On 18 July 2018, the Official Journal published Commission Implementing Regulation (EU) 2018/1013 of 17 July 2018 imposing provisional safeguard measures with regard to imports of certain steel products. On 26 March 2018, the Commission published a Notice of Initiation of a safeguard investigation concerning imports of 26 steel product categories (2018/C 111/10) in the Official Journal. The Commission decided to initiate the investigation in the light of sufficient evidence that imports of those products might cause or threaten to cause serious injury to the Union producers concerned. On 28 June, the investigation was extended to two additional product categories. There was also a high risk of further increase of imports resulting from trade diversion due to the measures against imports of steel adopted by the United States under Section 232 of the Trade Expansion Act of 1962 (‘Section 232’). The 28 product categories (‘the product concerned’ or the ‘product categories concerned’) are all covered by the steel surveillance mechanism introduced by the Commission in May 2016. They are also subject to the US tariff measures under Section 232.
