Commerce deadline on refined copper passes with no public ruling

The Commerce Department's update on US copper markets was due June 30, 2026, and was the input for a presidential decision on a phased refined-copper duty. As of mid-August reporting no public ruling had been issued, and the market kept pricing a 15% tariff from January 2027. Refined copper imports stayed duty-free while buyers kept stockpiling in the US.
