Industrial Clusters in India

How towns specialising in a single product, from Tiruppur's knitwear to Morbi's ceramics, became powerful manufacturing hubs, and the challenges they face.

Across India, many towns specialise in making particular products. These industrial clusters are groups of firms in the same industry located close together, often dominated by small and medium enterprises.

Famous clusters

Tiruppur, Tamil Nadu: knitwear and cotton garments, a major exporter of T-shirts and knitted clothing.
Morbi, Gujarat: ceramic tiles and sanitaryware, among the largest ceramic clusters in the world.
Ludhiana, Punjab: bicycles, bicycle parts, hosiery and machine tools.
Surat, Gujarat: diamond cutting and polishing, and synthetic textiles.
Moradabad, Uttar Pradesh: brassware and metal handicrafts.
Sivakasi, Tamil Nadu: fireworks, matches and printing.
Jalandhar, Punjab: sports goods.

Why clusters form and thrive

Specialised suppliers: firms can easily source inputs, machines and repair services.
Skilled labour pools: workers learn the trade and move between firms.
Knowledge spillovers: techniques and designs spread quickly.
Buyers: traders and exporters come to clusters to find many suppliers in one place.
Division of labour: small firms specialise in particular stages of production.

These are the agglomeration benefits described by economist Alfred Marshall.

Challenges

Pollution: many clusters, such as dyeing units in Tiruppur and ceramic kilns in Morbi, have faced environmental problems. Tiruppur’s dyeing units were ordered by courts to stop discharging untreated effluent, and the cluster adopted zero liquid discharge treatment.
Informal work and labour conditions.
Small firm size, limiting investment in technology.
Competition from other countries.
Infrastructure gaps in power, roads and logistics.

Policy support

India’s government has supported clusters through schemes offering common facilities, such as testing labs, design centres and effluent treatment plants, shared among many small firms.

Morbi's tiles

In Morbi, hundreds of ceramic factories sit close together. Clay suppliers, kiln makers, packaging firms and transporters all serve the cluster. A new firm can start quickly using local suppliers and skilled workers. Buyers from across India and abroad come to Morbi knowing they can find many producers. The cluster's shared ecosystem makes each firm more competitive.

Thinking small firms cannot compete globally

Clusters of small firms can compete internationally by sharing suppliers, skills and buyers. Tiruppur's knitwear exports show how clusters can succeed.

Key takeaways

Industrial clusters are groups of firms in the same industry located together.
Tiruppur, Morbi, Ludhiana, Surat and others specialise in particular products.
Specialised suppliers, skilled labour and knowledge spillovers help clusters thrive.
Pollution, informality and small firm size are key challenges.
