Auto Components Industry

The Auto Components Industry is an integral part of the global automotive value chain, supplying essential systems and parts to Original Equipment Manufacturers (OEMs), Tier I/II suppliers, and the aftermarket. This sector supports a wide range of vehicles—from two-wheelers and passenger cars to commercial vehicles, electric vehicles (EVs), and off-road machinery.

In India, the industry is one of the largest globally, contributing significantly to manufacturing GDP, exports, and employment. It is diversified across OEM supply, aftermarket services, and exports, and is witnessing major shifts due to EV adoption, digitization, automation, and localization of supply chains.
