A bipartisan group of US lawmakers has called on the Commerce Department to investigate and potentially ban the sale of TP-Link Technologies’ networking products by the end of November, citing significant national security risks. In a formal letter to Commerce Secretary Howard Lutnick, the legislators expressed concerns that TP-Link’s routers and internet-connected cameras, produced by a company with alleged ties to the Chinese Communist Party (CCP), could be exploited for espionage against US military personnel, critical infrastructure, and households. They emphasized the rapid expansion of TP-Link’s market share in internet-connected security cameras and the potential for CCP-linked entities to misuse these devices for surveillance, blackmail, or extortion. The lawmakers urged the Commerce Department to assess the risks and determine whether existing information and communications-technology security measures are adequate. They also requested recommendations on adding TP-Link to the Federal Communications Commission’s Covered List, conducting a broader study on CCP-linked camera manufacturers, and issuing public advisories through the FBI and Department of Homeland Security. This potential ban could mark the largest removal of Chinese telecommunications equipment from the US market since the 2019 crackdown on Huawei. TP-Link has denied the allegations, asserting its commitment to providing secure products and resolving concerns through measures like onshoring development functions and enhancing cybersecurity. The company also highlighted its restructuring efforts, including the establishment of TP-Link Systems in California, which operates independently from its China-based counterpart. The controversy follows a multi-agency investigation into TP-Link’s routers, which dominate 65% of the US home and small-business market, amid evidence of their involvement in cyber campaigns traced to China-backed threat actors.
