Adjusting Imports of Copper into the United States
President Trump issued a proclamation imposing a 50 percent tariff on semi-finished copper products and intensive copper derivatives imported into the United States.
This action, based on a Commerce Department report, addresses concerns about threats to national security stemming from excessive reliance on foreign copper sources and unfair trade practices.
The proclamation also outlines a process for expanding the tariff to additional copper derivatives and mandates domestic sales requirements for specific copper materials.
Future reviews of the copper market are planned to determine if additional tariffs on refined copper are necessary.
Arguments For
National Security: The proclamation argues that the current volume and circumstances of copper imports threaten US national security due to over-reliance on foreign sources, vulnerability to supply chain disruptions, and weakening of the domestic copper industry, which is essential for defense production.
Economic Stability: Imposing tariffs aims to bolster domestic copper production, creating jobs, promoting investment, and fostering innovation within the US copper industry. This would improve economic resilience and reduce reliance on foreign markets.
Fair Trade Practices: Tariffs are presented as a necessary countermeasure against unfair foreign trade practices, such as state subsidies and overproduction, which artificially depress copper prices and harm US producers.
Legal Basis: The proclamation cites the Trade Expansion Act of 1962 (section 232), which grants the President authority to adjust imports that threaten national security, as its legal justification for these actions.
Evidence: The proclamation refers to a report from the Secretary of Commerce, which provides evidence supporting the claims of threats to national security related to copper imports.
Arguments Against
Economic Impact on Consumers: The tariffs may lead to higher prices for copper-containing goods, impacting consumers and potentially hindering economic growth in sectors reliant on copper.
Retaliation from Other Countries: Other countries may retaliate with tariffs on US exports, harming US businesses and potentially leading to trade wars.
Limited Effectiveness: The tariffs might not fully address the underlying issues, such as burdensome domestic regulations or inefficiencies in the US copper industry, and could lead to substitution of materials, rather than increased production.
Supply Chain Disruptions: Implementing the tariffs could cause temporary disruptions in the supply chain, potentially impacting industries that rely on readily available copper.
Alternative Solutions: The proclamation does not fully explore alternative solutions, like targeted government support for the domestic copper sector instead of or in conjunction with tariffs. Such alternatives might facilitate a less trade-restrictive approach to strengthening national security.
1. On June 30, 2025, the Secretary of Commerce (Secretary) transmitted to me a report on his investigation into the effects of imports of copper in all forms (copper), including copper ores, copper concentrates, refined copper, copper alloys, scrap copper, and derivative products, on the national security of the United States under section 232 of the Trade Expansion Act of 1962, as amended, 19 U.S.C. 1862 (section 232). Based on the facts considered in that investigation, the Secretary found and advised me of his opinion that copper is being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States.
The Secretary of Commerce completed an investigation into the impact of copper imports on US national security.
The investigation's findings concluded that the quantity and circumstances of copper imports pose a threat to national security.
2. The Secretary found that the present quantities of copper imports and the circumstances of global excess capacity for producing copper are weakening our economy, resulting in the persistent threat of further closures of domestic copper production facilities and the shrinking of our ability to meet national security production requirements. Because of these risks, and taking into account the close relation of the economic welfare of the Nation to our national security and other relevant factors, see 19 U.S.C. 1862(d), the Secretary found that the present quantities and circumstances of copper imports threaten to impair the national security as provided in section 232.
High levels of copper imports, coupled with global overcapacity in copper production, are damaging the US economy.
This includes the threat of more domestic copper production facility closures and reduced capacity to fulfill national security needs.
The Secretary concluded these factors threaten national security.
3. In reaching this conclusion, the Secretary found that copper is essential to the manufacturing foundation on which United States national and economic security depend. Copper is the second most widely used material by the Department of Defense and is a necessary input in a range of defense systems, including aircraft, ground vehicles, ships, submarines, missiles, and ammunition. Copper also plays a central role in the broader United States industrial base. The metal’s exceptional electrical conductivity and durability also make it indispensable to critical infrastructure sectors that support the American economy, national security, and public health. Alternatives to copper are insufficient substitutes for these vital industries and products in many circumstances.
