Sources familiar with the matter stated that a Tennessee factory producing polysilicon for the U.S. semiconductor supply chain is at risk of closure after the Trump administration's new trade measures drove away its two remaining customers. ^[1] Germany's Wacker Chemie, which produces polysilicon used in semiconductors and solar panels, is considering closing its Charleston, Tennessee facility, according to unnamed sources. ^[2] Germany's Wacker, which produces polysilicon for chips and solar panels, will make a decision in the coming weeks on whether to close its Charleston, Tennessee, facility that employs about 600 workers. ^[3] The move follows a White House proclamation last month that seeks to incentivize purchases of American polysilicon, according to sources who declined to be named because the matter was not public. ^[4] Wacker stated that the proclamation does not effectively support the use of U.S.-made polysilicon as it currently reads and that the company is in active discussions with the administration to achieve the policy's goal. ^[5] The article suggests that President Trump's bid to shield the U.S. chip supply chain could backfire if Wacker Chemie closes its Tennessee facility. ^[6]
