Report Title - The Q4 2025 Quarterly Report on Polyolefins by Guantong Futures: New Capacity Commissioning Puts Pressure, Polyolefins to Oscillate Weakly [1] Core Viewpoints - Polyolefins are gradually exiting the maintenance season, with the operating rate expected to rise in October. Import profit is average, and import volume is expected to remain low. In Q4, new PE and PP capacities of 2.7 million tons/year and 950,000 tons/year will be commissioned respectively. Multiple units are scheduled to start operation by the end of the year, having little impact on the 01 contract. Attention should be paid to the commissioning progress of new capacities. The demand for polyolefins in Q4 will improve quarter-on-quarter but perform averagely compared to the same period in previous years. New orders are mediocre. Amid the global trade war, enterprises' early rush for exports and the pre - consumption of national subsidies may overdraw the Q4 demand. Although downstream enterprises have stocked up, they remain cautious. Crude oil prices will still face pressure in Q4, and the cost support for polyolefin prices is expected to be limited. Petrochemical inventories are at a neutral level compared to the same period in recent years. Recently, polyolefin traders' inventories have decreased but are still at a relatively high level compared to the same period in recent years. There is no actual anti - involution policy in the polyolefin industry yet. Anti - involution and the elimination of old - fashioned devices to solve the problem of overcapacity in the petrochemical industry are still macro - policies that will affect subsequent market conditions and are worthy of close attention. It is expected that polyolefins will oscillate weakly in Q4 under the scenario of both supply and demand increasing [5][110]. Summary by Directory Polyolefin Futures Price Trends - The report presents the daily K - lines of the plastic weighted contract and the PP weighted contract [8][10] Plastic Spot Prices - It shows the spot prices of plastics in North China and the spot price (CFR, mid - price) of linear low - density polyethylene in the Far East [14][16] Plastic Basis Trends - Since 2025, the plastic basis has been continuously weakening from a historical high, reaching a low of - 136 yuan/ton in late July.

In August 2025, the net PE imports were 834,200 tons, a decrease of 27.36% year - on - year. The cumulative net PE imports from January to August 2025 were 8.2518 million tons, a decrease of 2.66% year - on - year. The LLDPE import profit is currently negative, and with the release of domestic capacities, the net PE imports are expected to remain low [72] PP Imports and Exports - In August 2025, China's PP imports were 247,000 tons, a decrease of 21.39% year - on - year and 12.54% month - on - month, at the lowest level in the same period in recent years.

The cumulative PP exports from January to August 2025 were 2.1035 million tons, an increase of 29.03% year - on - year. The PP drawstring import window is closed, and the import volume is expected to be low [78] Polyolefin Downstream - From January to August 2025, the cumulative output of plastic products was 52.1815 million tons, a year - on - year increase of 3.6%, but the cumulative year - on - year growth rate decreased slightly. In August, the year - on - year growth rate was - 4.1%. The cumulative export value of plastic products from January to August 2025 was 500.396 billion yuan, a year - on - year decrease of 0.5%, with a slightly rising growth rate but still negative. In August, the year - on - year growth rate dropped to 0.8%, a decrease of 2.5 percentage points month - on - month. From January to August 2025, the cumulative year - on - year growth rate of the domestic total retail sales of consumer goods was 3.4%, slower than the 3.7% from January to July. The cumulative year - on - year growth rate of the total retail sales of consumer goods has been slowing down since May, indicating increasing pressure on domestic demand. As of the week of September 26, the PE downstream operating rate increased by 1.21 percentage points week - on - week to 44.13%, and the PP downstream operating rate increased by 0.40 percentage points week - on - week to 51.85%, both at relatively low levels in the same period in previous years [83][89][94] Polyolefin Inventories - After the Spring Festival in 2025, petrochemical inventories were at an average level compared to the same period in recent years. As of September 26, petrochemical inventories decreased by 30,000 tons week - on - week to 585,000 tons, 105,000 tons lower than the same period last year. Recently, polyolefin traders' inventories have decreased but are still at a relatively high level compared to the same period in recent years [102] Polyolefin Profits - In September, the coal - based and oil - based PE profits decreased slightly due to a slight decline in PE prices. In September, the profits of all PP production processes declined to varying degrees. The coal - based PP production process remained profitable, while the other processes were still in the red, with the MTO process having a relatively large loss [108]

