The U.S. is moving to impose additional tariffs of up to 50% on a slate of Canadian imports, senior Trump administration officials said, per CNBC.

Officials described the measures as retaliation for what Washington calls persistent trade discrimination against key U.S. products and industries.

President Donald Trump has signed three separate proclamations targeting different categories of Canadian goods with the new duties, according to officials who briefed reporters.

The tariffs are being imposed under Section 338 of the Tariff Act of 1930, which allows the president to levy "new or additional duties" of up to 50% on imports from countries that discriminate against U.S. commerce.

The new rates are scheduled to take effect 30 days after the proclamations are signed.

Targeted Products and Sectors

Each proclamation covers a different set of Canadian exports, ranging from consumer goods such as wine and hockey sticks to industrial products like cement, officials said.

"By doing this, President Trump is leveling the playing field for crucial American exports: motor vehicles, alcohol, and dairy," a Trump official said on a call with reporters, per CNBC.

One official said Canada "has to be held accountable for this continued discrimination," framing the move as part of a broader effort to force changes in Ottawa’s trade practices.
