1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For PX, last week, PXN oscillated downward. The main reasons were the postponement of PX maintenance plans, numerous unexpected maintenance of downstream PTA under low processing fees, and the delay of new device commissioning. The overall load was low, making it difficult for PX to reduce inventory. With weak terminal performance, PXN lacked the momentum to expand. Currently, PX load remains high, while downstream PTA has many unexpected short - term maintenance, with a low overall load center. The expected delay of new PTA device commissioning and PX maintenance is expected to continue the PX inventory accumulation cycle. The valuation is currently at a moderately low level. It is recommended to wait and see in the short term [11]. - Regarding PTA, last week, PXN continued to be weak, PTA processing fees rebounded, and the overall price slightly decreased. The valuation was slightly repaired, but the upward space was relatively limited. On one hand, the terminal performance continued to be weaker than expected. On the other hand, even though PTA continued to reduce inventory through maintenance, the long - term outlook was still weak under the commissioning pressure. In the future, the unexpected maintenance volume on the supply side remains high, and the inventory reduction pattern will continue. However, due to the weak long - term pattern, the processing fee space is limited. On the demand side, the inventory and profit pressure of polyester and chemical fiber are low, and the load is expected to remain high. But the weak terminal performance exerts pressure on raw materials. In terms of valuation, PXN is continuously affected by the weak terminal performance and the continuous unexpected maintenance of PTA under low processing fees. The upward valuation needs to be driven by the improvement of the terminal or the maintenance of raw materials. It is recommended to wait and see in the short term [12]. - Concerning MEG, the industrial fundamentals show that the load of domestic and overseas devices is at a high level, and the domestic supply is high. But in the short term, due to the low port arrival volume, the port inventory is expected to be low. In the medium term, as imports arrive in a concentrated manner and the domestic load is expected to remain high, coupled with the gradual commissioning of new devices, the inventory will increase in the fourth quarter. The current valuation is relatively high year - on - year. It is recommended to short - allocate on rallies under the weak outlook, but beware of the risk that the weak expectation may not be realized [13]. 3. Summary According to the Directory 3.1.

The US clothing wholesale inventory was lower than the pre - pandemic high, and the inventory increased marginally [211][219][223].

Report Industry Investment Rating - No relevant information provided Core Viewpoints - The PTA market is affected by the decline in crude oil prices, weakening cost support. With the restart of domestic PTA devices, PTA output is rising, and the basis is rapidly declining. The OPEC+ meeting increased oil production again. Downstream profits have significantly recovered, and the polyester operating load has rebounded to 91%. [2] - The ethylene glycol basis is weakening. The upcoming commissioning of Yulong Petrochemical's ethylene glycol device is putting pressure on the market. Although the arrival of overseas ethylene glycol devices has decreased, the hedging volume has increased after the price recovery. Polyester inventory is in good condition, and the downstream weaving load has rebounded. [2] Summary by Directory Market Data - **Crude Oil**: INE crude oil price dropped from 489.2 yuan/barrel on September 11, 2025, to 475.3 yuan/barrel on September 12, 2025, a decrease of 13.9 yuan/barrel [2]. - **PTA**: PTA主力期价 decreased from 4688 yuan/ton to 4648 yuan/ton, and the spot price dropped from 4620 yuan/ton to 4575 yuan/ton.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - PTA is expected to continue its weak oscillatory pattern in the short - term. Although the cost side provides some support and there is a mild recovery during the "Golden September and Silver October" season, with an expected increase in domestic supply, the balance sheet may shift from destocking to stockpiling. Also, the processing fee is at a low level [6]. - MEG is expected to operate weakly in the short - term. It is in a destocking cycle, but the total supply is expected to increase due to new device commissioning, and the demand side shows a slow increase in polyester load. Attention should be paid to the lower support level [6]. 3. Summary According to the Table of Contents 3.1 Upstream Industry Chain Analysis - **Market Review**: Geopolitical instability supports oil prices, but OPEC+ may increase production in October, and demand has a seasonal decline. Thus, international oil prices are expected to face pressure next week. PX supply - demand is weak due to the previous unexpected shutdown of downstream PTA devices. As of September 12, the Asian PX closing price was $831.33 per ton CFR China, up $1.33 per ton from September 5 [16]. - **PX Capacity Utilization**: There was no device change this week, and production was stable. The domestic PX weekly average capacity utilization was 84.63%, with a 0% week - on - week change. The Asian PX weekly average capacity utilization was 74.71%, up 0.27% week - on - week [19]. - **PX - Naphtha Price Spread**: As of September 12, the PX - naphtha price spread was $232.8 per ton, down $0.92 per ton from September 5. With the increase in downstream PTA operating rate, PX is entering a destocking phase, and the PX - naphtha price spread is expected to rebound [22]. 