According to the monitoring of the commodity market analysis system of Shengyi Society, the average price of LLDPE (7042) was 7453 yuan/ton on August 1st and 7441 yuan/ton on August 11th, a decrease of 0.16%. LDPE (2426H) had an average price of 9516 yuan/ton on August 1st and 9533 yuan/ton on August 11th, an increase of 0.18%. HDPE (2426H) had an average price of 7975 yuan/ton on August 1st and 7987 yuan/ton on August 11th, an increase of 0.16%.
Since August, polyethylene has fluctuated with narrow range operations. The favorable domestic policies provide certain support for the polyethylene market. The pre maintenance equipment on the supply side has been restarted one after another, and there are expectations of an increase on the supply side. On the demand side, in early August, the downstream is in a low season of demand with limited new orders. The market is cautious and lacks support. In late August, the downstream will prepare in advance for the peak season, and there is a positive expectation on the demand side. Due to market concerns that the new round of US tariffs will drag down the global economy, oil prices fell sharply last week, suppressing the polyethylene market.
Loose supply, positive expectations on the demand side, and policy support are expected to lead to narrow range fluctuations in polyethylene.

According to the Commodity Market Analysis System of Shengyi Society, from August 4th to 8th, the domestic aggregated MDI market saw a slight increase, with an average price of 15650 yuan/ton at the beginning of the week and 15800 yuan/ton at the end of the week. The increase during the period was 0.96%, and the year-on-year decrease was 9.37%. During the week, the factory started operating steadily, and news of price increases was released. Intermediary quotes remained stable and pushed up, while downstream transactions were small and single occupancy was high. Under the supply-demand game, the market saw a slight increase.
On the supply side, the maintenance of the 80000 ton/year MDI plant in Dongcao Rui’an will begin on July 23rd and is expected to last for about 35 days.
In terms of cost, the recent fluctuations in raw materials such as pure benzene and aniline have limited impact on the polymerization of MDI.
On the demand side, downstream demand is average, the trading atmosphere is quiet, and transactions are mainly small orders.
In the future forecast, the current aggregated MDI market is supported by the willingness of suppliers to raise prices, and prices are tentatively pushed up. In the short term, there is little change in the supply and demand side, and it is expected that the resistance to the continued rise of the aggregated MDI market in the short term will increase, and the market will continue to consolidate and operate.

According to the Commodity Market Analysis System of Shengyi Society, the mixed xylene market has slightly increased this week, rising from 6010 yuan/ton to 6070 yuan/ton from July 28 to August 4, 2025, an increase of 1%. The domestic mixed xylene market overall closed higher this cycle, with petrochemical plant maintenance in Shandong region. The supply in the region is tight, and refineries have generally raised their ex factory prices. The port inventory in East and South China is relatively low, and downstream market enthusiasm is still acceptable, resulting in a slight increase in market prices.
Cost wise: As of August 1st, international crude oil futures closed down, with the settlement price of the September WTI crude oil futures contract in the United States at $67.33 per barrel. The settlement price of Brent crude oil futures for October contract is $69.67 per barrel. The market is concerned that OPEC may increase oil production, coupled with US employment data dragging down the demand outlook.
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 4th, East China Company quoted 6150 yuan/ton, North China Company quoted 5750-5950 yuan/ton, South China Company quoted 6150-6200 yuan/ton, and Central China Company quoted 5800-6050 yuan/ton.
Demand side:
On August 4th, 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 has been reduced by 250 yuan/ton compared to July 28th. As of August 1st, the closing prices of the xylene market in Asia were $834-836/ton FOB Korea and $859-861/ton CFR China, a decrease of $13/ton from July 25th.
Market forecast: In terms of supply, the recent arrival situation in Hong Kong is not good, and the market supply is tight, which will provide a certain boost to the market in the short term. From the demand side, the downstream chemical and oil blending industries are performing well, and there are some purchasing intentions in the oil blending industry. Supported by favorable supply side conditions, it is expected that the market will rebound slightly in the short term, but the overall upward space is limited.

