Trump has already hiked tariffs on Chinese imports, steel, aluminum, and certain Canadian and Mexican goods. Higher car levies are expected this week.
Analysts have floated several prospective tariff rates, but the White House has not stated how high they could go.
On the campaign trail last year, Trump advocated for a 10% duty on all imports, sometimes suggesting that it could be 20% or even 60% on imports from China.
Once elected, he introduced the idea of "reciprocal" tariffs.
