U.S. Entity List: Huawei / HiSilicon (May 2019)

The U.S. Department of Commerce added Huawei Technologies and its affiliates — including chip design arm HiSilicon — to the Entity List on May 16, 2019, citing national security concerns. The listing requires U.S. suppliers to obtain a license before selling or transferring items subject to the Export Administration Regulations (EAR) to Huawei. A subsequent Foreign Direct Product Rule (FDPR) in 2020 extended the restriction to any chip designed with U.S. software or equipment and manufactured anywhere in the world for Huawei, effectively cutting off TSMC and other foundries from accepting Huawei orders for advanced chips.
