Australia’s government said it will “examine all options” after US President Donald Trump imposed a 15 percent tariff on foreign imports.

“We have consistently advocated against these unjustified tariffs,” Australian Trade Minister Don Farrell said in a statement Sunday. “We are working closely with our Embassy in Washington to assess the implications and examine all options.”

Trump announced the 15 percent rate one day after revealing a 10 percent global tariff on overseas goods on Friday. Both announcements followed a ruling from the US Supreme Court that Trump’s mechanism for applying earlier tariffs was illegal. Under that regime, Australia received the baseline tariff of 10 percent.

The initial 10 percent tariffs Trump announced on Friday were scheduled to go into effect on Tuesday at 12:01 am Washington time. It’s not immediately clear when the 15 percent tariff would take effect.