Copper is vital to US national and economic security.
It's a key component in numerous defense systems and essential to various industrial sectors and infrastructure.
Suitable replacements for copper are limited in many applications.
4. The Secretary found that the United States was a world leader across the value chain of copper production (mining, refining, semi-finished goods, and finished goods containing copper) for most of the 20th century. But despite copper being a crucial material in manufacturing and for the national and economic security of the United States, United States copper production has plummeted. Today, a single foreign country dominates global copper smelting and refining, controlling over 50 percent of global smelting capacity and holding four of the top five largest refining facilities.
The US once led the world in copper production across the entire value chain.
However, despite its importance, US copper production has significantly declined.
A single foreign nation now controls a majority of global copper smelting and refining capacity.
5. The Secretary found that unfair trade practices abroad, exacerbated by overly burdensome environmental regulations at home, have hollowed out United States copper refining and smelting, caused the United States to be overly reliant on foreign copper imports, and prevent a path forward without strong corrective action. Foreign competitors leverage state subsidies and overproduction to flood international markets with artificially low-priced copper products, driving United States producers out of business. The United States is now dangerously dependent on foreign imports of semi-finished copper, intensive copper derivative products, and copper-containing products, and imbalances in the global markets make domestic investment increasingly unviable.
Unfair foreign trade practices and stringent domestic regulations have weakened US copper refining and smelting.
Foreign competitors utilize subsidies and overproduction to undercut US prices, forcing US producers out of business.
The US now heavily relies on foreign copper imports, hindering domestic investment.
6. The Secretary found that United States dependency on foreign sources of copper is a national security vulnerability that could be exploited by foreign countries, weakens United States industrial resilience, exposes the American people to supply chain disruptions, economic instability, and strategic vulnerabilities, and jeopardizes the United States defense industrial base.
The US's dependence on foreign copper sources creates a national security risk.
This vulnerability could be exploited by foreign powers, reduces industrial resilience, and increases the risk of supply chain disruptions, economic instability, and strategic weaknesses within the US defense industry.
7. In light of these findings, the Secretary recommended a range of actions to adjust the imports of copper so that such imports will not threaten to impair the national security. For example, the Secretary recommended an immediate universal 30 percent import duty on semi-finished copper products and intensive copper derivative products. The Secretary also recommended a phased universal tariff on refined copper of 15 percent starting in 2027 and 30 percent starting in 2028. The Secretary further recommended a domestic sales requirement for copper input materials starting at 25 percent in 2027, a domestic sales requirement of 25 percent for high-quality copper scrap, and export controls for high-quality copper scrap.
The Secretary proposed various actions to mitigate the national security threat from copper imports.
These include a 30% tariff on semi-finished copper products and intensive derivatives, a phased tariff on refined copper, and domestic sales requirements for copper input materials and high-quality scrap.
8. After considering the Secretary’s report, the factors in section 232(d), 19 U.S.C. 1862(d), and other relevant factors, among other things, I concur with the Secretary’s finding that copper is being imported into the United States in quantities and under circumstances that threaten to impair the national security of the United States. In my judgment, and in light of the Secretary’s report, the factors in section 232(d), 19 U.S.C. 1862(d), and other relevant factors, among other things, I also determine that it is necessary and appropriate to impose tariffs, as described below, to adjust imports of copper and its derivatives so that such imports will not threaten to impair the national security of the United States.
The President agrees with the Secretary's findings and deems it necessary to impose tariffs to counteract the national security threat posed by copper imports.
9. To ensure that the tariffs on copper in this proclamation are not circumvented and that the purpose of this action to address the threat to impair the national security of the United States posed by imports of copper is not undermined, I also deem it necessary and appropriate to set up a process to identify and impose tariffs on certain derivatives of copper, as further described below.
To prevent circumvention of the tariffs, a process will be established to identify and tariff additional copper derivatives.
