WASHINGTON - US President Donald Trump on Thursday signed an executive order imposing minimum import prices and a 15 percent tariff on products made from polysilicon, a key material for solar panels and semiconductors.
The minimum import prices will be set at 21 US dollars per kilogram for polysilicon and 100 dollars per kilogram for polysilicon ingots and wafers, according to a White House proclamation. The new trade measures are scheduled to take effect on Dec 4.
Trump also directed the US Commerce Department to establish a program to encourage investment in domestic production of raw polysilicon and related downstream products.
According to a White House fact sheet, the measures are aimed at creating "a level playing field for American producers of these strategic goods," encouraging the "onshoring of these industries," and protecting "US national security and its defense and defense-adjacent industrial base."
