Taiwan Vice Premier Cheng Li-chiun confirmed on May 28, 2026, that the United States has set no timetable for implementing Section 232 tariffs on semiconductors, while reiterating that preferential treatment under any future measures has already been secured under the January trade deal. The Federal Register published the tariff structure on Thursday, making it effective retroactively from May 1. Under the bilateral agreement finalized in February, Taiwanese goods face a base tariff rate of 15% – down from the 32% IEEPA-based tariffs imposed in 2025 before the Supreme Court struck them down in February 2026. Specific goods including auto parts, aircraft components, wood, and steel face removal or reduction to that 15% ceiling. Semiconductors and semiconductor manufacturing equipment remain under a separate, open investigation – and it is that open investigation, as YourDailyAnalysis maps it, that defines the real uncertainty the Cheng statement cannot resolve.
The Section 232 investigation into chips is the structural problem that no vice premier’s statement can eliminate. Section 232 of the Trade Expansion Act of 1962 authorizes the president to impose tariffs on national security grounds with enormous discretionary flexibility. The Trump administration has used it in semiconductors, steel, aluminum, and pharmaceuticals. The Taiwan trade agreement explicitly secured preferential treatment “taking into account Taiwan’s economic and national security alignment and high-tech strategic partnership with the United States” – language that appears protective but carries no numerical commitment. What “preferential treatment” means when a Section 232 tariff is eventually announced depends entirely on the specific rate structure, the exemption thresholds, and whether TSMC’s U.S. production volumes qualify for different treatment than its Taiwan-based exports.
The January deal’s architecture is worth understanding precisely. Taiwan committed to $250 billion in U.S. investment via an AIT-TECRO MOU signed January 15, 2026, covering semiconductor supply chain manufacturing, AI applications, and energy. Taiwan also committed to purchasing $44.4 billion in U.S. LNG and crude oil, $15.2 billion in aircraft and engines, and $25.2 billion in power generation equipment through 2029. The U.S. trade deficit with Taiwan hit $150.1 billion in 2025 – more than double the 2024 figure – driven by AI chip imports. That deficit is the political pressure Section 232 tariffs would ostensibly address. YourDailyAnalysis traces the core tension back to a structural mismatch: the trade architecture rewards Taiwan’s alignment, but the bilateral surplus keeps generating pressure that the deal’s language cannot fully neutralize.
Position the Cheng statement against the Supreme Court ruling. After the court struck down IEEPA-based tariffs in February, Trump imposed a 10% global tariff under Section 122 of the Trade Act and initiated Section 301 investigations into structural excess capacity manufacturing in Taiwan and 15 other markets. Section 301 investigations lead to additional tariffs and can overlap with Section 232 actions. Taiwan could simultaneously face Section 232 chip tariffs, Section 301 excess capacity tariffs, and the base 15% rate on general goods – a layered structure that the January deal’s language would need to address across multiple tracks. The editors at Your Daily Analysis note that the legislative situation has become substantially more complex than the bilateral trade deal headline suggests, and that Cheng’s confidence in existing protections may be tested by mechanisms not fully covered in the original agreement.
There is a counter-argument that treats Taiwan’s position as stronger than the uncertainty implies. Taiwan’s $250 billion investment commitment gives Washington a direct financial stake in Taiwanese competitiveness. A Section 232 tariff that materially damages TSMC’s ability to invest in Arizona fabs and U.S. supply chains would be self-defeating. U.S. Trade Representative Jamieson Greer has said the agreement will significantly enhance supply chain resilience in high-technology sectors. Political incentives and strategic logic both argue against a punishing chip tariff. But political incentives have not consistently prevailed in this administration’s trade decisions. The investment commitment is the strongest protection Taiwan has – not the legal language, but the economic stake Washington has taken in Taiwanese industrial capacity performing well.
Watch the Section 232 semiconductor investigation timeline and any signals from USTR about scope and rate structure. That single variable will determine whether Taiwan’s January deal holds its value or requires renegotiation.