The overall focus of the domestic acetone market declined in July, with a slight increase at the end of the month. The acetone market in East China reported an average daily price of 5000 yuan/ton from July 1st to 4850 yuan/ton on July 30th, a decrease of 3%. From the perspective of the national acetone market, there are fluctuations of the same magnitude.
In the first half of the month, raw material products fluctuated, and the driving force from the cost side weakened. Phenol ketone factories continued to be in a loss making state, with significant shipping pressure. At the beginning of the month, the acetone market rapidly fell, with a low of 4600 yuan/ton in the East China region. Petrochemical companies followed the market fluctuations and overall lowered their listing prices.
In the middle of the month, with the normal operation of the Yangzhou Shiyou plant, the industry operating rate of the phenol ketone factory exceeded 80%, and the market supply was sufficient. The pressure on traders increased, but the market was close to a low level and the downward space was limited. With downstream inquiries on dips, factories urgently need to follow up on purchases, and market trading volume has increased. In the latter half of the month, Hengli Petrochemical’s phenol ketone unit was shut down for maintenance, causing the industry’s operating rate to decline by 5%. Although supply is still sufficient, due to limited replenishment at the port, inventory has fallen to 20000 tons. Traders intend to boost the market and offer tentative increases, with a daily increase of 20-30 yuan/ton in the last week of the month.
The acetone offers in major mainstream markets across the country on July 31st are as follows:
Region. Quotation on July 31st /Price fluctuations in July
East China region./4800-4850./-200
Shandong region / 5000./ -350
Yanshan region / 4900./ -400
South China region / 4950./ -100
In July, the 320000 tons/year phenol ketone plant at Yangzhou Shiyou was shut down for maintenance from June 13th to July 10th; Hengli Petrochemical will shut down for maintenance from July 21st to 27th; Guangxi Huayi will stop for maintenance from July 25th to 27th; The Shanghai Xisa plant stopped briefly on July 28th for a 3-day maintenance.
It is expected that the market may experience a slight increase in August. From the supply side, the Zhenhai Refining and Chemical Phenol Ketone Plant has been shipped normally, and the domestic supply of acetone has increased. From the perspective of imports, Saudi Arabia’s facilities have been shut down for maintenance, Middle Eastern sources are limited, and Thailand’s facilities have maintenance plans. Currently, the import volume has slightly decreased. 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 external environment remains weak, and pure benzene is also an important factor in the later fluctuations of acetone. 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 in August.

According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province has fallen and fluctuated overall, with an average market price of 17250 yuan/ton at the end of the month and 16175 yuan/ton at the beginning of the month, a monthly increase of 6.65%.
This month’s market analysis
Starting from July, magnesium prices have remained stable and rebounded, with a stalemate game and a slight decline in prices. The mid month magnesium market showed a trend of first decreasing and then stabilizing, with significantly increased resistance to price decline and a return to stability. At the end of the month, the magnesium market showed strong upward momentum, with prices starting a moderate upward trend and continuing to climb. As the end of the month approaches, magnesium prices remain stable at a high level.
Supply and demand side
On the supply side, due to the advantage of small spot inventory, factories continue to maintain a willingness to raise prices, and low-priced goods are extremely scarce in the market. Affected by extreme high temperatures, magnesium smelting enterprises are facing numerous difficulties in resuming work and production, while production costs have also increased to a certain extent. Holders of low-priced goods in the market are generally reluctant to sell, and this strong sentiment has led to a rapid shift in market supply and demand from the previous loose situation to a tight state, further enhancing the driving force for price increases and driving prices to continue rising.
On the demand side, although downstream demand shows some signs of improvement, a cautious procurement pace is still maintained, and downstream customers and intermediaries mainly carry out small-scale replenishment operations based on rigid demand. Enterprises in the mid month application field have shown a high acceptance of current prices, however, some trading enterprises have a strong willingness to lower prices due to accepting orders at lower prices in the early stage. With the concentrated release of demand for magnesium in industries such as new energy vehicles and two wheeled electric vehicle components, the market demand scale is rapidly expanding. In addition, influenced by the prevalent consumer psychology of “buying up, not buying down” in the market, the purchasing enthusiasm of application end enterprises and traders has been fully ignited, thus forming a strong upward force on magnesium prices from the demand side, injecting momentum into the rise of magnesium prices.
In terms of raw materials
Coal, ferrosilicon, and other essential raw materials for magnesium smelting have seen their prices continue to rise, creating a stable bottom line for magnesium prices and becoming important supporting factors for their upward trend.
Future forecast
The current market supply and demand sides are in a stalemate, and given the recent high magnesium prices, low-priced sources are extremely scarce in the market. The downstream buyers have a cautious mentality, and although there have been inquiries, the actual transaction volume is at a relatively low level. Due to multiple factors such as the recent rise in raw material prices, supply side contraction, and reduced spot supply, there is limited room for concessions in actual order negotiations. Overall, magnesium prices are unlikely to rise or fall in the short term, and are expected to remain stable.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market saw a significant upward trend in July. As of July 30th, the spot rubber market in China was around 15070 yuan/ton, an increase of 7.67% from 13996 yuan/ton at the beginning of the month.
At the beginning of the month, downstream demand was weak, and there was sufficient supply of natural rubber raw materials both domestically and internationally, resulting in a narrow consolidation of the natural rubber market. Starting from mid month, on the one hand, domestic production areas have entered a period of reduced production and cutting, and on the other hand, the geopolitical conflict between Thailand and Cambodia has intensified, jointly driving up the price of natural rubber significantly; At the end of the month, the conflict between Thailand and Cambodia cooled down, and the natural rubber raw material market slightly fell. As of July 30th, the mainstream price for 24 years of Guangken, Baodao, and Haibao latex in Qingdao area is 14900~15300 yuan/ton.
The price of natural rubber raw materials fell sharply in July. As of July 30th, the price of Thai glue was 55.00 baht/kg, a decrease of 1.79% compared to 56.00 baht/kg at the end of June. Currently, domestic production areas are entering a period of reduced production and cutting, while overseas main production areas are still in the peak season for rubber production. Coupled with the cooling of geopolitical conflicts in Southeast Asia, expectations for the price of natural rubber raw materials are expected to decrease in the short term.
The natural rubber inventory continued to increase slightly in July, which had a bearish impact on the natural rubber market. As of July 27, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 640400 tons, an increase of 1.31% from 632100 tons at the end of June.
Downstream tire production slightly increased in July, with domestic tire companies’ semi steel tire production slightly rising from 7.00% at the beginning of the month to around 7.50% at the end of the month; The construction of all steel tires by tire companies in Shandong has increased from 6.20% to around 6.50% by the end of the month. Mainly for natural rubber rigid support..
Market forecast: When domestic and international raw material prices stabilize at high levels and are expected to decline, downstream tires will support the demand for natural rubber, and Tianjin Rubber Port inventory will remain high; Overall, it is expected that the natural rubber market will fluctuate at a high level in the later stage.

