The European Union says it will start imposing duties from July on a list of US products, ratcheting up a transatlantic trade conflict after Washington imposed its own tariffs on incoming EU steel and aluminum. EU members have given broad support to a European Commission plan to set 25 percent duties on up to 2.8 billion euros ($3.3 billion) of US steel, agricultural and other products, including bourbon, peanut butter, cranberries, orange juice, jeans and motorcycles . EU exports that are now subject to US tariffs are worth 6.4 billion euros. “The Commission expects to conclude the relevant procedure in coordination with member states before the end of June so that the new duties start applying in July,” Commissioner Maros Sefcovic told a news conference on Wednesday. The European Union exported some 5.5 million tons of steel to the US last year. European steel producers are concerned about a loss of market access but also that steel from elsewhere will flood in. That plan also includes duties of between 10 and 50 percent on a further 3.6 billion euros of US imports in March 2021 or potentially sooner if the World Trade Organization has ruled the US measures illegal. US products on the list include orange juice, bourbon,and a variety of steel products. The European Union, Canada and Mexico have all responded after Trump last Friday ended their exemptions from tariffs of 25 percent for steel and 10 percent for aluminum. Canada has announced it will impose retaliatory tariffs on C$16.6 billion ($12.9 billion) worth of US exports from July 1. Mexico put tariffs on American products ranging from steel to pork and bourbon on Tuesday Some of the products chosen are designed to target states of senior Republicans who are seeking to retain control of both chambers of Congress in hotly contested November elections. The European Commission launched a legal challenge against the US tariffs at the World Trade Organization last Friday. It is also assessing the need for measures to prevent a surge of imports of steel and aluminum into Europe as non-EU exporters divert product initially bound for the United States. European Trade Commissioner Cecilia Malmstrom said on Monday that preliminary “safeguard” measures for steel could come as early as July.
