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
- The tariff regime contains an explicit review clause for data center semiconductor exemptions, creating a formal regulatory process likely to result in adjustments [tier 1].
- Section 232 tariffs historically see frequent iterative modifications, tariff-rate quotas, and exclusion adjustments as domestic and international trade dynamics evolve [tier 1].
What pushes it down
- Hyperscalers possess substantial lobbying resources and strongly defend the current data center exemption, creating significant resistance to narrowing the scope [tier 1].
- The 1 July 2026 review date has passed without an immediate reported modification, suggesting the administration may maintain the status quo [tier 1].
- Recent press coverage comprises only commentary and think tank analysis [tier 4: articles 0, 2, 4], which cannot independently corroborate any pending executive action.
What would move this number most
Whether the administration decides to narrow the data center exemption to capture more tariff revenue or broaden exemptions to appease hyperscalers and tech industry pressures before mid-2027.

- 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].
- What pushes it up. Strong lobbying efforts by hyperscalers to defend or expand exemptions exert significant pressure for a modification of the current scope [1].
- What pushes it up. 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].
- What pushes it down. The complexity of semiconductor supply chains and inter-agency coordination can lead to significant delays in translating a review into a formal modification.
- What would move this number most. The outcome of the July 2026 review process, which has not yet been publicly disclosed in the provided sources.
