The rules create a more explicit prohibition on the export of components like semiconductors, antennas and batteries for Huawei 5G devices, making the ban more uniform among licensees. Some companies had previously received licenses that allowed them to keep shipping components to Huawei that the Chinese company may have then used in 5G equipment, while other companies were already subject to tighter restrictions.
The Biden administration has informed some suppliers to China’s Huawei Technologies Co. of tighter conditions on previously approved export licenses, prohibiting items for use in or with 5G devices, according to people familiar with the move.
The 5G ban is effective as of this week, according to the people, who asked not to be identified to discuss nonpublic communications.
