Chennai has long been recognized as the “Detroit of India,” owing to its extensive automotive and auto component ecosystem. Over time, however, the city has transcended its automotive identity to host a diverse portfolio of industries – from electronics and IT to renewable energy, aerospace, and pharmaceuticals.

According to the Department for Promotion of Industry and Internal Trade (DPIIT), Tamil Nadu is one of India’s leading FDI-receiving states; it ranked fifth nationally in FY 2024-25, receiving INR 311.03 billion in foreign equity inflows. Chennai accounts for a substantial share of these inflows due to its strategic coastal location, skilled workforce, and pro-business policies.

Major industries operating in the Chennai metropolitan area include automotive, electronics, IT and business process outsourcing (BPO), financial services, logistics, and renewable energy. Surrounding satellite towns such as Sriperumbudur, Oragadam, and Mahindra World City further extend the industrial footprint, offering plug-and-play infrastructure, connectivity to ports, and access to industrial land with state support.

Infrastructure and connectivity

Ports and maritime trade

Chennai’s maritime infrastructure anchors its export-oriented economy. The Chennai Port, India’s third-oldest port, began commercial operations in 1881. It is among the country’s busiest government-run ports, handling containerized, breakbulk, and automobile exports. Nearby, the Kamarajar (Ennore) Port functions as a deep-draft facility catering to bulk cargo, liquid fuels, and roll-on/roll-off (Ro-Ro) automobile shipments. Together, these twin ports give the city unmatched access to global shipping routes, including Southeast Asia, the Middle East, and East Africa.

Industrial estates and SEZs along the GST Road and NH 45 corridor enjoy direct connectivity to these ports, minimizing logistics turnaround time for exporters in electronics, automobiles, and engineering goods.

Airports and air cargo

Located in Tirusulam in Chengalpattu district, in the Greater Chennai Metropolitan Area, and around 21 km (13 mi) southwest of the city center, Chennai International Airport serves as a major passenger and cargo hub for southern India. Handling over 20 million passengers and nearly 400,000 tonnes of freight annually, the airport supports global connectivity for technology, manufacturing, and pharmaceutical firms.

To meet rising demand, a greenfield airport project at Parandur (Kanchipuram district) has been approved, though delays around land acquisition may push completion date to 2030. Spanning more than 4,500 acres – the new airport will handle up to 100 million passengers per year upon completion. It is expected to bolster Chennai’s logistics and MRO (maintenance, repair, overhaul) capabilities, reinforcing its attractiveness to high-tech and export-driven sectors.

Urban transit and industrial corridors

Chennai’s Phase II Metro expansion, covering 118.9 kilometers (73.9 mi), is under implementation and will significantly improve urban mobility and connectivity between industrial clusters, residential areas, and the airport.

The city also serves as the eastern gateway to the Chennai-Bengaluru Industrial Corridor (CBIC), one of India’s flagship infrastructure projects. This corridor connects Chennai to Bengaluru and extends toward Mumbai, forming part of the national industrial corridor network. The corridor integrates road, rail, and port infrastructure – helping industries around Sriperumbudur, Oragadam, and Ranipet move goods seamlessly across southern India.

Additionally, the Chennai Peripheral Ring Road (CPRR) and Outer Ring Road projects will decongest the city’s urban core and improve freight and multimodal logistics movement between ports (Ennore, Kattupalli) and industrial hubs (for example: Sriperumbudur and Oragadam).
