The White House issued a statement on the 6th saying that President Trump signed a proclamation on the same day, announcing the imposition of a 15% tariff on imported polysilicon derivatives and the establishment of a minimum import price mechanism for imported polysilicon and its derivatives.
The announcement stated that according to Section 232 of the Trade Expansion Act of 1962, the US will implement the above measures starting from 12:00 AM Eastern Time on December 4, 2026, to revitalize the US polysilicon industry. By introducing a minimum import price mechanism, any product priced below that level will be prevented from entering the US market.
According to the announcement, the minimum import price for imported polysilicon is set at $21 per kilogram (about 85.83 ringgit), for polysilicon ingots and wafers at $100 per kilogram, and for imported solar cells and solar modules at $0.22 and $0.38 per watt, respectively.
The announcement also states that the US Department of Commerce is authorized to establish an incentive program to promote the re-shoring of polysilicon and related product manufacturing to the US.
US Commerce Secretary Rutnik stated that while semiconductors and solar cells are indeed manufactured in the US, "we also need to bring the supply chain" back home.
He said: "We are setting prices so that China can no longer dump its products; at the same time, we are imposing tariffs to require production 'here.' We do have this industry domestically, but the scale is too small."
