Report Title - PX & PTA & MEG Strategy Report for September 2025 [1] Report Industry Investment Rating - Not provided in the given content Core Viewpoints - PX supply is expected to reach a high level in September, with short - process MX being abundant and new MX production adding to PX output. However, downstream TA maintenance is increasing, and with the continuous compression of TA processing fees, TA devices may have further maintenance. Thus, PX fundamentals are weak, and it may show a weak and volatile trend without significant crude oil fluctuations [150]. - For PTA, although the polyester operating load is rising and the fundamentals are improving, the price performance is weak, and the TA processing fee is still compressed below 200 yuan/ton. The "Golden September and Silver October" demand is facing challenges, with increasing external tariff risks. The TA price is expected to have support and show an overall volatile trend [150]. - MEG's operating load has climbed to a high level. In September, there are both maintenance and restart of devices. The port inventory is low, and the spot liquidity is tight. With supply contraction and demand increase, the port inventory is expected to remain low, and the short - term price may be volatile and strong [150]. Summary by Relevant Catalogs 1. PX&PTA&MEG Price: Follow Crude Oil Price Oscillation - **Futures Prices**: From July 31 to August 28, 2025, PTA futures closing price decreased from 4808 yuan/ton to 4792 yuan/ton (-0.3%), MEG increased from 4414 yuan/ton to 4465 yuan/ton (1.2%), and PX decreased from 6928 yuan/ton to 6886 yuan/ton (-0.6%) [6]. - **Basis and Spread**: For PTA basis, it changed from - 17 yuan/ton to - 20 yuan/ton (-17.6%); MEG basis changed from 71 yuan/ton to 64 yuan/ton (-9.9%); PX basis changed from 188 yuan/ton to 97 yuan/ton (-48.6%).

PX&PTA&MEG Supply Situation: Focus on Device Recovery - **PX**: As of August 29, Asian PX operating load was 75.6% (month - on - month increase of 2.7 percentage points), and China's was 83.3% (month - on - month increase of 3.4 percentage points). The 160 - million - ton PX device of Fuhua Group restarted in early September. Multiple new reforming devices are expected to be put into operation starting from August, which may increase PX output [33][58][59]. - **PTA**: As of August 29, PTA operating load was 70.4% (month - on - month decrease of 9.3 percentage points). There were device maintenance and new device production. The autumn maintenance plan is concentrated in September - October [37][60]. - **MEG**: As of August 28, the overall operating load of ethylene glycol in mainland China was 75.13% (month - on - month increase of 5.79%). There are device restart and maintenance plans in September [52][61]. 3. PX&PTA&MEG Import and Export Situation: Tariff Extension for 90 Days - **Imports and Exports in July 2025**: China's PX imports were 78.20 million tons (month - on - month increase of 2.17%), PTA exports were 37.42 million tons (month - on - month increase of 46.66%), and ethylene glycol imports were 59.14 million tons (month - on - month decrease of 4.27%) [64][65][76]. - **Polyester Exports**: In July 2025, the total polyester export was 120.33 million tons, with a month - on - month decrease of 3.68%. Different polyester products had different export trends [75][77]. 4. PX&PTA&MEG Inventory Situation: Downstream Finished Product Inventory Rebounds - **PTA**: Polyester factories' PTA raw material inventory increased, and the number of warehouse receipts decreased [86]. - **MEG**: As of August 25, the ethylene glycol port inventory in the East China main port area was about 50 million tons, reaching a low level [89]. 5. Polyester Demand Situation: Terminal Demand Faces Challenges - **Domestic Polyester Data**: As of August 29, the polyester operating load was 90.3% (month - on - month increase of 2.5%). The inventory days of some polyester products changed, and the cash flow also changed [92]. - **Terminal Demand**: In July, textile and clothing exports faced downward pressure. With the extension of tariffs for 90 days, the export expectation of Chinese textiles and clothing is expected to improve [106][103]. 6. PX&PTA&MEG Positioning Situation - **Futures Positions**: From July 31 to August 28, 2025, PTA total positions decreased from 1,493,200 lots to 1,360,753 lots, MEG total positions decreased from 357,146 lots to 320,792 lots, and PX total positions increased from 243,421 lots to 289,662 lots [119].
