Beyond Rail and Road: India’s Coastal Shipping and Inland Waterways as the Underutilised Third Modal Option for Industrial Freight
India moves a small single-digit share of freight by coastal shipping and inland waterways, depending on whether the metric is tonnes or tonne-kilometres. On long bulk routes, coastal shipping can be among the cheapest freight modes, often around Rs 0.80–1.20/tkm in favourable cases. On developed inland waterway routes, freight costs can fall below coastal and rail rates. For Odisha’s aluminium cluster, West Bengal’s steel industry, and Gulf of Khambhat chemicals, this mode is comprehensively underused relative to its cost and carbon potential.
Key Takeaways
- India’s coastal shipping and inland waterways move an estimated combined volume in the range of 180 to 200 million tonnes of freight annually, representing a small single-digit share of total freight. This compares to China (approximately 15 percent by coastal and river) and Europe (approximately 10 to 12 percent by waterway) for comparable economies with significant inland water and coastal geography. The low share in India reflects historical underinvestment in port draught and capacity, limited multi-modal terminal infrastructure and a policy environment that has historically favoured road and rail over water freight.
- Coastal shipping, which is the movement of cargo between Indian ports along the coastline without entering international waters, operates under the Coastal Shipping Regulations and cabotage frameworks, though various exemptions and licensing mechanisms exist. The National Logistics Policy 2022 outlines objectives to significantly increase India’s coastal shipping volume by 2030. The major commodities moved are coal, iron ore, finished steel, cement, petroleum products, and fertilisers. The freight cost for coastal shipping on long bulk routes is often around Rs 0.80 to 1.20 per tonne-kilometre in favourable cases. This is generally lower than rail (heuristically Rs 1.50 to 1.80/tkm) and dramatically lower than diesel road (heuristically Rs 2.80 to 3.80/tkm).
- Inland waterways transport operates on 111 designated National Waterways under the Inland Waterways Authority of India (IWAI). The most commercially important waterways include NW-1 (Ganga, Allahabad to Haldia, 1,620 km), NW-2 (Brahmaputra, Sadiya to Dhubri, 891 km), and NW-16 (Barak River, Assam). On developed inland waterway routes, freight costs can fall below coastal and rail rates. NW-1’s JMVP (Jal Marg Vikas Project), funded partly by the World Bank, has seen significant channel improvement and selected stretches with deeper draught, improving commercial barge viability.
- The carbon intensity of coastal shipping and inland waterways is dramatically lower than road freight. India’s coastal cargo vessels generally emit far less CO₂ per tonne-kilometre than road freight, though exact values vary heavily by vessel, load, and route. While illustrative ranges place coastal shipping around 15 to 30 gCO₂/tkm compared to diesel road’s ~101 gCO₂/tkm and electrified rail’s ~11.5 gCO₂/tkm, newer ammonia or LNG-powered vessels can reduce marine freight emission intensity by 60 to 90 percent.
- For Odisha’s aluminium cluster, coastal shipping offers a particularly compelling route. Vedanta’s Jharsuguda plant and NALCO’s Damanjodi refinery are both within viable rail-plus-coastal combination distance of Paradip, which is developing as one of India’s largest bulk cargo ports. A dedicated rail-and-port handling solution would require substantial capex, though the exact cost depends on alignment, land, and berth design. However, combined with coastal shipping from Paradip to JNPT, it could offer a short payback period under high utilisation scenarios and reduce landed logistics costs significantly versus the current all-road route.
- The CCTS Scope 1 boundary for coastal shipping is entirely outside the industrial plant’s gate-to-gate measurement boundary. Ship bunker fuel combustion is the shipping company’s Scope 1. For CCTS and CBAM purposes, switching from road to coastal shipping reduces Scope 3 emissions for the industrial company. The direct compliance benefit is through sheer logistics cost reduction (which improves EBITDA and absorbs other carbon costs) rather than through a direct change in GEI measurement.
India’s freight modal split is dominated by road accounting for roughly 70 percent of total freight volume. This is despite India having a 7,500 km coastline, two commercially developed major river systems (the Ganga-Brahmaputra network and the west coast estuaries) and a historical maritime trading culture that built cities at Surat, Calicut, Cochin, Mahabalipuram and Nagapattinam long before the railways arrived. The dominance of road is not a reflection of road’s inherent efficiency. On long bulk routes, road is structurally more expensive per tonne-kilometre than either rail or water freight. It is a reflection of road’s convenience, the absence of multi-modal terminal infrastructure that enables cargo to transfer efficiently between modes, and the inadequate maintenance of waterway channels and coastal port capacity for industrial-scale dry bulk cargo.
The National Logistics Policy 2022 outlines objectives for modal shift toward rail, coastal shipping, and inland waterways recognising that India’s logistics cost as a percentage of GDP is a direct competitiveness drag on industrial productivity. For sectors like steel, aluminium and fertilisers, where freight cost is a significant percentage of delivered product value, modal shift toward lower-cost water and rail modes is one of the most directly available cost reduction levers. The NLP’s coastal shipping volume growth ambitions and the IWAI’s NW-1 development programme provide the infrastructure and policy context within which industrial logistics planners should be evaluating water modal options.
