Beyond Rail and Road: India’s Coastal Shipping and Inland Waterways as the Underutilised Third Modal Option for Industrial Freight
India moves less than 7% of freight by coastal shipping and inland waterways. At Rs 0.80–1.20/tkm, coastal shipping is the cheapest freight mode for routes above 800 km along the coastline. At Rs 0.60–1.00/tkm on developed waterway routes, inland waterways are cheaper still. 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 a combined approximately 180 to 200 million tonnes of freight annually — approximately 6 to 7 percent of total freight volume. 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 connecting waterway corridors to industrial hinterlands, and a policy environment that has historically favoured road and rail over water freight despite water’s dramatically lower cost per tonne-kilometre.
- Coastal shipping — movement of cargo between Indian ports along the coastline without entering international waters — operates under the Coastal Shipping Regulations and benefits from cabotage protections that require coastal cargo to be carried on Indian-flagged vessels or vessels chartered under Indian operators. The National Logistics Policy 2022 set a target of increasing India’s coastal shipping volume by 30 percent by 2030 — from approximately 80 million tonnes in FY2022-23. The major commodities moved by coastal shipping are coal (from Odisha and Jharkhand ports to southern and western coastal power plants), iron ore (from east coast mining ports to western coastal steel plants), finished steel, cement, petroleum products, and fertilisers. The freight cost for coastal shipping is approximately Rs 0.80 to 1.20 per tonne-kilometre — lower than rail (Rs 1.50 to 1.80/tkm) and dramatically lower than diesel road (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 three commercially active waterways are NW-1 (Ganga, Allahabad to Haldia, 1,620 km), NW-2 (Brahmaputra, Sadiya to Dhubri, 891 km), and NW-16 (Barak River, Assam). Combined, these three carry approximately 100 million tonnes per year — the majority on NW-1. The freight cost on developed inland waterway segments is approximately Rs 0.60 to 1.00 per tonne-kilometre — the lowest of any freight mode in India. NW-1’s JMVP (Jal Marg Vikas Project), funded partly by the World Bank, has deepened the Ganga channel to 3 metres draught over much of the Varanasi-to-Haldia stretch, enabling larger vessel movement and commercial barge services.
- The carbon intensity of coastal shipping and inland waterways is dramatically lower than road freight. India’s coastal cargo vessels — primarily bulk carriers and tankers — emit approximately 15 to 30 gCO₂ per tonne-kilometre, compared to diesel road’s 101 gCO₂/tkm and even electrified rail’s 11.5 gCO₂/tkm. The higher coastal/waterway CO₂/tkm versus electrified rail reflects ship engines’ use of bunker fuel (heavy fuel oil or marine diesel), which carries a higher emission factor than grid electricity. However, ammonia or LNG-powered vessels — which several Indian coastal operators are evaluating — can reduce marine freight emission intensity by 60 to 90 percent, approaching rail’s level at lower cost per tonne-kilometre than rail infrastructure requires.
- For Odisha’s aluminium cluster, coastal shipping offers a particularly compelling route for both inbound raw material (bauxite from coastal Odisha deposits to Angul and Jharsuguda alumina refineries via Paradip port and river tributaries) and outbound finished aluminium (to western India ports at Mundra, JNPT, and Cochin for export and domestic distribution). 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 aluminium-to-port rail siding at Jharsuguda or Angul combined with coastal shipping from Paradip to JNPT could reduce the landed logistics cost of aluminium reaching western India consumers by approximately 20 to 30 percent 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, not the industrial shipper’s. For CCTS and CBAM purposes, switching from road to coastal shipping reduces Scope 3 Category 9 emissions (downstream transport) for the industrial company — a voluntary reporting benefit rather than a mandatory compliance benefit. The direct compliance benefit is through logistics cost reduction (which improves EBITDA and reduces the need to raise product prices to cover CBAM certificate costs) rather than through a change in GEI measurement.
