The European Union on Wednesday voted to approve its first set of retaliatory measures to counter tariffs imposed by the U.S. on steel and aluminum.

The European Commission, the bloc’s executive arm, said duties would start being collected on a first tranche of tariffs on U.S. imports from April 15, with a second set of measures following on May 15. According to a draft document seen by CNBC in March, the tariffs target a wide range of goods, including poultry, grains, clothing and metals. The EU has not released a final list of impacted products, and declined to comment further on Wednesday.
