Summary
On November 11, 2024, TSMC suspended sub-7nm chip services to Chinese AI and GPU chipmakers following a US Commerce Department directive, as part of Washington's broader strategy to limit China's access to advanced semiconductor technology. The move creates supply chain disruptions and may shift orders to Samsung and SMIC, though both face their own export control constraints. This represents an escalation of US semiconductor export controls targeting AI-relevant compute infrastructure.
Key Points
- •US Commerce Department issued a directive requiring TSMC to halt sub-7nm chip exports to China starting November 11, 2024, targeting AI and GPU applications.
- •TSMC notified affected Chinese clients of the cessation, impacting companies focused on autonomous driving, cloud computing, and AI chip development.
- •Chinese firms are expected to shift orders to SMIC and Samsung, though Samsung also faces US export control restrictions due to its use of US-origin technology.
- •The directive builds on prior restrictions imposed on Nvidia and AMD, escalating Washington's effort to limit dual-use semiconductor technology access for China.
- •SMIC's technology and capacity limitations raise questions about whether Chinese domestic foundries can adequately substitute for TSMC's advanced process nodes.

On November 11, 2024, TSMC reportedly suspended its sub-7nm process services to China's AI and GPU chipmakers following the Huawei "chip controversy," triggering widespread industry impacts and potential order transfers. The company has already issued notifications to affected clients regarding the cessation.
## US halts AI chip exports to China
[The US Commerce Department issued an "is informed" directive to TSMC](https://www.digitimes.com/news/a20241108PD220/tsmc-ai-gpu-technology-7nm-ai-chip.html), as reported by _Reuters_ on November 10, halting advanced sub-7nm chip exports to China starting November 11. This measure aligns with the US strategy to limit China's access to high-end semiconductor technology for national security reasons.
The restriction, which targets AI applications, may impact TSMC's operations in China, where demand for high-performance AI chips continues to grow. TSMC( [2330.TW](https://www.digitimes.com/finance/company.asp?cid=32)) has affirmed its commitment to regulatory compliance but has not yet publicly commented on the order.
This latest directive marks another step in Washington's effort to restrict technologies with dual-use potential, building on similar measures previously imposed on other leading chipmakers like Nvidia and AMD.
## Industry ripples
Industry analysts are closely monitoring the effects of TSMC's decision on global supply chains and its China strategy. Chinese firms are likely to shift orders to SMIC and Samsung,
