1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The alumina market remains weak due to supply pressure. Although the procurement activity of electrolytic aluminum enterprises has increased, the downstream buyers are pressing down prices severely due to the oversupply of alumina, and the consumption increment is limited. The warehouse receipt inventory continues to rise, adding pressure to the market. Attention should be paid to the cost support of alumina [2][7]. 3. Summary According to Relevant Catalogs Transaction Data | Category | 2025/9/5 | 2025/9/12 | Change | Unit | | --- | --- | --- | --- | --- | | Alumina Futures (Active) | 3006 | 2914 | -92 | Yuan/ton | | Domestic Alumina Spot | 3166 | 3099 | -67 | Yuan/ton | | Spot Premium | 202 | 224 | 22 | Yuan/ton | | Australian Alumina FOB | 355 | 333 | -22 | US dollars/ton | | Import Profit and Loss | -1.30 | 123 | 124.3 | Yuan/ton | | Exchange Warehouse Inventory | 112306 | 138692 | 26386 | Tons | | Exchange Factory Warehouse | 0 | 0 | 0 | Tons | | Bauxite (Shanxi, 6.0≤Al/Si<7.0) | 600 | 600 | 0 | Yuan/ton | | Bauxite (Henan, 6.0≤Al/Si<7.0) | 610 | 610 | 0 | Yuan/ton | | Bauxite (Guangxi, 6.5≤Al/Si<7.5) | 460 | 460 | 0 | Yuan/ton | | Bauxite (Guizhou, 6.5≤Al/Si<7.5) | 510 | 510 | 0 | Yuan/ton | | Guinea CIF | 74.5 | 74.5 | 0 | US dollars/ton | [3] Market Review - Alumina futures' main contract fell 3.06% last week, closing at 2914 yuan/ton. The national weighted average price of the spot market was reported at 3099 yuan/ton on Friday, a decrease of -67 yuan/ton from the previous week [5]. - In the bauxite market, the overall supply of domestic ores remains severe. The regular inspections and the slow resumption of closed mines have kept the operating rate of inland mines low, with limited spot circulation in the market, which supports the price. The inventory of imported ores at Chinese ports has started to decline, but the overall supply of imported ores in China is still slightly excessive. Enterprises will continue to make purchases based on rigid demand in the short term, and the differences in price views between supply and demand sides will lead to continued price competition in the market [5]. - On the supply side, alumina supply increased slightly. Some alumina enterprises in the north that were affected by environmental protection measures and reduced production have slightly increased production this week. As of September 11, China's alumina production capacity was 114.8 million tons, the operating capacity was 95.7 million tons, and the operating rate was 83.36% [5]. - On the consumption side, last week, the electrolytic aluminum production capacity in Shandong was transferred to Yunnan, while other electrolytic aluminum enterprises maintained stable production. Overall, the operating rate of the electrolytic aluminum industry remained stable compared with the previous week, and the demand for alumina did not change significantly [5]. - In terms of inventory, the warehouse receipt inventory of alumina futures increased by 11,000 tons last Friday, reaching 139,000 tons, while the factory warehouse inventory remained at 0 tons [2][5][7]. Market Outlook - The Chinese bauxite market showed no significant changes last week. The interaction of multiple bullish and bearish factors led to no substantial adjustment in prices. On the supply side, some previously shut - down production capacities resumed operation last week, resulting in a slight increase in operating capacity. On the consumption side, the procurement activity of electrolytic aluminum enterprises increased significantly compared with the previous period. However, due to the oversupply of alumina, downstream buyers are pressing down prices severely, and the procurement is mainly for rigid demand replenishment, with limited consumption increment. The warehouse receipt inventory continued to increase by 11,000 tons during the week, reaching 139,000 tons, while the factory warehouse inventory remained at 0 tons. Overall, the operating capacity of alumina remains at a high level, and considering the current weighted average cost of alumina, there is still some profit. It is expected that the operating capacity of alumina will remain high in the future. The consumption side remains stable, and with sufficient supply, buyers have a strong mindset of pressing down prices. The rising warehouse receipt inventory also adds pressure, so alumina will continue to be weak, and attention should be paid to the cost support of alumina [2][7]. Industry News - Vedanta announced an investment of over 125 billion rupees to enhance its metal manufacturing capabilities, aiming to strengthen the domestic supply of key materials necessary for electric vehicle production to meet the needs of India's rapidly growing electric vehicle (EV) industry and contribute to India's vision of sustainable and clean transportation. The investment involves expanding the aluminum smelting business, increasing the added value of aluminum products, building a new zinc alloy factory, installing a zinc roasting furnace, and expanding the ferrochrome production capacity [8]. - Jiaokou County Wangzhuang Pig Iron Co., Ltd. won the exploration right of the Fengjiagang block bauxite in Jiaokou County, Shanxi Province, with the highest bid of 3.1728 billion yuan [8]. - Metro Mining's operating data for August 2025 showed that the shipment volume of its Queensland bauxite mine project increased by 6% year - on - year to 753,101 wet tons. As of now, Metro Mining's total bauxite shipment volume has reached 3.4 million wet tons, and its target shipment volume for 2025 is 6.5 - 7 million wet tons [8].
