The U.S. Commerce Department’s Bureau of Industry and Security has begun enforcing the latest round of semiconductor export control updates, which extend restrictions to additional categories of AI-capable chips, advanced packaging equipment, and semiconductor manufacturing software. The controls, first imposed in October 2022 and progressively tightened through 2024 and 2025, now cover a broader range of products and end-uses than at any point since the Cold War-era COCOM regime. For Asian semiconductor companies, the regulatory landscape has evolved from a defined set of prohibitions affecting a narrow category of leading-edge products into a comprehensive framework that touches equipment, materials, talent, and intellectual property across the value chain.
The scope expansion is most significant for advanced packaging technology, which has emerged as the binding constraint on AI chip production. SK Hynix’s $13 billion investment in a new packaging facility in Cheongju and Samsung’s integrated packaging capabilities both involve technologies, including thermal compression bonding and hybrid bonding, that are now subject to enhanced end-use monitoring. The controls do not prohibit these investments outright, but they require that companies demonstrate their packaging equipment and processes are not being used to produce chips destined for restricted end-users. The compliance burden for vertically integrated producers that package chips for both restricted and unrestricted customers has increased materially.
TSMC’s position illustrates the compliance complexity. The company operates as a contract manufacturer serving customers across the full spectrum of end-uses, from U.S. defense contractors to Chinese AI startups. Its $52-56 billion 2026 capex includes Arizona facilities that will produce chips under U.S. jurisdiction and Taiwan facilities that produce for global customers under Taiwanese export control rules. The regulatory requirement to ensure that no restricted technology reaches prohibited end-users requires real-time customer screening, manufacturing segregation, and documentation systems that add cost and complexity to operations that were historically managed as a single production flow.
Japan and the Netherlands have aligned their export control regimes with the U.S. framework, restricting the sale of advanced lithography and semiconductor manufacturing equipment to China. Tokyo Electron, which derives significant revenue from Chinese customers, has implemented compliance systems that screen orders against the restricted end-user list and monitor shipments through the supply chain. The compliance costs for Japanese equipment manufacturers have been estimated at 2-3% of revenue, a meaningful margin impact for companies operating in a capital-intensive, cyclically sensitive industry. Dutch equipment manufacturer ASML has similarly adjusted its operations, restricting service and maintenance support for existing systems installed at Chinese facilities that fall within the control scope.
The enforcement posture has shifted from guidance to penalties. BIS has imposed civil penalties on several companies for violations of the semiconductor controls, and the Commerce Department has expanded its enforcement staff to support the increased caseload. The “know your customer” obligation has been interpreted broadly, with companies expected to conduct due diligence not only on direct purchasers but on end-users and intermediaries in the supply chain. For Asian semiconductor companies, this means that compliance is no longer a back-office function managed by trade counsel but a front-line business requirement that affects customer relationships, production planning, and capital allocation decisions.
For investors, the export control regime is a structural variable that must be incorporated into the valuation of every semiconductor company operating in Asia. The controls create winners (companies with diversified customer bases and compliance infrastructure) and losers (companies dependent on restricted Chinese demand). They also create regulatory uncertainty: each annual update to the controls has expanded their scope in ways that were not fully anticipated by the industry. Companies that build compliance capabilities proactively and maintain flexibility in their customer and production strategies are better positioned to navigate the evolving regulatory environment than those that treat export controls as a static constraint.
