Report Title - PVC 2025 Q4 Report: New Capacity Launch vs. Anti-Involution Game [1] Report Industry Investment Rating - Not provided Core Views - Cost side: Calcium carbide prices rose due to coal price increases and orderly power consumption, but with overall oversupply, the room for further price increases to drive up PVC prices is limited. Under the "alkali for chlorine" model, current cash flows have not led to the shutdown of PVC plants. PVC operating rates have reached relatively high levels for the same period in history. From October to November, PVC will enter the autumn maintenance season, but the new capacity of 1.4 million tons/year put into operation in August - September will be fully released in Q4, and the 300,000 tons/year capacity of Jiahua Energy may be put into operation in Q4, so it is expected that autumn maintenance will not offset the increase from new capacity. The six - department joint plan for stable growth in the building materials industry has not yet had actual policies implemented in the PVC industry. Anti - involution and the elimination of old plants to solve the problem of overcapacity in the petrochemical industry are macro - policies that will affect future market trends. From January to August 2025, the real estate market was still in adjustment, with significant year - on - year declines in investment, new construction, and completion areas, and further declines in year - on - year growth rates of investment, sales, and completion. The weekly transaction area of commercial housing in 30 large - and medium - sized cities was at the lowest level for the same period in history, and real estate improvement still requires time. In August, China's manufacturing PMI was 49.4%, up 0.1 percentage point from the previous month, with improved manufacturing sentiment but still below the boom - bust line. PVC downstream operating rates have not significantly improved and are at a low level since March. Downstream products are cautious about restocking. Q4 is the peak construction season for real estate projects, and domestic consumption may increase seasonally, so PVC demand may improve slightly. The export growth rate of PVC floor coverings has slowed significantly. India postponed the BIS policy for another six months until December 24, 2025. China Taiwan's Formosa Plastics' October quotation was stable. On August 14, India announced a new anti - dumping duty on imported PVC, with an increase of about $50/ton for the Chinese mainland. China's PVC export outlook is weakening in Q4. Currently, PVC social inventory is rising, with high pressure, and warehouse receipts are at a historical high, and the PVC basis is low, with supply still in surplus. It is expected that PVC will mainly seek a bottom through oscillations, and after continuous price declines, its valuation is low and the room for further decline is limited. Of course, favorable real estate and anti - involution policies and improved external demand will stimulate PVC to rise periodically, especially in October when major policies may be introduced. For arbitrage, a 1 - 5 reverse spread is recommended [6][102]. Summary by Relevant Catalogs PVC Price Trends - Indian PVC spot prices have risen slightly since April 2025, and China's PVC spot export profits have increased slightly. After the main contract shifted to the 2601 contract, the spot price in East China again became deeply discounted. Recently, the 01 basis has rebounded slightly but is still at a relatively low level for the same period in recent years. PVC2601's top 20 net positions have always been in a short position. PVC warehouse receipts decreased from the historical high to 0 at the beginning of 2025 but then continued to rise and reached a new historical high due to weak spot demand and the futures still at a premium to the spot [15][20][25]. PVC Upstream - Affected by orderly power consumption, the calcium carbide operating rate dropped to 64% after March, at a low level. With the increase in the cost of semi - coke, calcium carbide prices rebounded continuously from a low level in September, with a rise of 210 yuan/ton in the northwest region but still about 200 yuan/ton lower than the end of last year. Semi - coke prices also increased significantly in September. Calcium carbide profits were stable but still in a loss state, and the semi - coke loss margin was stable, with the operating load rising to a neutral level of 56% [33]. PVC Profits - The continuous decline in PVC spot prices has led to losses in both the calcium carbide and ethylene methods of PVC production. However, under the "alkali for chlorine" model, current cash flows have not led to the concentrated shutdown of PVC plants [40]. PVC Output and Operating Rates - In August 2025, PVC output increased by 3.43% month - on - month to 2.0733 million tons, a year - on - year increase of 7.09%. From January to August 2025, cumulative PVC output was 16.086 million tons, a year - on - year increase of 4.04%, at the highest level for the same period in recent years. The PVC maintenance loss in August decreased by 3.22% month - on - month to 577,100 tons, a year - on - year decrease of 9.77%. From January to August 2025, the cumulative PVC maintenance loss was 4.2349 million tons, a year - on - year decrease of 11.24%, at a relatively low - to - neutral level for the same period in recent years. In August 2025, the PVC operating rate was 78.23%, a month - on - month increase of 1.13 percentage points and a year - on - year increase of 3.12 percentage