The European Commission has imposed anti-dumping duties on imports of hot rolled flat steel products from Brazil, Iran, Russia and Ukraine.
Hot-rolled flat steel is used in gas containers, pressure vessels, energy pipelines, tubes and shipbuilding.
The four countries will face duties ranging between €17.6 (£15.7) and €96.5 (£86) per tonne following an investigation by the Commission.
The latest measure takes the total number of anti-dumping and anti-subsidy measures in place on steel products to 48.
The Commission said: “The goal is to provide a level playing field and conditions of fair competition for European companies.”
