“At 25 per cent they can sort of get over that fence. At 50 per cent they can no longer get over the fence.” It was not immediately clear whether the 25 per cent tariff on aluminium imports would also be doubled. The steel and aluminium tariffs were enacted under trade laws rather than emergency powers, and were not among those struck down by the decision of the Court of International Trade this week. However, those levies – the so-called “reciprocal tariffs” – will remain in place while the government pursues an appeal that will almost certainly be decided by the Supreme Court. A federal appeals court agreed to temporarily preserve the tariffs – which include a 10 per cent levy on Australian goods – while the appeal is urgently held.