points, at a relatively high level for the same period in history. Supported by the comprehensive profit of chlor - alkali, the PVC operating rate has remained at a relatively high level for the same period in history in the past three months. As of the week of September 26, affected by plants such as Heilongjiang Haohua and Gansu Jinchuan, the PVC operating rate increased by 2.01 percentage points month - on - month to 78.97%, rising to a relatively high level for the same period in recent years [48][51]. PVC New Capacity - Although the new capacity of the calcium carbide method has slowed down due to poor profits and environmental protection policies, there were still multiple sets of new ethylene - based PVC capacity put into operation in 2025, especially in August - September, and most are located in East China. Wanhua Chemical's 500,000 tons/year capacity was put into mass production in August, Tianjin Bohua's 400,000 tons/year capacity is expected to achieve stable production by the end of September after trial production in August, Qingdao Gulf's 200,000 tons/year capacity was put into operation in early September and is currently close to full - load production, and Gansu Yaowang's 300,000 tons/year capacity is in the trial - run stage in September. Attention should also be paid to the commissioning progress of Jiaxing Jiahua's 300,000 tons/year capacity [54]. PVC Maintenance - In addition to long - term shutdowns of plants such as Taishan Yanhua and Shandong Dongyue, a few newly added plants in 2025, such as Suzhou Huasu and Salt Lake Magnesium, are still under maintenance. From October to November, PVC will enter the autumn maintenance season, but it is expected that with the comprehensive profit of chlor - alkali, autumn maintenance will not offset the increase from new capacity [56]. PVC Imports and Exports - In August 2025, PVC imports were at the lowest level for the same period in history, and exports decreased month - on - month due to concerns about Indian anti - dumping duties but still remained at a relatively high level. The proportion of China's exports to India dropped to 39.22%. The net export volume of PVC in August decreased to 271,700 tons month - on - month, a month - on - month decrease of 11.24% and a year - on - year increase of 49.86%, still at the highest level for the same period in recent years. In September, there was still a small profit in PVC exports, but Indian anti - dumping duties and the BIS certification policy will suppress China's PVC exports in Q4. China's PVC production capacity accounts for 45% of the global total. While the domestic real estate market is in adjustment, developing countries such as India and Vietnam have strong demand for PVC but insufficient domestic production capacity. Although India's anti - dumping policy is unfavorable for China's exports to India, China can increase exports to other countries like Vietnam, but this will take time, and it is expected that this shift cannot fully fill the Indian gap in Q4 [63][73]. Real Estate Data - From January to August 2025, the year - on - year decline in national real estate development investment widened by 0.9 percentage points to - 12.9% compared to January - July. The year - on - year decline in national land purchase fees widened by 1.3 percentage points to - 10.2%. The year - on - year decline in national housing construction area widened by 0.1 percentage point to - 9.3%. From January to August, the sales area of commercial housing was 57.304 million square meters, a year - on - year decrease of 4.7%, and the sales volume was 5.5015 trillion yuan, a decrease of 7.3%. As of the week of September 21, the transaction area of commercial housing in 30 large - and medium - sized cities rebounded by 9.49% week - on - week but was at the lowest level for the same period in recent years. From January to August, the housing completion area was 27.694 million square meters, a year - on - year decrease of 17.0% [79][84][88]. PVC Floor Covering Exports - In August, the export volume of PVC floor coverings decreased by 1.50% month - on - month to 347,800 tons, a year - on - year decrease of 13.49%, at the lowest level for the same period in recent years. From January to August 2025, the cumulative export volume of PVC floor coverings was 2.795 million tons, a year - on - year decrease of 11.33%. Affected by the global trade war, especially the Sino - US trade war, China's PVC floor covering exports have performed poorly [92]. PVC Downstream Operating Rates - Despite the government's introduction of multiple real estate stimulus policies, the performance of the PVC downstream in 2025 has been cautious, and the recovery of operating rates has been slow. As of the week of September 26, the PVC downstream operating rate decreased by 1.50 percentage points month - on - month to 47.76%, a year - on - year increase of 2.99 percentage points. The policies have not yet been transmitted to the PVC demand side, and the demand for downstream PVC pipes and profiles is at a low level for the same period in history [97].

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. Recently, with stable spot prices and continuous decline in futures prices, the plastic basis has rebounded to around 200 yuan/ton, at a relatively low - neutral level. The PP basis has declined slightly recently but remains at a neutral position [23][29] Plastic Production - In August 2025, the PE maintenance volume decreased by 9.63% month - on - month to 457,900 tons, an increase of 25.42% year - on - year.