According to the Commodity Market Analysis System of Shengyi Society, the domestic aggregated MDI market first fell and then rose in July, with an overall decline. From July 1st to 29th, the domestic market price of aggregated MDI increased from 15500 yuan/ton to 15483 yuan/ton, with a monthly price drop of 0.11% and a year-on-year price drop of 12.11%.
In early July, except for the maintenance of Wanhua Fujian plant, the northern large factory reduced its load and operated smoothly, while other plants operated steadily and the supply of goods was stable. Downstream demand is sluggish, with small orders being the main focus, leading to a lack of confidence among industry players and a continuous decline in aggregated MDI.
In mid to late July, after the continuous decline of aggregated MDI, the supply side tentatively pushed up, and the low price converged. The price rose to around 15500 yuan/ton, making it difficult to transact at high prices. Under the supply-demand game, the aggregated MDI market began to consolidate and operate horizontally.
Supply side, Shanghai installation maintenance completed. Restart gradually. The 80000 ton/year MDI plant in Dongcao Rui’an will begin maintenance on July 23rd and is expected to last for about 35 days. Hungary’s 400000 tons/year MDI will be gradually shut down for maintenance starting from July 23rd, with an expected maintenance period of about 30 days.
On the cost side, raw material pure benzene: The pure benzene market fluctuated within a range in July, with overall prices slightly rising compared to the beginning of the month. The average price at the beginning of the month is 5942 yuan/ton, and the average price at the end of the month is 5988 yuan/ton, with a monthly increase of 0.75%. Raw material aniline: The aniline market fluctuated and fell in July. On July 1st, the market price of aniline was 7900 yuan/ton, and on July 29th it was 7375 yuan/ton, a decrease of 6.65% during the month.
On the demand side, downstream urgent procurement, entering the market at low prices. There are few inquiries and insufficient support from the demand side.
Market forecast: As the end of the month approaches, the market atmosphere will become weaker, intermediaries’ willingness to ship is weak, and the supply side’s willingness to raise prices will increase. We are waiting for the latest price guidance from major manufacturers, and it is expected that the aggregated MDI market will consolidate and operate in the short term.

