According to the Commodity Market Analysis System of Shengyi Society, the overall price of polyester filament in August showed a trend of recovery. The market is affected by factors such as cost and supply and demand. As of August 29th, the mainstream polyester filament factories in Jiangsu and Zhejiang Province quoted POY (150D/48F) at 6800-6950 yuan/ton, polyester DTY (150D/48F low elasticity) at 8000-8150 yuan/ton, and polyester FDY (150D/96F) at 7000-7200 yuan/ton.

The specific trend is as follows:
Rising in early August: The price of polyester filament increased slightly in early August. On August 12th, some polyester factories raised the price of FDY and other specifications by 50-100 yuan/ton. FDY production and sales significantly rebounded over the weekend, with local POY production and sales rates as high as 700%.
Mid month decline: Prices fell in mid August. As of August 15th, the mainstream polyester filament factories in Jiangsu and Zhejiang, POY (150D/48F), quoted at 6600-6900 yuan/ton, polyester DTY (150D/48F low elasticity) at 7800-8050 yuan/ton, and polyester FDY (150D/96F) at 7000-7200 yuan/ton. As of August 23rd, POY prices range from 7400-7600 yuan/ton, DTY prices range from 9000-9200 yuan/ton, and FDY prices range from 8000-8200 yuan/ton.
In late August, prices rose again. On August 26th, major polyester filament manufacturers raised their prices one after another, with DTY rising by 50 yuan, some specifications rising by 100 yuan, and some factories directly reporting a price increase of 200 yuan/ton.
Cost side: At the beginning of the month, due to lower than expected demand and US economic data, polyester raw materials were weak, PX hit a new low since its listing, PTA fell below the long-term support level of 5500 yuan/ton, and the cost side support was insufficient, leading to a decline in polyester filament prices. On August 15th, international crude oil futures rose, driving PX prices to rise synchronously, and the cost was transmitted to PTA, which gave a certain boost to the price of polyester filament. The expectation of the US Federal Reserve to cut interest rates in the next ten days and the Russia-Ukraine conflict and other factors led to a sharp rise in crude oil and the rise in the cost of polyester raw materials, driving up the price of polyester filaments.
Supply side: Polyester factories maintain a high operating rate of over 90%, but leading enterprises regulate the market through centralized production cuts. Coupled with limited new production capacity in August, the supply pressure is temporarily relieved, which provides some support for prices.
On the demand side: Terminal textile orders have not yet substantially rebounded, and weaving enterprises have high inventory of raw fabrics. The traditional off-season ends in mid to late August, and procurement is mainly based on essential needs. However, as the “Golden September and Silver October” approaches, there is a certain demand for stockpiling downstream. Since late August, there has been an increase in domestic and foreign trade orders, and the operating rate of downstream weaving factories has gradually rebounded to around 60%, which has driven the price of polyester filament. Manufacturers, in order to repair their profit margins, create expectations of price increases through continuous price hikes, forcing downstream customers to passively purchase goods. Downstream and end customers have cautious expectations for the future, with a clear wait-and-see attitude. However, during the process of price increases, they may also buy at low prices, causing market prices to fluctuate.

Business Society believes that cost support is expected to remain strong, coupled with traditional peak season demand expectations and the willingness of enterprises to raise prices, these factors may continue to drive prices upward. It is expected that there is a high possibility of strong fluctuations in the price of polyester filament in the short term.

According to the Commodity Market Analysis System of Shengyi Society, as of August 28th, the reference average price of the domestic urea market was 1717 yuan/ton, a decrease of 5.24% from the reference average price of 1812 yuan/ton on August 1st.
2、 Market analysis
Supply and demand situation
The domestic urea market has been weak and declining this month. In the first half of this month, the domestic urea market prices mainly declined. The urea futures market price has fallen, and the spot market has followed the weakening trend of the futures market. The urea market has sufficient supply but relatively weak demand. In mid month, the domestic urea market price slightly increased. Market inventory remains high, and futures prices are rising. At the end of this month, the domestic urea market prices rapidly declined. The futures market is not performing well, and the agricultural demand for urea in autumn has entered the off-season. The trading atmosphere in the urea market has weakened, with a small amount of downstream purchases and no significant improvement in demand.
market situation
As of August 28th, the urea market prices in Shandong are around 1680-1720 yuan/ton, Hebei is around 1690-1730 yuan/ton, Henan is around 1660-1720 yuan/ton, and Liaoning is around 1740 yuan/ton.
According to the weekly K-bar chart from June 2, 2024 to August 18, 2025, it can be seen that the domestic urea cycle is characterized by ups and downs. Domestic urea fell significantly in August, with the largest drop being -1.1% in the week of August 4th.
3、 Future forecast
Business Society’s urea analyst believes that the urea market has rebounded slightly after a continuous decline in recent days. At present, the supply of urea in the market is still at a high level, the demand for agriculture is weakening, and downstream demand is mainly replenished, resulting in low purchasing enthusiasm. It is expected that the domestic urea market will experience a weak consolidation and operation in the short term.

