price trend
According to the bulk ranking data of Shengyi Society, the domestic PC market has been stable with small fluctuations recently, and some spot prices of certain brands have been raised narrowly at low levels. As of June 17th, the mixed benchmark price of Business Society PC is around 14500 yuan/ton, with a price fluctuation of -0.75% compared to early June.
cause analysis
On the supply side: In mid June, the load of domestic PC aggregation enterprises continued to rebound. The average operating level of the industry has increased by 3% to 85% compared to the first ten days, and the weekly average production has increased to over 68000 tons. In the future, there will be a technical upgrade task for the equipment in the latter half of the year, and it is expected to be shut down for one month. However, the production loss is limited, and there have been few recent arrangements to reduce negative loads. In addition, PC inventory has remained high for a long time, and the on-site supply is very abundant. Manufacturers and midstream inventory levels remain high, with no reduction in shipping pressure, and there has been no improvement in the market supply side’s support for PC prices.
In terms of raw materials, it can be seen from the above chart that bisphenol A continued its weak trend in mid June. Although the strong upstream crude oil market in the far end has driven the recovery of PC direct raw materials acetone and phenol, the transmission of positive news to PC still needs a process. On the other hand, due to the increased workload of the PC industry in the early stage, the on-site supply of goods has increased. However, downstream demand is sluggish. Overall, the supply-demand imbalance of bisphenol A remains unchanged, and its support for PC costs continues to weaken.
On the demand side: With the gradual warming of the domestic climate, the downstream factories of PC are experiencing a decrease in load, and stocking is mainly due to weak demand, gradually entering the traditional off-season for consumption, further dragging down the PC consumer end. Due to the long-term weak market dynamics in the industry, high social inventory, and abundant supply of goods in the market, the supply-demand contradiction in mid June did not improve, but rather showed a profound impact. At present, terminal enterprises are cautious in purchasing new orders, and their trading performance continues to be dominated by contract delivery. Merchants tend to have a wait-and-see attitude, buyers are resistant to high priced goods, and the flow of goods in the market is slow. Overall, the demand side has weak support for PC spot prices.
Future forecast
In June, the domestic PC market in China was consolidating at a low level. The upstream bisphenol A market continues to decline, providing poor support for the cost value of PC. The load of domestic PC aggregation plants continues to rise, and the pattern of strong supply is even more severe. However, downstream demand is at a low season level, and industry players remain pessimistic about the future market. At the same time, the industry’s inventory is high, and the seller camp is willing to sell and sell at a discount. At present, the market is only favorable in the upstream sector, and it is expected that the PC market will continue to consolidate weakly in the future.

Under the strong support of cost, the price center of polyester staple fiber increased in June. According to the Commodity Market Analysis System of Shengyi Society, as of June 16th, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6646 yuan/ton, an increase of 2.07% from the beginning of the month.
The international crude oil market has experienced a surge in prices due to the escalation of the conflict between Iran and Israel, escalating regional tensions, and heightened concerns about oil supply disruptions. As of June 13th, the settlement price of the July WTI crude oil futures contract in the United States was $72.98 per barrel, and the settlement price of the August Brent crude oil futures contract was $74.23 per barrel.
The domestic PTA spot market followed the rise of crude oil, with the average PTA market price in East China at 5008 yuan/ton as of June 16th, an increase of 0.86% from the beginning of the month. But mainstream domestic producers have restarted their facilities, and Honggang Petrochemical’s 2.5 million ton annual production facility has been put into operation, resulting in a significant increase in supply and an industry operating rate of around 83%. The peak of PTA plant maintenance has passed, and new production capacity is being tested and put into operation to curb PTA growth.
The performance of domestic and foreign trade orders at the terminal is scarce, with a small number of orders being mainly sampled in autumn and winter. There is still uncertainty about future orders, and the recovery speed is significantly slower than expected. The weaving operation rate is still at a low level, and there may be downward risks in the weaving industry at the end of the month. Therefore, the inventory of short fibers has once again accumulated to a certain extent, and prices still face significant pressure.
Business analysts believe that international oil prices will continue to rise in the short term, but the restart of PX and PTA maintenance facilities, coupled with the production of new facilities, will increase supply. In addition, with the arrival of the seasonal off-season at the terminal, demand performance is weak, and there is an expectation of weakened supply and demand. It is expected that the price of polyester staple fiber will remain volatile and warm in the short term.

