan/ton, a fluctuating decrease of 1.56% compared to last weekend’s ortho benzene quotation of 6400 yuan/ton. The price of industrial naphthalene is stabilizing, the price of ortho benzene is falling, and the cost of phthalic anhydride is decreasing. The pressure of phthalic anhydride decline still exists, and the price of phthalic anhydride is falling. The price of naphthalene phthalic anhydride is 5900-6100 yuan/ton, and the price of ortho phthalic anhydride is 6100-6300 yuan/ton. This week, the operating load of phthalic anhydride equipment has resumed, the operating rate of phthalic anhydride enterprises has increased, and the supply of phthalic anhydride is sufficient.
Demand side: Downstream production decreases, DOP prices fluctuate and fall
According to the Commodity Market Analysis System of Shengyi Society, as of August 22, the DOP price was 7734.16 yuan/ton, a fluctuating decrease of 0.32% compared to the DOP price of 7759.16 yuan/ton on August 15. This week, the operating load of DOP enterprises has decreased, the production of DOP has decreased, the demand for phthalic anhydride has decreased, and the support for the rise in phthalic anhydride prices has weakened.
Future forecast
According to the data analyst of Shengyi Society’s phthalic anhydride products, in terms of demand, plasticizer companies have seen a decrease in production, a reduction in plasticizer output, and a decrease in demand for phthalic anhydride; On the supply side, the equipment operating load of phthalic anhydride enterprises has increased, leading to an increase in phthalic anhydride supply. In terms of cost, the price of ortho benzene has decreased, and the cost of phthalic anhydride has decreased. In the future, with an increase in supply and a decrease in demand for phthalic anhydride, coupled with a decrease in costs, it is expected that the price of phthalic anhydride will remain low and consolidate.

According to the Commodity Market Analysis System of Shengyi Society, the mixed xylene market has been operating weakly this week. From August 8th to August 15th, 2025, the price of mixed xylene has decreased from 5900 yuan/ton to 5790 yuan/ton, a decrease of 1.86%. The overall domestic mixed xylene market has declined this cycle, and the overall trend of the crude oil market has weakened during the week, dragging down the mentality of the spot market. This week, the Shandong region has been affected by low downstream purchasing intentions, resulting in continuous reductions in ex factory prices, attracting downstream buyers to enter the market for procurement and showing good trading enthusiasm. During the week, the supply in East and South China was relatively loose, with main refineries lowering their quotes and downstream demand being weak, resulting in an overall decline in market prices.

On the cost side: During this cycle, crude oil prices fluctuated mainly within a range. On the one hand, OPEC+announced a cumulative production increase of 2.3 million barrels per day until September, marking the organization’s exit from its plan to reduce production by over 2.2 million barrels per day one year ahead of schedule. This news is bearish for the oil market. On the other hand, the geopolitical situation in the Middle East is affecting the oil market, and global macro data is bearish. In addition, the fundamental impact of the upcoming off-season of US summer demand will continue to put pressure on the crude oil market price. As of August 14th, the settlement price of the US WTI crude oil futures September contract was reported at $63.96 per barrel. The settlement price of Brent crude oil futures for October contract is $66.84 per barrel.
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 August 15th, East China Company quoted 5850-5950 yuan/ton, North China Company quoted 5650-5850 yuan/ton, South China Company quoted 5800-5850 yuan/ton, and Central China Company quoted 5700-5800 yuan/ton.
On August 15th, Sinopec Sales Company temporarily stabilized the price of xylene, with the current execution price of 7000 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. The price remains unchanged from August 9th. As of August 14th, the closing prices of the xylene market in Asia were $799-801/ton FOB Korea and $824-826/ton CFR China, a decrease of $15/ton from August 8th.
Market forecast: In terms of supply, some equipment will be shut down for maintenance, but the production of equipment will remain high in the near future, and some manufacturers will start exporting. The market expects that the supply will still be relatively loose in the future. The demand for oil in the demand side adjustment industry is still acceptable in the near future, but the demand in the chemical industry is relatively weak. Overall, the supply and demand sides are still relatively weak, and it is expected that the xylene market will mainly operate steadily and weakly in the short term.