Recently, the operating rate has risen to around 85% and is currently at a neutral level. With the planned restart of some maintenance units at the end of September, the plastic operating rate is expected to rise slightly [39] Plastic Under - Maintenance Units - Besides long - term shut - down units such as those of North Huajin HDPE and Shenyang Chemical's full - density units, new units in 2025 like those of Lianyungang Petrochemical HDPE and Zhonghan Petrochemical LLDPE are still under maintenance [41] Plastic Planned Maintenance Units in Q4 - According to Longzhong Information, there are not many PE units planned for maintenance in Q4 2025, involving a total capacity of 3.18 million tons. Some units will be under maintenance for more than 30 days [44] Plastic New Capacities - In the first three quarters of 2025, multiple new capacities were commissioned, with a total of 3.43 million tons/year. In Q4 2025, the expected new capacity is 2.7 million tons. Some new capacities are expected to be commissioned in October, while others at the end of the year, having little impact on the 2025 output. There is also a possibility of delay in the commissioning of new capacities in Q4 [48] PP Production - In August 2025, the PP maintenance volume decreased by 8.76% month - on - month to 657,900 tons, an increase of 8.89% year - on - year. The cumulative PP maintenance volume from January to August 2025 increased by 5.13% year - on - year to 5.0087 million tons, at the highest level in the same period in history. In August 2025, the PP output increased by 2.32% month - on - month to 3.5045 million tons, an increase of 18.00% year - on - year. The cumulative PP output from January to August 2025 increased by 16.92% year - on - year to 26.3476 million tons, at the highest level in the same period in history [52] PP Operating Rate - In August 2025, the PP operating rate increased by 1.65 percentage points month - on - month to 78.80%, an increase of 3.55 percentage points year - on - year, at a relatively low - neutral level. Recently, the operating rate has dropped to around 79% due to new maintenance units, and the production ratio of standard - grade drawstring has risen to around 30%. It is expected that the operating rate will recover in early October [57] PP Under - Maintenance Units - Besides long - term shut - down units such as those of Dalian Petrochemical and Wuhan Petrochemical, new units in 2025 like those of Qilu Petrochemical and Luoyang Petrochemical are still under maintenance [60] PP Planned Maintenance Units in Q4 - In Q4, multiple PP units are planned for maintenance, and the maintenance is expected to be concentrated from October to November [63] PP New Capacities - In the first three quarters of 2025, 4.155 million tons of new PP capacities were commissioned. In Q4 2025, the expected new capacity is 950,000 tons, with some units planned to be commissioned in December [66] Plastic Imports and Exports - In August 2025, China's PE imports were 950,200 tons, a decrease of 22.14% year - on - year and 14.17% month - on - month, at the lowest level in the same period in previous years. The cumulative PE imports from January to August 2025 were 8.9816 million tons, a decrease of 0.84% year - on - year. In August 2025, China's PE exports were 116,000 tons, an increase of 61.83% year - on - year and 14.12% month - on - month, at the highest level in the same period in previous years.

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 imports from January to August 2025 were 2.1676 million tons, a decrease of 9.77% year - on - year. In August 2025, China's PP exports were 275,900 tons, an increase of 29.83% year - on - year and 4.76% month - on - month, at the highest level in the same period in previous 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.

1. Report Industry Investment Rating - The investment view on LPG is "oscillating bearish" [4] 2. Core View of the Report - In the short - term, PG prices have fallen from high levels. The upstream PG fundamentals lack obvious drivers and tend to be weak. The supply - demand of propylene in the intermediate link is under pressure, and the short - term demand for PP is saturated with a shutdown expectation in the later period. The PDH profit is expected to decline further. Attention should be paid to the flow of warehouse receipts in the market, macro and geopolitical risks [4] 3. Summary According to Related Catalogs 3.1 Market Review - The main contract of LPG futures declined, with a fluctuation range of 4230 - 4490 yuan/ton. In the first half of the week, the international crude oil price dropped, suppressing the market trend. Both domestic and foreign spot prices fell, and the sentiment of market participants was weak, leading to a rapid decline in the market. However, the domestic propane demand increased month - on - month, the combustion demand improved successively, and the demand expectation increased. In the second half of the week, the crude oil price rebounded, and the market rebounded slightly after reaching the bottom [5] 3.2 Domestic LPG Delivery Product Spot Price and Basis - **Spot Price**: In different regions, the prices of civil gas, imported gas, and ether - post - C4 have different