Report Industry Investment Rating - No relevant information provided Core Viewpoints - The current PVC market has a weak fundamental situation. With the release of new production capacity and high industry operating rates, supply pressure continues to increase. Given the downturn in the real estate industry and the slowdown in exports, demand is unlikely to exceed expectations. Although there may be a seasonal maintenance peak in October leading to a temporary tightening of supply, if demand does not improve simultaneously, the inventory reduction speed will remain slow. It is expected that the 2601 contract will fluctuate weakly in the future [2][3][4] Summary by Related Catalogs PVC Supply Pressure - The PVC market has entered the traditional peak season, but factors such as weak demand and increased supply have put continuous pressure on futures prices, resulting in a "peak season without prosperity" situation. The trading logic in the PVC futures market has returned to fundamentals. Although short - term supply has decreased slightly, downstream demand remains weak, and the overall fundamentals are weak [2] - In 2025, new PVC production capacity has been continuously put into operation, increasing supply pressure. New devices of Fujian Wanhua and Tianjin Bohua Development have been put into operation in recent months, bringing significant supply increments. Although some devices of Henan Yuhang and Heilongjiang Haohua were shut down for maintenance in September, and some devices of Shaanxi Beiyuan, Gansu Jinchuan, and Xinjiang Zhongtai Shengxiong continued to be under maintenance, the industry operating rate is expected to increase slightly month - on - month and remain at a relatively high level in recent years. This means that short - term supply reduction is completely offset by long - term supply increment, and market supply pressure has increased [2] Cost Support - The production cost of calcium carbide - based PVC in China is mainly affected by calcium carbide prices. Recently, the domestic calcium carbide market has recovered, and prices have risen slightly, providing phased support for PVC costs. As of the week of September 19, due to the increase in the purchase price of raw material calcium carbide, the weekly average production cost of national calcium carbide - based PVC enterprises was 5132 yuan/ton, a month - on - month increase of 2.41%. Meanwhile, affected by the increase in ethylene prices, the production cost of ethylene - based PVC in China has also slightly increased. As of the week of September 19, the weekly average production cost of national ethylene - based PVC enterprises was 5617 yuan/ton, a month - on - month increase of 0.018%. Although the increase in calcium carbide and ethylene prices has provided some support for PVC futures prices, it is difficult to drive prices to rise significantly [2] Supply and Inventory - Supply surplus has led to continuous accumulation of social inventory. As of the week of September 19, the domestic PVC industry inventory was 1.3005 million tons, a month - on - month increase of 1.11%, with 12 consecutive weeks of inventory accumulation; the PVC social inventory was 953,700 tons, a month - on - month increase of 2.03% and a year - on - year increase of 11.76% [3] Demand Pressure - In terms of domestic demand, the real estate industry, as the largest end - consumption area of PVC, has been in a continuous downturn, seriously dragging down the demand recovery progress. From January to August 2025, the year - on - year decline of domestic housing construction area, new construction area, and completion area was in double - digits. In September, although the operating rate of PVC downstream enterprises has increased, the overall order situation is still average, and end - users mainly purchase at low prices, resulting in a dull market trading atmosphere [3] - In terms of export demand, affected by India's anti - dumping tax, some enterprises have "rushed to export", overdrafting part of the demand. In September, the export pace has significantly slowed down, and the order increment is limited. Although domestic enterprises are actively exploring emerging markets such as Africa and Southeast Asia, it is difficult to form a stable demand increment in the short term due to multiple factors. Overall, the supporting effect of exports on PVC prices has weakened [3] Market Outlook - Currently, the PVC market fundamentals are weak. With new production capacity coming on stream and high industry operating rates, supply pressure keeps rising. Given the real - estate slump and slower exports, demand won't likely outperform. Despite a possible seasonal maintenance peak in October that may tighten supply temporarily, if demand doesn't improve in tandem, inventory drawdown will remain slow. The 2601 contract is expected to trade in a weak, sideways pattern [4]

