TSMC was reported to be under U.S. export-control investigation over chips it made for Chinese chip designer Sophgo after one reportedly matched a chip found inside Huawei’s Ascend 910B AI processor. Reuters-based reports published April 8–9, 2025, said a potential penalty could reach $1 billion or more. They described a possible settlement—not a final fine—and did not establish that TSMC sold chips directly to Huawei or knowingly supplied it.
What prompted the investigation?
The reported issue centers on the path a chip may have taken: TSMC fabricated a chip ordered by Sophgo, and a chip matching it was reportedly found inside Huawei’s Ascend 910B AI processor. The U.S. Commerce Department was reported to be examining TSMC’s work for Sophgo.
That reported match raises questions about where the chip ended up and whether export-control rules applied. It does not, by itself, establish who transferred the chip to Huawei, what TSMC knew, or whether a violation occurred. The reporting relied on people familiar with the matter and did not report a final agency finding.
How is Huawei involved?
Huawei is involved because the chip matching evidence reportedly connected TSMC’s Sophgo work to Huawei’s Ascend 910B. Huawei is on the U.S. Entity List. U.S. Bureau of Industry and Security materials describe a Foreign Direct Product Rule that can restrict certain foreign-produced items made using U.S. technology from reaching Huawei without authorization.

The rule matters because a product does not necessarily have to be made in the United States for U.S. export controls to apply. Whether a particular foreign-produced chip falls within the rule depends on the applicable requirements and facts. The public reporting summarized here does not establish a final determination that this chip was covered, that an authorization was absent, or that TSMC violated the rule.
Did TSMC send chips directly to Huawei?
The reported chain is TSMC fabrication, a Sophgo order, and a matching chip reportedly found in Huawei’s processor. That is different from evidence that Huawei ordered the chip directly from TSMC. The reports do not establish a direct sale, or show that TSMC knowingly shipped chips to Huawei.

Why is the potential penalty reported at $1 billion?
Reuters-based coverage said the possible penalty could be $1 billion or more under export-control rules that can allow fines of up to twice the value of violating transactions. The reported figure is a potential exposure, not a calculation of a final amount and not an automatic penalty. The coverage does not provide a public transaction valuation or final agency calculation that would let readers independently derive the $1 billion figure.
The distinction is important: a statutory maximum or settlement possibility describes what could happen under a set of facts; it does not show that the government has determined a violation occurred or selected a specific fine.

What is known about the number of chips?
Reuters-based coverage in 2025 cited Lennart Heim of RAND estimating that nearly 3 million chips were involved in recent years. This is an expert estimate reported by the coverage, not a disclosed U.S. government count or an audited shipment total. It should not be read as proof that TSMC shipped that number directly to Huawei.
Has the United States already fined TSMC?
The April 8–9, 2025 reports described a possible settlement and a potential penalty while the matter was under investigation; they did not announce a final fine. Taiwan Economy Minister Kuo Jyh-huei said his ministry had not received notification of a possible fine and was quoted as saying, “TSMC is a company that respects laws and regulations.” A TSMC spokesperson was reported to be in a quiet period and did not provide further comment.

Those statements describe what was reported at that time. They are not an update on any later agency action. The reporting covered here does not include a completed settlement, charging document, closing date, or final enforcement notice.

The central issue is not simply whether a chip made by TSMC appeared in a Huawei processor. Investigators would need to assess the transaction and applicable export-control requirements. Based on the reported facts, the unresolved questions include:

- Technical identification: what supports the reported match between the TSMC-made chip and the chip in the Ascend 910B.
- Rule coverage: whether the chip and the manufacturing process met the conditions for U.S. export controls, including the Foreign Direct Product Rule.
- Valuation and penalty: what transactions, if any, were found to violate the rules and how their value would affect a penalty ceiling.
- Enforcement decision: whether the investigation leads to a settlement, other action, or no penalty.
Until an authoritative enforcement outcome is announced, the $1 billion figure should be described as a reported possibility, not a fine TSMC has been ordered to pay.
