Report Industry Investment Rating No relevant content provided. Core View of the Report - The polyester industry chain is operating weakly, and attention should be paid to macro - changes. The current situation is affected by the Sino - US trade war, and the meeting between the leaders of the two countries around the end of the month should be continuously monitored. The 4th Plenary Session of the 20th Central Committee will discuss the "15th Five - Year Plan" and economic work, which also needs attention [2]. - In terms of the cost side, there is a supply - surplus contradiction due to the slowdown in China's import demand after the National Day and the increase in US and Middle - East exports. The macro and fundamentals are in resonance, putting pressure on the fundamentals without a clear rebound driver [3]. - PX is under pressure due to the recovery of China's PX load to a relatively high level, few fourth - quarter maintenance plans, and capacity expansion of some devices. The downstream PTA plants have many maintenance plans, and the PX supply - demand support is limited [3]. - TA has a new device expected to be put into operation next month, with increasing inventory pressure after November. The cost - side support is weakening, and the demand is not strong during the peak season due to tariffs [3]. - The polyester start - up rate is 91.4% (down 0.1% month - on - month). After the National Day, the market calmed down, and filament inventory increased again. Terminal raw material procurement is mainly cautious. The weaving and texturing load decreased this week under high tariffs [4]. - PF has improved demand, with factory inventory reduced to a low level. The short - term supply - demand situation of direct - spun polyester staple fiber is better than that of the raw material end, and the processing fee is expected to be strong [4][5]. - PR's fundamentals have little change, with maintenance continuing but general demand. The spot processing fee of bottle chips is expected to fluctuate within a range, and attention should be paid to raw material price fluctuations [5].

Report Industry Investment Rating - The report does not provide an overall industry investment rating. However, for individual products, it gives a neutral rating with a mid - term cautious and bearish outlook for PX/PTA/PF/PR [4]. Core Viewpoints - The polyester industry chain is operating weakly during the peak season. The cost - end oil price is fluctuating, and the PX supply is increasing while the demand is weakening. PTA has a risk of inventory accumulation in the fourth quarter, and the demand side of the polyester industry has limited improvement and high inventory [1][2][4]. - The demand for PF has slightly improved, and short - term supply and demand conditions are better than the raw material side, but its upward momentum is weak. The processing fee of PR is expected to fluctuate within a range, and attention should be paid to raw material price fluctuations [3][4]. Summary by Relevant Catalogs I. Price and Basis - The TA main - contract spot basis is - 79 yuan/ton (with a环比 change of + 5 yuan/ton), and the PTA spot processing fee is 159 yuan/ton (with a环比 change of - 12 yuan/ton), and the main - contract disk processing fee is 304 yuan/ton (with a环比 change of - 12 yuan/ton) [2]. - Relevant figures include TA main - contract & basis & inter - period spread trend, PX main - contract trend & basis & inter - period spread, PTA East China spot basis, and short - fiber 1.56D*38mm semi - bright natural white basis [9][10][12]. II. Upstream Profits and Spreads - The PXN is 212 dollars/ton (with a环比 change of - 6.88 dollars/ton). Relevant figures include PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [1][18][21]. III. International Spreads and Import - Export Profits - Relevant figures include toluene US - Asia spread, toluene South Korean FOB - Japanese naphtha CFR, and PTA export profit [26][28]. IV. Upstream PX and PTA Start - up - China's PX load has gradually recovered to a relatively high level, and overseas start - up will further increase in the short term. China's PTA load is rising from a low level. Relevant figures show the load of PTA in China, South Korea, and Taiwan, as well as the load of PX in China and Asia [1][29][36]. V. Social Inventory and Warehouse Receipts - PTA has a risk of inventory accumulation in the fourth quarter. Relevant figures include PTA weekly social inventory, PX monthly social inventory, PTA total warehouse receipts + forecast volume, PTA warehouse warehouse - receipt inventory, PX warehouse - receipt inventory, and PF warehouse - receipt inventory [2][37][41]. VI. Downstream Polyester Load - The polyester start - up rate is 91.4% (with a环比 change of - 0.2%), and it is expected to remain stable with a slight increase in September. Relevant figures include filament production and sales, short - fiber production and sales, polyester load, direct - spinning filament load, polyester staple fiber load, polyester bottle - chip load, filament factory inventory days, and the operating rates of weaving, texturing, and dyeing in Jiangsu and Zhejiang [2][49][65].

