From Guinea to Volkswagen's factories, the global aluminum industry is staging its own 'Game of Thrones'

By Wanlian万象

At the Sangaredi mining area in Guinea, heavy trucks shuttle through red dust, transporting bauxite to the port; meanwhile, on the production line at Volkswagen's Wolfsburg plant in Germany, robotic arms precisely press aluminum alloy sheets into car doors.

These two seemingly unrelated scenarios are closely connected through a supply chain that spans thousands of miles, playing out a global power struggle over resources, technology, and markets.

In early 2025, Guinea's bauxite exports hit a record high of 182.8 million tons, a year-on-year increase of 25%. This West African country supplies nearly 70% of the global bauxite trade but produces almost no electrolytic aluminum.

Meanwhile, China, the world's largest aluminum consumer, relies on imports for 70% of its bauxite but produces about 57% of the world’s primary aluminum. On the other side of the globe, Volkswagen plans to increase aluminum usage per vehicle by 30% by 2030, with its supply chain facing dual challenges from aluminum price fluctuations and trade barriers.

As aluminum prices continue to soar and the supply gap widens dramatically, a 'Game of Thrones' in the global aluminum industry is unfolding.

In Guinea on the west coast of Africa lies the world’s largest and highest-quality bauxite resource. This economically underdeveloped nation is quietly becoming the core of a global shift in the aluminum industry’s balance of power.

Of Guinea’s 182.8 million tons of bauxite exported in 2025, 74% went to China. Chinese aluminum companies’ investments in Guinea have formed a complete industrial chain, from mines to railways to port terminals.

But Guinea is no longer content to merely play the role of a 'raw material exporter.' In May 2025, the country’s transitional authorities announced that bauxite and iron ore mining areas would be designated as strategic reserve zones, and revoked the mining license of GAC, a subsidiary of Emirates Global Aluminium, citing unfulfilled construction commitments.

This series of actions marks the awakening of resource-rich nations. By 2030, Guinea plans to build five to six alumina refineries, increasing its local processing capacity to about 7 million tons.

The first refinery to cooperate with China's State Power Investment Corporation has commenced construction and is expected to begin operations by the end of 2027. This transformation from 'selling raw ore' to 'selling semi-finished products' represents a crucial step for resource-rich nations climbing up the global industrial chain.

At the same time, the flow of global bauxite trade is quietly being reshaped. Seventy-four percent of China’s imported bauxite comes from Guinea, a share that has increased by 20 percentage points compared to five years ago. Chinese companies are also tapping into bauxite resources in Southeast Asian countries such as Indonesia and Vietnam, but these nations’ policies are similarly shifting towards 'restricting raw ore exports and encouraging local processing.'

The rise of resource nationalism is altering the balance of power in the global aluminum industry. According to data from the International Aluminium Institute, if Guinea achieves its 2030 targets as planned, global bauxite trade volumes could decrease by approximately 5-8%, while the trading landscape for alumina will be redefined.

From bauxite to alumina, and then to electrolytic aluminum, electricity is at the core of this conversion process. The production of electrolytic aluminum is referred to as 'solidified electricity,' consuming about 13,500 kilowatt-hours per ton, equivalent to the electricity usage of an average household over 4-5 years.

As the world’s largest producer of electrolytic aluminum, China’s capacity has approached the policy-imposed 'ceiling' of 45 million tons. Since implementing the capacity replacement policy in 2017, China’s electrolytic aluminum industry has transitioned from rapid expansion to strict control, significantly slowing capacity growth.

Electricity costs have become the primary bottleneck for global expansion of electrolytic aluminum. In the United States, tech companies are paying over $100 per megawatt-hour for data center electricity, while aluminum smelters require operating electricity prices to remain below $30 per megawatt-hour to remain economical.

This competition for electricity has made it difficult for Western countries to restart or build new aluminum smelting capacities. During Europe’s 2022 energy crisis, approximately 1.5 million tons of electrolytic aluminum capacity was shut down, and most of it remains offline.

Environmental pressures are further tightening supply constraints. The EU Carbon Border Adjustment Mechanism (CBAM) will be fully implemented by 2026, requiring aluminum products entering the EU to pay carbon emission fees. China’s electrolytic aluminum production emits around 13 tons of CO2 per ton of aluminum, whereas electrolytic aluminum produced using hydropower can emit as low as 4 tons.

These structural constraints are creating a supply gap in the global aluminum market. Citi forecasts a potential supply deficit of 292,000 tons in the global aluminum market by 2026, which may widen to between 800,000 and 1.4 million tons by 2027. Bank of America research reports suggest the supply shortfall could arrive earlier and be larger than the market anticipates.

Facing an increasingly complex trading environment, participants in the global aluminum industry are moving their pieces on the board, attempting to bypass barriers and seize advantageous positions.

The US has imposed tariffs of over 400% on Chinese aluminum products, while the EU has implemented multiple anti-dumping measures. Currently, there are more than 50 trade remedy measures targeting Chinese aluminum products in effect globally.

Facing these high barriers, Chinese companies have adopted a strategy of 'indirect exports.' Mexico has become a key node in this strategy – in recent years, China’s aluminum product exports to Mexico have grown by over 40% year-on-year. Chinese aluminum companies have set up factories in Mexico to process semi-finished products into goods that comply with 'rules of origin' and then enter the US market duty-free.

Southeast Asia serves as another important springboard. Chinese companies are investing in building aluminum processing plants in Vietnam, Thailand, and Malaysia, turning primary aluminum materials into higher value-added products for re-export to Europe and America.

This restructuring of supply chains has given rise to new trade flows. The export structure of Chinese aluminum products is shifting from basic aluminum ingots to high value-added products: deep-processed items such as battery foil for new energy vehicles, high-end printing plate bases, and aerospace aluminum materials are seeing a continuous increase in proportion.

Meanwhile, China's recycled aluminum industry is developing rapidly, with production expected to reach 11.6 million tons by 2025, accounting for 20% of aluminum supply. The energy consumption of recycled aluminum production is only 5% of that for primary aluminum and is not constrained by capacity 'ceilings,' offering a new pathway to break through supply restrictions.

Technological upgrades have become another way to break through. Chinese aluminum processing companies are transitioning from 'scale competition' to 'technological competition,' achieving breakthroughs in high-end fields such as battery foil for new energy vehicles and high-performance aluminum alloys for aviation, with some products already entering mainstream international supply chains.

In this 'Game of Thrones' within the aluminum industry, there are no eternal winners, only a constantly shifting balance of power.

Resource-rich nations are striving to climb up the value chain, transforming from passive raw material suppliers into participants with pricing power and technological sophistication; producer countries are seeking technological breakthroughs and supply chain restructuring amid capacity constraints and environmental pressures; consumer countries are trying to ensure supply security through trade policies and industrial alliances.

Guinea's pursuit of local refining, China's push for the recycled aluminum industry, and the green trade barriers erected by Europe and the US may seem like isolated actions, but they all point to the same endpoint — whoever can control the complete value chain from resources to materials will take the initiative in future industrial competition.

This battle for control of the balance of power will continue.
