#TrumpTariffs US President Donald Trump has doubled US tariffs on steel and aluminium imports to 50% - but the UK will not initially face the higher rate.
Since taking office in January, Trump has announced a series of import taxes on goods from other countries - arguing they will boost American manufacturing and protect jobs.
The move has thrown the world economy into chaos and critics have warned that tariffs are making products more expensive for US consumers.
What tariffs has Trump announced?
Steel and aluminium:
A 25% import tax on all steel and aluminium entering the US - including products made from these metals - took effect on 12 March.
On 4 June, the rate was doubled to 50%.
The UK has been temporarily exempted from the higher rate, because of a deal signed with the Trump administration in May, which would see the steel and aluminium levy axed altogether.
However, Trump warned the UK could end up paying the higher rate "on or after July 9" if the agreement is not fully implemented.
The US is the biggest importer of steel in the world after the European Union, getting most of the metal from Canada, Brazil, Mexico and South Korea.

European Union (EU):
Trump initially proposed a 20% tariff on most EU goods, but halved it to 10% until 8 July to allow time for trade talks.
At the end of May he expressed frustration with the lack of progress and threatened to introduce a higher rate of 50% rate on 1 June.
He later said he would extend this deadline to 9 July
