NIMBA矿业启动转船程序，氧化铝供给变动不大

1. Report Industry Investment Rating - The rating for the alumina industry is "Oscillating" [1] 2. Core Viewpoints of the Report - The alumina supply has little change after NIMBA Mining initiated the ship transfer procedure. The alumina price has a theoretical downward space, but over - speculation is not advisable. The industry is in an over - supply stage, and a bearish approach can be taken if there is a price rebound [15] 3. Summary by Relevant Catalogs 3.1 Alumina Industry Chain Weekly Overview - Raw Materials: Domestic ore prices remained stable last week. Shanxi 58/5 bauxite was priced at 700 yuan/ton, Henan 58/5 at 658 yuan/ton, and Guizhou 60/6 at 596 yuan/ton. After the rainy season in Shanxi and Henan, some mines are resuming production, but environmental controls in the north will reduce output. The supply of domestic ore is hard to improve in the short term. Guinea ore is priced at 71 - 72 dollars/dry ton, while downstream enterprises' purchase intention is at 69 - 70 dollars/ton. NIMBA Mining has initiated a 200,000 - ton ore ship transfer, and about 1.5 million tons of port inventory is to be exported. Some inland mines in Guinea will increase shipments in November. Newly - arrived ore was 3.845 million tons, including 2.793 million tons from Guinea and 1.052 million tons from Australia. The shipping price from Guinea to China is 23.5 dollars/ton [12] - Alumina: The spot price of alumina decreased last week. The ALD northern comprehensive price was 2800 - 2860 yuan/ton, down 5 yuan/ton; the domestic weighted index was 2837.5 yuan/ton, down 33.7 yuan/ton. The import port price was 2820 - 2880 yuan/ton, unchanged. Electrolytic aluminum plants are starting winter storage, and alumina enterprises are mainly fulfilling long - term contracts. The Australian alumina is priced at about 320 dollars/ton, and the cost to northern Chinese ports is about 2828 yuan/ton, with the northern theoretical import profit dropping to about - 26 yuan/ton. The domestic full - cost of alumina is 2819 yuan/ton, and the real - time profit is 89 yuan/ton. Some enterprises' roasting was suspended due to pollution warnings, while some increased production slightly. The national alumina production capacity is 114.62 million tons, with 96.85 million tons in operation, an increase of 100,000 tons from last week, and the operating rate is 84.5% [13] - Demand: Domestically, Xinjiang Tianlong Mining stopped 27 electrolytic cells due to pollution warnings, affecting about 20,000 tons of production capacity. Xinjiang Tianshan Aluminum plans to start 60 electrolytic cells on November 21, 2025, with a production capacity of about 66,000 tons. The domestic operating capacity of electrolytic aluminum is 44.233 million tons, a decrease of 20,000 tons from last week. Overseas demand remained unchanged, with the operating capacity at 29.551 million tons [14] - Inventory: As of November 6, the national alumina inventory was 4.218 million tons, an increase of 88,000 tons from last week. The inventory of electrolytic aluminum enterprises increased, the bagged inventory of alumina enterprises decreased, the northern port inventory increased temporarily, and the inventory in other places also increased [14] - Warehouse Receipts: The registered warehouse receipts of alumina on the SHFE were 253,654 tons, an increase of 16,487 tons from last week [15] 3.2 Weekly Key Event Summaries in the Industry Chain - Rise in Australian FOB Price and Decrease in Import Profit: As of November 7, the Australian alumina price was about 320 dollars/ton, up 4 dollars/ton from October 31. The cost to northern Chinese ports is about 2856 yuan/ton, up 28 yuan/ton. The domestic market declined slightly, and the northern theoretical import profit dropped to about - 26 yuan/ton. Due to overseas production cuts and upcoming Indonesian capacity, there is still pressure on overseas alumina prices [16] - Profit and Loss of Alumina Enterprises and Production Expectations: The alumina spot price has been falling for three months. Based on the October average price, about 28.95 million tons of the total 98.25 million tons of operating capacity of 39 alumina enterprises are in full - cost loss, accounting for 29.47%. The cash - cost loss capacity is 3.45 million tons, accounting for 3.51%. Losses are mainly in enterprises in Shanxi, Henan, Shandong, and Guizhou [16] - Roasting Furnace Maintenance of an Alumina Enterprise in Hebei: Affected by environmental controls, a large - scale alumina enterprise in Hebei plans to stop 2 roasting furnaces for maintenance from 18:00 on November 3 and resume on November 8. It had stopped 2 furnaces in late October due to pollution warnings and resumed on October 31 [16] 3.3 Key Data Monitoring of the Upstream and Downstream of the Industry Chain - Raw Materials and Cost: The report provides data on domestic and imported bauxite prices, domestic bauxite port inventory, port shipments of major bauxite - importing countries, sea - floating inventory, domestic caustic soda and thermal coal prices, and alumina production costs in different provinces [17][19][23] - Alumina Price and Supply - Demand Balance: It includes data on domestic and imported alumina prices, domestic electrolytic aluminum spot price, the futures price ratio of electrolytic aluminum to alumina on the SHFE, and the weekly supply - demand balance of alumina [34][38][41] - Alumina Inventory and Warehouse Receipts: Data on electrolytic aluminum plants' alumina inventory, alumina plants' inventory, domestic alumina yard/terminal/in - transit inventory, total social inventory, port inventory, and SHFE alumina warehouse receipts and positions are presented [44][47][49]
