The Global Copper Industry Is Facing A Major Transformation: The Supply Chain Game And Price Storm Behind The US Export Restriction Proposal.

Introduction: The global copper market is undergoing an unprecedented supply chain reconfiguration. American copper giants such as Rio Tinto and Southline have suddenly called on the government to restrict the export of copper concentrate and scrap copper instead of imposing import tariffs. If this abnormal suggestion is adopted, it will completely overturn the decades-long copper trade pattern between China and the United States. As the world's largest supplier of scrap copper, the United States exports approximately 600,000 tons of scrap copper to China each year, accounting for a significant proportion of China's total imports. This policy shift may not only trigger a "food shortage" crisis for Chinese smelters, but also ignite the fuse for a new round of global copper price hikes.
I. Policy Shift: From Tariff Sticks to Export Blockades
The "abnormal" suggestions of industry giants: The U.S. Section 232 copper tariff investigation was originally intended to protect domestic industries by imposing additional import tariffs, but copper industry giants such as Rio Tinto and South Line have proposed "reverse operations" of restricting exports. The motivation behind this suggestion is intriguing: • Seizing global copper inventories: The United States is expected to attract global copper inflows through high tariffs. The COMEX copper price is at a 14% premium over the LME, which has spurred traders to transport copper from London to the United States, leading to a sharp increase in copper inventories in the US and tight supply in other regions. • Passing on cost pressure: The decline in global copper mine grades, the delay of new projects (such as the shutdown of the Tromoc copper mine in Peru due to environmental issues), coupled with the surging demand for new energy, have put huge pressure on copper prices to rise in the long term. Restricting exports can push up international copper prices and relieve the cost pressure on US smelters.
2. China's "Scrap Copper Dependence Syndrome" China's copper smelters' reliance on scrap copper from the United States far exceeds expectations: • Historical dependence: At its peak, scrap copper from the United States accounted for nearly one-third of China's imports, and for some factories, over 70% of their raw materials came from the United States. • Short-term shock: If exports are restricted, China will face a shortage of at least 600,000 tons of scrap copper per year. Although they have shifted to Southeast Asia, Chile and other places, supply chain adjustments will take time, and small and medium-sized enterprises may be forced to reduce production. • Long-term transformation: China's scrap copper recycling rate has ranked among the top in the world, but it is difficult to fill the gap in the short term. This crisis may accelerate the upgrading of the domestic recycling system and promote the transformation of the copper industry towards self-sufficiency.
Ii. Price Storm: The "powder keg" of the global copper market is about to explode
The contradiction between supply and demand continues to escalate. On the supply side: The global copper gap is expected to reach 500,000 to 1 million tons in 2025. The decline in copper ore grade (such as the historical strike at the Escondida copper mine in Chile), the delay of new projects (such as the limited short-term increment of the Kamoa-Kakura project in Congo), coupled with ESG constraints (water resource restrictions, community protests), has significantly lagged behind the growth rate of supply. • Demand side: The new energy revolution is accelerating copper consumption. The International Energy Agency (IEA) predicts that the annual demand for copper will increase to 30 million tons by 2030, an increase of nearly 50% compared with 2025. China's power grid investment increased by 27.7% year-on-year. The fixed asset investment of China Southern Power Grid is expected to reach 175 billion yuan in 2025, and the demand for copper continues to rise.
2. Market Premium and Arbitrage Frenzy • Comex-LME Spread Soaring: COMEX copper prices have risen by more than 27% this year, with a premium of $1,200 per ton over LME, reaching a historical high. Traders engaged in frantic arbitrage, transporting copper from Asia to the United States, which led to a sharp decline in LME's Asian warehouse inventories, with nearly 50% of warehouse receipts being cancelled. • Regional supply imbalance: The "copper rush" in the United States has led to a shortage of refined copper in other regions. The premium of copper imports in Southeast Asia has risen to an 11-month peak, while inventories in Europe have declined simultaneously. The global supply chain is facing the risk of regional disruption.
Iii. The Scrap Copper Industry in the United States: From a "hot commodity" to a "Hot potato"
1. The counterproductive effect of export restrictions • Inventory crisis: The export of scrap copper from the United States has nearly come to a standstill, and the inventory backlog is severe. After losing China, the largest buyer, small enterprises are facing a survival crisis and some or some are forced to withdraw from the market. • Price disadvantage: Due to high labor and environmental protection costs, the international competitiveness of scrap copper from the United States has declined. Even if exports are restricted, it is difficult to digest domestic inventories. Large enterprises may integrate the market through mergers and reorganizations.
2. Opposition from industry associations: The American Recycled Materials Association emphasizes that the domestic supply of scrap copper is abundant, and restricting exports will undermine trade freedom. However, the data reveals a contradiction: In January 2025, the export volume of recycled copper from the United States decreased by 14.31% month-on-month, while China remained the largest buyer (23,200 tons). The differences in interests within the industry have become prominent, and policy games have continued to heat up. Iv. Global Copper Trade Pattern: From "US-Centered" to "Multipolar" \ n1. China's Supply Chain Reconstruction • Diversified Imports: Accelerate the expansion of waste copper sources in Southeast Asia, Australia, etc., and reduce reliance on the United States. • Technological upgrade: Enhance the efficiency of domestic waste copper recycling and promote the green transformation of the industry. By 2025, the proportion of recycled copper may reach 20%, partially easing the supply pressure.
