A COVID-19 lockdown in Shenzhen, China’s most famous electronics manufacturing hub, could throw the already struggling global supply chain into further chaos, experts told Motherboard.

Manufacturers are already reporting shipment delays of tech products and parts—flash drives, glass iPhone screens, and more—after factories were forced to shut down to comply with the lockdown order the country announced Sunday. At the time, China was reporting 3,400 cases nationwide, the highest in two years, driven by the ‘stealth omicron’ variant, a new lineage of the omicron variant.
