Korea will submit an official written opinion to the United States this week regarding an act that excludes electric vehicles assembled outside of North America from tax credits, officials said Wednesday.

The U.S. Treasury Department is requesting public input on the Inflation Reduction Act (IRA) amid concerns that the law, signed by U.S. President Joe Biden in August, would place non-American carmakers at a competitive disadvantage. Two Korean carmakers ― Hyundai Motor and its smaller affiliate Kia ― make EVs at domestic plants for export to the U.S.

"We are working to provide official feedback regarding the issue this week. We've been thoroughly reviewing the matter, and having close consultations with experts and businesses," an official of Seoul's industry ministry said.

The deadline for the submission is Nov. 4 (U.S. time). (Yonhap)
