Australia’s federal government has reportedly revoked plans to impose hefty new tariffs on imported steel products used in large-scale solar projects, reversing a decision that had threatened to cause delays and blow out construction costs, including for some projects already underway.
Industry minister Tim Ayres, as reported by Renew Economy, in June agreed to impose a 48 per cent duty on hollow steel tubing – including those used in torque tubes that support the mounting of solar modules – imported from China, Taiwan, Malaysia and South Korea.
The contentious anti-dumping decision – which drew immediate howls from the solar industry, and then in September a written request for a review – was to be made retrospective to September last year, taking in multiple gigawatts of recently completed solar projects, as well as others about to start construction.
The September letter, authored by solar tracking specialists Nextpower and co-signed by a raft of developers including OX2, Lightsource, European Energy, and Pacific Energy, argued that the imported steel tubing is a crucial part of the supply chain that cannot be met adeqautely by Australian manufacturing.
“We are concerned that, without a clear distinction between genuine circumvention and downstream fabrication that is integral to project delivery, the expanded measures will produce serious collateral harm,” the letter said.
The letter also warned that a failure to reverse or amend the ruling would lead to “reduced investment confidence across Australia’s renewable energy pipeline; and broader impacts on the energy transition outcomes the government is actively working to accelerate.”
“These are not speculative risks,” it said. “They are the direct and near-term consequences for projects that are already underway, many of which cannot readily be re-specified or resourced without significant disruption and cost.”
Ayers, it appears, has heeded the industry’s message, the minister agreeing this week to revoke the June 2026 decision extending anti-dumping measures to drilled torque tubes, with the original duty notices remaining unchanged.
The reversal of the decision will also have retrospective effect, Nextpower Australia managing director Peter Wheale told Renew Economy on Thursday, removing the additional measures as introduced from September 04, 2025.
“I am incredibly pleased to advise – on 5 November 2026, the Australian Minister for Industry formally accepted the Anti-Dumping Review Panel’s recommendation following Nextpower’s appeal,” Wheal said in a message.
Renew Economy is seeking confirmation and comment from minister Ayers’ office.
Wheal says the terms of the reversal provides a strong basis for solar developers and suppliers to recover any duties already paid, as well as to release existing securities and withdraw or reassess outstanding duty demands.
It’s not yet clear why Ayers decided to reverse this particular decision on anti-dumping, but driving up the cost of a major component of solar farm construction is in direct conflict with one of his government’s flagship policies, Solar Sunshot.
The $800 million Solar Sunshot scheme, headed up by Arena, has a two-pronged goal of helping Australia to get a foothold in the global solar supply chain, while also working to further drive down the levelised cost of solar energy.
As Arena told Renew Economy last month, the pursuit of ultra-low cost solar is making “good progress” at the panel and cell level, but there’s a “long way to go” when it comes to driving down construction costs for utility-scale PV.
Dan Sturrock, Arena’s general manager of solar investment, says a key goal of the latest round of funding is to support cheaper construction methods and system integration, including the price of racking.
