UPDATE 1-Senate finance chair says tariffs on steel, aluminum should go

Republican U.S. Senator Chuck Grassley on Wednesday called on the Trump administration to lift tariffs on steel and aluminum imports from Canada and Mexico before the U.S. Congress begins considering legislation to implement the new U.S.-Mexico-Canada (USMCA) trade deal.

The leaders of the three countries agreed on a deal to replace the North American Free Trade Agreement (NAFTA), which governs more than $1.2 trillion of mutual trade. The agreement must be approved by the U.S. Congress and Canadian and Mexican legislators before becoming law. "Unfortunately, our producers are unlikely to realize the market access promises of USMCA while the Section 232 tariffs on steel and aluminum imports from Canada and Mexico remain," Grassley, chairman of the Senate Finance Committee, said in a statement. Grassley's committee is in charge of shepherding the pact through approval in the Senate.

U.S. farmers, hardest hit by President Donald Trump's trade wars with China, a key buyer of American agricultural products, as well as Mexico and Canada, have long complained that with tariffs remaining in place, they will not be able to seize the full benefits of the new trade deal. "Before Congress considers legislation to implement USMCA, the Administration should lift tariffs on steel and aluminum imports from our top two trading partners and secure the elimination of retaliatory tariffs that stand to wipe out gains our farmers have made over the past two and a half decades," Grassley said.

Trump had vowed to revamp NAFTA during his 2016 presidential campaign. At times during the USMCA negotiations, he threatened to tear it up and withdraw the United States from the pact completely, which would have left trade among the three neighbors in disarray.