changes. For example, in the East China region, the average price of civil gas decreased by 0.50% week - on - week; in the South China region, the price of Maoming civil gas remained unchanged week - on - week [7] - **Basis**: The weekly average basis in East China was 126.80 yuan/ton, in South China was 357.80 yuan/ton, and in Shandong was 301.80 yuan/ton. The total number of LPG warehouse receipts increased by 1353 to 14327 lots, and the lowest deliverable area was East China [4] 3.3 LPG Futures Price, Inter - month Spread, and Cross - month Spread - **Futures Price**: The prices of different LPG futures contracts (PG01 - PG12) showed different degrees of decline compared with the previous week and month. For example, PG01 decreased by 4.36% week - on - week and 1.83% month - on - month [8] - **Inter - month Spread**: The inter - month spreads (such as PG01 - PG02, PG02 - PG03, etc.) also had different changes compared with the previous week and month. For example, the spread of PG01 - PG02 decreased by 6.06% week - on - week and increased by 3.33% month - on - month [8] - **Cross - month Spread**: The cross - month spreads (such as PG01 - PG03, PG02 - PG04, etc.) also showed different trends. For example, the spread of PG01 - PG03 decreased by 6.04% week - on - week and 4.76% month - on - month [8] - **Arbitrage**: There are month - to - month and cross - month arbitrage strategies. For example, in month - to - month arbitrage, the spread between PG2511 and PG2512 was 7.9 on the day, and the z - score was 1.7318 [8] 3.4 Refinery Device Maintenance Plan - **Main Refineries**: Many main refineries in China have device maintenance plans in 2025, including full - plant maintenance and partial device maintenance of some refineries such as Beihai Refining and Chemical, Hainan Refining and Chemical, etc. [9] - **Local Refineries**: Local refineries in Shandong, Northeast, Central China, and Northwest regions also have corresponding device maintenance plans, such as the full - plant maintenance of Shenchi Chemical, Xin泰 Petrochemical, etc. [9] 3.5 LPG Production Device and PDH Device Maintenance Plan - **LPG Production Device**: Some LPG production enterprises in China have device maintenance plans in 2025, such as Zhenghe Petrochemical, Huaxing Petrochemical, etc. [10] - **PDH Device**: Some PDH devices in China are in normal operation, while some are in shutdown or maintenance. For example, Qingdao Jinneng Phase I is in shutdown for maintenance, and it is expected to restart on October 1st [11] 3.6 Fundamental Factors Affecting LPG - **Supply**: Last week, the total commercial volume of LPG was about 539,200 tons. The commercial volume of civil gas was 211,200 tons (a decrease of 4.76%), industrial gas was 212,500 tons (a decrease of 0.75%), and ether - post - C4 was 170,130 tons (a decrease of 1.64%). The arrival volume of LPG last week was 650,000 tons. A refinery in Shandong plans to conduct maintenance this week, and some enterprises will reduce production, so the domestic commercial volume is expected to decline [4] - **Demand**: The combustion demand is gradually coming to an end, and the traditional peak - season logic is weakening. In the deep - processing of C4, affected by new energy substitution, the gasoline demand is weakening. The profit of MTBE is inverted, but the operating rate is high. The profit of alkylated gasoline has turned from profit to loss, and the loss of isobutane dehydrogenation profit is relatively deep. The ether - post - market may fall and stabilize. In the deep - processing of C3, the utilization rate of PDH production capacity is expected to decline. After the National Day, the operating rate may drop below 65%. The price of propylene in the intermediate link has fallen, and the terminal PP demand is saturated. The PDH device has shown continuous losses from propylene to PP, and the profit negative feedback effect has emerged [4] - **Inventory**: Last week, the factory inventory of LPG was 188,100 tons (an increase of 4.33%), and the port inventory was 3.1366 million tons (a decrease of 3.01%). The storage capacity utilization rate of the domestic LPG market increased last week. The inventory reduction in Northeast, Shandong, and Central China was relatively smooth through price concessions, but affected by adverse factors such as typhoon extreme weather and supply increase, the inventory in East China, South China, North China, and the West continued to increase. At the port, the arrival of ships decreased, and the replenishment of imported resources was insufficient [4] - **Basis and Position**: The weekly average basis in East China was 126.80 yuan/ton, in South China was 357.80 yuan/ton, and in Shandong was 301.80 yuan/ton. The total number of LPG warehouse receipts was 14,327 lots, an increase of 1,353 lots, and the lowest deliverable area was East China [4] - **Chemical Downstream**: The operating rates of PDH, MTBE, and alkylation were 69.48%, 58.35%, and 45.51% respectively. The profit of PDH to propylene was - 349 yuan/ton, the profit of MTBE isomerization was - 90 yuan/ton, and the profit of alkylation in Shandong was - 13 yuan/ton [4] - **Valuation**: The PG - SC ratio was - 2.47%, and the spread between PG continuous