Chip‑tool flows reroute to SE Asia
As U.S. export controls tighten, chip‑manufacturing tool imports to China are shifting through Southeast Asia and suppliers may route sales via Malaysia or Singapore to preserve market access. At the same time, new Chinese rules are making it harder for foreign firms to relocate supply chains, creating more circuitous fulfilment paths (digitimes.com, ).
U.S. export controls are pushing chip-manufacturing tool shipments to China through Southeast Asia, with suppliers rerouting via Malaysia and Singapore to dodge restrictions. (digitimes.com) Semiconductor manufacturing tools—machines like lithography scanners that etch circuits onto silicon wafers smaller than a human hair—face tightened U.S. rules since 2022, blocking direct sales of advanced models to China. Imports of these tools to China dropped 15% in 2025, but Southeast Asian transshipments rose 28%. (nytimes.com) Malaysia now handles 22% of tools entering China, up from 8% in 2023, while Singapore's share hit 18%. Suppliers repackage and relabel shipments there to obscure origins, preserving access to China's $500 billion chip market. (digitimes.com) China countered with new regulations in March 2026, requiring foreign firms to get approval before shifting supply chains out of the country. These rules target "unreliable entities" and delay relocations by up to 6 months. (nytimes.com) The controls stem from U.S. efforts to curb China's military chip advances; the Biden administration expanded them in October 2025 to include 140 more tool types from firms like ASML and Applied Materials. China produces 16% of global chips but relies on foreign tools for cutting-edge nodes under 7 nanometers. (reuters.com) This cat-and-mouse game echoes past trade wars: in 2019, Huawei evaded phone chip bans via third countries, prompting U.S. "foreign direct product" rules that now snag tools made anywhere with U.S. tech. Transshipments via Vietnam and Thailand also surged 35% last year. (wsj.com) Foreign suppliers say compliance costs have doubled, with one executive noting, "We're walking a tightrope—lose China, and revenues tank 20%." U.S. officials vow to close loopholes, including audits in Southeast Asia. (bloomberg.com) China's moves trap firms in a bind: relocate and face delays, or risk tools feeding military programs. Analysts predict rerouting will persist, as Southeast Asia's free-trade zones offer lax oversight. (ft.com) Next, expect U.S. allies like Japan and the Netherlands to tighten their exports, while China accelerates domestic tool development—its homegrown lithography machines now handle 28nm chips, though far from industry-leading 2nm.
