Taiwan Semiconductor Manufacturing Co. experienced roughly a 1% decline in premarket trading on Tuesday following reports that authorities in Taipei are exploring much tougher restrictions on sales of AI chips to China. The deliberations, as described by people familiar with the matter, would mark a substantial expansion of Taiwan's legal powers to control shipments of advanced semiconductor hardware.
What officials are considering
According to the report, Taiwanese policymakers are weighing rules that would bar sales of AI chips to all Chinese customers, rather than limiting prohibitions to specific entities already on blacklists such as Huawei Technologies. The contemplated framework would, for the first time, provide Taiwan with statutory authority to prosecute unauthorized exports of AI chips to China as a criminal offense. That change would represent a departure from Taiwan's current legal posture.
At present, exports of certain advanced chips to China are prohibited under U.S. export controls, but Taiwan does not treat such transfers as criminal violations under its own laws. That gap has constrained the scope of domestic enforcement. Taiwan's first publicly known detentions tied to the recent export concerns occurred only last month and were brought on the narrower basis of alleged document falsification rather than for the export itself.
The plan under discussion would impose a processing-power threshold above which AI chip sales to Chinese buyers could be restricted. That approach would reflect the policy path Washington has followed since 2022. Details of thresholds, enforcement mechanisms and legal language are still being finalized, and senior officials on both sides have not yet reviewed or signed off on any potential agreement.
Context of broader negotiations and enforcement concerns
These measures are being discussed as part of broader trade negotiations with the United States. The deliberations take place against mounting concern in Washington over the diversion of advanced hardware, including AI servers outfitted with Nvidia chips, from Taiwan to China. U.S. policymakers have been moving to close potential loopholes that could allow advanced chips to reach subsidiaries of Chinese companies located outside China.
Most recently, U.S. regulators have acted to prevent possible circumvention of export controls. In parallel, U.S. lawmakers have pressed U.S. agencies to address the practice of Chinese firms using overseas subsidiaries to obtain custom-designed chips from contract manufacturers. Specifically, two senators have written to the head of the Bureau of Industry and Security urging regulators to confront orders placed by overseas affiliates of Chinese firms with contract chipmakers such as Taiwan Semiconductor Manufacturing Co.
Where things stand
At this stage, the proposals remain under internal discussion. Officials have yet to finalize the thresholds, enforcement provisions or legal changes required to make unauthorized exports a criminal matter under Taiwanese law. Senior officials on either side of the discussions have not completed a formal review or endorsement of any agreement. Market participants reacted to the reporting with a modest downward move in the shares of Taiwan Semiconductor Manufacturing.
Key points
- Taiwan is reported to be considering export controls that would bar AI chip sales to all Chinese buyers and create criminal penalties for unauthorized exports.
- The contemplated measures would align Taiwans enforcement tools more closely with U.S. policy, including restricting chips above a processing-power threshold.
- Semiconductor markets and firms involved in contract manufacturing and AI hardware supply chains are directly affected by the possible changes.
Risks and uncertainties
- Legal and enforcement uncertainty - Details have not been finalized and no senior official sign-offs have occurred, leaving the scope and timing of any changes unclear.
- Trade negotiation outcomes - The measures are being discussed as part of broader talks with the United States, so the final form of any restrictions could depend on those negotiations.
- Potential for regulatory gaps or loopholes - Past instances, such as alleged diversions via subsidiaries outside China, have prompted additional U.S. scrutiny and could complicate effective enforcement.
