What is happening: US businesses were forced to pay $4.4 billion in September as a direct result of tariffs.
Year-on-year: These payments represented a 54% increase from September 2017. The total value of imports only rose by 10%.
Retaliation: Other nations have introduced retaliatory tariffs in response to the US, which has further affected exports. Exports subject to these types of tariffs have dropped 26% from September 2017 to 2018.
Tariffs: The last round of tariffs hit over $200B worth of goods imported from China, with 10% duties. This value will rise to 25% at the start of 2019.
October: October could see even bigger costs than September as the tariffs take full effect.