Report Overview - Report Date: September 23, 2025 [3] - Analysts: Wang Jing (F0235424/Z0000771), Su Miaoda (F03104403/Z0018167) [1] Market Summary Futures Market Performance - As of September 23 closing, most domestic futures main contracts declined. Beans No. 2, rapeseed meal, soybean meal, soybean oil, and caustic soda dropped over 3%; palm oil, polysilicon, and soda ash fell over 2.5%. Shanghai gold and silver rose over 1%. CSI 300 Index Futures (IF) main contract rose 0.25%, SSE 50 Index Futures (IH) rose 0.26%, CSI 500 Index Futures (IC) dropped 0.78%, and CSI 1000 Index Futures (IM) fell 1.16%. 2-year Treasury Bond Futures (TS) main contract fell 0.05%, 5-year (TF) fell 0.13%, 10-year (T) fell 0.21%, and 30-year (TL) fell 0.67% [6] Capital Flow - As of 15:15 on September 23, in terms of capital inflow to domestic futures main contracts, CSI 1000 2512 had an inflow of 5.797 billion, Shanghai Gold 2512 had 3.357 billion, and CSI 300 2512 had 3.343 billion. In terms of outflow, Rapeseed Oil 2601 had an outflow of 789 million, Soybean Oil 2601 had 489 million, and Palm Oil 2601 had 429 million [8] Core Views Copper - Shanghai copper opened low and moved lower, oscillating weakly. Supply of copper ore and refined copper is tight. As of September 19, China's spot TC was -40.64 dollars/dry ton, RC was -4.05 cents/pound, remaining weakly stable. Many smelters had maintenance in September, with small and medium - sized ones under profit pressure. In August, SMM China's electrolytic copper output was 1.1715 million tons, a 0.24% MoM decrease but a 15.59% YoY increase. Affected by policies, scrap copper supply will decline significantly in September, and electrolytic copper output is expected to drop sharply. In August, imported copper quantity decreased to 307,200 tons, a MoM decrease of 27,300 tons. Demand is driven by pre - holiday restocking, reducing SHFE inventory. Fundamentals are tight, demand is resilient, but overseas macro factors still impact Shanghai copper, leading to narrow price fluctuations [10] Crude Oil - The peak travel season for crude oil has ended. EIA data shows a significant unexpected draw in US crude oil inventories, but a larger - than - expected build in refined oil inventories, increasing overall oil product inventories and reducing US refinery operating rates by 1.6 percentage points. Starting from October 2025, OPEC+ will adjust production by 137,000 barrels per day from the additional voluntary cut of 1.65 million barrels per day announced in April 2023, increasing pressure in Q4. Saudi Aramco cut the price of its flagship Arabian Light crude oil for October shipments to Asia by 1 dollar/barrel. With geopolitical risks not escalating further, the end of the consumption peak season, weak US non - farm payroll data, and OPEC+ accelerating production increase, it is recommended to short on rallies [11][12] Asphalt - Last week, asphalt operating rate dropped 0.5 percentage points to 34.4%, still at a relatively low level in recent years. In September, domestic asphalt production is expected to reach 2.686 million tons, a MoM increase of 273,000 tons (11.3%) and a YoY increase of 683,000 tons (34.1%). Downstream operating rates rose, but road asphalt operating rate is still at the lowest level in recent years due to funds and weather. National shipments increased 31.10% MoM to 313,600 tons, at a neutral level. Refinery inventory decreased but is still at a low level in recent years. With new production and weather and fund constraints, supply surplus is intensifying, and with the recent decline in crude oil futures prices, asphalt cost support is weakening, and its futures price is expected to decline [13] PP - PP downstream operating rate rose 0.59 percentage points to 51.45%, at a relatively low level in the same period over the years. On September 23, new maintenance devices increased, and PP enterprise operating rate dropped to around 80%, at a neutral - low level. The proportion of standard - grade拉丝 production remained around 24.5%. Petrochemical enterprises' destocking in September was average, and petrochemical inventory is at a neutral level in recent years. With the Fed's 25 - basis - point rate cut, increased US distillate inventories, and expected increased Iraqi crude oil exports, crude oil prices fell. New capacity has been put into operation, and maintenance devices have increased recently. Although downstream is entering the peak season, current peak - season demand is lower than expected, and there is no large - scale centralized procurement. It is recommended to wait and see [14][15] Plastic - On September 23, there were few changes in maintenance devices, and the plastic operating rate remained around 85%, at a neutral level. PE downstream operating rate rose 0.75 percentage points to 42.92%. The agricultural film industry is entering the peak season, with increasing orders and raw material inventories but at a slower pace. Petrochemical enterprises' destocking in September was average, and petrochemical inventory is at a neutral level in recent years. With the Fed's rate cut and expected increased Iraqi crude oil exports, crude oil prices declined. New capacity has been put into operation, and the plastic operating rate has decreased. Although the agricultural film peak season is coming, the peak - season effect is not as expected. It is recommended to wait and see [16] PVC - The price of upstream calcium carbide in the northwest region is stable. PVC operating rate decreased 2.98 percentage points to 76.96%, at a neutral - high level in recent years. In the peak season, PVC downstream operating rate continued to increase, exceeding last year's level but still low compared to other years. India postponed the BIS policy for six months to December 24, 2025. Chinese PVC exports are expected to weaken in Q4, but export orders have increased recently. Social inventory continued to rise and is still high. The real estate market is still in adjustment. New capacity has been put into operation. With cost support strengthening and pre - holiday downstream stocking, but new production resuming and a low basis, PVC is expected to face downward pressure [18] Urea - Urea opened low and moved high, closing flat. The spot market remains weak, with limited improvement in sales after price cuts. Urea daily output has returned to over 190,000 tons. Before the holidays, downstream buyers stock up at low prices, and industrial demand is mainly for rigid needs. The compound fertilizer factory operating rate increased but at a slower pace, with high finished - product inventory. Urea factory inventory is increasing and is much higher than in previous years. The supply - demand situation remains loose, and it is necessary to monitor the progress and intensity of pre - holiday stocking [19][20]

