US President Donald Trump has signed an executive order directing the US Department of Commerce to examine possible copper tariffs, the latest in a string of measures aimed at imposing sector-specific levies that could reshape global supply chains.
Trump said the order would have a “big impact” as he signed it in the Oval Office, joined by US Secretary of Commerce Howard Lutnick.
Senior administration officials earlier on Tuesday cast the step as necessary to address what they said was a national security issue. They argued that dumping and overcapacity in world markets had impacted domestic US copper production, leaving weapons systems and other critical products dependent on imports.

The officials, briefing reporters on condition of anonymity, said it was premature to discuss a potential rate for the tariffs.
Copper is a critical material for modern economies because of its widespread use in the wiring that delivers electricity to homes and factories. Many analysts forecast higher prices this decade, as supply fails to keep pace with demand. As with other metals, China’s grip is particularly strong when it comes to processing — the country accounted for about 44 percent of the world’s refined copper last year, according to the US Geological Survey.
The investigation would be carried out under Section 232 of the Trade Expansion Act, which gives the US president broad authority to impose trade restrictions on domestic security grounds.
Trump is also employing that authority to impose 25 percent tariffs on two other industrial metals — steel and aluminum — with those levies slated to take effect next month.
Lutnick said in a statement that the action would also probe products that include copper, and said the administration aimed to rejuvenate the domestic copper industry.
“Like our steel and aluminum industries, our great American copper industry has been decimated by global actors attacking our domestic production,” Lutnick said. “Tariffs can help build back our copper industry, if necessary, and strengthen our national defense.”
Peter Navarro, a Trump trade adviser, singled out China, saying it had “long used industrial overcapacity and dumping as an economic weapon to dominate global markets, systematically undercutting competitors and driving rival industries out of business.”
The US consumed about 1.6 million tonnes of refined copper last year, according to the US Geological Survey.
While the US has significant mines, producing about 850,000 tonnes of primary copper last year, it still relies on imports from key trade allies to fill the need.
Chile is the largest import source, accounting for 38 percent of total import volumes, followed by Canada and Mexico at 28 percent and 8 percent respectively.
RUN IT BACK: A succesful first project working with hyperscalers to design chips encouraged MediaTek to start a second project, aiming to hit stride in 2028 MediaTek Inc (聯發科), the world’s biggest smartphone chip supplier, yesterday said it is engaging a second hyperscaler to help design artificial intelligence (AI) accelerators used in data centers following a similar project expected to generate revenue streams soon. The first AI accelerator project is to bring in US$1 billion revenue next year and several billion US dollars more in 2027, MediaTek chief executive officer Rick Tsai (蔡力行) told a virtual investor conference yesterday. The second AI accelerator project is expected to contribute to revenue beginning in 2028, Tsai said. MediaTek yesterday raised its revenue forecast for the global AI accelerator used
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has secured three construction permits for its plan to build a state-of-the-art A14 wafer fab in Taichung, and is likely to start construction soon, the Central Taiwan Science Park Bureau said yesterday. Speaking with CNA, Wang Chun-chieh (王俊傑), deputy director general of the science park bureau, said the world’s largest contract chipmaker has received three construction permits — one to build a fab to roll out sophisticated chips, another to build a central utility plant to provide water and electricity for the facility and the other to build three office buildings. With the three permits, TSMC
TEMPORARY TRUCE: China has made concessions to ease rare earth trade controls, among others, while Washington holds fire on a 100% tariff on all Chinese goods China is effectively suspending implementation of additional export controls on rare earth metals and terminating investigations targeting US companies in the semiconductor supply chain, the White House announced. The White House on Saturday issued a fact sheet outlining some details of the trade pact agreed to earlier in the week by US President Donald Trump and Chinese President Xi Jinping (習近平) that aimed to ease tensions between the world’s two largest economies. Under the deal, China is to issue general licenses valid for exports of rare earths, gallium, germanium, antimony and graphite “for the benefit of US end users and their suppliers
Dutch chipmaker Nexperia BV’s China unit yesterday said that it had established sufficient inventories of finished goods and works-in-progress, and that its supply chain remained secure and stable after its parent halted wafer supplies. The Dutch company suspended supplies of wafers to its Chinese assembly plant a week ago, calling it “a direct consequence of the local management’s recent failure to comply with the agreed contractual payment terms,” Reuters reported on Friday last week. Its China unit called Nexperia’s suspension “unilateral” and “extremely irresponsible,” adding that the Dutch parent’s claim about contractual payment was “misleading and highly deceptive,” according to a statement