10. In my judgment, the action in this proclamation will, among other things, help increase domestic production of semi-finished copper products and intensive copper derivative products, thereby reducing our Nation’s reliance on foreign sources. It will ensure that domestic fabricators are able to supply sufficient quantities of copper products essential for infrastructure, defense systems, and advanced manufacturing. This action will also promote investment, employment, and innovation in the domestic copper fabrication sector, strengthen supply chains, enhance industrial resilience, and generate meaningful economic benefits. This action will adjust the imports of semi-finished copper products, intensive copper derivative products, and certain other copper derivatives and is necessary and appropriate to address the threat to impair the national security of the United States posed by imports of such articles.
The President believes these actions will increase domestic copper production, reduce reliance on foreign sources, improve supply chains, stimulate economic growth, and enhance national security.
11. Section 232 authorizes the President to adjust the imports of an article and its derivatives that are being imported into the United States in such quantities or under such circumstances as to threaten to impair the national security so that such imports will not threaten to impair the national security.
Section 232 of the Trade Expansion Act of 1962 provides the President with the authority to adjust imports that threaten national security.
12. Section 604 of the Trade Act of 1974, as amended, 19 U.S.C. 2483, authorizes the President to embody in the Harmonized Tariff Schedule of the United States (HTSUS) the substance of statutes affecting import treatment, and actions thereunder, including the removal, modification, continuance, or imposition of any rate of duty or other import restriction.
Section 604 of the Trade Act of 1974 allows the President to incorporate these actions into the Harmonized Tariff Schedule of the United States (HTSUS).
13. Consistent with the General Terms for the United States of America and the United Kingdom of Great Britain and Northern Ireland Economic Prosperity Deal (May 8, 2025), the United States intends to coordinate with the United Kingdom to adopt a structured, negotiated approach to addressing the national security threat in the copper sector.
The US intends to coordinate with the UK to address this copper sector issue, consistent with the US-UK Economic Prosperity Deal.
NOW, THEREFORE, I, DONALD J. TRUMP, President of the United States of America, by the authority vested in me by the Constitution and the laws of the United States of America, including section 232; the International Emergency Economic Powers Act (50 U.S.C. 1701 et seq.); section 101 of the Defense Production Act of 1950 (DPA), as amended, 50 U.S.C. 4511; section 301 of title 3, United States Code; and section 604 of the Trade Act of 1974, as amended, 19 U.S.C. 2483, do hereby proclaim as follows: (1) Except as otherwise provided in this proclamation, all imports of semi-finished copper products and intensive copper derivative products, as set forth in the Annex to this proclamation, shall be subject to a 50 percent tariff. This tariff shall be effective with respect to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern daylight time on August 1, 2025, and shall continue in effect, unless such action is expressly reduced, modified, or terminated. This tariff is in addition to any other duties, fees, exactions, and charges applicable to such imported semi-finished copper products and intensive copper derivative products, unless stated otherwise below. (2) The Secretary, in consultation with the United States International Trade Commission and U.S. Customs and Border Protection (CBP), shall determine whether any modifications to the HTSUS are necessary to effectuate this proclamation and shall make such modifications through notice in the Federal Register if needed. (3) Within 90 days after the date of this proclamation, the Secretary shall establish a process for including additional derivative copper articles within the scope of the duties of this proclamation, consistent with the processes established pursuant to Proclamation 10895 of February 10, 2025 (Adjusting Imports of Aluminum Into the United States) and Proclamation 10896 of February 10, 2025 (Adjusting Imports of Steel Into the United States). (4) The non-copper content of all copper articles subject to this proclamation shall be subject to tariffs pursuant to Executive Order 14257 of April 2, 2025 (Regulating Imports With a Reciprocal Tariff To Rectify Trade Practices That Contribute to Large and Persistent Annual United States Goods Trade Deficits), and any other applicable duties, including those imposed by Executive Order 14193 of February 1, 2025 (Imposing Duties To Address the Flow of Illicit Drugs Across Our Northern Border), as amended, Executive Order 14194 