Copper prices hit a new record Tuesday as traders braced for possible import tariffs under Trump, according to Mining.com. The front-month contract is up 29% year-to-date, widening the price gap between the U.S. and London Metal Exchange benchmarks. Trump ordered a Commerce Department probe into copper tariffs last month on national security grounds. Goldman Sachs and Citigroup forecast 25% import duties by year-end. Mercuria estimates 500,000 tonnes are being redirected to the U.S., tightening global supply.
