美国正式公布新版关键矿产清单：首次纳入铜，银铀钾肥也入列

Core Points - The U.S. government has made its largest adjustment to the critical minerals list since its inception, directly impacting the Section 232 investigation announced by the Trump administration in April, which may lead to tariffs and trade restrictions on related products [1] - The updated list now includes copper, uranium, silver, metallurgical coal, potash, rhenium, silicon, and lead, marking a significant change from the 2022 version [1] - This adjustment aims to reduce U.S. reliance on imports and expand domestic production, as stated by U.S. Secretary of the Interior Doug Burgum [1] Group 1 - The inclusion of copper and potash addresses supply chain risks, with copper being crucial for electrification, defense, and clean energy [4][5] - The U.S. imports nearly half of its copper consumption, primarily from Chile, Peru, and Canada, while most global copper refining capacity is concentrated in China [5] - Potash, used mainly for fertilizer production, is largely imported from Canada, with 80% of U.S. usage coming from there [5] Group 2 - The addition of silver has raised concerns among precious metal traders and manufacturers reliant on the material, as the U.S. heavily depends on imports to meet domestic silver demand [6] - Silver's inclusion is a response to potential supply disruptions from Mexico, with the U.S. Geological Survey (USGS) categorizing minerals by risk levels for the first time [6] - The new assessment method considers economic consequences of supply shocks and highlights vulnerabilities from reliance on single domestic producers [6] Group 3 - Metallurgical coal and uranium were added to the final list despite not being included in the draft published in August, indicating a comprehensive evaluation process [7] - Metallurgical coal is essential for steel production, while uranium serves as fuel for nuclear power plants [7] - The USGS removed arsenic and tellurium from the critical minerals list due to decreased supply disruption risks and increased domestic production [7]
