US President Donald Trump’s 50% tariff on goods from commodities powerhouse Brazil is upending crop markets, sending orange juice prices tumbling and coffee rising.

The order entails an additional 40% tariff on the 10% duties already being levied, but energy products would be exempt.

Now, as the 90-day pause on those and other targeted US tariffs is set to expire, Trump has raised Brazil's rate to a whopping 50% – potentially launching a trade war with Latin America's biggest economy, which sells large amounts of beef, coffee, steel and other products to the United States.
