On September 28, Freeport-McMoRan fell 3.89% in regular trading, trading at $69.665/share, with turnover of $36.54 million. The decline came as the copper sector broadly sold off amid heightened uncertainty over U.S. refined copper tariff policy.

September 28 marks the legal deadline for the White House to decide whether to impose staged tariffs on refined copper — 15% beginning January of next year, escalating to 30% the following January — following a 90-day review period after the Commerce Department submitted its market review report on June 30. The policy uncertainty has weighed on copper equities and futures alike. Earlier this month, reports that the White House had not yet made a decision on refined copper tariffs triggered a sharp sell-off in COMEX copper futures and copper mining stocks, with Freeport-McMoRan dropping over 7% in a single session on September 10.

Within the Copper sector, stocks were broadly under pressure. Southern Copper Corp fell 3.15%, Ero Copper fell 4.11%, TREKOR METALS fell 3.31%, while Idaho Copper Corporation rose 1.95%.
