No one expected penguins to bear the brunt of Liberation Day.

But among the barrage of tariffs set out by Donald Trump, the US also took aim at uninhabited islands, talked up American beef and turned its nose up at plastic eggs.

At first glance, newly imposed tariffs on countries such as China, the European Union, India and the UK stand out – ranging from 34% to 10% respectively.

But the president also imposed tariffs on dozens of tiny territories – some of which don’t even have human inhabitants.

One of those was the Heard and McDonald Islands, an external territory of Australia in the Antarctic that is inhabited only by penguins and seals.

Despite having no human residents – or imports and exports – the island now faces a 10% tariff for any goods bound for the US.

According to export data from the World Bank, the US imported $1.4m (£1m) of mainly “machinery and electrical” products from Heard Island and McDonald Islands in 2022.

Australian territory Norfolk Island, a volcanic island 600 miles east of Queensland, was also hit with a hefty 29% tariff on exports to the US. That’s much higher than mainland Australia, which had a 10% tariff imposed.

The news was met with confusion by some of Norfolk Island’s 2,188 residents.

“Norfolk Island is a little dot in the world,” Richard Cottle, owner of a concrete-mixing business on the island, said on Thursday.

Although the island does ship a modest amount of Kentia palm seeds abroad, this is typically worth less than $1m (£760,000) a year, with the products mostly going to Europe.

According to US government data, America has recorded trade deficits with Norfolk Island for the past three years.

Other tiny nations and territories were also hit with 10% tariffs, including Tokelau, a dependent territory of New Zealand, with a population of around 1,600 people, and the Cocos Islands, another territory of Australia, home to around 600 people.

Australian Prime Minister Anthony Albanese told reporters he had no explanation for the tariffs, calling them “unexpected” and “a bit strange”.

After announcing a 20% tariff against the European Union, Mr Trump’s secretary of commerce Howard Lutnick spoke to Fox News to try to explain what was behind the decision.

In a brief but bizarre rant, Mr Lutnick spoke about the bloc’s ban on imported chicken from the US.

“I mean European Union won’t take chicken from America,” he said.

“They will take lobsters from America… they hate our beef because our beef is beautiful and theirs is weak.”

The EU has a ban on chicken washed in chlorine – a practice that is approved by the United States Department of Agriculture.

Although US beef is not completely prohibited in Europe, any beef that has been treated with artificial growth hormones – which is legal in the US and common among producers – is banned by the EU.

Why was Russia exempt?

Russia was not on Mr Trump’s tariff list, despite his threat to introduce some on Russian oil imports last week.

The US president made the threat after telling NBC’s Kirsten Welker he was “very angry” and “pissed off” after Vladimir Putin criticised the credibility of Ukraine’s president Volodymyr Zelenskyy, as fragile peace negotiations are ongoing.
