Strategic Shift in China's Primary Aluminum Industry

SEATTLE (Scrap Monster):  In late 2024, the Chinese government surprised global markets by rescinding export tax rebates for steel, copper, and – most notably – aluminum products. Seen by many as a proactive step to diffuse trade tensions with its major trading partners, this paper argues that the policy speaks to a broader strategy on the part of the Chinese government. Namely, to incentivize aluminum producers to focus less on exports and more on supplying fast growing sectors such as photovoltaics and electric vehicles, both of which rely heavily on aluminum inputs. Although aluminum exports have declined modestly since the policy’s implementation, it remains unclear whether increased domestic absorption will ultimately translate into greater productivity and efficiency gains across the sector.

“Ultimately, the removal of the aluminum export tax rebate reflects an effort to make production more efficient, curb excess capacity, and redirect production toward strategically important industries. While it’s too early to assess the policy’s long-term effectiveness, early evidence shows that the sector is adjusting.”

In November 2024, China’s Ministry of Finance announced the cancellation of a thirteen percent export tax rebate for aluminum, alongside similar changes for copper and other goods. For a country that produces nearly sixty percent of the world’s primary aluminum, the decision rattled domestic and global markets. London Metal Exchange (LME) prices spiked, while prices on the Shanghai Metals Market (SMM) slumped as traders anticipated a significant drop in Chinese aluminum exports. The shift raised an obvious question: why would Beijing voluntarily reduce the competitiveness of one of its major industrial exports?

Many outside observers interpreted the policy as a preemptive effort to defuse trade tensions and rein in an industry long associated with overcapacity, particularly amid expectations of escalating tariffs under a new Trump administration. Yet the underlying logic runs deeper. The rebate cancellation is better understood not as a concession to external pressure, but as part of a strategic effort to rebalance an inefficient industry. Aluminum is increasingly tied to sectors such as electric vehicles and solar power, making it central to China’s domestic industrial strategy. In this context, the removal of export rebates reflects an effort to realign incentives within the sector to better support these priorities. 

In the electric vehicle sector, a core pillar of Made in China 2025, aluminum is widely used in vehicle structures and battery systems. Battery electric vehicles contained roughly 85% more aluminum than internal combustion engine vehicles in 2022. With EVs accounting for nearly half of all car sales in China in 2024, demand from the new energy vehicle sector is projected to rise from 2 million tons in 2023 to nearly 10 million tons by 2030. Solar energy represents another major source of demand. In photovoltaic (PV) systems, aluminum is used extensively in panel frames, support structures, and mounting systems that require a combination of strength, lightweight durability, and cost-efficiency. China added 277 gigawatts (GW) of solar capacity in 2024 alone, more than double that of the United States. With each kilowatt requiring roughly 21 kilograms of aluminum, continued expansion implies substantial material demand. Together, these emerging sectors are increasingly serving as domestic outlets for aluminum production, offsetting the sector’s traditional reliance on construction and real estate. Much of this output ultimately finds its way to export markets, as EVs and solar products are exported overseas in large volume. Channeling aluminum into these industries enables China to move up the value chain by exporting higher-value manufactured goods rather than low-margin primary materials. 

Over the past four decades, China’s aluminum industry has undergone an extraordinary expansion to become the world’s largest producer and exporter. In 1983, the country produced just 400,000 tons of primary aluminum; by 2022, output had reached 40.21 million tons. This growth was fueled by government investment, low energy costs, and aggressive export incentives, including export tax rebates, which allowed exporters to reclaim value-added tax (VAT) and lower their international selling price. However, rapid expansion also created lasting structural problems. Much of the sector relied on outdated, energy-intensive production, resulting in inefficiencies and high carbon emissions due to reliance on coal-fired energy. Heavy government support and cheap bank loans further encouraged the proliferation of unproductive, loss-making “zombie companies” kept alive by local officials seeking to preserve jobs and tax revenues. 

These imbalances became more acute in the aftermath of the global financial crisis, as stimulus-driven investment led to rapid capacity expansion across heavy industry, contributing to overcapacity. Excess production was increasingly directed toward export markets, putting downward pressure on global prices and contributing to rising trade tensions. This triggered a wave of anti-dumping measures and tariffs, making sustained reliance on state-supported, export growth more difficult. In response, China shifted its approach through the supply-side structural reform (SSSR) framework. Beginning in 2016, the State Council imposed capacity limits across heavy industry, extending to aluminum with a ceiling of 45 million tons per year on primary output. This cap was reinforced by capacity replacement guidelines requiring firms to retire older, less efficient facilities before bringing new capacity online. These aluminum capacity constraints remained in place in the years that followed, limiting the possibility for another surge in over investment. 