3.2 PTA Fundamental Analysis - **Market Review**: With the restart of previously overhauled PTA devices and mediocre terminal orders during the traditional peak season, the PTA balance sheet is still destocking. However, due to overall poor commodity performance and concerns about future supply increases, PTA oscillated narrowly this week. As of September 12, the PTA spot price was 4,565 yuan per ton, and the spot basis was 2601 - 79 [25]. - **Capacity Utilization**: The weekly average PTA capacity utilization reached 74.95%, up 4.30% week - on - week and down 6.33% year - on - year. The restart of previously overhauled devices led to an increase in capacity utilization. In September, with the planned and expected restart of multiple devices, the domestic PTA device capacity utilization is expected to reach around 78% [28]. - **Processing Fee**: The PTA processing fee has weakened again due to increased domestic supply and slow terminal recovery. However, with a low valuation, the further downward space is limited, and it is expected to continue its weak pattern in the short - term [30]. - **Supply - Demand in September**: In September, with insufficient PTA device overhauls and the restart of overhauled devices, and little change in demand, PTA supply - demand is expected to shift from destocking to a loose balance [33]. 3.3 MEG Fundamental Analysis - **Market Trend**: The supply - demand structure of ethylene glycol has no obvious change, and the main port inventory has reached a new low this year. However, due to new capacity commissioning and high domestic operating rates, the price decline has widened, once breaking through the 4,400 - yuan integer mark. As of September 12, the closing price of ethylene glycol in Zhangjiagang was 4,378 yuan per ton, and the delivered price in the South China market was 4,460 yuan per ton [38]. - **Domestic Production**: The total ethylene glycol capacity utilization was 66.55%, down 0.90% week - on - week. The integrated device capacity utilization was 66.92%, up 0.09% week - on - week, and the coal - based ethylene glycol capacity utilization was 65.96%, down 2.47% week - on - week. In September, with the restart of some domestic existing devices and the end of the overhaul season, the overall ethylene glycol production is expected to continue to rise [42]. - **Port Inventory**: As of September 18, 2025, the total expected arrival volume of ethylene glycol in East China was 11.28 tons. As of September 11, the total port inventory of MEG in the East China main port area was 36.32 tons, down 2.36 tons from September 8 and 1.31 tons from September 4 [43]. - **Processing Profit**: With the ethylene glycol main port inventory remaining at a low level, but new device commissioning and a pessimistic supply outlook, the ethylene glycol price declined this week. With raw material prices showing different trends, the sample profits of each ethylene glycol process showed both increases and decreases. As of September 12, the profit of naphtha - based ethylene glycol was - $102.41 per ton, down $3.99 per ton from last week, and the profit of coal - based ethylene glycol was - 53.39 yuan per ton, up 3.31 yuan per ton from last week [48]. 3.4 Downstream Demand Analysis of the Industry Chain - **Polyester Production**: The weekly average polyester capacity utilization was 87.9%, up 0.56% week - on - week. There is no clear expected change in polyester device supply next week, and domestic polyester production is expected to remain stable [51]. - **Capacity Utilization Expectation**: In August, the polyester operating rate fluctuated narrowly. In September, due to the expectation of the traditional peak season, the planned restart of some previously reduced - production and overhauled devices, and the expected commissioning of multiple new devices, the monthly polyester load is expected to increase [54]. - **Capacity Utilization of Polyester Filament**: This week, the weekly average capacity utilization of polyester filament was 91.43%, up 0.15% from the previous period. The average capacity utilization of polyester staple fiber was stable at 86.82%, up 0.37% week - on - week. The capacity utilization of fiber - grade polyester chips was 81.99%, up 1.57% week - on - week [57]. - **Product Inventory**: Downstream procurement is cautious, and the overall sales level is average. The finished product inventory of polyester filament factories has slightly accumulated this week [60]. - **Cash Flow of Polyester Products**: With the decrease in polymerization cost, the transaction center of polyester products has also decreased, but the decline is smaller than that of raw materials, resulting in a partial repair of cash flow [62]. - **Weaving Load**: As of September 11, the comprehensive operating rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 62.42%, the same as the previous data. The average terminal weaving order days were 14.55 days, an increase of 0.66 days from last week. Order recovery is less than expected, and the weaving load is expected to remain stable [67]. 3.5 Summary of Polyester Industry Chain Fundamentals - **Cost Side**: Geopolitical instability supports oil prices, but OPEC+ may increase production in October, and demand has a seasonal decline. International oil prices are expected to face pressure next week. PX supply - demand is weak due to the previous unexpected shutdown of downstream PTA devices [68]. - **Supply Side**: PTA capacity utilization has increased this week. MEG total capacity utilization has decreased slightly, with a slight increase in integrated device capacity utilization and a decrease in coal - based capacity utilization [68]. - **Demand Side**: Polyester capacity utilization has increased, and the chemical fiber weaving operating rate in the Jiangsu and Zhejiang regions has remained the same. Order recovery is less than expected, and the overall market is in a wait - and - see state [68]. - **Inventory**: PTA has a strong expectation of future supply - demand stockpiling. MEG port inventory in the East China main port area has decreased [68].

