India’s chemical sector is a diversified powerhouse that has expanded steadily in recent years and is expected to surpass US $300 billion before 2028. India is already the world’s sixth-largest producer, proving its importance in international supply chains. The sector employs over two million people and benefits from highly concentrated manufacturing clusters in Gujarat and Maharashtra that offer integrated feed-stock pipelines, port access and common-effluent facilities. Liberalized FDI rules and free-trade agreements are further accelerating investment, positioning India as a preferred chemicals hub. 24 × 7 reactors, distillation columns, and large dryers burn through significant coal, oil or gas, so energy outlays are extremely high.
