Resolution criterion
Yes if a presidential proclamation or a Federal Register notice changes the 25% ad valorem rate (up or down), OR changes the scope of the exemption applying to imports destined for US data centers, whether by broadening it or narrowing it.
Verified starting state
A 25% duty has been in force since 15 January 2026, with broad exemptions (US data centers, R&D, startups) and a review clause dated 1 July 2026 for semiconductors destined for data centers. The data center exemption is strongly defended by the hyperscalers.
What pushes it up
- A formal review clause specifically targeting semiconductors for data centers was scheduled for 1 July 2026, creating a high likelihood of a subsequent regulatory adjustment [1].
- Strong lobbying efforts by hyperscalers to defend or expand exemptions exert significant pressure for a modification of the current scope [1].
- The U.S. government has demonstrated recent activity in modifying other Section 232 tariffs, such as those on steel and aluminum, indicating the mechanism is actively used for trade policy adjustments [4].
What pushes it down
- No presidential proclamation or Federal Register notice regarding semiconductor tariffs has been reported in the three months following the scheduled review date, which may suggest a decision to maintain the status quo [4].
- The complexity of semiconductor supply chains and inter-agency coordination can lead to significant delays in translating a review into a formal modification.