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The recovery speed of the terminal market is slow, and the upstream valuation is difficult to expand. PX, PTA, and MEG markets have different supply - demand and inventory situations. PX and MEG are expected to have inventory accumulation, while PTA is expected to continue de - stocking. The polyester end is gradually warming up, but the terminal performance is still poor. Attention should be paid to the follow - up performance of terminal orders and the opportunities of going long on dips following the raw materials during the peak season [11][12][13] Summary by Directory 1. Monthly Assessment and Strategy Recommendation - **PX**: Last month, the price first declined with crude oil and then increased due to unexpected production cuts in the raw material end. However, the actual unexpected maintenance volume was lower than expected, and the terminal performance was weak, suppressing the raw material valuation. Currently, the PX load remains high, and the downstream PTA has many unexpected short - term maintenance, with a low overall load center. But due to the commissioning of new PTA devices, the inventory accumulation range of PX is not large. The terminal and polyester data are gradually improving, and the valuation has limited downside space. However, due to the lack of driving force, PXN has limited upward momentum. The current valuation is at a moderately low level, and attention should be paid to the opportunity of going long on dips following crude oil during the peak season [11] - **PTA**: Last month, the processing fee first increased after unexpected maintenance and then was compressed again. PXN was weak due to inventory accumulation, and crude oil fluctuated downward, causing the PTA price to rise and then fall. In the future, the unexpected maintenance volume on the supply side has increased, and the inventory accumulation pattern has changed to de - stocking. However, due to the non - implementation of some maintenance, the processing fee is suppressed. On the demand side, the inventory pressure of polyester and chemical fiber is low, and the downstream and terminal operations have improved, but the terminal recovery speed is slow. In terms of valuation, PXN has limited downside space under the improved pattern brought by PTA commissioning, and the raw material end valuations are all at low levels. Attention should be paid to the opportunity of going long on dips following PX after the terminal performance improves during the peak season [12] - **MEG**: Last month, the port inventory continued to decline, providing strong support for the overall valuation. However, the valuation weakened with the news of new device commissioning plans. In terms of industry fundamentals, the maintenance devices at home and abroad have gradually started, and the operation rate has reached a high level, with a high domestic supply. However, due to the low port arrival volume in the short term, the port inventory is expected to be low. In the medium term, with the concentrated arrival of imports and the expected continuous high domestic load, the inventory will turn to accumulation in the fourth quarter. The current valuation is relatively high year - on - year, and the low short - term arrival volume supports the valuation, but there is downward pressure on the medium - term valuation [13] 2. Futures and Spot Markets - **PX**: The basis fluctuated weakly, and the spread strengthened. The open interest and trading volume of active contracts and total contracts are presented in relevant charts [32][39][42] - **PTA**: The basis gradually weakened, and the spread was weak. The open interest and trading volume of active contracts and total contracts are shown in relevant charts [45][51][54] - **MEG**: The basis first declined and then strengthened, and the spread fluctuated weakly. The open interest was at a low level, and the trading volume decreased. The open interest and trading volume of active contracts and total contracts are presented in relevant charts [57][63][66][69] - **Overseas Commodity Prices**: The overseas prices of PX, MEG, and PTA FOB China are shown in relevant charts [71][72] 3. Para - Xylene (PX) Fundamentals - **Capacity**: New capacity is expected to be added in 2025, such as the 300 - ton new capacity of Yantai Yulongdao [76] - **Supply**: The domestic and Asian PX loads are at a high level, and the maintenance volume in September is expected to further decrease, with an expected increase in production. The import volume from South Korea to China in August increased slightly [11] - **Demand**: The PTA load at the end of the month decreased slightly month - on - month. The maintenance