Copper, the industrial metal leader, will be used by President Donald Trump as a negotiating tool.

“I am announcing a 50% TARIFF on Copper, effective August 1, 2025, after receiving a robust NATIONAL SECURITY ASSESSMENT. 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! Why did our foolish (and SLEEPY!) ‘Leaders’ decimate this important Industry? This 50% TARIFF will reverse the Biden Administration’s thoughtless behavior, and stupidity. America will, once again, build a DOMINANT Copper Industry. THIS IS, AFTER ALL, OUR GOLDEN AGE!” Trump posted on Truth Social late Wednesday.
