Bauxite on the Sea Routes: China Dictates Supply and Demand
By Aluminum has long been a strategic product, and bauxite is one of the most important dry bulk commodities transported by sea and rail. Major aluminum producers shape the market and control the supply of this strategic raw material. Bauxite accounted for 4.5% of all seaborne dry bulk trade in 2025. Total seaborne bauxite exports increased by 21.6% year-on-year between January and December 2025, reaching a record 245.9 million tons, according to AXS Marine data.
Demand for bauxite bulk carriers has been steadily growing for many years. The high growth in transport in 2025 followed a 14.7% year-on-year increase in 2024 and a 3.3% year-on-year increase in 2023. Guinea is by far the largest bauxite exporter, overtaking Australia, accounting for 73.5% of the global bauxite supply in 2025.
The increased demand for bauxite is driven by growing demand for aluminum from both industrial and consumer markets. This, in turn, is driving demand for bulk terminal transshipment and dry cargo maritime transport.
Global primary aluminum production has steadily increased since 2000, with an annual growth rate of 1.06% over the long term. However, a direct comparison of current supply with data from 2000 shows that aluminum production has increased by a staggering 199% over 25 years, writes Nilanjana Banerjee, columnist for AL Circle. “This production increase has increased the scale and flow of bauxite. The seaborne bauxite trade reached a new record in 2025, reflecting the increased demand for the raw material necessary to support growing global aluminum production.”
According to data from the International Aluminum Institute (IAI), bauxite mine shipments reached an estimated 246.6 million tons in 2025, as calculated by brokers Ursa Shipbrokers. This means that bauxite mines delivered almost 42 million tons more bauxite to the market than in 2024, a 21% increase year-on-year. This increase clearly illustrates the growing demand for bauxite supplies (primarily seaborne).
Compared to 2016 volumes of approximately 78.5 million tons, global bauxite supplies have increased at an approximate compound annual growth rate of almost 14%, according to Nilanjana Banerjee. Demand and traffic on maritime routes have been driven primarily by China’s economy. Over the past 25 years, the country has become increasingly dependent on imported ore to power its production plants.
China and the EU on the Bauxite Sea Route
In terms of imports, China’s processing plants were by far the largest recipient of bauxite in 2025. This market accounted for 81.6% of global bauxite imports. Imports to China increased by 15.4% year-on-year in 2025 alone, reaching 192.1 million tons. This is a remarkable annual increase, considering that 166.4 million tons of bauxite were unloaded at bulk terminals in 2024. This is almost twice as much as in 2021, when bulk carriers delivered 112.9 million tons of imported bauxite to Chinese ports.
Outside of China, the European Union was the largest importer. However, EU countries account for only 9.2% of global bauxite demand. The increase in demand was impressive, likely driven by the defense, aerospace, and aviation industries. Imports to the EU increased by 108.1% year-on-year to 21.7 million tonnes in 2025. This was almost three times more than recently assumed, explain Banchero Costa Research analysts, reminding that in 2023 the EU unloaded only 7.7 million tonnes of bauxite in ports.

Bauxite is important for EU countries because “The European aluminum industry alone is a major exporter, and the five largest markets for aluminum products – the United Kingdom, the United States, Switzerland, Turkey, and India – generate exports worth over €10 billion. Our 44 preferential agreements with 76 countries are key to Europe’s trade success, covering 46% of our trade,” said Commissioner Maroš Šefčovič, responsible for Trade and Economic Security, to attendees of the European Aluminum Summit 2025.
The third largest market driving demand for bauxite is India, with a 2.1% share. Last year, Indian industry only required 4.9 million tons of bauxite. The United Arab Emirates is the fourth largest market, with a demand for 4.1 million tons in 2025. This represented only a 1.7% share of global imports.
