At issue is what is called uncoated groundwood paper, used in newsprint. US imports of it from Canada totaled USD 1.27 billion in 2016, the Commerce Department said.
The Americans argue that the Canadian paper has been sold in the country at less than its fair value.
The duties are preliminary pending more investigation and a final decision in August.
For now, US importers of this product will have to pay cash deposits equivalent to 22.16 per cent of the price of what they bring in from Canada.
The decision follows a complaint filed by a US firm, North Pacific Paper Company.
He has forced a renegotiation of the North American Free Trade Agreement with Canada and Mexico, arguing that it was a bad deal for the US.
Last week Trump gave Canada and Mexico a temporary exemption from new tariffs on steel and aluminum imports. But he said the tariffs would in fact be imposed if the NAFTA talks did not yield a deal that satisfied him.
"From January 20, 2017, through March 13, 2018, the Commerce Department has initiated 102 antidumping and countervailing duty investigations - a 96 percent increase from the same period in 2016-2017," he added.
This kind of paper was already hit by preliminary US countervailing duties announced in January.
Canada's government said it was "disappointed" by the new US measure.
"Any duties will have a direct and negative impact on US newspapers, especially those in small cities and towns, and result in job losses in the American printing sector," the foreign minister and minister of natural resources said in a statement.
The US announcement came as Canada's foreign minister, Chrystia Freeland, was in Washington to discuss bilateral trade relations.
