On September 1, 2026, Vietnamese EV giant VinFast received approval for phase 2 investment at its Thoothukudi (Tuticorin) factory in Tamil Nadu. The aim is to move a step beyond assembling imported kits, toward a setup that locally designs, develops, and produces vehicles dedicated to the Indian market. For Japanese auto parts makers, this is a moment when an emerging EV maker is moving local sourcing into full gear, offering material for reading which parts to get into and how. However, VinFast has not disclosed the investment amount, additional capacity, or timing, so reliable figures remain limited for now.
According to Autocar Professional, VinFast obtained phase 2 investment approval for the expansion of its Thoothukudi, Tamil Nadu factory. The company has laid out a policy of "designing, developing, and producing products for India tailored to Indian customer needs, with a higher localization rate." The VF 6 and VF 7 it currently sells are assembled from complete knock-down (CKD) kits, and it will continue supplying the Indian market through this CKD assembly for the time being. Meanwhile, the investment amount, the production capacity to be added, and the timing of the expansion are all undisclosed, and this article draws no firm conclusions on them.
CKD, assembling imported kits locally, allows a company to get to market quickly with limited investment, but since it depends on overseas sources for most parts, it's easily affected by pricing and tariffs. To be price-competitive in India, a company needs to source parts locally and adapt the design itself to India's road conditions, climate, and price range. VinFast's explicit statement that it will "raise the localization rate" is a declaration that it is tackling this structural challenge. The company is said, as of this report, to rank among the top five EV passenger car brands in India, and it has steered toward local development at a phase when it is going after volume.
VinFast has held procurement briefings in India and Vietnam attended by more than 300 Indian suppliers, seeking local sourcing partners for parts. What should be noted here is that this does not mean VinFast "already has a supply network of 300 companies"; rather, it is simply that participation in the briefing reached that scale. The accurate reading is that an emerging EV maker pursuing local development is broadly gathering candidate suppliers ahead of mass production, which suggests an opportunity for suppliers to make contact at an early stage.
The report frames this as a shift in VinFast's policy, moving from import dependence toward local production of India-specific vehicles. Since no specific investment scale or production plan has been disclosed, there is no public information to conclusively judge market reaction or evaluation. Here, we will stay within the bounds of the fact that "the company has announced local development of a dedicated model and secured approval for its second phase."
Emerging EV makers trying to raise their localization rate need proven parts suppliers. Getting involved from the design stage makes it easier for even a latecomer to become the standard choice. Japanese finished-vehicle makers are reported to be struggling, and a situation where three Japanese companies have fallen far behind local players in EV scooters exists as well, but the story is different for parts and batteries. A local player's battery takes India's first BIS certification Viewed together with this, there remains an opening for Japanese components, which have strengths in certification and quality, to get a foothold. The realistic next action is to first make contact through procurement briefings held by locally development-oriented makers like VinFast, and gauge which parts could be adopted.
As local production advances, the supply network in India thickens not only for parts but also for battery materials and the handling of used batteries. In India, the movement toward the launch of battery metal recycling (urban mining) is a sign that, behind the scenes of EV localization, sourcing and collection are beginning to connect. Rather than focusing only on which finished-vehicle maker wins or loses, a perspective that seeks openings for Japanese companies both upstream and downstream is needed.
VinFast's second-phase approval is a report from a stage where the investment amount and capacity are still undisclosed. Precisely because of this, waiting until the numbers are finalized will be too late. The next action Japanese parts and materials makers should take now is to participate early in supplier briefings held by emerging EV makers pursuing local development, and to confirm from the early design stage which vehicle models and processes their own parts could be adopted for. Rather than trying to win with a finished vehicle, getting inside a maker seeking to raise its localization rate is the more realistic path for a latecomer Japanese company.
