After Hurricane Heleni caused two high-purity quartz mines in North Carolina to shut down, global semiconductor manufacturers are closely monitoring their quartz supply - the material is crucial to the chip industry.

The world's largest chip manufacturers, Taiwan Semiconductor and German company Infineon Technologies, have issued statements stating that they are closely monitoring the situation but believe it will not have a significant impact on their operations.

South Korea's Samsung Electronics and SK Hynix stated that they do not expect any major impact. TSMC supplier Vanguard International is assessing inventory and maintaining close contact with all suppliers. Given that semiconductor companies typically have reserves for key components, and operations in North Carolina will eventually resume, the current situation still presents uncertainties for the global chip manufacturing industry. One of the world's largest silicon suppliers, GlobalWafers, also stated on Thursday that there is no need to worry at the moment, as the supply chain has sufficient inventory to cope with temporary supply interruptions, and the ability to fulfill existing orders is not expected to be affected.

North Carolina's quartz mining companies Sibelco and Quartz were affected by Hurricane Heleni, both suspending production on September 26, and it is currently unclear when production will resume. Hurricane Heleni caused flooding, power outages, communication disruptions, and casualties in the region.
