UN/LOCODE INCCU · India · IMO-designated crew-change hub
Kolkata (ex Calcutta) is one of 115 ports named in IMO Circular MSC.1/Circ.1636 as a designated crew-change hub. Ports made the list on the basis of accessible international airports, established agent networks, welfare-centre infrastructure, and — during the pandemic — visa-facilitation frameworks that allowed sign-on and sign-off crew to transit without lengthy quarantine. That combination continues to make these ports the practical corridors most seafarers move through today.
Nearest major airport for crew changes is Netaji Subhash Chandra Bose International Airport (CCU), roughly 14 km from the port. Confirm the exact terminal handover point with the ship's agent — many hubs have multiple terminals with different immigration processes.
Kolkata (Calcutta), India's principal east-coast river port on the Hooghly, handles bulk, container, and break-bulk traffic. Shore leave follows the standard Indian procedure.
