Spraying kerosene over the DRAM inferno, US commerce secretary suggests reminiscence chip makers might face 100% tariffs except they decide to elevated US manufacturing

Final Friday, US reminiscence firm Micron broke floor on a brand new $100 billion multi-foundry advanced in Syracuse, New York, as a part of the corporate’s $200 billion venture to develop amenities in America. Joined by numerous visitors and politicians, the ceremony was additionally notable for acquainted remarks made by the US commerce secretary to reporters: international chip makers might be hit with 100% tariffs, except they make investments extra within the US.

As reported by Bloomberg, Howard Lutnick (above, second proper) identified that the potential of import levies, already addressed in a commerce accord with Taiwan, additionally applies to South Korean companies.

“Everybody who needs to construct reminiscence has two selections: They will pay a 100% tariff, or they will construct in America. That’s industrial coverage.”

Of extra relevance, although, is the truth that it is solely these corporations that manufacture HBM or excessive bandwidth reminiscence. These chips are used virtually completely for AI superchips: Nvidia’s Hopper, Blackwell, and Rubin monsters, together with AMD’s large Intuition accelerators, all depend on the stacked-DRAM modules to have as a lot reminiscence capability and bandwidth as potential.

A lot in order that in an try to fulfill the calls for of the AI market, reminiscence distributors have been favouring HBM manufacturing over normal modules, which is why we’re within the present DRAM disaster within the first place. It has been estimated that as a lot as $2 trillion can be globally invested into all issues AI-related by the top of 2026, so it is not exhausting to see how this has all come about.

The earlier US administration relied on its CHIPS Act to woo South Korean companies into investing extra of their US operations, with each Samsung and SK hynix receiving billions within the type of grants and loans, although neither agency manufactures the chips which are finally utilized in DRAM sticks or HBM modules in America, simply packaging (placing all of the dies right into a useable kind).

As as to whether the specter of import levies garners any additional funding from non-US reminiscence makers, along with that already agreed to in final yr’s commerce talks, it is too early to inform. But when the US authorities believes that it really works, then we definitely have not heard the final of 100% or extra tariffs.
