Brussels (AFP) - The EU on Wednesday said a raft of retaliatory tariffs, including on whiskey and motorcycles, against painful metals duties imposed by the US would be ready as early as July.

The European Commission, which handles trade matters for the 28-country bloc, "expects to conclude the relevant procedure in coordination with member states before the end of June," said European Commission Vice-President Maros Sefcovic at a news briefing.

This would allow "that the new duties start applying in July," he added.

"It is a measured and proportionate response to the unilateral and illegal decision taken by the US to impose tariffs on the European steel and aluminium exports which we regret," said the former Slovak prime minister.

From blue jeans to motorbikes and whiskey, the EU's hit-list of products targeted for tariffs with the US reads like a catalogue of emblematic American exports.

The European Union originally drew up the list in March but pledged not activate it unless US President Donald Trump followed through on his threat to impose 25 percent tariffs on steel imports and 10 percent on aluminium.
