US President Donald Trump has signed an executive order doubling US tariffs on steel and aluminium imports to 50%, but the UK is temporarily exempted.
The order signed by Trump raises import taxes for US-based firms buying from other countries from today, but the levy remains at 25% for British firms.
The order depends on the UK and US tariff deal signed last month, which would see steel and aluminium levies axed.
However, the agreement is yet to come into force, meaning UK steel exporters face tariffs until then and could face a higher amount if the pact falters.
