Lidar sensor tech is the latest flashpoint in the US-China trade war, as the US lidar industry mounts a lobbying offensive against Chinese companies like Hesai
Tanya Snyder / Politico : X: @tsnyderdc , @tsnyderdc , @dunne_insights , @tsnyderdc , and @tsnyderdc X: Tanya Snyder / @tsnyderdc : @ousterlidar @HesaiTech Ouster says lidar made by adversary nations can be dangerous if it's used to spy on Americans. (Hesai denies that lidar is capable of storing and transmitting data outside the vehicle.) Ouster also raises alarms about military applications or the introduction of malware. Tanya Snyder / @tsnyderdc : @ousterlidar ... But not everyone is swayed by the national security argument Ouster is making. The U.S. buys *lots* of tech from China. Whether lidar is more security sensitive than any other part of the automotive supply chain is the subject of some debate. Michael Dunne / @dunne_insights : Fascinating story. US customers are advising Chinese lidar sensor company Hesai to hire lobbyists to sustain market access in America. Where are the US sensor makers? The sensors in those self-driving cars have become an international dispute https://www.politico.com/... via Tanya Snyder / @tsnyderdc : The players: @ousterlidar on the U.S. side and @HesaiTech on the Chinese side. Ouster now owns Velodyne, which had accused Hesai of patent infringement and settled. Ouster has since leveled similar charges that have been sent to arbitration. Tanya Snyder / @tsnyderdc : @ousterlidar @HesaiTech Those concerns are gaining traction in Washington. In July the House asked @DeptofDefense to look into its use of Chinese lidar. In Aug. CRS issued a report on the potential dangers of Chinese control of the lidar market. https://crsreports.congress.gov/ ... That's when Hesai lobbied up.
Context & Ripple Effects
The dispute follows Hesai's earlier pushback against U.S. national-security and privacy concerns, even as its U.S. market access became a focal point for domestic lidar rivals. The lobbying campaign turns an existing commercial contest into a policy fight over whether vehicle sensors should be treated as security-sensitive infrastructure.
The argument is not settled: Ouster alleges risks involving surveillance, military use, and malware, while Hesai says its lidar cannot store or transmit data outside a vehicle. That divide matters because lawmakers are asking the Defense Department to review Chinese lidar use.
First-order effects
- U.S. lidar makers, led by Ouster, gain a concrete policy channel to press for scrutiny of Hesai and other Chinese suppliers; Hesai must spend more effort defending its access to the U.S. market.
- The House's request for a Defense Department review puts public-sector procurement and security assessments under immediate pressure, regardless of whether the allegations are ultimately substantiated.
Second-order effects
- Automakers and other lidar buyers may face additional supplier diligence and procurement uncertainty as the security claims become part of purchasing decisions, not just competitive marketing.
- Hesai's lobbying and public rebuttals are likely to become as consequential to its U.S. position as product competition, echoing its earlier response to U.S. security and privacy concerns.
Third-order effects
- If reviews and lobbying translate into formal restrictions, lidar could join a broader set of dual-use components where supply-chain origin shapes market access alongside price and performance.
- The later Defense Department designation dispute illustrates the legal and evidentiary constraints on this approach: durable restrictions will depend on agencies being able to support them under applicable criteria.
The trend: Lidar is becoming another dual-use technology market in which U.S.-China rivalry increasingly determines which suppliers can compete, not merely which sensors perform best.
