As a new round of assessments regarding "U.S. copper tariffs" is set to conclude by month-end, market sentiment continues to heat up, driving international copper prices to fluctuate upward from elevated levels. The United States is accelerating efforts to establish an autonomous and controllable copper supply chain; through a multi-pronged approach—including anticipated tariffs, the designation of copper as a critical mineral, and expedited domestic mine approvals—it is aggressively vying for global copper resources. This strategic push is triggering a restructuring of global trade flows and pricing mechanisms. As the world's largest consumer and smelter of copper, China faces a complex landscape characterized by heavy reliance on foreign resources, widening losses in its smelting sector, and an explosive surge in demand from the new energy and high-performance computing sectors; against this backdrop, domestic spot prices continue to strengthen, and the supply-demand balance is becoming increasingly tight.
I. The Current State of U.S. Copper Resources and the Rationale Behind Tariffs
The United States possesses domestic copper reserves of approximately 47 million tons, accounting for about 5% of the global total. While its annual copper production ranks among the highest in the world, the country suffers from a severe shortage of smelting and refining capacity. Consequently, its reliance on imports for refined copper stands at a staggering 45%, making it one of the world's largest importers of refined copper. Its primary import sources are concentrated in resource-rich nations such as Chile, Peru, and Canada. Currently, the U.S. has designated copper as a priority mineral critical to national defense and the energy transition. It plans to complete a comprehensive assessment of its copper supply chain by the end of June and intends to implement a phased imposition of tariffs on refined copper starting in 2027. The core objectives of this strategy are to reduce external dependency, bolster domestic smelting capabilities, and safeguard the security of its power grid, new energy infrastructure, and high-performance computing facilities.
The underlying logic behind the U.S. drive to "secure copper" is clear:
Copper serves as an indispensable core material for new energy systems, power grids, electric vehicles, and AI data centers, with demand currently experiencing explosive growth;
Global copper mine supply growth has stagnated, high-grade ore deposits are dwindling, and frequent geopolitical disruptions have created an extremely rigid supply environment;
The strategy aims to mitigate risks associated with export controls by resource-rich nations and potential supply chain disruptions, thereby ensuring the strategic security of the U.S. low-carbon and digital economies;
By leveraging tariffs to restructure global copper trade flows, the U.S. seeks to enhance the competitiveness of its domestic industries and seize long-term pricing power over global copper resources.
II. China's Copper Resources, Production Capacity, and Supply-Demand Landscape
China possesses relatively modest domestic copper resource endowments, resulting in a long-standing reliance on foreign sources that consistently exceeds 70%. Furthermore, domestic primary copper mines typically feature lower ore grades and higher extraction costs, leaving limited scope for increasing production from within the country. Accounting for nearly 50% of global smelting capacity, China stands as the world's largest producer of refined copper; however, it remains highly dependent on imports for raw materials. In 2026, treatment and refining charges (TCs) for long-term copper concentrate contracts historically dropped to zero, while spot market TCs turned negative. Consequently, smelters are generally incurring losses on every ton of electrolytic copper produced, signaling the industry's entry into an "era of negative processing fees."
Domestic refined copper output remains at high levels; however, mounting pressure from financial losses has led to an increase in maintenance shutdowns and production cuts, significantly reducing the elasticity of supply. On the demand side, a distinct pattern has emerged: "traditional sectors remain stable, while emerging sectors are booming." Grid infrastructure investment continues to provide a solid floor for demand, and the cable industry demonstrates strong resilience in its order books. Conversely, a sluggish real estate market is dragging down copper consumption in the construction sector, while the home appliance sector—currently in its off-season—exhibits relatively weak demand. New energy vehicles (NEVs), energy storage systems, photovoltaics, and AI data centers have emerged as the primary drivers of incremental demand growth. In 2026, China's copper consumption for NEVs is projected to reach 1.84 million tons; meanwhile, copper demand from AI data centers is climbing rapidly, with orders for high-end copper materials generally booked out through 2027.
III. Domestic Spot Copper Price Trends
Since the beginning of 2026, domestic copper prices have continued to strengthen. By the end of May, spot copper prices on the Shanghai market had firmly established themselves above the 105,000 RMB/ton mark—a surge of over 14% since the end of March—reaching a multi-year high. This upward price trajectory is driven by a triple-pronged logic:
Tight supply in the mining sector and negative processing fees have led to a rigid, structural increase in smelting costs;
The continuous release of demand from the new energy and computing power sectors has resulted in consumption resilience that exceeds expectations;
Market sentiment remains strongly bullish, fueled by expectations regarding U.S. tariffs and historically low global inventory levels.
