The US decision to impose a 25% tariff on selected high-end semiconductor imports looks less like a single trade action and more like the opening move in a broader campaign.
A White House official said the measure, announced on Wednesday by the US Commerce Department, was a “phase one” step to protect a strategically vital sector. Further announcements could follow. Much depends on talks with foreign governments and chipmakers.
The tariff applies to advanced computing chips, including Nvidia Corp's (NASDAQ:NVDA, XETRA:NVD) H200 and AMD’s MI325X. These are specialised processors used in artificial intelligence and data centres. They sit at the high-value end of the global chip market.
President Donald Trump has already floated a much tougher idea. He has threatened tariffs of up to 100% on chips not made in the US. The aim is to force more manufacturing onshore.
The White House has tried to limit immediate disruption. Chips imported for the US technology supply chain, or to support domestic manufacturing, are exempt for now.
Still, the message is clear. Washington is prepared to use trade policy aggressively to reshape the semiconductor industry. For companies such as Nvidia and Advanced Micro Devices, the risk is growing policy uncertainty.
For US allies and rivals alike, this looks like the start of a longer negotiation, not the end of one.