Shandong region was sluggish, and the price did not continue the downward trend of last week, but turned into a decline. According to the Commodity Market Analysis System of Shengyi Society, the main production area of Shandong experienced a weekly decline of 3.51%. The main reason for the increase in supply pressure is the gradual recovery of maintenance equipment in the early stage, coupled with weak local demand, resulting in a stock accumulation in the market. At present, the mainstream quotation in Shandong region is 2400-2500 yuan/ton.
Firstly, from the supply side perspective, the maintenance equipment in the main production areas of the north has been put into operation, resulting in a loose supply situation. Coupled with the increase in urea to ammonia conversion by manufacturers, the supply has significantly increased, and the rise in ammonia volume has dragged down ammonia prices. From the beginning of the week to the middle of the week, the prices of manufacturers have significantly loosened, but as the weekend approaches, the mentality of enterprises to raise prices is gradually strengthening. Some large factories have made slight price increases, but the magnitude is very limited. As of Friday, mainstream large factories in Shandong have generally lowered their prices by more than 100-200 yuan/ton. Distributors mainly underreport shipments.

Secondly, from the demand side, the operating rate of compound fertilizers is sluggish, with some downstream facilities in Shandong, Jiangsu, and Anhui undergoing maintenance, resulting in a decrease in operating rates and a decrease in ammonia consumption. 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.
Prediction: The market demand will be relatively light in the near future, with agricultural and industrial demand following closely. There will be little change in supply in the future, with equipment on and off, and overall showing a slow increasing trend. On the demand side, in the short term, the output of compound fertilizer is not high, but there is a possibility of a rebound in operating rate. In the future, the increase in supply and the rebound in demand will continue to pull. The price remains within a volatile range.

According to the Commodity Market Analysis System of Shengyi Society, the price of acetic acid in July first fell and then rose. As of July 30th, the price was 2400 yuan/ton, a decrease of 90 yuan/ton compared to the beginning of the month’s acetic acid price of 2490 yuan/ton, a decrease of 3.61%.

The price of acetic acid in July was mainly weak. In the first half of the year, the utilization rate of acetic acid production capacity on the supply side remained high, market inventory continued to accumulate, and there was significant pressure on enterprises to ship. The demand side and downstream market were weak, with excessive consumption of inventory as the main factor. The demand for acetic acid was limited, and the market supply-demand contradiction was obvious. Acetic acid prices continued to decline. The policy news in the latter half of the month boosted the shipment of enterprises, but downstream demand was limited, inventory pressure still existed, and the rise of acetic acid was hindered. Under the game of supply and demand, acetic acid overall declined during the month.
The methanol market on the raw material side is weak and volatile. As of July 30th, the average price in the domestic market was 2416.67 yuan/ton, a decrease of 4.48% compared to the beginning of the month price of 2530.00 yuan/ton. In the first half of the year, methanol prices continued to decline, and the market was constrained by weak terminal demand. The port methanol market accumulated inventory, and downstream methanol in mainland China maintained cautious procurement for essential needs, resulting in insufficient upward momentum in the methanol market; In the latter half of the year, boosted by macroeconomic policies, the methanol market showed a strong upward trend. However, due to weak traditional downstream demand, the market was suppressed, and the spot price of methanol fell again.
Market forecast: Business analysts believe that the acetic acid market is currently experiencing a partial downward trend, with supply pressure still present. Downstream demand support is average, and enterprise shipments are limited, resulting in weak short-term prices. In August, there will be maintenance plans for enterprises on the supply side. Under the supply-demand game, it is expected that the acetic acid market will fluctuate and consolidate in the later stage, and specific attention will be paid to downstream follow-up situations.
