Report Industry Investment Rating - The report expects PX, PTA, and PR to run strongly, with a view score of 1 for each [2] Core Viewpoints - International crude oil has risen to a seven - week high, and it is predicted that PX, PTA, and PR will run strongly [2] Summary by Related Catalogs Price Information - On September 24, 2025, the futures settlement price of WTI crude oil was $64.99 per barrel, up 2.49% from the previous value; Brent crude oil was $69.31 per barrel, up 2.48% [1] - The spot price of naphtha (CFR Japan) was $606 per ton, up 1.42%; the spot price of xylene (isomeric grade, FOB Korea) was $672 per ton, up 2.05% [1] - The spot price of PX (CFR China Main Port) was $812 per ton, up 0.95%; the closing price of CZCE TA main contract was 4,626 yuan per ton, up 1.54% [1] - The CCFEI price index of PTA inner - market was 4,520 yuan per ton, up 1.16%; the outer - market was $600 per ton, down 1.48% [1] - The closing price of CZCE PX main contract was 6,602 yuan per ton, up 1.10%; the closing price of CZCE PR main contract was 5,784 yuan per ton, up 1.15% [1] - The CCFEI price index of polyester bottle - grade chips was 5,750 yuan per ton, up 0.70%; the CCFEI price index of polyester chips was 5,725 yuan per ton, up 0.26% [2] Supply and Demand and Market Conditions - An 700,000 - ton PX plant in Northeast China has been under maintenance since September 18, expected to last about 45 days [2] - Geopolitical risks have increased, and overnight crude oil rebounded after a short adjustment. The cost - end oil market rebounded slightly, driving up PX cost momentum. However, there are still concerns about the domestic PX fundamentals, and the monthly spread is small [2] - The increase in PX supply due to short - process capacity increase and postponed maintenance is obvious, while the demand for PX has decreased more than expected due to the delay of new PTA plant commissioning and multiple PTA maintenance. The PX profit will remain low in the short term [2] - The cost support for PTA has recovered slightly. The typhoon has affected the operation of a PTA plant in Zhuhai, which is temporarily beneficial to the PTA market. But the end - of - month shipment pressure of production enterprises is large, and the polyester product sales are flat [2] - The polyester bottle - chip market has a warm - oscillating trend in terms of raw materials and futures. The supply - side quotation has risen, but the downstream terminal trading has weakened, and the trading atmosphere is light. Some bottle - chip plants have shut down briefly due to the typhoon, with limited impact on market supply [2] Production and Sales and Operating Rates - On September 24, 2025, the operating rate of the PX in the polyester industry chain was 85.57%, unchanged; the PTA plant load rate was 78.12%, down 1.26 percentage points; the polyester plant load rate was 87.73%, down 1.27 percentage points [1] - The sales rate of polyester filament was 80.65%, up 41.74 percentage points; the sales rate of polyester staple fiber was 67.04%, up 18.96 percentage points; the sales rate of polyester chips was 143.48%, up 85.45 percentage points [1]

Report Industry Investment Rating - No information provided in the given text Core View of the Report - The report predicts that PX, PTA, and PR will operate in a volatile manner in the short - term [2] Summary by Relevant Catalogs Price Information - **Upstream**: On September 25, 2025, WTI crude oil futures settlement price was $64.98 per barrel, down 0.02% from the previous value; Brent crude oil futures settlement price was $69.42 per barrel, up 0.16%.

The closing price of the near - month contract was 4,640 yuan per ton, up 1.18%; the settlement price was 4,630 yuan per ton, up 1.58%. The domestic PTA spot price was 4,597 yuan per ton, up 0.81%. The CCFEI price index of domestic PTA was 4,585 yuan per ton, up 1.44%; the external price index was $609.00 per ton, up 1.50% [1] - **PX**: On September 25, 2025, the closing price of CZCE PX's main contract was 6,674 yuan per ton, up 1.09%; the settlement price was 6,640 yuan per ton, up 1.10%. The closing price of the near - month contract was 6,678 yuan per ton, up 0.69%; the settlement price was 6,470 yuan per ton, down 2.03%. The domestic PX spot price remained unchanged at 6,382 yuan per ton. The spot price (CFR China Taiwan) was $813.00 per ton, up 1.12%; the spot price (FOB South Korea) was $796.00 per ton, up 1.02%. The PXN spread was $208.50 per ton, up 1.05%; the PX - MX spread was $141.00 per ton, up 0.84% [1] - **PR**: On September 25, 2025, the closing price of CZCE PR's main contract was 5,840 yuan per ton, up 0.97%; the settlement price was 5,816 yuan per ton, up 1.04%. The closing price of the near - month contract was 5,874 yuan per ton, up 1.31%; the settlement price was 5,856 yuan per ton, up 1.00%.

