The European Union is likely to impose tariffs on $4 billion of U.S. imports including planes and plane parts next week in retaliation over U.S. subsidies for aircraft maker Boeing, EU diplomats said Friday.
A majority of EU governments have already backed the tariffs, which are expected to be put in place after a meeting of EU trade ministers on Monday.
"I would expect the tariffs to be imposed next Tuesday or Wednesday," an EU diplomat said.
The move will echo U.S. tariffs on European goods over subsidies for Boeing's rival Airbus. Combined, the two cases represent the world's largest-ever corporate trade dispute.
The World Trade Organization (WTO) gave the EU the right to impose counter-measures, but the U.S. said that there was no legal basis for this and that, if the bloc chose to impose measures, it "will force a U.S. response."
The move puts the long-running transatlantic trade dispute on the radar of the next U.S. administration, whoever wins the closely fought election.
The EU could have acted at the end of October, just days before the U.S. election, but chose to delay in order to avoid potentially impacting the outcome. EU governments formally cleared the move on Tuesday, election day.
Tariffs are due to be placed on U.S. planes and parts, fruits, nuts and other farm produce, processed products such as orange juice, certain spirits and a range of other goods, from construction equipment to casino tables, diplomats said.
The European Commission said it was finalizing the process to exercise its retaliation rights in case no agreed solution could be found with Washington, including the immediate suspension of U.S. measures.
The United States Trade Representative had no immediate comment.
The U.S. already has tariffs on $7.5 billion of EU and British goods in relation to a parallel case over subsidies for European planemaker Airbus.
Chris Swonger, president and CEO of the Distilled Spirits Council of the U.S., said any tariffs on spirits would further devastate an industry that has already seen a 41% drop in U.S. whisky exports to Europe due to previous EU tariffs.
The tariffs also hand Britain, which left the EU this year, a delicate decision about whether to join its neighbors in imposing tariffs at a time when it is in the midst of trade negotiations with both the U.S. and the EU.
Britain's trade minister said last week it would "keep all options open" to ensure it can respond to U.S. tariffs on Scotch whisky and other industries. Britain is one of four Airbus partner nations alongside France, Germany and Spain.