Strategy - Unilateral: Neutral for PX/PTA/PF/PR, and cautiously bearish in the medium term [4]. - Cross - variety: Go long on PF processing fee at low prices: PF2511 - 0.855PTA2601 - 0.332MEG2601 [5]. - Cross - period: None [5].

Report Industry Investment Rating - PX/PTA/PF/PR are rated neutral [4] Core Viewpoints - The postponement of the maintenance of two PX units has narrowed the de - stocking range of PX in the fourth quarter, weakening the previous de - stocking support. Coupled with more PTA maintenance plans, PX prices have fallen and PTA processing fees have widened [1] - The recent oil price has been oscillating, and the Russia - Ukraine situation should be monitored. The PX load in China has gradually recovered, and the PX balance sheet in September has changed from de - stocking to a loose balance. However, PX is still in a low - inventory state [1] - The PTA load is rising from a low level. The short - term de - stocking fundamentals are okay, but there is a risk of inventory accumulation in the fourth quarter due to new device commissioning expectations. The demand recovery is limited, and the polyester load increase is restricted [2] - The polyester start - up rate shows signs of recovery, but order connection is insufficient. It is expected that the polyester load will remain stable with a slight increase in September [2] - The short - term supply - demand situation of direct - spinning polyester staple fiber is better than that of the raw material end, and the processing margin has widened. The bottle - chip processing fee is expected to fluctuate slightly, and there is still large supply - demand pressure under the new device commissioning [3] - For the strategy, it is recommended to go long on the PF processing fee at low prices in cross - variety trading, and there is no recommendation for cross - period trading [4] Summary by Directory Price and Basis - The report shows the TA main contract, basis, and inter - period spread trends; PX main contract trends, basis, and inter - period spread trends; PTA East China spot basis; and short - fiber 1.56D*38mm semi - bright natural white basis [9][10][13] Upstream Profit and Spread - The report presents PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [16][19] International Spread and Import - Export Profit - The report includes toluene US - Asia spread, toluene South Korea FOB - Japan naphtha CFR, and PTA export profit [24][26] Upstream PX and PTA Start - up - The report shows the PTA load in China, South Korea, and Taiwan, as well as the PX load in China and Asia [27][30][34] Social Inventory and Warehouse Receipts - The report presents the weekly social inventory of PTA, monthly social inventory of PX, total PTA warehouse receipts + forecast volume, PTA warehouse receipt inventory, PX warehouse receipt inventory, and PF warehouse receipt inventory [36][39][45] Downstream Polyester Load - The report shows the production and sales of filament and short - fiber, polyester load, direct - spinning filament load, polyester staple fiber load, polyester bottle - chip load, factory inventory days of various filaments, and the start - up rates of Jiangsu and Zhejiang looms, texturing machines, and printing and dyeing machines, as well as the profits of filament FDY and POY [49][51][62] PF Detailed Data - The report presents the polyester staple fiber load, factory equity inventory days of polyester staple fiber, 1.4D physical inventory, 1.4D equity inventory, recycled cotton - type staple fiber load, original - recycled spread, pure polyester yarn start - up rate, pure polyester yarn production profit, polyester - cotton yarn start - up rate, polyester - cotton yarn processing fee, and the available inventory days in pure polyester yarn and polyester - cotton yarn factories [71][73][83] PR Fundamental Detailed Data - The report shows the polyester bottle - chip load, bottle - chip factory inventory days, bottle - chip spot processing fee, bottle - chip export processing fee, bottle - chip export profit, price difference between East China water bottle chips and recycled 3A - grade white bottle chips, and bottle - chip inter - month spreads [91][93][101]

Report Industry Investment Rating No information provided. Core Views - The PTA maintenance plans have increased under low processing fees, such as Hengli and Dushan Energy planning to conduct maintenance in October and November respectively. The PTA futures closed up in a volatile manner on Wednesday, the negotiation atmosphere in the spot market was average, and individual mainstream suppliers reduced the contract supply in October, leading to a slight strengthening of the spot basis [1]. - In terms of the cost side, the oil price has been fluctuating recently, and attention should be paid to the Russia-Ukraine situation. The oil price has rebounded since last Friday. On the one hand, the Russia-Ukraine negotiations have been suspended again. On the other hand, the US military carried out a military operation in the offshore area of Venezuela, which raised concerns about Venezuela's national security. The PXN was 229 US dollars/ton (a month-on-month change of +1.63 US dollars/ton) the day before last. The negotiation on the floating price of PX was deadlocked, and the PXN weakened to 230 US dollars/ton and then fluctuated. Recently, the PX load in China has gradually recovered. With the increase in PTA maintenance, the PX balance sheet in September has changed from destocking to a loose balance, but the overall PX inventory is still at a low level. As the PTA devices resume operation, the PX will turn to destocking again. Considering the rigid demand for PX from new PTA devices, there is support below the PXN. Continued attention should be paid to window negotiations and warehouse receipt situations [2]. - In terms of TA, the spot basis of the TA main contract was -77 yuan/ton (a month-on-month change of +3 yuan/ton), the PTA spot processing fee was 130 yuan/ton (a month-on-month change of -1 yuan/ton), and the processing fee on the main contract's disk was 332 yuan/ton (a month-on-month change of +6 yuan/ton). The PTA load is increasing from a low level, and the near-term destocking fundamentals are acceptable. However, there is a pressure of inventory accumulation in the fourth quarter due to the expected commissioning of new devices. Recently, mainstream suppliers have been selling goods, and the market's spot supply is relatively abundant. At the same time, the recovery of the demand side is limited, and the order connection is insufficient under high inventory. The increase in polyester load is limited [2]. - In terms of demand, the polyester operating rate was 91.6% (a month-on-month increase of 0.3%). The current demand shows signs of recovery, but the order connection is insufficient, mainly with local scattered orders. The high inventory of grey fabrics is being depleted slowly. The market's expectation for the subsequent demand level is neutral to pessimistic. Most terminal raw material purchases maintain a cautious wait-and-see attitude, digesting previous stocks while following up with rigid demand. In terms of polyester load, the inventory of filament is not high but gradually accumulating. It is expected that the load of filament and staple fiber will continue to stabilize and slightly rebound in September. The load of bottle chips is expected to increase slightly, but the increase may be limited. It is expected that the polyester load will stabilize and slightly rebound in September, with the average monthly load likely to be below 91.5% [3]. - In terms of PF, the spot production profit was 175 yuan/ton (a month-on-month change of -6 yuan/ton). Direct-spun polyester staple fiber fluctuated and consolidated following the raw materials, and the load continued to increase slightly. As the price difference between high and low prices in the market narrowed, factory sales improved, inventory decreased, the demand for staple fiber at a low price was acceptable, the factory inventory was low, and currently, the inventory held by traders was small. In the short term, the supply-demand situation of direct-spun polyester staple fiber was better than that of the raw material side. Due to the relatively weak performance of raw materials, the processing margin of direct-spun polyester staple fiber expanded to over 1000 [3]. - In terms of PR, the spot processing fee of bottle chips was 454 yuan/ton (a month-on-month change of -11 yuan/ton). The fundamentals of bottle chips have not changed much. The current order receipt and shipment performance of bottle chips are average. It is reported that the industry's overall target of 20% production reduction and suspension in September remains unchanged. It is expected that the subsequent increase in bottle chip load will be limited, the overall inventory pressure of factories has decreased, and the processing fee of polyester bottle chips is expected to maintain small fluctuations. Under the pressure of the commissioning of the new Fuhai device in the future, the supply-demand pressure is still relatively large, and production reduction is needed for adjustment. It is expected that the spot processing fee of bottle chips will fluctuate within a range. Attention should be paid to the fluctuation of raw material prices [4]. - Strategy: For single-sided trading, the ratings for PX/PTA/PF/PR are neutral. For PX, since August, PX devices have been restarted intensively. With the increase in PTA maintenance, the fundamentals have weakened month-on-month, and the PXN has loosened. However, with low inventory and the restart of PTA, the PX will turn to destocking again, and there is support below the PXN. For TA, the PTA load is increasing from a low level, and the near-term destocking fundamentals are acceptable. However, there is a pressure of inventory accumulation in the fourth quarter due to the expected commissioning of new devices. Recently, mainstream suppliers have been selling goods, and the market's spot supply is relatively abundant. At the same time, the recovery of the demand side is limited, and the order connection is insufficient under high inventory. The increase in polyester load is limited. For PF, the demand for PF has improved slightly, the inventory has started to decrease, the demand at a low price is acceptable, and currently, the inventory held by traders is small. In the short term, the supply-demand situation of direct-spun polyester staple fiber is better than that of the raw material side, but its upward momentum is not strong. For PR, several major manufacturers have extended their maintenance plans. It is expected that the spot processing fee of bottle chips will fluctuate within a range. Attention should be paid to the fluctuation of raw material prices. For cross-variety trading, go long on the PF processing fee at low prices: PF2511 - 0.855PTA2601 - 0.332MEG2601. There is no strategy for cross-period trading [5]. Summary by Relevant Catalogs Price and Basis - Figures show the TA main contract, basis, and inter - period spread trends; PX main contract trends, basis, and inter - period spread; PTA East China spot basis; and short - fiber 1.56D*38mm semi - bright white basis [10][11][13] Upstream Profits and Spreads - Figures display PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [19][22] International Spreads and Import - Export Profits - Figures present the toluene US - Asia spread, toluene South Korean FOB - Japanese naphtha CFR, and PTA export profit [27][29] Upstream PX and PTA Start - up - Figures show the PTA load in China, South Korea, and Taiwan, as well as the PX load in China and Asia [30][33][37] Social Inventory and Warehouse Receipts - Figures present the weekly social inventory of PTA, monthly social inventory of PX, total PTA warehouse receipts + forecast volume, PTA warehouse receipt inventory, PX warehouse receipt inventory, and PF warehouse receipt inventory [38][41][42] Downstream Polyester Load - Figures show the production and sales of filament and short - fiber, polyester load, direct - spun filament load, polyester staple fiber load, polyester bottle chip load, filament factory inventory days, Jiangsu and Zhejiang loom start - up rate, Jiangsu and Zhejiang texturing machine start - up rate, Jiangsu and Zhejiang dyeing machine start - up rate, and filament profit [50][52][63] PF Detailed Data - Figures display the polyester staple fiber load, polyester staple fiber factory equity inventory days, 1.4D physical inventory, 1.4D equity inventory, recycled cotton - type staple fiber load, original - recycled price difference, pure polyester yarn start - up rate, pure polyester yarn production profit, polyester - cotton yarn start - up rate, polyester - cotton yarn processing fee, pure polyester yarn factory inventory available days, and polyester - cotton yarn factory inventory available days [72][76][83] PR Fundamental Detailed Data - Figures show the polyester bottle chip load, bottle chip factory bottle chip inventory days, bottle chip spot processing fee, bottle chip export processing fee, bottle chip export profit, East China water bottle chip - recycled 3A - grade white bottle chip price difference, bottle chip next - month spread, and bottle chip next - next - month spread [93][97][100]