The effects of the rebate removal are most clearly visible in export data. The market reaction to the rebate removal reflected the aluminum sector’s sensitivity to policy incentives. Immediately after its announcement in November 2024, aluminum exports surged 37% as producers rushed to ship inventory ahead of the rebate’s expiration, reaching their highest level since May 2022. However, full-year 2025 customs data show that export volume of unwrought aluminum and aluminum products declined by eight percent year-on-year. Rather than a collapse in the competitiveness of China’s aluminum exports, the decline suggests that the policy had a moderating effect. Trade flows rebalanced as incentives changed, with firms now absorbing tighter margins. 

By comparison, copper, subject to the same rebate removal in November 2024, saw a more modest decline in export volumes of six percent year-on-year, suggesting a lower sensitivity to export incentives. By contrast, China’s steel sector continues to exhibit persistent overcapacity, with exports serving as a key outlet for surplus production. Aluminum therefore occupies a middle position: like steel, it has historically been characterized by overcapacity and export dependence, but like copper, it is increasingly supported by domestic demand from emerging industries, making it more responsive to policy shifts while avoiding the sustained export pressures seen in steel. 

At the firm level, responses to the policy shift have been uneven. Margin compression has not reliably led to capacity reduction or firm exit. Instead, producers have adapted by reconfiguring production geographically, seeking lower-cost or more stable energy, and adjusting product mix. This dynamic is most evident among large producers, which can leverage scale, access to capital, and integration to absorb margin pressure and reposition production. Firms such as the China Hongqiao Group and Shandong Nanshan Aluminum have expanded operations in Indonesia, where access to lower-cost and more stable energy allows continued output growth outside China’s domestic capacity and regulatory constraints. Recent financial disclosures underscore the effectiveness of this strategy: despite a twelve percent year-on-year decline in net profit, Shandong Nanshan Aluminum’s operating cash flow rose more than thirty percent in the first three quarters of 2025, driven primarily by increased alumina revenue from its Indonesian operations. Similarly, the Aluminum Corporation of China (CHINALCO) has expanded production through a $15 billion joint venture with the provincial government of Yunnan, securing approximately 1.6 million tons of hydropower-based smelting capacity. The strategy aligns with Beijing’s goals of reducing emissions and upgrading capacity, though recurring droughts in the region have exposed the fragility of relying on renewables in an energy-intensive industry.

Smaller and less integrated producers face fewer adjustment options. Many small and mid-size firms are operating at just forty to sixty percent capacity, while others are abandoning low-margin commodity products altogether. In manufacturing hubs like Guangdong, producers have shifted away from products like window frames toward more specialized aluminum components for electronics and aerospace. These varying responses point to a partial adjustment: incentives shift, but structural overcapacity is displaced rather than eliminated. Rather than triggering widespread exit, the removal of export rebates effectively tests which firms can adapt and which remain dependent on policy support. In this sense, the policy may be implicitly accelerating consolidation, either pushing less-efficient mid-stream producers out of the market or forcing them to upgrade into higher-value segments aligned with China’s broader industrial priorities. These shifts may also have implications beyond aluminum, since gallium, a critical mineral recovered as a byproduct of alumina refining, is primarily extracted by technologically advanced, large-scale producers. 

These outcomes illustrate how, by withdrawing support for low-margin aluminum exports, Beijing is reshaping incentives toward domestic absorption and higher-value uses aligned with its industrial upgrading agenda. This approach is consistent with the priorities of Made in China 2025 and the Dual Circulation Strategy, both of which emphasize strengthening domestic supply chains and shifting away from low-margin, export-oriented production. In the aluminum sector, this has not produced immediate capacity reduction or firm exit, but rather a gradual and uneven adjustment. Similar efforts are visible in other sectors facing overcapacity pressures. In steel, Beijing continues to face persistent overcapacity despite years of state-led efforts to regulate output and restructure production capacity. In the electric vehicle sector, policymakers have similarly expressed growing concern over domestic price competition, even as EVs remain central to China’s industrial strategy. Recent reductions to photovoltaic export tax rebates also suggest a willingness to scale back support for excessive export growth in sectors tied to strategic manufacturing priorities. These developments point toward an evolving approach to industrial policy that places greater emphasis on industrial upgrading and efficiency, rather than simply maximizing output and export volume.

Ultimately, the removal of the aluminum export tax rebate reflects an effort to make production more efficient, curb excess capacity, and redirect production toward strategically important industries. While it’s too early to assess the policy’s long-term effectiveness, early evidence shows that the sector is adjusting. Large producers have taken steps to upgrade capacity through investments in lower-cost and lower-carbon energy sources, while smaller firms face tighter constraints and are less able to make similar adjustments. Additionally, exports of primary aluminum and related products have declined since the rebate’s removal. Although not the primary objective, this outcome is notable in the context of China’s strained trade relationships. The more difficult question is whether downstream industries, many of which are themselves facing overcapacity, can absorb this redirected supply. The rebate removal is one measure within a broader effort to address overcapacity and inefficiencies across China’s industrial base. What is emerging is not yet an observable reduction of capacity, but a gradual and uneven shift in how that capacity is structured and utilized.
