Tamil Nadu contributes around 11.19% of India’s GDP and nearly 12.1% of its manufacturing output. With mature industry, robust infrastructure and a skilled workforce, it offers a stable platform for long-term investment and global supply-chain engagement.
A Broad and Balanced Economy
- The state’s growth is distributed across Chennai, Coimbatore, Hosur, Tiruppur, Madurai and Trichy, with each hub playing a distinct role
- Chennai has become Tamil Nadu’s technology capital, home to over 600 IT firms and a rapidly expanding cluster of over 250 Global Capability Centres (GCCs) as of 2025, with the number projected to reach 450+ by 2030
- Manufacturing remains dominant, over 40,000 factories employing 2.7 million workers, while IT, logistics, finance and higher education expand rapidly
- Agriculture remains integral as the upstream link to textiles, food-processing and export chains
Industry Highlights
- Automobiles & Components: The Chennai–Oragadam–Sriperumbudur belt produces nearly a third of India’s vehicles, with tier-1 players like Hyundai, Renault–Nissan, BMW and Daimler and hundreds of suppliers
- Electronics & Semiconductors: Tamil Nadu accounts for over one-third of India’s electronics exports. Global firms (Foxconn, Pegatron, Dell, Flex) operate large complexes; state policies now target higher value production
- Textiles & Apparel: In Tiruppur alone, exports exceed US$4 billion annually. The state’s textile belt (Tiruppur, Erode, and Coimbatore) makes almost one-third of India’s garments, supported by an integrated cotton-to-clothing chain
- Renewables: More than half of installed power capacity is wind and solar. Tamil Nadu contributes ~46% of India’s total wind-manufacturing capacity and is increasingly a destination for green-power intensive manufacturing
- Aerospace & Defence: Hosur and Coimbatore anchor the Defence Industrial Corridor, connecting public enterprises (HAL, BHEL) and private precision-engineering firms
- Information Technology & Start-ups: Under the Tamil Nadu Startup and Innovation Policy, Chennai and Coimbatore rank among India’s top ten start-up ecosystems, with strengths in fintech, health-tech and AI

- Guidance Tamil Nadu provides single-window access to 200+ services across 30+ departments, with Biz Buddy for issue resolution
- Social inclusion is embedded: Share of India’s women factory workers based in TN (≈42%) with targeted skill development
Infrastructure & Connectivity
- Ports: Chennai, Ennore (Kamarajar) and Tuticorin (VOC) serve container and automobile exports. A transshipment port at Enayam is in planning
- Airports: Chennai International is India’s 5th-busiest airport, plus Coimbatore, Madurai and Trichy support logistics and connectivity
- Roads & Rail: The Comprehensive Road Infrastructure Development Programme (CRIDP) links every district to ports and industrial corridors; dense rail & road connectivity accelerates goods movement
- Industrial Parks & Utilities: Every district hosts SIPCOT, SIDCO or private industrial parks with specialisations (Sriperumbudur – electronics; Tiruppur – textiles; Hosur – aerospace). ~58% of installed capacity is renewable, national leader in wind with frequent record peaks. The state’s Tertiary Treated Reverse Osmosis (TTRO) plants recycle industrial water, underpinning sustainability
Human Capital & Innovation
- Annually, Tamil Nadu produces over 500,000 graduates from 570+ engineering colleges and 30 universities. The Naan Mudhalvan programme connects students with industry in robotics, AI, electronics design and green energy
- The state’s Skills Development Corporation partners with Siemens, Foxconn and others to tailor training for tomorrow’s factory floors. R&D hubs (IIT Madras, Anna University) and global design centres (Hyundai, Saint-Gobain) are embedded in the ecosystem
Trade & Global Integration
- Tamil Nadu is among India’s top three exporting states. 10% of national exports pass through its ports, covering vehicles, garments, electronics and software
- It ranked #1 in NITI Aayog’s Export Preparedness Index 2022, reflecting logistical strength and institutional efficiency
