Building India's Electric Bus Supply Chain
TRBL's localisation strategy is grounded in PSR's Tier-1 supplier network. We progressively replace imports with India-sourced or India-built sub-systems across battery, body, BMS, e-axle, HVAC, glazing and trim.

Every localised supplier follows IATF 16949-aligned controls — quality is not negotiated down for cost.
Phased Roadmap
Localisation milestones are published per platform — transparent to customers, partners and policy bodies.
