US Section 232 Semiconductor Tariffs Face April 14 Review — Broader Chip Expansion Possible

The Trump administration's 25% ad valorem Section 232 tariff on advanced computing chips — enacted January 15, 2026 and targeting products including the NVIDIA H200 and AMD MI325X — enters a mandatory first review window on April 14, 2026. The Commerce Department and the USTR are required to deliver a trade-negotiation update by that date, with a potential expansion of tariffs to a broader class of semiconductors possible within 90 days of the report. The April 14 deadline is the most immediate near-term policy event affecting the global chip industry.

TSMC has committed $165 billion to US manufacturing expansion in exchange for preferential treatment: Taiwanese chipmakers investing in US fabs may import up to 2.5x their planned US capacity duty-free during the approved construction period. The US is also reportedly mulling tariff exemptions for Amazon, Google, and Microsoft on TSMC-made chips, contingent on their investment commitments to domestic AI infrastructure. A separate, more targeted review of tariffs on US data center semiconductors is scheduled for July 1, 2026.

The tariffs include exemptions for imports supporting US data centers, research, consumer electronics, and domestic manufacturing expansion — but Samsung and SK Hynix remain exposed, as their HBM chips embedded in AI accelerators are not yet covered by carve-outs. TrendForce analysts have noted that suppliers are being pushed to absorb pain-sharing demands from major customers, creating margin pressure across the memory supply chain. The outcome of the April 14 review will set the tone for chip trade policy through at least mid-2026.
