According to the Commodity Market Analysis System of Shengyi Society, the domestic polyester staple fiber market has stopped its downward trend and stabilized since early April. As of April 21, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6317 yuan/ton, an increase of 0.71% from April 9.
The raw material market is intertwined with bullish and bearish factors in crude oil. Based on the subsequent impact of current US tariff policies, crude oil may enter a new cycle in the long run. The supply-demand balance will be disrupted, and in the process of rebalancing, crude oil prices will fluctuate and adjust in the short term. As of April 18th, the settlement price of the main contract for WTI crude oil futures in the United States was $63.98 per barrel, and the settlement price of the main contract for Brent crude oil futures was $67.26 per barrel.
During the maintenance of PX facilities both domestically and internationally, the domestic PX load has decreased to 73%. In the maintenance of Yangzi, Jiujiang, and Zhejiang Petrochemicals, Hainan Refinery and Pengzhou Petrochemicals have reduced their load and improved their supply. However, under the tariff war, costs and demand are greatly affected, and the overall situation is relatively weak. PTA is undergoing planned maintenance, and the industry’s operating rate is currently around 75%. In terms of prices, the downward trend has slowed down significantly. As of April 21, the average price in East China was 4330 yuan/ton, a decrease of 0.19% from April 11.
Downstream performance is weak, demand uncertainty is high under the tariff war, inventory pressure is high, and cash flow surges and falls. The shipping pace of yarn factories is average, and some enterprises’ inventory levels continue to rise, so the expectations for pre holiday stocking are not optimistic. There is currently no sign of improvement in the terminal weaving market, with insufficient follow-up on new orders and a strong wait-and-see atmosphere. The probability of Jiangsu and Zhejiang weaving remains around 63%.
Business analysts believe that the short-term cost support range is mainly fluctuating, and the tariff policy continues to suppress the export of terminal textiles. The demand mentality is pessimistic, and there are concerns about the decline in the operating rate of terminal weaving machines and the lack of clear direction guidance for polyester short fibers. In the short term, it may maintain a wide range of fluctuations.

This week (April 14-18, 2025), the center of gravity of raw material prices has fallen again, and the market price of nylon filament has followed suit. Sinopec’s high-end caprolactam price was lowered to 10080 yuan/ton last week, and the high-speed spinning market for nylon PA6 chips continued to decline, with weak cost support; During the week, the operating load of some nylon filament manufacturers’ facilities decreased, resulting in a narrow decline in industry supply. Some manufacturers had high inventory levels, and the performance of the supply side was average; There are few orders in the terminal market, and some downstream manufacturers are reducing production and taking holidays. Other manufacturers are holding on to their essential needs, resulting in limited on-site transactions and a sluggish demand side. Overall, the upstream raw material market is weak and declining, with some on-site inventory levels at high levels. Downstream companies have average purchasing power, and negative factors in the market dominate. The price pressure on the nylon filament market continues to decline.
According to the Commodity Market Analysis System of Shengyi Society, the price of nylon filament continued to decline weakly this week (April 14-18, 2025). As of April 18, 2025, the price of nylon filament DTY (premium product; 70D/24F) in Jiangsu region is 15480 yuan/ton, a decrease of 100 yuan/ton from last week, a weekly decrease of 0.64%; Nylon POY (premium product; 86D/24F) is priced at 12900 yuan/ton, a decrease of 200 yuan/ton or 1.53% from last week’s price; The price of nylon FDY (premium product: 40D/12F) is reported at 16075 yuan/ton, a decrease of 150 yuan/ton from last week, with a weekly decline of 0.92%.
The raw material market is weak and declining
In terms of cost: Sinopec’s high-end caprolactam weekly closing price has been lowered. As of April 18, 2025, the benchmark price of caprolactam in Shengyi Society is 9660 yuan/ton, with a weekly decline of 5.45%. During the week, the market price of high-speed spun nylon PA6 chips fell sharply, with a 2.01% drop in nylon PA6 prices, indicating weak cost support.
Supply and demand: This week (April 14-18, 2025), the operating rate of the nylon filament market equipment did not fluctuate much, the industry supply was at a high level, some manufacturers had high inventory levels, downstream market demand was light, and some nylon filament prices were not smooth for shipment. Many were sold at discounted prices, and the overall profit situation of the market was still not optimistic.
Future forecast
Cost aspect: In terms of caprolactam, the trend of raw material pure benzene is average, and the supply of caprolactam market may recover to some extent. The purchasing enthusiasm of the demand side is not good, and it is expected that the market price of caprolactam will slightly decline next week. In terms of nylon PA6 slicing, there is insufficient cost support, and there is no significant improvement in terminal demand. Downstream manufacturers are cautious in purchasing for essential needs, and it is expected that the nylon PA6 slicing market will continue to decline next week. Therefore, it is expected that the price trend of the raw material market will decline next week.
Supply and demand side: Some manufacturers of nylon filament have high inventory, and there are plans to reduce the operating load of the equipment. There is a possibility of a decrease in on-site supply, and it is expected that the supply side of the nylon filament market will perform generally in the short term; Downstream domestic demand is limited, and there has been no significant improvement in foreign trade orders. Some downstream manufacturers have production reduction plans, and demand is expected to decrease. Therefore, it is expected that the driving force from the demand side of the nylon filament market will remain weak next week.
Overall, there are still downward expectations in the spot market for raw material caprolactam and the market for nylon PA6 chips, with weak cost support and no signs of improvement in downstream market demand. Industry players lack confidence in the future market, and Business Society analysis predicts that the price of nylon filament market will fall next week, with an expected decline of 100-300 yuan/ton.

