While U.S. President Donald Trump’s latest salvo in the global trade war stopped short of targeting the critical semiconductor sector, the reprieve may be short-lived for many Chinese chipmakers.

Under a sweeping “reciprocal tariff” plan announced Wednesday, China will be hit with an additional 34% tariff, bringing the total levy on Chinese goods entering the U.S. to 54% starting April 9. Semiconductors, along with copper, pharmaceutical and lumber products were exempted from the new rates — at least for now.
