Adjusting Imports of Polysilicon and Its Derivatives Into the United States

This proclamation imposes minimum import prices (MIPs) and a 15% ad valorem tariff on polysilicon and downstream derivatives (ingots, wafers, solar cells, modules) effective December 4, 2026, to protect U.S. production capacity for semiconductor and solar supply chains. It also establishes an onshoring incentive program with construction deadlines by January 20, 2029, and includes differentiated tariff treatment for certain trading partners including the UK (10% rate) and EU/Japan/Korea/Taiwan/Switzerland/Liechtenstein (capped at 15% combined with Column 1 duties).

Imposing Additional Duties To Offset Canadian Discrimination Against the Commerce of the United States With Respect to Motor Vehicles

This proclamation imposes an additional 50 percent ad valorem duty on certain Canadian products, effective August 19, 2026, to offset Canada's discriminatory tariff scheme against U.S. motor vehicles. The action uses Section 338 of the Tariff Act of 1930 to retaliate against Canadian tariffs and tariff-rate quotas that apply only to U.S. auto exports, which have allegedly caused a 22 percent drop in U.S. vehicle exports to Canada.