1、 Price trend
According to the commodity analysis system of Shengyi Society, caustic soda has been running steadily this week. On July 28th, the average market price in Shandong was 861 yuan/ton, an increase of 6.69% compared to last year. On July 27th, the Business Social Chemical Index was 771 points, unchanged from yesterday, a decrease of 44.93% from the highest point of 1400 points during the cycle (October 23, 2021), and an increase of 28.93% from the lowest point of 598 points on April 8, 2020. (Note: The cycle refers to the period from December 1, 2011 to present)
2、 Market analysis
According to the commodity analysis system of Shengyi Society, the price of caustic soda is operating steadily. The price of caustic soda in Shandong region is around 790-880 yuan/ton in the mainstream market of 32% ion-exchange membrane alkali. The price of caustic soda in Jiangsu region is stable, with a mainstream market price of 870-930 yuan/ton in 32% ion-exchange membrane alkali. The price of caustic soda in Inner Mongolia region is stable, with a mainstream market price of 2700-2800 yuan/ton (converted to 100%) in 32% ion-exchange membrane alkali. From the perspective of Shandong region, there is not much fluctuation in supply and demand, and most enterprises are still executing preliminary orders. The demand side increment is limited, and alumina is mostly purchased on demand, while non aluminum receiving is mainly purchased on demand.
Business analysts believe that in the near future, the price of caustic soda has been operating steadily, and the domestic downstream demand has been average. The price of caustic soda is maintaining a stable operation. With the price increase, the downstream market is resistant to the comprehensive expectation that caustic soda will maintain a stable operation in the later period, depending on the downstream market demand.

According to the Commodity Market Analysis System of Shengyi Society, from July 21st to 25th, the average price of BDO in China fell from 8721 yuan/ton to 8685 yuan/ton, with a price drop of 0.41% during the period, a month on month drop of 0.16%, and a year-on-year drop of 3.49%. The domestic supply of BDO has increased. However, the main downstream industries have experienced a decline in production, and the amount of raw materials digested continues to decrease. The contradiction between supply and demand has intensified, and traders are holding a selling and shipping mentality, dragging the market center of gravity down continuously.
On the supply side, the industry’s supply continues to increase, but there is no positive support from the supply side. BDO supply and sales are affected by negative factors.
On the cost side, raw material calcium carbide: the domestic calcium carbide market is stable with small fluctuations. The unstable market operation has led to a reduction in supply, but the temporary recovery of demand has accelerated the consumption of waiting vehicles in the market. Raw material methanol: The domestic methanol market has rebounded, and as of 10:00 am on July 25th, the reference price for domestic methanol in Taicang is 2500 yuan/ton. The fluctuation and consolidation of raw materials such as calcium carbide and methanol have a mixed impact on the cost of BDO.
On the demand side, the downstream PTMEG, GBL-NMP, PBAT industries have seen a decrease in load, while PBT, TPU and other industries have seen an increase in production. However, the overall production on the demand side has declined, leading to a continued reduction in raw material digestion and exacerbating the imbalance between supply and demand structure in the industry. In addition, under the traditional off-season effect, terminal demand is light, and under the pressure of supply and demand, some downstream industries such as THF, PBT, GBL-NMP, and spandex have seen a decline in market prices, resulting in a compression of profit margins and severe pressure on raw material prices. The demand side of BDO is affected by bearish factors.
The future forecast shows that supply will still be significantly higher than demand, and the imbalance between supply and demand will intensify. Moreover, downstream industries are experiencing losses, resulting in severe pressure on raw material prices. The market lacks favorable support. Business analyst BDO predicts that the domestic BDO market may continue to weaken.

1、 Price trend
According to the Commodity Market Analysis System of Shengyi Society, as of July 24th, the reference average price of domestic urea market was 1832 yuan/ton, which is 0.41% higher than the reference average price of 1825 yuan/ton on July 17th.
2、 Market analysis
market conditions
This week, the domestic urea market price first rose and then fell. At the beginning of this week, downstream purchasing intentions improved, and the trading atmosphere in the urea market increased. Manufacturers are mainly raising prices, and the domestic urea market prices are rising. Starting from Wednesday, the futures market began to cool down, and with the urea market still dominated by oversupply, urea prices began to decline. As of July 24th, the urea market prices in Shandong are around 1790-1830 yuan/ton, Hebei is around 1790 yuan/ton, Henan is around 1780-1830 yuan/ton, Hubei is around 1800 yuan/ton, and Liaoning is around 1780 yuan/ton.
Supply and demand situation
On the supply side, some companies underwent equipment maintenance this week, resulting in a decrease in daily production, but the urea market supply remains abundant. In terms of demand, there has been an improvement in the autumn fertilizer preparation situation. Compound fertilizer manufacturers replenish as needed, increasing demand for raw material procurement.
3、 Future forecast
Business Society’s urea analyst believes that the domestic urea market has been weak and declining recently. Manufacturers are mainly pushing prices, but market inventory remains high, coupled with poor futures market trends. It is expected that in the short term, the domestic urea price will be weak and mainly operated through consolidation.
