Hwashin and Seoyon E-Hwa Propose ₹1,370 Crore Automotive Component Investments in Tamil Nadu
Hwashin Automotive India and Seoyon E-Hwa Summit Automotive India have proposed investments totalling ₹1,370 crore in Tamil Nadu. Representatives of both companies met State Industries Minister S. Keerthana on November 11, 2026. They submitted letters of intent to the State government.
Hwashin has proposed ₹850 crore over five years. The funds will go towards research and development, advanced manufacturing technologies, localisation, production capacity expansion and new project development. The company has operated in the State since 2002 and has a manufacturing facility at SIPCOT Industrial Park, Irungattukottai.
Seoyon E-Hwa has proposed ₹520 crore for technology upgrades and business development. The company said its Tamil Nadu operations will continue to support the requirements of Hyundai Motor India Limited (HMIL) and other OEM customers. Both companies supply components to HMIL and other automotive OEMs.
Formal MoUs are expected to be signed at the upcoming Investment Conversion Conclave. The proposals remain subject to completion of formal investment agreements. The source does not give project locations beyond Irungattukottai, capacities or timelines. It also does not say whether the Seoyon investment is for a new or existing facility.
The proposals follow reports that Hwashin, Seoyon and Iwamet, which supply components to Hyundai and Kia, were exploring shifting proposed manufacturing investments to Andhra Pradesh. HMIL’s integrated facility near Chennai has an installed annual capacity of 8,24,000 vehicles. The meeting was also attended by S. Vijayakumar, Additional Chief Secretary, Industries, Investment Promotion and Commerce Department, and Deepak Jacob, MD and CEO of Guidance Tamil Nadu.