volume in September decreased, and the average load is expected to be higher than that in August [11] - **Inventory**: The social inventory decreased year - on - year at the end of July, is expected to accumulate slightly in August, and will continue to accumulate in September [11] - **Cost and Profit**: PXN decreased by 33 dollars last month, and the short - process profit is relatively strong. The gasoline performance in the aromatics blending oil market improved slightly, and the gasoline cracking spread was weak [11][95] 4. PTA Fundamentals - **Capacity**: New capacity has been added in 2024 and 2025, such as the 250 - ton new capacity of Honggang Petrochemical (Phase III) in 2025 [127] - **Supply**: The PTA load at the end of the month decreased slightly month - on - month. The maintenance volume in September decreased, and the average load is expected to be higher than that in August [12] - **Demand**: The polyester load at the end of the month increased year - on - year, and the terminal situation has recovered but is still weak year - on - year [12] - **Inventory**: The PTA social inventory decreased year - on - month in August, and it is expected to continue de - stocking in September [12] - **Profit and Valuation**: The spot and futures processing fees increased month - on - month, but the overall processing fee is still weak [12] 5. Ethylene Glycol (MEG) Fundamentals - **Capacity**: New capacity is expected to be added in 2024 and 2025, such as the 80 - ton new capacity of Yulong Petrochemical 1 in 2025 [142] - **Supply**: The overall load of MEG has risen to a high level. The load of synthetic gas - based and ethylene - based production has increased. The import volume decreased slightly in July, and the arrival volume is expected to increase in the middle and late September [13][145] - **Demand**: The polyester load at the end of the month increased year - on - year, and the terminal situation has recovered but is still weak year - on - year [13] - **Inventory**: The port inventory decreased year - on - month, and the downstream factory inventory days decreased slightly. Although the domestic production increased in September, the port inventory is expected to remain low due to the concentrated arrival of ships in the middle and late period. In the medium term, inventory accumulation is expected [13] - **Cost and Profit**: The coal price was weakly volatile, and the ethylene price increased slightly. The valuation of MEG profit is relatively high [13][167] 6. Polyester and Terminal - **Polyester** - **Capacity**: New polyester filament devices have been commissioned, and new capacity has been added in 2024 and 2025, such as the 20 - ton new capacity of Hengchao in 2024 [184][187] - **Supply**: The operation rate has continued to recover, and the operation rates of polyester filament, short - fiber, and bottle - chip have increased [190][193] - **Inventory**: The inventory pressure of polyester filament is moderate, the short - fiber inventory is neutral year - on - year, and the bottle - chip inventory is still high [197][200] - **Profit**: The profit of polyester filament has improved [206] - **Terminal** - **Operation**: The operation rate is still weak year - on - year [210] - **Orders and Inventory**: Orders have continued to improve, inventory has decreased, and raw material inventory has increased [219] - **Consumption**: The growth rate of domestic textile and clothing demand has decreased, and exports are weak [224]

Report Summary 1) Report Industry Investment Rating - No information provided. 2) Core Viewpoints - The PTA market had limited overall fluctuations, with sufficient spot supply, a weakening spot basis, and a slight decline in prices. The expansion of the spread between PX and naphtha and the weak benzene price restricted the further increase in PX production. With the improvement in recent sales and inventory reduction, especially the significant reduction of filament inventory, profits were significantly repaired, but some downstream devices had strong maintenance expectations [2]. - The ethylene glycol price rebounded. The planned production cut of South Korean naphtha cracking units and the continuous postponement of the maintenance of overseas ethylene glycol units, especially Saudi Arabian units, would have a significant impact on the market outlook, boosting the ethylene glycol price. The later arrival volume of ethylene glycol decreased, polyester inventory was in good condition, and the downstream weaving load increased [2]. 3) Summary by Relevant Catalogs Market Data - INE crude oil price decreased from 485.2 yuan/barrel on August 29, 2025, to 483.5 yuan/barrel on September 1, 2025, a decrease of 1.70 yuan/barrel.