first and continuous second months was 79 yuan/ton. The continuous increase in crude oil production has dragged down the cost section, and the PG - SC cracking spread has continued to strengthen [4] - **Other Factors**: Crude oil is in a fundamental surplus expectation caused by geopolitical factors, sanctions, and OPEC+ production increase, and maintains range - bound trading. The non - farm payrolls data in the United States in August was lower than market expectations, with an increase in the number of unemployed people, a month - on - month decline in PPI and CPI, and economic slowdown. The Federal Reserve cut interest rates by 25bp as expected, and it is expected to cut interest rates by 50bp or more within the year. Geopolitical situations in Russia - Ukraine, US - Venezuela, and the Middle East are frequently disturbed in the short term and tend to be tense [4] 3.7 Investment and Trading Strategies - **Investment View**: The upstream PG fundamentals lack obvious drivers and tend to be weak. The supply - demand of propylene in the intermediate link is under pressure, and the short - term demand for PP is saturated with a shutdown expectation in the later period. The PDH profit is expected to decline further. Overall, in the short - term, PG prices have fallen from high levels, and the profit negative feedback effect of downstream PDH is prominent [4] - **Trading Strategy**: For unilateral trading, it is recommended to wait and see temporarily. For arbitrage, the strategies include going long on PP2601 and short on PL2601, going long on PP2601 and short on PG2601, and going long on SC and short on PG [4]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The domestic PVC market is currently in a situation of strong supply and weak demand. The export outlook is weakening, and domestic demand is flat, making it difficult to reverse the pattern of oversupply. The fundamentals are poor, and the short - term valuation has declined to a low level with limited downward space in the short term. In the medium term, attention should be paid to short - selling opportunities on rallies [11]. 3. Summary by Relevant Catalogs 3.1 Weekly Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is 2,600 yuan/ton, unchanged week - on - week; the price of Shandong calcium carbide is 2,890 yuan/ton, up 50 yuan/ton week - on - week; the price of medium - grade semi - coke in Shaanxi is 730 yuan/ton, up 50 yuan/ton week - on - week. The comprehensive profit of chlor - alkali integration continues to decline, while the profit of ethylene - based production shows a slight improvement, and the current valuation is moderately low [11]. - **Supply**: The PVC capacity utilization rate is 79%, up 2% month - on - month. Among them, the calcium carbide method is 79.3%, up 2.4% month - on - month; the ethylene method is 78.1%, up 1% month - on - month. The supply load increased last week, mainly due to the increased loads of Haohua, Jinchuan, Zhenyang, and Yinlite. It is expected to further recover next week. Although the overall maintenance volume increased in September, there were multiple new device commissionings, so the supply pressure remains high [11]. - **Demand**: In terms of exports, the final anti - dumping duty ruling in India has been announced, and China's tax rate is at a significant disadvantage compared to other countries. Once implemented, exports are expected to decline. The operating rates of the three major downstream industries decreased last week. The pipe load is 40.4%, up 1.3% month - on - month; the film load is 63.9%, down 13% month - on - month; the profile load is 38.9%, down 0.5% month - on - month. The overall downstream load is 47.8%, down 1.5% month - on - month, indicating weak overall downstream operations. The pre - sales volume of PVC last week was 759,000 tons, up 3,000 tons month - on - month [11]. - **Inventory**: Last week, the factory inventory was 318,000 tons, up 12,000 tons month - on - month; the social inventory was 971,000 tons, up 18,000 tons month - on - month; the overall inventory was 1.29 million tons, up 29,000 tons month - on - month; the number of warehouse receipts stabilized. Currently, it is still in the inventory accumulation cycle, with upstream inventory gradually shifting to the mid - stream. Under the pattern of strong supply and weak demand, the inventory accumulation is expected to continue [11]. 3.2 Futures and Spot Market No specific analysis text is provided, only multiple charts are presented, including PVC term structure, East China SG - 5 price, spot basis, 1 - 5 spread, active contract positions, trading volume, total positions, and total trading volume [16][23][25]. 3.3 Profit and Inventory No specific analysis text is provided, only multiple charts are presented, including factory inventory, ethylene - based factory inventory, calcium carbide - based factory inventory, social inventory, factory + social inventory, warehouse receipts, Shandong's comprehensive profit of purchasing calcium carbide for chlor - alkali integration, calcium carbide - based PVC profit, ethylene - based PVC profit, and Inner Mongolia calcium carbide profit [30][32][39]. 3.4 Cost Side The cost side shows that calcium carbide prices have stabilized.
