The Trump administration originally imposed tariffs on a range of Canadian aluminum and steel in the summer of 2018, sparking a tense trade war.

In a statement, Lighthizer’s office said the United States is reinstating the 10 percent tariffs on non-alloyed unwrought aluminum because Canada was sending more aluminum to the U.S.

“In the time of a global pandemic and an economic crisis, the last thing Canadian and American workers need is new tariffs that will raise costs for manufacturers and consumers, impede the free flow of trade, and hurt provincial and state economies," she said in a statement.

Aluminum Association, a group representing producers of the metal, also said it opposed the tariffs, and disputed the idea that Canadian imports had surged.

The association said that while imports from Canada of unalloyed aluminum did increase during the first half of the year, that was offset by declines in alloyed aluminum imports from Canada.
