The U.S. will levy 100% tariffs against China beginning next month, President Donald Trump said Friday, announcing the duties after Beijing clamped down on export controls for rare earth materials this week.

Trump announced the tariffs in a Truth Social post, saying they would start “November 1st, 2025 (or sooner, depending on any further actions or changes taken by China).”

The tariffs will stack “over and above” other tariffs China is already paying, according to Trump, who added export controls will be placed on “any and all critical software” on Nov. 1.