The spot market is characterized by firm premiums and tight liquidity. Spot quotes in East China consistently trade above the monthly average price, and traders are notably reluctant to sell. Downstream purchasing is driven primarily by rigid, essential demand, though the willingness to accept high prices varies across sectors: demand remains highly inelastic within the new energy and power grid sectors, whereas traditional processing enterprises are resistant to high prices, leading to the gradual emergence of substitution effects—such as replacing copper with aluminum.
IV. Global Resource Landscape and National Policies
Chile and Peru collectively account for nearly 40% of global copper mine production. In recent years, however, output from these nations has consistently fallen short of expectations due to factors such as aging mines, declining ore grades, and rising energy costs. Countries such as Indonesia, the Democratic Republic of the Congo, and Zambia have emerged as the primary drivers of incremental supply growth; however, constrained by logistics, power supply, and environmental regulations, production expansion remains sluggish and subject to high uncertainty.
Nations worldwide are actively strengthening their strategic approaches to copper resources:
Resource-rich nations are tightening export controls, raising taxes and fees on mining operations, and prioritizing the security of domestic processing capabilities.
The European Union is advancing the development of a "green copper" supply chain to reduce its reliance on external sources.
China is intensifying domestic exploration and development efforts, promoting the utilization of recycled copper, bolstering strategic reserves, and strictly regulating the addition of new smelting capacity.
The United States is accelerating the construction of an independent copper supply chain through the implementation of tariffs, subsidies, and expedited approval processes for mining projects.
The global resurgence of resource nationalism—coupled with the expectation that supply constraints will persist over the long term—provides strong fundamental support for copper prices.
V. Upstream-to-Downstream Price Transmission and Profit Dynamics Across the Value Chain
Sustained high copper prices have profoundly impacted profit distribution across the entire industry value chain:
Upstream Mining: Benefiting from high copper prices and zero-rate processing fees, upstream copper mines have seen a massive expansion in profits, emerging as the sector's biggest winners.
Midstream Smelting: Plagued by negative processing fees and inverted cost structures, smelters are experiencing widespread losses; consequently, small and medium-sized enterprises in this segment are reducing output and facing market consolidation.
Downstream Processing: This segment exhibits a distinct divergence. Traditional sectors—such as wire and cable, transformers, and electric motors—face intense cost pressures that are squeezing their gross margins. Conversely, high-end sectors—including new energy vehicles, energy storage systems, photovoltaics, and data center cooling components—demonstrate strong inelastic demand, enabling them to successfully pass on rising costs and maintain robust order books.
Rising copper prices have driven a synchronous upward trend in the prices of processed copper materials—such as copper alloys, foil, tubing, and sheet/strip products. This, in turn, has elevated the production costs of downstream end products—including power equipment, new energy machinery, home appliances, and automotive components—thereby accelerating the adoption of material substitution and technological iteration in certain sectors. VI. April 2026 Customs Import and Export Data
In April, China's copper trade was characterized by a contraction in raw material imports, refined copper imports filling domestic supply gaps, and strong resilience in copper product exports:
Imports of copper ores and concentrates totaled 2.35 million tons, a year-on-year decrease of 19%, influenced by tight overseas supply, ongoing long-term contract negotiations, and rising shipping costs;
Imports of unwrought copper and copper products reached 450,000 tons, a year-on-year increase of 3.3%, serving to fill the supply gap resulting from reduced domestic smelting output;
Exports of unwrought copper and copper products amounted to 120,000 tons, down 21.8% year-on-year, reflecting a contraction in exports amidst tight domestic supply conditions;
Exports of copper products (including wires, cables, copper plates, strips, and tubes) saw year-on-year growth, with demand from the overseas power and new energy sectors underpinning this resilience;
Scrap copper imports totaled 211,700 tons, up 3.41% year-on-year, demonstrating the role of recycled copper in supplementing primary copper supply.
Overall, these data points validate the current industry landscape: a tight balance between domestic supply and demand, a high reliance on raw material imports, and strong export competitiveness in high-end processing sectors.
VII. Outlook and Forecast
Expectations regarding U.S. tariffs continue to create market volatility. Amidst an increase in domestic smelter maintenance shutdowns and low inventory levels—coupled with steady demand from the new energy and power grid sectors—copper prices are poised to rise rather than fall. The market is expected to maintain a pattern of high-level fluctuation with an upward bias, though price swings may become more pronounced.
Driven by the global energy transition and the expansion of the digital economy, copper demand has entered a long-term growth cycle. With resource-rich nations tightening their policies and new production capacity facing constraints, copper prices are projected to remain at elevated levels over the long term. Should the anticipated U.S. tariffs officially take effect, they would reshape global copper trade flows and push up the overall cost base. Conversely, if demand from traditional industrial sectors remains sluggish, the risk of periodic price corrections may increase; however, the underlying upward trend is expected to remain intact.
