Chip controls strain enforcement

U.S. chip controls are now bogged down less by writing new rules than by policing workarounds and clearing a growing license backlog. (justice.gov 1) (justice.gov 2) In March 2026, federal prosecutors unsealed two separate cases alleging schemes to send controlled artificial intelligence chips and servers to China through third countries. One case said the route ran through Thailand; the other alleged “massive quantities” of servers with controlled United States artificial intelligence technology were diverted to Chinese customers. (justice.gov 1) (justice.gov 2) At the same time, companies trying to ship approved products are still waiting on Washington. The Bureau of Industry and Security shifted Nvidia H200 and Advanced Micro Devices MI325X exports to China to case-by-case review in January 2026, after Nvidia’s H20 and Advanced Micro Devices’ MI308 had already been pushed into licensing in April 2025. (bis.gov) (nvidianews.nvidia.com) (ir.amd.com) China’s import data points to the same pressure from another angle: the trade is moving, but the route is changing. TrendForce, citing a Nikkei Asia analysis of 2025 customs data, reported that China’s direct imports of semiconductor manufacturing equipment from the United States fell more than 34% to about $2 billion, the lowest since 2017. (trendforce.com) The same report said shipments from Singapore reached $5.7 billion in 2025, up more than 17% from a year earlier, while imports from Malaysia rose to $3.4 billion, more than double 2024 levels. The Netherlands and Japan still ranked as China’s main external sources of chipmaking tools by shipment origin. (trendforce.com) That matters because chip controls hit two different parts of the supply chain. One set targets the processors that train and run artificial intelligence models; another targets the lithography, etching, deposition, and inspection tools that factories need to make chips in the first place. (bis.doc.gov) (semi.org) Washington has tightened both tracks over the past three years, but the enforcement load has grown with them. The March indictments described alleged use of front companies, false statements and transshipment hubs, while exporters still have to file through the Commerce Department’s SNAP-R licensing system for controlled shipments. (justice.gov 1) (justice.gov 2) (dev-snapr.apps.bis.doc.gov) The commercial stakes are visible in company filings. Nvidia said in May 2025 that the new H20 license requirement forced a $4.5 billion charge, and Advanced Micro Devices said the April 2025 controls applied to its MI308 products and later disclosed an $800 million inventory-related hit tied to those restrictions. (nvidianews.nvidia.com) (amd.com) (ir.amd.com) China is also trying to reduce its dependence on foreign gear altogether. TrendForce reported in February that Beijing wants more than 50% local sourcing for equipment in expanding domestic fabs and a 70% localization rate for mature-process equipment by 2027. (trendforce.com) So the contest has shifted from a rulebook problem to a capacity problem: investigators have to catch rerouting, licensing officers have to process more edge-case applications, and manufacturers keep redesigning products and supply chains around each revision. The rules are still tightening, but the bottleneck now sits in the people and pathways needed to enforce them. (justice.gov) (justice.gov) (bis.gov)