India’s freight modal split is dominated by road — approximately 70 percent of total freight volume — despite 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 before the railways arrived. The dominance of road is not a reflection of road’s inherent efficiency — road is structurally more expensive per tonne-kilometre than either rail or water freight for virtually all bulk commodity flows above 200 km. 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 sets specific targets for modal shift toward rail, coastal shipping, and inland waterways — recognising that India’s freight cost as a percentage of GDP (approximately 13 to 14 percent, versus 8 percent in the US and 7 to 8 percent in China) 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 National Logistics Policy’s coastal shipping target of 30 percent volume growth by 2030 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 — Key Industrial Freight Routes · April 2026
| Route | Distance | Mode Used Today | Coastal Option | 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 3m draught now available; cargo handling terminals need development at Varanasi, Patna |
| 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 |
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 approximately 2 to 2.5 million tonnes of primary aluminium annually — much of which is currently shipped by road or rail to western India consumers (particularly the automotive clusters at Pune, Surat, and Ahmedabad). Coastal shipping from Paradip to JNPT (Mumbai) would cost approximately Rs 1,200 to 1,400 per tonne at coastal freight rates — versus approximately Rs 2,000 to 2,800 per tonne by rail for the equivalent journey. The principal missing infrastructure link is a dedicated aluminium loading terminal at Paradip connected to Jharsuguda and Angul by rail siding — estimated at approximately Rs 300 to 600 crore. At 500,000 tonnes per year of aluminium shifted from rail/road to coastal shipping, the annual logistics saving would be approximately Rs 400 to 700 crore — a 6 to 12 month payback on the terminal investment. This is one of the highest-return unimplemented logistics investments 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 Merchant Shipping Act, 1958, and subsequent amendments. Indian cabotage law requires coastal cargo to be carried on Indian-flagged vessels or vessels chartered under the General License for Coastal Shipping. The Ministry of Ports, Shipping, and Waterways has relaxed cabotage restrictions for certain cargo categories — including containers and LNG — to increase competition and reduce rates. For bulk dry cargo (steel, aluminium, fertilisers), the standard cabotage requirement applies, though the ministry has mechanisms for granting foreign vessel licences when Indian fleet capacity is insufficient. Industrial shippers approaching coastal shipping for the first time should engage a coastal freight broker (several operate from Paradip, Vizag, JNPT, and Cochin) and a shipping company registered under DGFT’s General License for Coastal Shipping.
What is the draft limitation on India’s developed inland waterway segments and which industries can use them?
NW-1 (the Ganga, the most developed waterway) now has 3 metre draught available on the Varanasi-to-Haldia stretch following the JMVP project funded by the World Bank. This allows vessels of approximately 1,500 to 2,000 DWT capacity — suitable for containerised fertiliser, packaged food, cement, and some steel products (coil and rod in containers), but not for large open-bulk steel slabs or aluminium ingots which require vessels too large for the 3 metre draught. The practical industries for NW-1 are therefore: fertiliser (bagged products in containers), food grains, cement, petroleum products, and manufactured goods — not primary metals. NW-2 (Brahmaputra) has deeper natural draught in some sections but serves northeastern logistics rather than the primary industrial corridors. For primary metal (steel slabs, aluminium ingots, iron ore) the coastal shipping route is more relevant than inland waterways.
Does coastal shipping have a competitive advantage over rail for the JMVP project freight — or only over road?
Coastal shipping at Rs 0.80 to 1.20/tkm is competitive against electrified rail at Rs 1.50 to 1.80/tkm on long coastal routes above 800 to 1,000 km. However, coastal shipping’s competitive advantage comes with a significant transit time disadvantage — a coastal voyage from Paradip to JNPT takes approximately 4 to 6 days, versus 2 to 3 days by DFC-served rail or 3 to 4 days by road. For high-value-density cargo where working capital cost of the additional transit time is significant, rail or road retains advantages. For bulk commodity cargo (primary aluminium, iron ore, fertiliser) where the working capital cost of additional transit time is low, coastal shipping is economically superior to both road and rail on routes above approximately 1,000 km where the mode is geographically available.