Report Industry Investment Rating No relevant content provided. Core View of the Report - The cost side is affected by the intensification of the Israel - Iran conflict in the Middle East, leading to a significant increase in oil prices. If the conflict escalates and affects energy facilities or the Strait of Hormuz, oil prices may face further upward risks; if the situation is controlled and parties seek peace talks, the geopolitical premium may decline again [1]. - In the gasoline and aromatics sectors, the gasoline crack spread in the US has retraced again. With the substitution of new energy, the upside potential for gasoline crack spreads is limited, and the blending demand this year is not worth much expectation. The intermittent blending demand at home and abroad can be basically met by naphtha, which restricts the enthusiasm of aromatics entering the gasoline pool [1]. - For PX, the short - term unilateral trend of PX/PTA/PF/PR is bullish under the Israel - Iran conflict, but if the conflict eases, prices may fall. The supply - demand situation of PX remains tight due to unplanned overseas plant shutdowns, while the tightness of PTA's spot market liquidity has eased [5]. Summary According to the Table of Contents 1. Price and Spread - The report analyzes the trends of TA, PX, PF, and PR's main contracts, their basis, and inter - period spreads, as well as various processing fees and profit margins such as PX processing fees, PTA spot processing fees, short - fiber profits, and bottle - chip processing fees [8][9]. 2. PX and PTA Supply - This week, China's PX operating rate was 85.6% (down 0.2% week - on - week), and Asia's was 74.3% (down 1.3% week - on - week). Domestic PX load was basically stable, while overseas facilities had more changes. The Israel - Iran conflict led to the shutdown of PX plants in Iran and Israel, and the restart of Saudi Arabia's Rabigh aromatics plant was postponed. Several domestic PX plants are planned for maintenance at the end of the month, and the spot market is still short of goods [2]. - China's PTA operating rate was 79.1% (down 3.5% week - on - week), and the PTA spot processing fee was 412 yuan/ton (compared to 42 yuan last week). Some PTA plants reduced their loads or shut down as planned, and the tightness of the spot market's liquidity has eased [2]. 3. Inventory - The report presents the weekly social inventory of PTA, the monthly social inventory of PX, the total PTA warehouse receipts and forecast volume, PTA warehouse receipt inventory, PX warehouse receipt inventory, and PF warehouse receipt inventory [8][9]. 4. Demand - This week, the operating rate of looms in Jiangsu and Zhejiang was 65.0% (down 2.0% week - on - week), and the polyester operating rate was 92.0% (up 1.1% week - on - week). Domestic and foreign sales have entered the off - season, with terminal orders and operations showing a downward trend, but polyester has performed relatively well. After the raw material prices rose, there was a concentrated restocking, and the inventory of filament decreased. However, at high prices, the inventory pressure may increase [3]. 5. PF Supply, Demand, and Inventory - This week, the direct - spinning polyester staple fiber operating rate was 95.1% (up 3.0% week - on - week), the equity inventory days of polyester staple fiber factories were 12.1 days (up 0.6 days week - on - week), and the inventory of 1.4D polyester staple fiber increased. Affected by the Israel - Iran situation, the price of direct - spinning polyester staple fiber fluctuated upwards, but the increase was less than that of raw materials, and the processing margin was slightly compressed [3]. 6. PR Supply, Demand, and Inventory - This week, the bottle - chip factory operating rate (based on maximum capacity) was 80.7% (up 0.9%), the bottle - chip factory inventory was 17.4 days (up 1.9 days week - on - week), and the bottle - chip spot processing fee was 186 yuan/ton (down 129 yuan from last week). The overall transaction in the polyester bottle - chip market was average this week. Although some overseas customers made supplementary purchases, the processing fee is still under pressure in the short term. Major manufacturers have announced maintenance plans, which will have a greater impact on the bottle - chip load [4].