The hydrofluoric acid market has been operating steadily this week. According to the analysis system of Shengyi Society, as of April 16th, the benchmark price of hydrofluoric acid in Shengyi Society was 12450 yuan/ton, an increase of 1.63% compared to the beginning of this month (12250 yuan/ton).
On the raw material side, the market for fluorite sulfuric acid, a raw material, is experiencing a weak decline, and the cost pressure on anhydrous hydrogen fluoride production enterprises has eased to some extent. According to the analysis system of Shengyi Society, as of April 16th, the benchmark price of Shengyi Society’s fluorite was 3731.25 yuan/ton, a decrease of -1.16% compared to the beginning of this month (3775.00 yuan/ton).
On the demand side: Downstream refrigerant domestic and foreign trade will usher in a peak demand season, with some enterprises producing at full capacity. Currently, market prices are still running at high levels, and the trading atmosphere is normal. Inventory pressure is gradually being released. The terminal sector has entered the peak production season, with increased demand supporting the continued high and firm price of anhydrous hydrogen fluoride.
Market forecast: In the near future, there will be a slight downward trend in the market price of raw material fluorite sulfuric acid. The cost pressure on anhydrous hydrogen fluoride production enterprises has eased, but it is expected that the decline in raw material prices will not be too large. The downstream refrigerant market is good, and the end demand has entered the production peak season. The demand side has certain support for the anhydrous hydrogen fluoride market. It is expected that the anhydrous hydrogen fluoride market will continue to operate at a high level in the future, and more attention should be paid to the news of leading enterprises and market supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, the rise in the PP market in the first half of April was hindered, and the prices of most brand products fell back. As of April 16th, the mainstream offer price for wire drawing by domestic producers and traders is around 7565 yuan/ton, with an increase or decrease of+0.02% compared to the price level at the beginning of April.
price trend
In terms of raw materials:
In the first half of April, the US tariff policy was implemented, with tariff rates constantly changing and increasing to unprecedented heights. The tariff trade war launched by Trump has had a huge impact on the global economy. Crude oil, as a heavily affected area, has experienced a sharp drop in prices recently. At the same time, it seriously affects the domestic supply of propane, and also drags down the operation and profitability of PDH manufacturing enterprises. The highest strength in the propylene field is insufficient, and it has entered a weak oscillation trend. Overall, the prices of various raw materials in the first half of April did not provide strong support for the cost of PP.
Supply side:
In the first half of April, domestic PP enterprises had a large and stable load with small fluctuations, and the market supply remained generally abundant. Overall, the current industry load level is around 79%, with an average weekly production of approximately 760000 tons in China. Recently, Guangdong Petrochemical, CNOOC Shell, and Ningbo Jinfa have successively implemented maintenance plans, resulting in an overall expansion of production capacity losses and an expected supply contraction in the future. There is an upward trend in the supply side’s support for PP spot prices.
In terms of demand:
In the first half of April, the demand for PP remained stable with some weakness, and on-site trading maintained a weak rigid demand pattern. In terms of plastic weaving, the consumption level of terminal enterprises has generally stabilized. The demand for PP in fields such as architecture and agriculture is gradually increasing with the warming of temperatures. However, under the influence of international news such as equivalent tariffs imposed by the United States, the global economy has been greatly impacted and future uncertainty has increased. Although the domestic PP import and export dependence share is relatively small, its downstream product exports are hindered. Buyers tend to maintain production through scattered small orders in their purchasing operations, although there has not been a significant increase in new orders in the market. Overall, the demand side of PP weakened in the first half of April.
Future forecast
In the first half of April, the domestic PP market prices fluctuated weakly. From a fundamental perspective, the overall performance of upstream raw materials in supporting PP is average, with abundant industry supply and weak demand support in consumption. The future industry market pattern is characterized by a 1:2 bearish guidance formed by weak supply search and consumption, as well as weakened costs. There is a clear avoidance of suspicion within the market. In the short term, the price trend may not see a significant increase, and it is recommended to closely monitor the situation of tariffs and the circulation of goods.

After some factories raised their listing prices yesterday, Sinopec North China’s listing price increased by 100 to 6000 yuan/ton today, Yangzhou Shiyou’s listing price increased by 100 to 6000 yuan/ton, and Fuyu Petrochemical’s acetone price increased by 5900 yuan/ton.
