Ronbay's main production sites are in Ezhou, Xiantao and Zunyi in China, as well as in Chungju, South Korea.47 In 2022, the company began building further production sites in South Korea to circumvent U.S. trade restrictions put in place by the Inflation Reduction Act.89 It also announced plans to expand into Indonesia10 and Poland.11
