US Halts Chip Shipments to Hua Hong
Analysis based on 11 articles · First reported Apr 28, 2026 · Last updated Apr 29, 2026
The U.S. export restrictions on Hua Hong Semiconductor are expected to negatively impact U.S. chip equipment companies like Lam Research, Applied Materials, and KLA Corporation, potentially leading to billions in lost sales. This action also increases geopolitical tensions between the United States and China, affecting the broader technology sector and global supply chains.
The United States — United States Department of Commerce has ordered major U.S. chip equipment companies, including Lam Research, Applied Materials, and KLA Corporation, to halt certain tool shipments to Hua Hong Semiconductor, China's second-largest chipmaker. This move is aimed at slowing China's development of advanced chips, particularly those used for artificial intelligence. The restrictions target two Hua Hong Semiconductor facilities, including Novatek Microelectronics' Shanghai plant, which is reportedly developing 7-nanometer chipmaking processes. This action follows reports that Hua Hong Semiconductor had developed advanced chip manufacturing technologies. Shares of the affected U.S. companies declined following the announcement. The restrictions are part of a broader U.S. effort to safeguard its technological lead on national security grounds, but they are expected to increase tensions with China ahead of a scheduled meeting between Donald Trump and Xi Jinping.
