The U.S. International Trade Commission announced Wednesday that there was no evidence that Canadian paper imports were hurting the U.S. industry, striking down a 17 percent tariff the Commerce Department had imposed in January and additional tariffs of up to 10 percent on several Canadian paper companies.

The announcement was an unexpected blow to the Trump administration, which has sought to pressure Canada into making concessions as part of the ongoing renegotiations of the North American Free Trade Agreement and now has less leverage to do that. It was a win for the U.S. newspaper industry, which uses the imported Canadian product to keep print costs low.
