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. Department of the Interior's U.S. Geological Survey (USGS) has made significant adjustments to the critical minerals list, including copper for the first time since its inception in 2018, which will impact future tariff policies and trade restrictions [1][4] - The updated list includes additional minerals such as uranium, silver, metallurgical coal, potassium, rhenium, silicon, and lead, reflecting a strategic shift to reduce reliance on imports and enhance domestic production [1][4][8] - The inclusion of copper is particularly important due to its extensive applications in electrification, defense, and clean energy, with the U.S. relying on imports for nearly half of its copper consumption [5][6] Group 1 - The new critical minerals list will influence the 232 investigation announced by the Trump administration, affecting mining investments, tax incentives for mineral processing, and mining permit approval processes [4][8] - The U.S. government prioritizes increasing domestic supply of these minerals, citing national security and infrastructure development concerns due to over-reliance on foreign sources [4][5] - The list's expansion coincides with a rise in electricity demand in the U.S., driven by developments in data centers and artificial intelligence [4] Group 2 - The inclusion of potassium is aimed at addressing potential trade barriers from major supply countries, as the U.S. imports about 80% of its potassium from Canada [6][8] - The addition of silver has raised concerns among precious metal traders and manufacturers, as the U.S. heavily relies on imports to meet domestic silver demand, which could be impacted by tariffs [7][8] - The final list also includes metallurgical coal and uranium, which were not in the draft version, indicating a comprehensive evaluation of environmental factors and domestic supply conditions [8]
