Navarro Says U.S. Refining Gap Justifies New Copper Tariffs

Former White House trade adviser Peter Navarro said the United States lacks sufficient facilities to refine copper, a shortfall he argued underscores the need for import tariffs on the metal. Navarro added that copper duties would benefit domestic producers such as Revere Copper and drew a parallel with earlier concerns over U.S. dependence on Chinese rare earths, which he said had exposed critical supply-chain vulnerabilities.