1、 Price trend

According to the Commodity Market Analysis System of Shengyi Society, the average price of ammonium sulfate in the domestic market was 1086 yuan/ton on August 27th, and 1140 yuan/ton on August 1st. This month, the market price of ammonium sulfate has dropped by 4.68%.
2、 Market analysis
The ammonium sulfate market has declined this month. This month, the supply of ammonium sulfate market is sufficient, downstream inquiries have decreased, procurement enthusiasm has weakened, and the market transaction atmosphere is light. The export market is not performing well, with pressure on enterprise shipments and a sluggish ammonium sulfate market. As of August 27th, the mainstream ex factory quotation for coking grade ammonium sulfate in Shandong region is around 1000 yuan/ton. Domestic grade ammonium sulfate, the mainstream ex factory quotation in Shandong region is around 1025-1080 yuan/ton.
According to the weekly K-bar chart from June 2, 2025 to August 18, 2025, it can be seen that the domestic ammonium sulfate cycle is fluctuating. The domestic price of ammonium sulfate fell significantly in August, with the largest drop being 1.11% in the week of August 11th.
3、 Future forecast
An ammonium sulfate analyst from Shengyi Society believes that the price of ammonium sulfate in China has been stable but declining recently. At present, the atmosphere of inquiries in the ammonium sulfate market has weakened, and market transactions are poor. There has been no improvement in domestic and international demand, and downstream wait-and-see sentiment has increased. It is expected that the domestic ammonium sulfate market will be weak in the short term, mainly due to consolidation and operation.

At the end of August, the overall ABS market continued to be weak, with some grades experiencing a decline in spot prices. According to the Commodity Market Analysis System of Shengyi Society, as of August 26th, the average price of ABS sample products was 10150 yuan/ton, with a price level increase or decrease of -1.58% compared to early August.

Fundamental analysis
Supply level: Since August, the domestic ABS industry has seen an increase in load before leveling off. The Dalian plant restarted in the first half of the month, and the Tianjin equipment pipeline blowing task ended. At the end of the month, the equipment dynamics were limited, and the overall industry load level remained at 71% of mid month. The weekly average output was around 140000 tons, which remained stable. The inventory level of aggregation enterprises increased at a high level of 230000 tons, and the supply on site remained abundant. Overall, the long-term loose supply pattern in the ABS market remains unchanged, and the high inventory levels in the industry are relatively controllable. But Zhenjiang Qimei and Liaoning Jinfa have heard that there is a plan to increase the load, and the supply side is expected to continue to be loose. Therefore, the supply side has weak support for ABS spot prices.
Cost factor: At the end of August, the ABS upstream three material market had a relatively narrow change, which had limited impact on the cost side support of ABS. Acrylonitrile is operating in a stalemate within the interval, and Zhejiang Petrochemical has increased production, resulting in an increase in on-site supply. The main force in consumption lies in contract delivery, while spot market trading is sluggish, leading to increased pressure on local inventory. Combined with the decline in the raw material propylene market, it is expected that acrylonitrile may continue to remain weakly stable in the short term.
The domestic butadiene market fluctuated slightly at the end of August. In mid month, the Fushun petrochemical plant underwent maintenance, and at the same time, after a period of digestion of port cargo, low-priced spot goods in the market decreased, and the atmosphere of the spot market began to improve. On the other hand, the rise in downstream rubber futures has boosted the market, and positive news is transmitted upwards. The overall performance of the butadiene market is biased towards positive, with a narrow range of price increases.
Recently, there has been a narrow rebound in styrene. In terms of raw material pure benzene, downstream procurement is coming to an end at the end of the month, and the pressure on middlemen to ship has increased, resulting in a downward trend in transaction volume and average support for styrene. At present, the production profit of styrene is still acceptable, and the supply remains high due to high production. However, high port inventory limits the rise of styrene. Without significant changes on a macro level, it is expected that the styrene market will experience weak fluctuations in the short term.
On the demand side: In the medium to long term, the downstream factories of ABS have had average loads. The current market is in a period of transition between peak and off peak seasons, and terminal enterprises have not seen any improvement in procurement. The logic is still to maintain the demand for supplementary orders. In mid August, the production schedule of the electrical casing industry further decreased and consumption shrank. Without significant changes on a macro level, the cautious atmosphere in the external market remains unchanged, and the flow rate of goods is slow. Domestic inventory levels remain high and sideways, with continued loose supply and ample room for on-site turnover. Overall, there has been no improvement in the demand side’s support for the ABS market.
Future forecast
At the end of August, the domestic ABS market was weakly consolidating. The overall changes in the upstream three materials are not significant, while the production load of the ABS polymerization plant remains flat, and the demand side’s off-season level remains unchanged. Analysts from Shengyi Society believe that the long-term drag on spot prices of ABS due to supply and demand contradictions makes it difficult for the market momentum to improve. It is expected that the ABS market will maintain a weak and stable consolidation trend in the short term.