Route-by-route coastal shipping opportunity: where the economics work
Coastal Shipping vs Road and Rail — Illustrative Scenario Estimates for Key Routes · July 2026
| Route | Distance | Mode Used Today | Coastal Option | Estimated Cost Saving | Key Constraint |
|---|---|---|---|---|---|
| Paradip (Odisha) → JNPT (Mumbai) — aluminium | ~2,200 km coastal | Road (part) + Rail (inefficient routing) | Coastal bulk carrier Paradip → JNPT | Rs 600–900/t saving vs current road/rail mix | Port draught improvement at Paradip for larger vessels; loading facility |
| Vizag → Hazira (Gujarat) — steel slabs/coils | ~2,100 km coastal | Rail (Visakhapatnam to Surat — long transit) | Coastal vessel Vizag → Hazira | Rs 400–700/t saving on coastal route | RINL Vizag already port-adjacent — coastal loading facility upgrade needed |
| Haldia (West Bengal) → Varanasi via NW-1 (Ganga) — fertilisers/agri | ~1,100 km waterway | Road | Inland waterway barge on NW-1 JMVP segment | Rs 1,200–1,800/t saving vs road | JMVP improved draught stretches available; cargo handling terminals need development |
| Kandla (Gujarat) → Cochin — DAP/MOP distribution | ~1,500 km coastal | Road/Rail mix | Coastal vessel or short-sea from import terminal | Rs 300–500/t saving | Scheduling — fertiliser is seasonal demand; coastal scheduling must align with planting windows |
| Mumbai/JNPT → Ennore (Chennai) — finished steel distribution | ~1,300 km coastal | Predominantly road | Coastal Ro-Ro or bulk vessel | Rs 400–600/t saving for flat products | Coastal Ro-Ro terminal infrastructure; vessel availability for coil cargo |
Note: The cost savings above are scenario estimates based on favourable routing and optimal vessel utilisation. Actual freight rates vary dynamically.
Why Odisha’s aluminium cluster is the highest-potential coastal shipping opportunity in India’s industrial sector. Odisha’s aluminium cluster — Vedanta Jharsuguda, NALCO Angul, Hindalco Hirakud, sits within 200 to 300 km of Paradip port, one of India’s three largest ports by cargo volume. Paradip is an all-weather deep-water port with 16-metre draught capability, a coal and iron ore berth, and ongoing capacity expansion under Sagarmala. The cluster produces roughly 2 to 2.5 million tonnes of primary aluminium annually much of which is currently shipped by road or rail to western India consumers. Coastal shipping from Paradip to JNPT (Mumbai) could cost roughly Rs 1,200 to 1,400 per tonne under optimal rates versus generally Rs 2,000 to 2,800 per tonne by rail for an equivalent journey. A dedicated rail-and-port handling solution would require substantial capex, though the exact cost depends on alignment, land, and berth design. The broader challenge is not just a loading terminal, but seamless rail connectivity, berth availability, and compatible vessel scheduling. However, if effectively executed, shifting significant volumes from rail/road to coastal shipping could offer a potentially short payback period under high utilisation scenarios. This remains one of the most compelling logistical shifts available in India’s aluminium sector.
Frequently Asked Questions
What are the regulatory requirements for coastal shipping of industrial goods in India?
Coastal shipping of goods between Indian ports is governed by the Coastal Shipping Regulations under the Coastal Shipping Act, 2025. Indian cabotage rules dictate that coastal cargo is generally carried on Indian-flagged vessels or vessels chartered under applicable regulatory licensing. While the general cabotage frameworks apply to bulk dry cargo (steel, aluminium, fertilisers), the Ministry of Ports, Shipping, and Waterways has mechanisms for granting foreign vessel exemptions when Indian fleet capacity is insufficient, and has previously relaxed restrictions for certain cargo categories like containers and LNG to increase competition. Industrial shippers approaching coastal shipping should engage a qualified coastal freight broker.
What is the draft limitation on India’s developed inland waterway segments and which industries can use them?
NW-1 (the Ganga) has seen significant channel improvements allowing deeper draughts (up to 3 metres) on select stretches between Varanasi and Haldia under the JMVP project. This allows suitably designed vessels (e.g., 1,500 to 2,000 DWT barges) to operate, making it practical for containerised fertiliser, packaged food, cement, and some steel products. However, continuous 3-metre draught is not available year-round across the entire route, making it less viable for very large open-bulk shipments of steel slabs or aluminium ingots. For large primary metal consignments, the coastal shipping route is typically more robust than inland waterways.
Does coastal shipping have a competitive advantage over rail for freight or only over road?
On long coastal routes (generally above 800 to 1,000 km), coastal shipping can often be cost-competitive against electrified rail and substantially cheaper than road. However, coastal shipping’s competitive cost comes with a transit time disadvantage. For instance, a coastal voyage from Paradip to JNPT may take 4 to 6 days, versus 2 to 3 days by DFC-served rail. For high-value cargo where the working capital cost of additional transit time is significant, rail or road may retain an overall advantage. For bulk commodity cargo (primary aluminium, iron ore, fertiliser) where working capital sensitivity is lower, coastal shipping can be economically superior when geography permits.