Guinea on a Bauxite Mountain
For bauxite, bulk carriers most frequently docked at Guinean ports between January and December 2025. Here, bauxite shipments rose to 182.8 million tons, according to official Reuters data, strengthening Reuters’ dominant position in aluminum ore supplies, reports Maxwell Akalaare Adombila, Ruters’ Dakar correspondent. This was a 25.5% increase year-on-year, as 144.1 million tons of bauxite were loaded onto ships in Guinea between January and December 2024. In 2025, bauxite exports from Guinea were almost twice as high as the 101.2 million tons exported in 2022, according to analysts at Banchoero Costa Research.
Guinea has overtaken Australia to become the world’s largest bauxite exporter in 2023, according to data from strategic commodities research firm BMI, part of the Fitch Solutions group. Guinea’s mines have been consistently recording double-digit production growth for some time now. Data from the Guinea Ministry of Mines shows that 23 companies are exporting bauxite in 2025.
China’s Chalco (601600.SS) leads the export rankings with 22.1 million tonnes loaded onto ships. CBG, a company majority-owned by a consortium comprising mining companies Rio Tinto (RIO.L) and Alcoa (AA.N), followed with 17.4 million tonnes. SMB (the first private bauxite exporter) and the largely Guinean-owned joint venture AGB2A/SDM each shipped 17 million tonnes, a Reuters correspondent reports.
Simandou – a mountain of iron and bauxite
Bauxite exports slowed in the second half of the year, but overall they still increased by 16% to 84 million tons. China remains the main beneficiary of the Guinean mining boom. Chinese operators control over 60% of the massive investment in the Simandou iron ore mine. The investment, worth over $20 billion, has triggered the largest investment in the global mining industry. After years of delays, the mine began operations in December 2025, according to International Services Shanghai.
This is the largest mining investment in the world, encompassing a mine with a high iron content (over 65%) and all logistics from the mine to the loading terminals. The logistics include a 600-kilometer railway line and a port, reports Semafor. British-Australian mining giant Rio Tinto and Chinese company Baowu Steel are among the companies that have partnered with the Guinean government on the $15 billion project.
The Chinese operator began operating the mine last year. It also holds stakes in gold and lithium mining and processing projects. A Citi note shows that by November 2025, Guinea had shipped 150 million tons of bauxite to China – over 80% of the raw material Beijing needs to produce 45 million tons of aluminum at its domestic smelters, Reuters reports.
Australia ranked second, accounting for 18.6% of the global bauxite supply in 2025. Between January and December of last year, bauxite exports from Australia increased by 3.2% year-on-year to 45.8 million tons. This followed a strong 2024, when Australia’s exports increased by 12.8% year-on-year. Brazil ranked a distant third, with a mere 2.6% share of the global market. Exports from Brazil increased by 37% year-on-year in 2025, reaching 6.4 million tons.
Iron ore from the Simandou Mountains and deposits is exported from Guinea via the new Morebaya deepwater port. The ore is transported from the Simandou Mountains over 600 km via the Trans-Guinean Railway. Australia exports the raw material primarily from the bulk terminals in ports in Queensland and the Northern Territory. Exports, primarily to China, are carried out by conveyor belt through dedicated export terminals in Gove Port (NT), Weipa (QLD), and Gladstone (QLD).
The largest bauxite unloading ports in China in 2025 were: Yantai New West Port (33.3 million t in January-December 2025), Fangcheng (31.2 million t), Yantai (25.2 million t), Qingdao (18.9 million t), Caofeidian (12.9 million t), Huanghua (11.7 million t), Longkou (10.5 million tons), Tianjin (9.3 million tons).
70.3% of bauxite transported by sea to China in 2025 was loaded on Capesize ships. Hence the high demand for these bulk carriers. Only 7.4% of bauxite was delivered to China by VLOC bulk carriers, 14.3% was transported in Post-Panamax or Baby-Cap holds, 5.4% was discharged from Panamax/Kamsarmax vessels and 2.4% from Supramax vessels.
