US Copper Tariffs in Limbo as Prices Plummet

Copper prices plummeted by 4.48% on Thursday to close at $14,169 after reaching an all-time high of $14,854 on September 9.

The sharp drop was triggered by changes in U.S. refined copper tariff policy, which had previously been expected to impose a 15% tariff on refined copper imports starting in 2027 and raise rates further thereafter.

However, according to a Reuters report on September 10, the White House has not yet made a final decision on refined copper tariffs, with concerns over affordability and manufacturing costs delaying the policy decision.