of February 1, 2025 (Imposing Duties To Address the Situation at Our Southern Border), as amended, and Executive Order 14195 of February 1, 2025 (Imposing Duties To Address the Synthetic Opioid Supply Chain in the People’s Republic of China), as amended. The additional duties described in clauses 1 through 3 of this proclamation shall apply only to the copper content of articles subject to this proclamation. CBP shall issue authoritative guidance mandating strict compliance with declaration requirements for copper content in imported articles and outlining maximum penalties for noncompliance, including that importers who submit underreported declarations may be subject to severe consequences, such as significant monetary penalties, loss of import privileges, and criminal liability, consistent with United States law. (5) If any product is subject to tariffs under both this proclamation and Proclamation 10908 of March 26, 2025 (Adjusting Imports of Automobiles and Automobile Parts Into the United States), as amended, the product shall be subject to the duties imposed pursuant to Proclamation 10908, as amended, and not those imposed pursuant to this proclamation. (6) Any product described in clause 1 of this proclamation, except those eligible for admission as “domestic status” as described in 19 CFR 146.43, that is subject to a duty imposed by this proclamation and that is admitted into a United States foreign trade zone on or after the effective date of this proclamation must be admitted as “privileged foreign” status as described in 19 CFR 146.41, and will be subject upon entry for consumption to any ad valorem rates of duty related to the classification under the applicable HTSUS subheading. (7) The Secretary shall continue to monitor imports of copper and its derivatives. The Secretary shall, from time to time, in consultation with any senior executive branch officials the Secretary deems appropriate, review the status of copper and copper derivative imports with respect to national security. The Secretary shall inform the President of any circumstances that, in the Secretary’s opinion, might indicate the need for further action by the President under section 232. By June 30, 2026, the Secretary shall provide the President with an update on domestic copper markets, including refining capacity and the market for refined copper in the United States, so that the President may determine whether imposing a phased universal import duty on refined copper of 15 percent starting on January 1, 2027, and 30 percent starting on January 1, 2028, as recommended by the June 30, 2025, report, is warranted to ensure that copper imports do not continue to threaten to impair the national security. The Secretary shall also inform the President of any circumstance that, in the Secretary’s opinion, might indicate that the duty rate provided for in this proclamation, or any actions modifying this proclamation, is no longer necessary. (8) Separately, I find that copper input materials and high-quality copper scrap meet the criteria specified in section 101(b) of the DPA, 50 U.S.C. 4511(b). Pursuant to the authority delegated to the Secretary in Executive Order 13603 of March 16, 2012 (National Defense Resources Preparedness), the Secretary shall take all appropriate action to implement the domestic sales requirements that he recommended in the June 30, 2025, report. (9) The Secretary may issue regulations, rules, guidance, and procedures consistent with the purpose of this proclamation, including to address operational necessity. (10) No drawback shall be available with respect to the duties imposed pursuant to this proclamation. (11) CBP may take any necessary or appropriate measure to administer the tariff imposed by this proclamation. (12) Any provision of previous proclamations and Executive Orders that is inconsistent with the actions taken in this proclamation is superseded to the extent of such inconsistency. If any provision of this proclamation, or the application of any provision to any individual or circumstance, is held to be invalid, the remainder of this proclamation and the application of its provisions to any other individuals or circumstances shall not be affected.
This section details the specific actions taken to address the national security threat: A 50% tariff is imposed on semi-finished copper products and derivatives effective August 1, 2025.
The Secretary of Commerce is tasked with updating the HTSUS, implementing a process to include more copper derivatives under the tariff, and monitoring copper imports for future action.
The non-copper content will also be subject to other tariffs already in place.
Any conflicts with existing tariffs and proclamations are superseded.
Finally, a review of the domestic copper market will occur by June 30, 2026 to determine if a refined copper tariff will be imposed at that time. This clarifies the specific implementation steps, ongoing monitoring, and the legal ramifications of the proclamation.
