Since taking office in January, Trump has announced a series of import taxes on goods from other countries, arguing that they will boost American manufacturing and protect jobs.

The measure has thrown the global economy into turmoil, and critics have warned that the tariffs are making products more expensive for American consumers.

Tariffs are taxes levied on goods purchased from other countries.

They are typically a percentage of a product's value.

A 10% tariff means that a $10 product would have an additional $1 tax imposed on it, bringing the total cost to $11 (£8.35).

Companies that import foreign goods into the United States must pay taxes to the government.

They can pass on some or all of the additional cost to customers. Companies can also decide to import fewer goods.
