en.Wedoany.com Reported - The copper market enters a critical week as the U.S. tariff review deadline for refined copper approaches, with copper closing at $6.03 per pound. Washington must decide whether to impose a phased tariff on refined copper. The measure has not yet been finalized, but a preliminary recommendation suggests a 15% tariff starting in January 2027, rising to 30% in 2028.
The Donald Trump administration must assess whether to impose a universal phased tariff on refined copper. Previously, a presidential proclamation on copper imports directed the Secretary of Commerce to submit a report on the latest U.S. copper market conditions, including the country's refining capacity and the state of the refined copper market, no later than June 30, 2026. The key point is that no final decision has been made on refined copper; only a preliminary recommendation exists: if Washington deems the measure necessary to avoid national security risks, it evaluates a 15% tariff effective January 1, 2027, and a 30% tariff effective January 1, 2028.
The tariff discussion coincides with a week of falling copper prices, though prices remain at relatively high levels compared to last year. According to the latest weekly report from the Chilean Copper Commission (Cochilco), copper closed at $6.03 per pound during the week of June 22-26, 2026, down 1.8% from the previous Friday. Despite the weekly decline, the average annual price stands at $5.93 per pound, up 38.84% from the same period in 2025. Profit-taking and short-term financial pressures emerged in the market, but the price base remains favorable for producers, tax revenues, and industry profits.
Cochilco attributed the weekly decline to a stronger U.S. dollar and a relatively hawkish interpretation of the Federal Reserve's stance, which raised expectations for U.S. interest rates. This factor makes dollar-denominated commodities more expensive for buyers using other currencies, typically exerting downward pressure on industrial commodities. The agency also noted that diplomatic progress with Iran reduced oil prices and geopolitical premiums, with some of the hedging and risk-aversion momentum previously priced into the market easing this week.
The U.S. decision is critical because refined copper was previously excluded from steeper tariffs imposed on semi-finished products and derivatives with high copper content. A July 2025 proclamation imposed 50% tariffs on certain semi-finished products and high-copper-content derivatives but did not specifically define refined metal. This unresolved space now enters a decisive phase, with the White House requiring the Secretary of Commerce to report to the President on domestic copper market conditions, including U.S. refining capacity. Based on this information, Trump will decide whether to implement the recommended phased tariffs on refined copper.
For Chile, the stakes are significant. Tariffs on refined copper would alter its access conditions to the U.S. market and could affect the relative competitiveness of Chilean supply compared to other destinations or commercial structures. The impact will depend on the measure's design, such as universal application, selective measures, or the presence of exclusions, quotas, and differential treatment. Currently, these details remain undetermined.
Chile is the world's largest copper producer, and copper is central to its trade balance, fiscal revenue, and mining investment. Any major U.S. tariff change would immediately trigger industry analysis. Refined copper carries additional industrial value compared to copper concentrate, encompassing smelting and refining stages. Amid global metallurgical capacity constraints, copper concentrate supply shortages, and competition for secure supply, U.S. tariffs could prompt buyers to reassess their procurement strategies.
Cochilco warned that some factors may limit further copper price declines, including declining inventories in London and Shanghai, tight copper concentrate supply, and demand related to power grids, data centers, and artificial intelligence. Despite the weekly decline, the spot market shows signs of adjustment, with electrification, grid expansion, digital infrastructure, and energy demand from data centers underpinning copper's structural consumption base.
The tariff front is not limited to copper. The Office of the United States Trade Representative (USTR), in a statement regarding a Section 301 investigation related to forced labor, said it has surveyed 60 economies on their norms or enforcement of bans on importing forced labor products. USTR included Chile on the list of surveyed economies and proposed actions subject to public comment. For economies that have implemented or committed to implementing bans on importing forced labor products, the proposed additional tariff rate would be 10%; for others, 12.5%. The deadline for written comments is July 6, 2026, with a hearing scheduled for July 7, 2026.
This second front does not automatically equate to specific tariffs on Chilean copper, but it signals broader commercial pressure from Washington on its trading partners. For the mining sector, this is significant because critical minerals and their supply chains are increasingly influenced by national security, traceability, local content, labor standards, and regulatory compliance.
Key data include: copper weekly closing price at $6.03 per pound, weekly change down 1.8% from the previous Friday, average annual price at $5.93 per pound, and annual average price change up 38.84% from the same period in 2025. The U.S. review deadline is June 30, 2026. The measure under evaluation is a universal phased tariff on refined copper, with a preliminary recommendation of 15% from January 2027 and 30% from January 2028. Price support factors include low inventories, tight copper concentrate supply, and demand from power grids, data centers, and artificial intelligence.
The coming week will be critical to see whether the U.S. translates the refined copper review into concrete tariff measures or continues its assessment. For Chile, actual tariffs could alter the relative price, sales destinations, and commercial conditions for one of its key export products. The market will focus on the content of the Commerce Department's report, Trump's political decision, and the technical scope of any potential measures. Without a formal resolution, the impact remains potential, but risks are already factored into market analysis. If Washington moves forward with tariffs, the discussion will directly impact commercial strategies for refined copper; if delayed or moderated, prices will once again depend more on inventories, industrial demand, and copper concentrate tightness. In either case, Chile is at the center of the debate, with copper no longer viewed merely as a commodity but as a strategic input for energy, defense, digital infrastructure, and economic security.
