Chipmakers including Qualcomm Inc., Xilinx Inc. and Broadcom Inc. have told employees they won’t supply to the Chinese electronics giant until further notice, Bloomberg News reported late Sunday in the U.S. Those companies will need clarification from the Trump administration on whether they can ship to Huawei, so for now it seems they’re erring on the side of caution.
