The US action, with effect from December 31, rescinded TSMC’s fast track export privilege known as Validated End User (VEU) status, which meant future shipments of US-origin semiconductor equipment to the Taiwanese firm’s Nanjing fabrication plant would require individual licences.
Without the blanket VEU coverage, sourcing chipmaking gear would be more difficult for TSMC, according to a Macquarie Group research note on Tuesday.
“If licence approvals are delayed, fabs may run into shortages that could disrupt operations within months,” the note said.