According to the Commodity Market Analysis System of Shengyi Society, as of August 25th, the average quotation price of domestic high-quality DMF enterprises was 4110 yuan/ton, which remained stable compared to the same period last week. Currently, the price fluctuation range of DMF manufacturers is limited, and the focus of DMF market negotiations is stable, with a general purchasing atmosphere.
2、 Cause analysis
Market wise: DMF spot delivery price reference in the South China region: 4250-4350 yuan/ton in the Guangzhou market, with a stable focus. DMF bulk delivery price reference in the East China region: 4100-4300 yuan/ton in Jiangsu and 4150-4350 yuan/ton in Zhejiang. DMF bulk delivery price reference in the Shandong and North China markets: 3950-4150 yuan/ton.
Upstream: The market price of methanol in Xuzhou is based on the factory withdrawal of 2310-2320 yuan/ton, with a focus on contract execution in the early stage and market observation. The transaction price of domestically produced methanol in Changzhou is based on 2330 yuan/ton, and the market price of methanol in Xuzhou is based on the factory withdrawal of 2310-2320 yuan/ton. The contract execution in the early stage is mainly based on market observation.
3、 Future forecast
DMF analysts from Shengyi Society believe that the DMF market is expected to maintain its current trend in the short term, with insufficient upstream cost support, weak downstream demand, and limited price upward momentum.

2、 Market analysis
This week, the price of bromine has remained strong, with a reference price of 28000-31000 yuan/ton for spot bromine production in Shandong region. Due to weather and policy reasons, bromine companies are facing tight inventory, and downstream companies are mainly in urgent need. In terms of raw materials, domestic sulfur prices have been rising, with an average market price of 2604.33 yuan/ton at the beginning of the week and 2617.67 yuan/ton over the weekend. The price has increased by 0.51%, which is 81.78% higher than the same period last year. Downstream demand is still acceptable.
Prediction: Bromine prices are expected to remain strong in the near future, with upstream sulfur prices rising. Bromine prices are expected to improve this week, while downstream demand is expected to increase. Overall market activity is moderate. It is expected that bromine will continue to consolidate and operate in the later period, depending on downstream market demand.

According to the Commodity Market Analysis System of Shengyi Society, from August 13th to 20th, the domestic ethanol price fell to 5575 yuan/ton, with a price drop of 1.33% during the period, a month on month drop of 2.19%, and a year-on-year drop of 6.81%. The domestic ethanol market prices are running weakly, and factories have a positive attitude towards shipment, resulting in a decrease in quotations.

In terms of cost, the overall decline in corn prices is the main factor. The futures market has fallen, and market sentiment has changed. Port traders have lowered their quotes by 20-30 yuan, and the speed of port pickup is average. The downstream procurement mentality is cautious, and the overall focus is on consuming inventory. The cost of ethanol is influenced by bearish factors.
On the supply side, there is little fluctuation in the production of edible ethanol. The impact of ethanol supply is mixed.
On the demand side, from the demand side, the downstream Baijiu and chemical end have entered the traditional off-season, the demand for some chemical exports has improved, and the consumer side is expected to narrow down. Negative factors affecting ethanol demand.
The future forecast shows that the supply side will continue to increase, and the price of ethanol will be under pressure from the supply-demand game, with a mainly oscillating downward trend. The ethanol analyst from Shengyi Society predicts that the short-term ethanol market will mainly operate weakly.

According to the commodity analysis system of Shengyi Society, the price trend of soda ash continued to decline this week. As of August 18th, the average market price of soda ash was 1224 yuan/ton, a decrease of 28 yuan/ton compared to the price of 1252 yuan/ton on August 11th, a decrease of 2.24%.
2、 Market analysis
Recently, the soda ash market has been operating weakly. The number of supply side maintenance enterprises has decreased, the production of soda ash has increased, and manufacturers are actively shipping; The downstream demand performance is mediocre. Due to the continued weakness of glass prices, the market’s enthusiasm for purchasing soda ash is not high, and soda ash enterprises have accumulated inventory. The market supply is strong and demand is weak, and soda ash prices continue to decline. On August 18th, the price of light soda ash in East China was reduced by 10 yuan/ton, with a price range of 1130-1400 yuan/ton; The price of light soda ash in central China remains at 1140-1300 yuan/ton.

The glass market has stable production capacity, continuous inventory increase, average downstream demand follow-up, slow glass destocking, poor enterprise shipments, and a weak downward trend in glass prices.
Future forecast: Currently, the price trend of soda ash is downward, and the mentality of industry players is bearish. In terms of inventory, manufacturers have limited shipments and accumulated inventory. The downstream market is weak, and there is insufficient support for soda ash. It is expected that the soda ash market will mainly operate weakly in the later stage, and specific attention will be paid to downstream follow-up situations.
