Since the deal took effect in 2016 major European firms have rushed to do billions of dollars’ worth of business with Iran, and now thousands of jobs are at stake.
Many of those firms fear their business ties with the US could be at risk if they continue to do deals with Iran past a November deadline.
What can the EU do?
There is an existing EU “blocking statute”, from 1996, aimed at countering US sanctions linked to communist Cuba. Now EU officials say they are revamping the statute to avoid the latest US restrictions on firms doing business with Iran.
But there are doubts about the statute’s legal power. According to Reuters news agency, Shell and some other European firms with big operations in the US prefer to push for US waivers on a case-by-case basis.
US authorities have imposed hefty fines on banks for processing Iranian transactions, including UK-based Standard Chartered, HSBC and Lloyds.
France, Germany and the UK all say they remain committed to the nuclear deal with Iran and to expanding business ties, provided Iran sticks to its commitments.
Before the imposition of punitive sanctions on Iran in 2012 the EU was its biggest trade partner. In 2011 Iran had a big trade surplus with the EU. Trade slumped in 2012, but has been climbing back up since the 2015 deal.
EU exports to Iran in 2017 (goods and services) totalled €10.8bn ($12.9bn), and imports from Iran to the bloc were worth €10.1bn. The value of imports was nearly double the 2016 figure.
Most EU imports from Iran are energy-related – more than 75% is oil and other fuels.
EU exports to Iran are mainly machinery and transport equipment, followed by chemicals.
But trade with Iran makes up just 0.6% of the EU’s total global trade. Iran’s main trade partners are the United Arab Emirates and China, which account for 23.6% and 22.3% of the country’s total trade, according to the European Commission.
What are the big deals at risk?
Since the lifting of sanctions there have been major EU-Iran business deals, among them:
