US President Donald Trump signs an executive order aimed at protecting the domestic polysilicon industry, according to reports from Channel NewsAsia and The Globe and Mail. The measures included in the order focus on price supports and import restrictions for certain products made from polysilicon. The Globe and Mail reports that the executive order imposes a series of price floors, designed to set minimum pricing for relevant polysilicon-derived goods. It also describes a 15% tariff on products made from polysilicon, which would raise the cost of imported items relative to domestic supply. Channel NewsAsia similarly frames the order as protection for the US polysilicon sector, though details are presented with less emphasis on specific figures in its brief summary. Taken together, the coverage indicates the executive order combines minimum price mechanisms with tariff measures to strengthen the position of US producers. The reports do not provide additional information in the provided excerpts on timelines, enforcement agencies, expected impact on prices for downstream manufacturers, or responses from trading partners.