The expected pressure of supply glut has not been reflected in the market, and oil prices were stagnant during the Asian session. The CFR China price of PX on September 25 was $817 per ton, and international oil prices continued to rise due to the decline in US crude oil inventories. The domestic PX operating load was stable, and the demand side was waiting for the implementation of the expected changes in PTA plants. The cost support led to a slight price recovery. The PX2511 contract closed at 6,674 yuan per ton (up 1.61%), with a trading volume of 185,500 lots. The increase in PX supply due to the increase in short - process production at home and abroad and the postponement of some plant maintenance was obvious, while the demand for PX decreased more than expected due to the delay of new PTA plant commissioning and multiple PTA plant maintenance. The supply - demand situation did not change significantly, and the PX profit would remain low in the short term [2] - **PTA**: The cost support slightly recovered, and the TA2601 contract closed at 4,678 yuan per ton (up 1.74%), with a trading volume of 701,000 lots. The sales of polyester filament on Wednesday evening were around 149% and 175% on Thursday, which was positive for the PTA market. The cost support was strengthened, and there was a strong expectation of PTA plant maintenance due to low processing fees. The leading polyester factories adjusted the production rhythm to stabilize market supply, but the production enterprises faced great pressure to sell at the end of the month. The new orders of weaving enterprises improved, and the shipment speed of grey cloth continued to improve, but the overall inventory pressure in the grey cloth market still existed, leading to the lack of confidence of downstream enterprises in the future market. As the National Day holiday approached, the sentiment in the downstream market was clearly divided, and some enterprises expected the market to improve after the holiday [2] - **PR**: The mainstream negotiation price of polyester bottle chips in the Jiangsu - Zhejiang market was 5,800 - 5,900 yuan per ton, up 55 yuan per ton from the previous trading day. The prices of PTA and bottle - chip futures rose, and the supply - side quotation of bottle chips mainly increased, but the purchasing enthusiasm of downstream terminals was not high, and the trading atmosphere was light. The PR2511 contract closed at 5,840 yuan per ton (up 1.46%), with a trading volume of 28,600 lots. The operating rate of the bottle - chip industry was expected to gradually recover, and the market supply of goods was relatively abundant. The purchasing intention of downstream terminals was not high, and the market trading atmosphere was light [2] Production and Sales and Operating Conditions - **Operating Conditions**: On September 25, 2025, the operating rate of the PX in the polyester industry chain was 85.57%, unchanged from the previous value; the load rate of PTA plants in the PTA industry chain was 78.12%, unchanged; the load rate of polyester plants was 87.81%, up 0.08 percentage points; the load rate of bottle - chip plants was 69.37%, up 0.27 percentage points; the load rate of Jiangsu - Zhejiang looms was 69.19%, up 1.64 percentage points [1] - **Production and Sales**: On September 25, 2025, the sales rate of polyester filament was 175.16%, up 94.51 percentage points from the previous value; the sales rate of polyester staple fiber was 88.58%, up 21.54 percentage points; the sales rate of polyester chips was 152.51%, up 9.03 percentage points [1]

Investment Rating - The report gives an "Overweight" rating for the chemical industry [1] Core Viewpoints - The supply side is expected to undergo structural optimization, with a focus on selecting elastic and advantageous sectors. Domestic policies frequently emphasize supply-side requirements, while rising raw material costs and capacity exits in Europe and the U.S. have impacted overseas chemical companies. In the long term, China's chemical industry has a clear competitive advantage, with significant cost benefits and technological advancements, allowing Chinese companies to fill gaps in the international supply chain [6][16] Summary by Sections 1. Industry News and Event Commentary - Prices of third-generation refrigerants continue to rise, indicating a high level of industry prosperity. The supply of refrigerants is constrained by quotas, and increased downstream demand has significantly optimized the supply-demand balance. Prices for R32, R134a, and R125 have increased by 44.19%, 22.35%, and 8.33% respectively this year. Major refrigerant producers have seen substantial profit growth, with companies like Juhua Co., Sanmei Co., and Yonghe Co. reporting net profit increases of 145.84%, 159.22%, and 140.82% year-on-year in the first half of 2025 [15][8] 2.

Important News and Market Analysis - **PX**: On September 17, due to Ukraine's harassment of Baltic ports, Russia's weekly crude oil exports plummeted, and the overall positive impact on the crude oil supply - demand situation was limited. The cost support for PX was insufficient. The domestic PX operating load was at a high level, and some device maintenance plans were postponed. The demand - side PTA factory maintenance expectations increased, and there was only one transaction heard during the day. The supply of PX increased, and although it was the peak season for downstream polyester, the new orders and load did not exceed expectations, and the PXN was expected to operate weakly [2]. - **PTA**: The fundamentals did not change significantly. The influence of the Fed's interest - rate cut was overdrawn, the crude oil market declined during the session, the sales of polyester filament were flat, and the PTA market increase was limited. The supply of PTA was expected to increase in the short term, and the new PTA device maintenance plans from October to November had limited impact on the current market [2]. - **PR**: The mainstream negotiation price of polyester bottle - chips in the Jiangsu and Zhejiang markets decreased.
