US President Donald Trump has signed an executive order that immediately doubles the tariffs on steel and aluminum imports to 50 percent. The UK, on the other hand, is still temporarily exempt, and its tariffs stay at 25 percent.

The exemption depends on a trade agreement between the UK and the US that was signed last month. The goal of the agreement is to get rid of all tariffs. The UK could have to pay the full 50 percent rate if the deal isn't done by July 9, according to BBC.

Officials in the UK say they are doing everything they can to make the agreement happen as soon as possible.
