On 1 March, President Trump announced the imposition of additional import duties on EU exports of steel and aluminium to the United States. The import duties are set at 25% on steel and 10% on aluminium. As a response, the European Commission will bring forward in the next few days a proposal for countermeasures against the US, that are compatible with World Trade Organisation regulations, and aim to rebalance the situation.