Report Industry Investment Rating - Not provided in the document Core Viewpoints - The fundamentals show that the comprehensive profit of enterprises has declined, the valuation pressure has decreased, the maintenance volume is low, and the production is at a historical high. In the short term, multiple new devices will be tested. On the downstream side, domestic operations have improved. Regarding exports, the anti - dumping tax rate in India has been determined, and exports are expected to weaken after implementation. The cost of calcium carbide has continued to rebound, while caustic soda has declined, leading to stronger overall valuation support. In the medium term, the industry is continuously suppressed by the significant increase in production capacity and the continuous decline in real - estate demand, and the industry pattern has deteriorated. It is necessary to rely on export growth or the implementation of policies to clear old devices to consume the excess domestic production capacity. Overall, given the current situation of strong supply and weak demand in China, with the weakening export outlook, even if the downstream has improved recently, it is still difficult to change the pattern of oversupply. The fundamentals are poor. In the short term, there will be a small rebound due to stronger valuation support, improved domestic demand, and a better commodity atmosphere. In the medium term, pay attention to short - selling opportunities on rallies [11] Summary by Directory 1. Weekly Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is reported at 2,600 yuan/ton, a week - on - week increase of 200 yuan/ton; the price of Shandong calcium carbide is reported at 2,840 yuan/ton, a week - on - week increase of 60 yuan/ton; the price of medium - grade semi - coke in Shaanxi is 680 yuan/ton, a week - on - week increase of 20 yuan/ton. In terms of profit, the comprehensive profit of chlor - alkali integration has decreased, while the profit of ethylene - based production has increased slightly. Currently, the valuation support is neutral [11] - **Supply**: The PVC capacity utilization rate is 77%, a month - on - month decrease of 3%. Among them, the utilization rate of calcium carbide - based production is 76.9%, a month - on - month decrease of 2.5%; the utilization rate of ethylene - based production is 77.1%, a month - on - month decrease of 4.2%. Last week, the supply - side load decreased mainly due to the reduced loads of enterprises such as Shaanxi Beiyuan, Gansu Jinchuan, Zhongtai, Henan Yuhang, and Haohua. The load is expected to pick up slightly next week. The overall maintenance volume in September is expected to decline, and multiple devices are expected to be commissioned and put into production, further increasing the supply pressure [11] - **Demand**: Regarding exports, the final anti - dumping tax rate ruling result in India has been announced, and China's tax rate is at a significant disadvantage compared to other countries. Exports are expected to decline after implementation. The operations of the three major downstream industries continued to improve last week. The load of the pipe industry is 39.1%, a month - on - month increase of 1.5%; the load of the film industry is 76.9%, remaining flat month - on - month; the load of the profile industry is 39.4%, a month - on - month increase of 0.2%. The overall downstream load is 49.2%, a month - on - month increase of 1.7%. The overall downstream operations have stabilized and improved. Last week, the pre - sales volume of PVC was 756,000 tons, a week - on - week increase of 67,000 tons [11] - **Inventory**: Last week, the in - factory inventory was 306,000 tons, a week - on - week decrease of 4,000 tons; the social inventory was 954,000 tons, a week - on - week increase of 19,000 tons; the overall inventory was 1.26 million tons, a week - on - week increase of 16,000 tons; the number of warehouse receipts continued to rise. Currently, it is still in the inventory accumulation cycle, and the upstream inventory is gradually transferred to the mid - stream. Under the pattern of strong supply and weak demand, the inventory accumulation is expected to continue [11] 2.

Supply Side - In 2025, the production capacity of PVC will be significantly increased, mainly concentrated in the third quarter. Multiple enterprises such as Xinpu Chemical, Jintai Chemical, and Wanhua Chemical (Phase II) will put new production capacity into operation. The total planned new production capacity in 2025 is 2.5 million tons/year [61][66] 6. Demand Side - The operating loads of the three major downstream industries of PVC have continued to improve. The operating rates of pipes, films, and profiles have either increased or remained stable. The pre - sales volume of PVC has also increased. However, regarding exports, due to the anti - dumping tax rate ruling in India, exports are expected to decline [78][11]

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: 01 - 05 reverse spread; Cross - variety: None [3] Core View - The supply of PE is expected to increase due to device restarts, while the PP device production profit has shrunk significantly, leading to a decline in PP开工. The downstream demand is in the seasonal improvement stage of "Golden September", but the demand fulfillment rate is slow and the support is limited. The cost support has weakened as oil prices are under pressure and the external propane has corrected [2] Summary According to Related Catalogs 1.
