Taipei's export-control bureaucrats spent the week working through new restrictions on advanced AI semiconductors bound for China, the Taipei Times reported — a move that would formally pull Taiwan's chip trade rules into alignment with Washington's tech blockade on Beijing.

The proposed curbs, still under review inside Taiwan's executive branch, would extend the island's oversight into the AI accelerator category — the same silicon at the center of two years of US Commerce Department controls. Officials in Taipei framed the move, the Times reported, as alignment with allied policy rather than a fresh embargo of its own.

What does Taiwan export in AI?

The island does not brand the finished AI accelerators that ship into Chinese hyperscale data centers — those come from US companies — but Taipei retains jurisdiction over foundry services, design IP that originates on the island, and the advanced packaging flows that decide whether a system builder can field a competitive training cluster.

Taiwan Semiconductor Manufacturing Company (TSMC) manufactures the silicon for Nvidia's H100, H200, and Blackwell B100/B200 GPUs and AMD's MI300 and MI325 accelerators, running on 5nm and 3nm process nodes with chip-on-wafer-on-substrate (CoWoS) packaging out of Hsinchu and Tainan fabs.

Why align with Washington now?

The United States, Japan, and the Netherlands have spent two years building a coordinated chip export regime aimed at Beijing.

The Commerce Department issued its first AI accelerator controls in October 2022 and tightened them in October 2023. Tokyo and The Hague pulled ASML and Nikon into joint lithography restrictions under the January 2023 trilateral agreement. Taiwan's absence from that perimeter was conspicuous — a gap Taipei now intends to close.

What the curbs might cover

The Taipei Times did not detail a specific product list. The most likely targets, based on what would mirror Washington's existing scope: advanced logic below 7nm, CoWoS and CoWoS-L interposers, and high-bandwidth memory (HBM) integration.

A Taiwan-side restriction would matter because TSMC's 7nm, 5nm, and 3nm capacity — roughly 60% of the company's 2024 revenue mix — runs almost entirely out of Taiwanese fabs.

What changes commercially

For Chinese hyperscalers — Alibaba, Baidu, Tencent, ByteDance — the practical effect will be limited in the near term. Most high-end AI silicon already requires Commerce Department licenses to clear Chinese customs.

The Taiwan-side curb changes the political map more than the product map. It gives Taipei its own lever in any future deal, removes the ambiguity around Taiwanese-origin silicon, and confirms that the island's semiconductor industry will operate inside the US-led export regime rather than alongside it.

What it changes geopolitically

Taiwan's relationship with Beijing remains the underlying variable. The island's January 2024 ballot returned Lai Ching-te and the Democratic Progressive Party to power. The new government has signaled continuity on China policy.

Beijing has not commented publicly on the Taipei Times report. Expect commentary within the week.

What comes next

The Taipei Times describes the curbs as still under consideration. The next milestone: a published draft list of restricted categories and product definitions.

Until that list arrives, expect TSMC, MediaTek, and the island's smaller AI design houses to begin quiet compliance reviews — and watch the procurement desks at Chinese hyperscalers, because that is where the new rules will hit first.
