1、 Price trend

According to the Commodity Market Analysis System of Shengyi Society, the aniline market has maintained stable operation this week. On October 20th, the market price of aniline was 7935 yuan/ton, and on October 24th it was 7995 yuan/ton, with no increase during the week and a decrease of 18.31% compared to the same period last year.
2、 Analysis and Review
This week, suppliers in the aniline market have raised prices, and prices have remained firm. As of this Friday, the mainstream price of aniline in the market is 7950-8050 yuan/ton. Mainstream factories have increased their workload this week, and maintenance equipment is preparing to restart, resulting in insufficient support from the supply side. Downstream demand remains high as raw materials continue to weaken. Under the influence of multiple factors, the aniline market is in a state of stagnation and consolidation.
Cost wise: The main port of pure benzene in East China maintains a pace of destocking, and the market sentiment is weak. Combined with weak downstream growth and intensified losses, coupled with insufficient new orders at the terminal, secondary downstream inventory remains high and difficult to reduce, resulting in significant resistance to price transmission. The pure benzene market continues to weaken and decline.
3、 Future expectations
The current favorable supply side of the aniline market has been exhausted, coupled with weak demand and weak cost side, it is expected that the aniline market will be prone to decline but difficult to rise in the future.

In the past half month, the price of polyester bottle chips has shown a trend of first suppressing and then stabilizing. In the early stage, it fell due to the drag of costs and demand, and in the later stage, with the increase of production rate and supply, the price fluctuated at a low level.

In early October, the overall performance of the polyester bottle chip market was weak, with prices fluctuating downwards. According to data from Shengyi Society, on October 10th, the market price in East China closed at 5812 yuan/ton, a decrease of about 40 yuan/ton compared to before the holiday. Subsequently, prices continued to run at a low level. On October 14th, polyester bottle chip factories lowered their quotes by 20-50 yuan. As of October 16th, the market price of polyester bottle chips has increased due to the influence of raw materials. Overall, the price of polyester bottle chips has remained stable after fluctuating and falling in the past half month.
Significant weakening of cost support
The ceasefire agreement reached between Palestine and Israel has eased the geopolitical situation, and international oil prices have fallen. The PTA and ethylene glycol markets, which are direct raw materials for polyester bottle chips, have also shown weakness, causing polyester bottle chips to lose important cost support, which is an important factor in the price decline.
From the perspective of the industrial chain, the absolute price of bottle flakes mainly follows cost fluctuations. Against the backdrop of the collective weakening of upstream raw materials, it is inevitable that the price of bottle chips will fall accordingly.
Supply pressure persists
Although mainstream factories have taken joint production cuts since the middle of the year, and the industry’s capacity utilization rate has remained at 73.37% recently, the market’s spot supply is still sufficient.
In addition, overcapacity is a long-term pressure faced by the industry, which continues to suppress the rebound space of prices.
Weak performance on the demand side
From January to August 2025, the production of soft drinks decreased by 4.8% year-on-year. In October, the weather turned cooler, and the demand for soft drinks and catering declined narrowly. The demand side lacked support for bottle tablets, and downstream end users’ procurement strategies mainly focused on cautious follow-up according to demand, lacking enthusiasm for large-scale stocking, resulting in a shift in the market transaction center.
Overall, Business Society believes that the polyester bottle chip market is expected to continue its weak and volatile pattern in the short term.
