The decision was made after he received a national security assessment, Trump said in a post on Truth Social.
“I am announcing a 50% TARIFF on Copper, effective August 1, 2025, after receiving a robust NATIONAL SECURITY ASSESSMENT,” Trump wrote.
“Copper is necessary for Semiconductors, Aircraft, Ships, Ammunition, Data Centers, Lithium-ion Batteries, Radar Systems, Missile Defense Systems, and even, Hypersonic Weapons, of which we are building many. Copper is the second most used material by the Department of Defense.”
Copper prices rose 2.62%, following Trump’s latest announcement, extending its gains from the previous session when it jumped 13.12% and recorded its best one-day gain since 1989.
Meanwhile, the three-month benchmark copper futures on the London Metal Exchange was down 1.63% at $9630.50 a ton as of 9.20 a.m. Singapore time, a reflection of the unusually wide premium that’s developing between U.S. copper and the metal elsewhere.
U.S. copper prices spiked on Trump’s 50% tariff announcement
According to London-based agency Benchmark Mineral Intelligence, U.S. consumers could be paying around $15,000 per metric ton for copper, while the rest of the world pays around $10,000 by August.
Adam Whiteley of BNY Investments said on CNBC’s “Squawk Box” that Trump’s latest announcement is indicative of the trade policy that he wants to protect.
“Copper is probably in a third category of tariffs, which is national security. So we’ve got negotiating tactics, we’ve got addressing trade imbalances, and then the copper, or indeed, any of the minerals, maybe semiconductors, maybe pharmaceuticals,” Whiteley said.
Copper is the third-most-consumed metal globally, behind iron and aluminum. The U.S. imports nearly half of the copper it uses, most of which comes from Chile, according to data from the U.S. Geological Survey.
British multinational research firm BMI expects global copper mine production to increase at an average annual rate of 2.9% from 2025 to 2034, with annual output rising from 23.8 million metric tons in 2025 to 30.9 million metric tons by 2034.
For this year, the firm’s analysts expect global copper mine output to rise by 2.5% year over year in 2025, supported by recovering production in Chile and the ongoing ramp-up at the Oyu Tolgoi mine in Mongolia.
Peru, Russia and Zambia are also expected to be among the major contributors to the rise in global output, the analysts wrote in a Jul. 9 note.
Earlier on Tuesday, U.S. Commerce Secretary Howard Lutnick told CNBC’s “Power Lunch” that the Trump administration wants to bring “copper production home.” He noted that Trump’s move will bring copper tariffs in line with U.S. duties on imports of steel and aluminum, which Trump doubled to 50% in early June.
However, experts say that this will take a while before production ramps up, and possibly decades to fulfill demand.

In late February, Trump ordered a probe into potential new tariffs on copper imports on national security grounds.
