WASHINGTON, Aug 6 (Reuters) – President Donald Trump has signed an ​executive order outlining ‌new trade actions to protect the U.S. polysilicon manufacturing industry, a White ‌House ​aide said ⁠on Thursday without ⁠providing details.

The order lays out “a series of trade and tariff actions ​under Section 232, intended to ensure ⁠that domestic ⁠polysilicon manufacturing is ​properly supported and protected ​from overseas dumping and ‌offshore threats,” White House aide Will Scharf said.

Reuters previously reported ⁠the administration planned to impose 15% tariffs on imported ⁠polysilicon ‌derivatives as well ⁠as create a ​new ‌price floor.
