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 Viewpoint - 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, which may lead to tariffs and trade restrictions on related products [1]. Group 1: Key Minerals Added - Copper has been added to the critical minerals list for the first time, marking a significant change since the list was first published in 2018 [1]. - The updated list also includes uranium, silver, metallurgical coal, potash, rhenium, silicon, and lead, replacing the 2022 version [1]. - The inclusion of these minerals aims to reduce U.S. dependence on imports and expand domestic production [1]. Group 2: Market Reactions - Following the announcement of the new critical minerals list, copper ETFs rose approximately 2%, while Southern Copper Corporation increased by 1.6%. In contrast, Freeport and McEwen saw declines of 1.2% and 1.9%, respectively [4]. - The decision on the critical minerals list will influence mining investments, recycling of mining waste, tax incentives for mineral processing, and mining permit approval processes [4]. Group 3: Strategic Importance of Copper and Potash - Copper is recognized for its strategic importance due to its applications in transportation, defense, and power network construction, especially as demand for electricity rises with the growth of data centers and artificial intelligence [5]. - The U.S. imports nearly half of its copper consumption, primarily from Chile, Peru, and Canada, with most global refining capacity concentrated in China [5]. - Potash, primarily used in fertilizer production, has been included due to potential trade barriers from major supplying countries, with about 80% of U.S. potash imports coming from Canada [5]. Group 4: Concerns Over Silver - The addition of silver to the critical minerals list 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 is widely used in electronics, solar panels, and medical devices, and any tariffs on silver could significantly impact the metal market [6]. Group 5: New Assessment Methods - A new assessment method has been introduced to evaluate the economic consequences of supply shocks and highlight vulnerabilities associated with reliance on single domestic producers [7]. - The updated list includes metallurgical coal and uranium, which were not part of the draft published in August, indicating a comprehensive evaluation process [7]. - Arsenic and tellurium have been removed from the critical minerals list due to changes in domestic production and supply risk assessments [7].
