Chinese battery companies spy a South Korean loophole to skirt US subsidy rules
- Some US$4 billion of investments in new battery factories have been unveiled by Chinese companies and their Korean partners over the past four months
- The firms want to take advantage of Seoul’s free-trade agreement with the US so that they can qualify for tax breaks under the Inflation Reduction Act

Over the past four months, Chinese companies and their Korean partners have announced some 5.1 trillion won (US$4 billion) of investments in five new battery factories in South Korea. And at least one local government is in talks for more projects, officials from the Saemangeum Development and Investment Agency say.
Ningbo Ronbay New Energy Technology Co. announced last week that it had been approved to set up a factory in South Korea that will eventually produce about 73,000 tonnes of ternary precursors, an ingredient from which a cathode is formed, a year.
“The product produced by the company’s Korea base meet the relevant requirements for qualified key minerals in the IRA bill and can enjoy the benefit of tariff policies when exporting to European and US markets,” Ronbay New Energy said.
