Chennai (formerly Madras) is a major port city on India's south-eastern coast and the capital of Tamil Nadu state, with a population of approximately 10 million in the metropolitan area. It is a significant centre for manufacturing, IT services, and maritime trade, hosting the Port of Chennai and Ennore Port, both key gateways for petrochemical and container cargo.

Chennai gained specific relevance in the 2026 Iran conflict through the registration of House of Shipping Private Limited at a Chennai address. The company was designated by OFAC on 15 April 2026 as part of the Shamkhani Iranian oil-smuggling network, which used Indian corporate entities to route Iranian crude past US export controls.

The city's maritime infrastructure — including oil terminals, logistics firms, and shipping companies — makes it a hub for Gulf trade flows. Chennai-based shipping entities operate in tanker routes connecting the Persian Gulf to Indian refineries, creating a structural link between Chennai's commercial community and the Hormuz supply chains disrupted by the 2026 conflict.