This week (June 9-13, 2025), the market situation for the main raw material of viscose staple fiber, dissolved pulp, has slightly improved, with some support from raw material inventory. The on-site equipment is operating well, and downstream cotton yarn enterprises are just in need of purchasing, with average delivery speed and continued weak demand without improvement. As a result, the market price of viscose staple fiber has declined slightly.
According to the Commodity Market Analysis System of Shengyi Society, as of June 13th, the average market price of viscose staple fiber was 13160 yuan/ton, a decrease of 200 yuan/ton from the same period last week, with a weekly decline of 1.50%.
In terms of cost: This week (June 9-13, 2025), there was little change in the market price of raw material dissolution slurry, a slight rebound in the market price of auxiliary liquid alkali, a large stability and small fluctuation in the market price of sulfuric acid, and some support in the average production cost of adhesive short fibers.
Supply demand: The operating rate of adhesive short fiber manufacturers’ equipment remained stable within the week, and the industry supply remained stable. The downstream cotton yarn market has a strong wait-and-see atmosphere, with prices being mainly deadlocked. Insufficient orders have been placed in the terminal market, and downstream yarn companies still have a certain amount of raw material inventory. Coupled with high finished product inventory, a small number of orders are mainly signed on demand, resulting in average delivery speed and weak demand without improvement.
Future forecast
On the raw material side, the main material dissolution slurry market may operate weakly and steadily, the auxiliary material liquid alkali market may have an upward trend, and the sulfuric acid market or the overall market remains stable. Therefore, it is expected that the market price trend of adhesive short fiber raw materials will be inconsistent next week, and the cost support will be average.
Supply and demand side: The operating rate of the adhesive short fiber market equipment may not fluctuate significantly, and some manufacturers have high inventory levels. Therefore, it is expected that the supply side support of the adhesive short fiber market will be poor in the short term; Downstream yarn factories mainly consume raw material inventory and have a weak willingness to replenish raw materials. They may maintain rigid procurement, making it difficult for the demand side to improve. Therefore, it is expected that the demand side of the adhesive short fiber market will perform poorly next week.
Overall, the main raw material dissolution slurry market may experience weak consolidation, and downstream yarn market procurement enthusiasm is difficult to improve. The expected trading atmosphere in the market is flat. Business analysts predict that the domestic adhesive short fiber market will remain stable with small movements next week, and prices are expected to be accepted at 12800-13200 yuan/ton.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has fluctuated slightly higher in recent times (6.1~6.11). As of June 11th, the spot rubber market price in China’s natural rubber market was around 13758 yuan/ton, an increase of 3.38% from 13308 yuan/ton on the 1st. On the one hand, there has been some good news supporting the recent trade negotiations between China and the United States, and the macroeconomic outlook has slightly improved, which has boosted the Shanghai rubber market. On the other hand, although downstream tire production has slightly decreased, it still maintains a relatively high level, providing some essential support for rubber. Promote a slight increase in natural rubber prices recently. As of June 11th, the mainstream price for 23 years of Guangken, Baodao, and Haibao latex in Qingdao area ranges from 13700 to 14000 yuan/ton. However, judging from the prices of natural rubber raw materials and port inventory, there is still some pressure on the natural rubber market.
As of June 11th, the price of Thai glue was 56.50 baht/kg, a decrease of 7.75% from 61.25 baht/kg at the end of May. The rubber cutting operation in Thailand, an overseas rubber production area, has begun, and the prices of cup and glue have loosened slightly. In addition, the Yunnan production area in China has entered the cutting process. Although the recent increase in precipitation in Thailand and Hainan has led to a slight rebound in raw material prices in recent days, the expectation of global supply increase in the later stage remains unchanged, and the price of natural rubber raw materials is expected to continue to decline.
Recently (6.1~6.11), natural rubber inventories have slightly decreased but still remain high, which has a bearish impact on the natural rubber market. As of June 8, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 605500 tons, a decrease of 4100 tons or 0.67% compared to the previous period.
The recent (6.1~6.11) slight decline in downstream tire production has provided essential support for the natural rubber market. As of June 8th, the operating load of semi steel tires in domestic tire enterprises is around 7.3%; The operating load of all steel tires in tire enterprises in Shandong region is about 6.3%. As of the week of June 8th, domestic tire companies had 42 days of finished steel tire inventory, which remained unchanged on a week on week basis; The inventory of semi-finished steel tires remained unchanged on a week on week basis for 46 days.
Market forecast: As domestic and international raw material prices stabilize at high levels and expectations continue to decline in the later stage, downstream production will slightly decrease, weakening support for natural rubber. In addition, the inventory of Tianjiao Port is still at a high level; Overall, it is expected that the natural rubber market will consolidate weakly in the later stage.

Last week (June 2-8, 2025), the upstream cost support of nylon filament was insufficient, downstream enterprises had poor procurement efforts, and the fundamentals were weak. Downstream manufacturers held onto rigid demand procurement in multiple aspects, and the mainstream focus of the nylon fiber market did not change significantly, resulting in weak and stable prices.
Nylon filament prices remain weak and stable
According to the Commodity Market Analysis System of Shengyi Society, the price of nylon filament remained weakly stable last week (June 2-8, 2025). As of June 8, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14760 yuan/ton, unchanged from the previous week’s price; Nylon POY (premium product; 86D/24F) quoted 12300 yuan/ton, unchanged from the previous week’s price; The price of nylon FDY (premium product: 40D/12F) is reported at 15400 yuan/ton, which is the same as the previous week’s price.
The raw material market remains weak and stable
In terms of cost: Last week (June 2-8, 2025), the spot market price of caprolactam remained weak and stable, and some manufacturers in the PA6 slice market had a good transaction atmosphere, but the cost was relatively weak. As of June 8, 2025, the benchmark price of caprolactam in Shengyi Society is 9450 yuan/ton, and the price is stable. During the week, the market price of high-speed spun nylon PA6 slices slightly decreased, with a weekly drop of 0.63%, mainly due to weak cost support.
Supply and demand: During the week, some nylon filament manufacturers have lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continue to increase, leading to poor performance on the supply side; The demand in the end market is weak, and some downstream manufacturers have reduced production or switched production, resulting in a decrease in demand for nylon filament. It is difficult to find favorable support from the demand side.
Future forecast
Cost aspect: In terms of caprolactam, pure benzene is expected to be weak, and the supply of caprolactam may recover next month. Slice manufacturers have low enthusiasm for purchasing caprolactam, and it is expected that the caprolactam market will continue to decline next week; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the market price of nylon PA6 slicing will decline.
Supply and demand: June is a transitional period from the market to the traditional off-season, coupled with the lack of signs of improvement in terminal market demand and low purchasing enthusiasm in downstream markets. Therefore, it is expected that the demand for nylon filament market may decrease next month. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.
Overall, both the upstream raw material caprolactam spot market and the nylon PA6 chip market are likely to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down market trends, and under the dual negative factors, analysts from Shengyi Society predict that the short-term nylon filament market prices will continue to be weak, with a decline expected to be between 100-300 yuan/ton.
