China's Aluminium Industry Profit Surges Past RMB 5,000/Tonne in October: An In-Depth Analysis of Driving Factors

October 2025 marked a significant milestone for the Chinese aluminium industry, as the average profit per tonne of primary aluminium surpassed the RMB 5,000 threshold for the first time, reaching an impressive RMB 5,022/tonne. This represents a substantial improvement over previous months and reflects a powerful combination of reduced production costs and increased market prices. This in-depth news report will analyze the key factors behind this exceptional performance, while also offering insights into future prospects and challenges.

Detailed Analysis of Profit Performance

According to data from SMM (Shanghai Metals Market), the average profit of RMB 5,022/tonne in October 2025 indicates a robust recovery for the industry. Notably, 100% of the operating capacity of aluminium smelters in China, estimated at approximately 44.05 million tonnes, were profitable during this period. This demonstrates the high stability and adaptability of manufacturers amidst fluctuating market conditions.

1. Production Cost Reduction:

A primary driver for the surge in profitability came from effective cost control and reduction. The average tax-inclusive full cost for the Chinese aluminium industry in October was RMB 15,889/tonne. This figure represents a 1.8% decrease month-on-month and a more significant 13.3% reduction year-on-year. The key factor contributing to this cost decline was a substantial drop in alumina prices – the most critical raw material input.

• Falling Alumina Prices: The average alumina price in October fell to RMB 2,938/tonne, a decrease of RMB 175/tonne compared to September. This resulted in a 5.5% drop in the weighted average alumina cost for the industry. A surplus in both domestic and international alumina markets created downward pressure on prices, providing a significant advantage to aluminium producers.

2. Rising Finished Aluminium Prices:

Parallel to cost reductions, the price of finished aluminium in the market also saw a strong upward trend, further bolstering profit margins for enterprises.

• Spot Price Increase: The average spot price for SMM A00 primary aluminium in October reached approximately RMB 20,911/tonne. This price level maintained its growth momentum, reflecting stable demand and tightly controlled supply.
• Global Aluminium Prices Hit 3-Year High: In the international market, aluminium prices also surged, reaching nearly $2,920/tonne in early November 2025, the highest level in the past three years. This trend was supported by macroeconomic factors and production restriction policies in China.

Key Driving Factors

This profit boom is not merely a result of raw material price fluctuations but also a consequence of a series of long-term policies and market trends:

• Supply-Side Reforms and Production Caps: The Chinese government continues to implement supply-side reforms, including imposing production caps on primary aluminium. The output ceiling for 2025 is maintained at around 45 million tonnes, aiming to control overall supply and promote sustainable industry development. This has helped tighten supply, pushing prices higher.
• Energy Consumption Controls and Environmental Policies: Strict energy consumption control measures and environmental protection policies have restricted the operations of aluminium smelters, especially less efficient ones. This not only reduces pollution but also contributes to reducing excess supply in the market, creating conditions for aluminium price growth.
• Alumina Market Surplus: As mentioned, the global alumina market surplus has significantly reduced raw material costs for aluminium producers, creating a major competitive advantage.
• Stable Demand: Despite concerns about global economic growth, demand for aluminium remains stable, particularly from industries such as automotive, construction, and packaging, as well as the growing development of aluminium applications in green energy.

Outlook and Challenges

The strong performance in October 2025 sends positive signals for the Chinese aluminium industry. However, investors and experts should consider the following factors:

• Sustainability of Alumina Prices: Will alumina prices continue to remain low, or will there be an adjustment as demand picks up or supply tightens? Raw material price volatility is always a potential risk.
• Environmental and Energy Policies: Energy and environmental control policies may continue to tighten, affecting operating costs and the expansion capabilities of smelters. This could lead to producers needing to invest in cleaner and more efficient technologies.
• Global Demand Fluctuations: The global economic situation, especially in major consuming markets, will continue to influence aluminium demand and prices. Any economic downturn could put pressure on prices.
• Investment Opportunities: With attractive profit margins, the Chinese aluminium industry may attract further investment in advanced production technologies, process optimization, and the development of high-value-added aluminium products. Investors can also look for opportunities across the supply chain, from bauxite mining to the production of aluminium coil and sheet pricing and specialized aluminium alloys.

Conclusion

October 2025 was a remarkably successful month for the Chinese aluminium industry, with average profits exceeding RMB 5,000/tonne. The combination of reduced raw material costs (especially alumina) and higher finished aluminium prices, coupled with effective supply-side control policies, has created a robust financial picture. While potential challenges remain, the outlook for China's aluminium industry is largely positive, especially as what is aluminium and its role become increasingly vital in modern industries and sustainable development trends.
