On Tuesday local time, U.S. President Donald Trump once again wielded the tariff baton, opening a new "front" in global trade tensions. Trump signed an executive order directing the U.S. Secretary of Commerce to launch a "232 investigation" into copper imports, a move that could lead to tariffs on copper. This action aims to revitalize domestic copper production in the U.S. and reduce dependence on external supply.
The "232 investigation" is conducted under Section 232 of the 1962 Trade Expansion Act, authorizing the U.S. Department of Commerce to investigate whether the import of specific products threatens U.S. national security. If the investigation finds that these products indeed pose a threat, the government can impose tariffs and other measures to restrict imports.
The Importance of the Copper Industry
As an essential industrial metal, copper is crucial for various industries, including electric vehicles, military equipment, semiconductors, and consumer goods. Being the world's largest economy, the U.S. has seen increasing demand for copper in recent years, but domestic production has not kept up with demand, leading to growing reliance on imported copper. The White House believes that imposing tariffs on copper will help promote domestic production, reducing dependency on external copper resources.
U.S. Secretary of Commerce Howard Lutnick stated in a declaration: "Just like our steel and aluminum industries, our great American copper industry has been hit by competition from global participants. American industry and defense rely on copper, and 'copper should be made in America, with no exemptions, no exceptions.' It's time to bring copper back."
Trade Protection Measures and Tariff Preferences
White House trade advisor Peter Navarro indicated that the copper import investigation will be completed soon. White House officials stated that any potential tariff rates will be determined by the investigation results, emphasizing that Trump prefers implementing trade protection measures through tariffs rather than quotas.
This investigation will focus on imported copper ores, concentrates, alloys, scrap, and derivative products. The White House believes that as demand for electric vehicles and artificial intelligence grows, the U.S. might face a copper shortage unless the industry receives long-term trade protection, making it difficult for the U.S. to develop adequate smelting and refining capabilities.
Potential Impact
According to data from the U.S. Census Bureau, Chile, Canada, and Mexico are the largest suppliers of refined copper and copper products to the U.S. in 2024, making these three countries the primary countries affected by potential copper tariffs. This move by the Trump administration could significantly impact copper exports from these countries.
Since taking office, Trump has repeatedly threatened to impose tariffs. Earlier this month, he announced a 25% tariff on imported steel and aluminum and directed relevant departments to take "reciprocal tariff" measures against all foreign trading partners. Last week, Trump also suggested considering tariffs of 25% or higher on cars, semiconductors, and pharmaceuticals. This Monday, he confirmed plans to proceed with tariffs on Mexico and Canada as scheduled.
Trump's tariff policy has drawn widespread attention both domestically and internationally, creating uncertainty in the global trade landscape and supply chains. While supporters believe this is a necessary measure to protect domestic industries, critics worry that the policy might trigger trade friction and raise production costs.
