Under the Indian Constitution, maritime transport is placed under the Concurrent List (Entry 23). This creates a dual administrative structure for the port sector:
- Major Ports: These fall under the jurisdiction of the Central Government (Union Ministry of Ports, Shipping and Waterways). There are currently 13 Major Ports in India (12 government-owned and 1 corporate port).
- Non-Major Ports (Minor/Intermediate Ports): These fall under the jurisdiction of the respective maritime State Governments and Union Territories, managed through their State Maritime Boards. There are over 200 notified Non-Major Ports along India’s coastline.
Major Port Authorities Act, 2021
This act replaced the Major Port Trusts Act, 1963. It decentralized decision-making and infused professional governance into major ports by replacing the traditional “Port Trusts” with agile “Port Authority Boards.” The legislation grants autonomy to major ports in fixing tariffs, entering into Public-Private Partnership (PPP) contracts, and managing port lands, positioning them to compete effectively with private players.
Merchant Shipping Act, 1958
This serves as the primary legislative framework regulating Indian shipping, registration of vessels, safety parameters, and seafarer welfare, ensuring compliance with international maritime conventions.
Macro-Economic Significance and Multiplier Effect
Volume and Value of Maritime Trade
The port sector is the primary gateway for India’s international trade. It handles approximately 95% of the country’s trade by volume and roughly 68% by value.
Strategic Coastal Geography
India commands a coastline stretching 7,516.6 kilometers, encompassing 9 maritime states and 2 Union Territories. It sits adjacent to prominent international shipping lanes, notably the East-West Trans-Indian Ocean Route, linking East Asia and the Pacific with Europe and Africa.
Hinterland Development and Employment
Ports act as structural catalysts for industrialization. They support extensive backward linkages with the domestic manufacturing, thermal power, petroleum refining, and fertilizer sectors. The maritime sector accounts for thousands of direct and indirect jobs in coastal logistics, custom clearancing, stevedoring, and warehousing.

| New Mangalore Port | Western Coast | Karnataka | Deep-water all-weather port; handles iron ore concentrates, LPG, crude oil imports, and cashew exports. |
| Cochin Port | Western Coast | Kerala | Natural harbor situated on Willingdon Island; home to the International Container Transshipment Terminal (ICTT) at Vallarpadam. |
| V.O. Chidambaranar Port (Tuticorin) | Eastern Coast | Tamil Nadu | Artificial deep-sea port; acts as a major hub for coal imports, fertilizers, and trade traffic with Sri Lanka. |
| Chennai Port | Eastern Coast | Tamil Nadu | An artificial all-weather port; one of the oldest modern ports on the east coast, handling automobiles and containers. |
| Kamarajar Port (Ennore) | Eastern Coast | Tamil Nadu | India’s first corporatized major port; registered as a public company to handle coal requirements for state thermal power stations. |
| Visakhapatnam Port | Eastern Coast | Andhra Pradesh | Landlocked, deep natural harbor protected by the ‘Dolphin’s Nose’ hill projection; primary gateway for iron ore and petroleum products. |
| Paradip Port | Eastern Coast | Odisha | Deep-water, artificial port located at the confluence of the Mahanadi river; heavily handles iron ore, coal, and crude imports. |
| Syama Prasad Mookerjee Port (Kolkata-Haldia) | Eastern Coast | West Bengal | India’s only major riverine port system; features a twin dock system (Kolkata Dock System and Haldia Dock Complex) managing high siltation challenges. |
| Vadhanvan Port | Western Coast | Maharashtra | Approved as India’s 13th major port; designed as an ultra-deep-draft mega-port to accommodate mega-container vessels. |
Modernization Projects and Policy Initiatives
Sagarmala Programme
The flagship program of the Ministry of Ports, Shipping and Waterways aimed at promoting “Port-led Development” in India. It revolves around four strategic pillars:
- Port Modernization & New Port Development: Upgrading existing infrastructure and constructing new mega-ports like Vadhavan.
- Port Connectivity Enhancement: Connecting ports to hinterlands via heavy-haul rail (under DFCs), expressways, and inland waterways.
- Port-linked Industrialization: Developing Coastal Economic Zones (CEZs), Maritime Clusters, and Smart Industrial Port Cities.
- Coastal Community Development: Upgrading skills, promoting sustainable coastal fishing, and developing community infrastructure for coastal populations.
Maritime Amrit Kaal Vision 2047
A long-term blueprint outlining infrastructure targets for the Indian maritime sector by 2047. It focuses on elevating Indian ports to global standards, developing smart ports, expanding port capacities to over 10,000 Million Tonnes Per Annum (MTPA), and driving the decarbonization of maritime operations.
Green Shipping and Harbours: Maritime India Vision 2030
Targets the transformation of major ports into “Green Ports” by increasing the share of renewable energy in total port power consumption to over 60%. Key initiatives include installing shore-to-ship power supply systems, setting up LNG bunkering stations, and deploying electric/hybrid port crafts.
National Technology Centre for Ports, Waterways and Coasts (NTCPWC)
Established at IIT Madras under the Sagarmala programme, it acts as the technological arm of the ministry. It conducts research, modeling, and engineering solutions for port dredging, navigation channels, and oceanographic processes, reducing dependence on foreign consultants.
Structural Challenges and Bottlenecks
High Turnaround Time (TAT)
Turnaround time—the total time taken by a vessel from entry into port limits to its departure—remains higher at several Indian major ports compared to global benchmarks like Singapore or Shanghai. Delays are driven by legacy cargo handling equipment, custom clearance procedures, and manual documentation.
Draft Limitations
Most major Indian ports feature shallow drafts (water depth), ranging between 10 to 14 meters. This prevents next-generation Ultra Large Container Vessels (ULCVs) from berthing directly, forcing cargo to be transshipped through regional hubs like Colombo, Singapore, or Jebel Ali, which adds to logistics costs.
First and Last-Mile Connectivity
Inadequate highway lane capacity and rail-yard bottlenecks at the immediate periphery of ports cause cargo evacuation delays, resulting in container congestion at port terminals.
Regulatory Disparities with Non-Major Ports
Historically, Non-Major Ports enjoyed greater tariff flexibility and agile operational management under private concessionaires, leading to a steady diversion of market share from state-run Major Ports to private Minor Ports like Mundra.
Statistical Snapshot and Facts for Prelims
Mundra Port Status
Mundra Port in Gujarat, a non-major private port managed by the Adani Group, has evolved into the largest commercial port in India by cargo volume, highlighting the efficiency of the landlord port model in the private sector.
Landlord Port Model Adoption
JNPA (Jawaharlal Nehru Port Authority) became the first 100% Landlord Major Port in India. Under this economic model, the public port authority retains ownership of the port land and regulatory oversight, while private concessionaires manage terminal operations, berths, and cargo handling equipment.
National Logistics Portal (Marine) – NLP Marine
A single-window digital platform designed to connect all stakeholders across the maritime trade sector, including shipping lines, custom brokers, port authorities, and terminal operators. It aims to eliminate paperwork and lower transaction costs through digital documentation.
Vizhinjam International Transshipment Deepwater Multipurpose Seaport
Located in Kerala, this is India’s first greenfield deepwater transshipment port. Featuring a natural draft of over 18 meters close to the international shipping lane, it is structurally engineered to dock the world’s largest container ships, directly challenging international transshipment hubs.
