India's exports to Russia grew from roughly USD 3 billion in FY 2020-21 to over USD 12 billion in FY 2024-25, a fourfold jump driven by pharma, engineering goods, and agri categories that used to lose out to European suppliers. Most of that new volume travels the standard Suez → Baltic route. But an increasing share moves through the International North-South Transport Corridor (INSTC), a multi-modal route through Iran and the Caspian Sea that shaves 10–15 days off the transit clock. This post is the field guide.
The physical route
INSTC is not a single line on a map. It is three modes stitched together across three countries.
- Sea leg: India to Iran. FOB Nhava Sheva (JNPT) or Mundra to Bandar Abbas on Iran's south coast. Roughly 8–10 days depending on service.
- Overland leg: Iran. Rail and road from Bandar Abbas up through Bandar-e Anzali (Iranian Caspian port) or over the Iranian rail network to the Caspian Sea. 4–6 days.
- Sea + rail leg: Caspian to Astrakhan. Caspian ferry to Astrakhan on the Russian side. Rail distribution from Astrakhan into the Russian interior: Moscow region, Kazan, Yekaterinburg. 3–5 days.
Total: 15–20 days depending on the specific segment mix. Compare against Suez → St. Petersburg: 25–30 days plus 3–5 days of onward rail distribution from Baltic ports to the Russian interior. The INSTC advantage is 40 %+ when the destination is Moscow-region or south-Russian markets.
The cost picture
Faster does not automatically mean cheaper. Multi-modal transit involves multiple handling operations, each with its own cost stack.
Suez route: single leg, single bill of lading, container never breaks bulk. Freight cost per 20-foot from JNPT to St. Petersburg runs roughly USD 2,200–2,800 depending on season and carrier. Handling at destination is at a single Baltic port.
INSTC route: three legs, three handling operations, three sets of documentation. Total freight per 20-foot to Astrakhan runs roughly USD 2,600–3,100, a 15–20 % premium over Suez. What you gain in transit time you pay for in handling.
So when does it make sense?
- Time-sensitive pharma consignments. Vitamins, wellness supplements, and API-grade material where inventory holding cost or shelf-life pressure makes the 10-day saving worth the freight premium.
- Interior-destination cargo. If the buyer is in Moscow region, Kazan, or Yekaterinburg, INSTC ends closer to the buyer than St. Petersburg does. Onward distribution from Astrakhan is faster and cheaper than rail-onward from Baltic ports.
- Congested Suez windows. When Suez congestion, Red Sea security disruption, or Panama constraint pushes the Suez-Baltic route past 35 days, INSTC becomes not just faster but competitively priced.
What still makes it hard
Three things.
1. Documentation is triple-layered. Each modal handoff is a re-documentation point. Bill of lading from India to Bandar Abbas. Iranian rail bill from Bandar Abbas to Caspian port. Caspian ferry bill from Iran to Astrakhan. Russian rail bill for onward. Any one misalignment holds the container.
2. Iranian sanctions exposure. Cargo transiting through Iran creates OFAC / EU / UK sanctions-list exposure that shippers must screen carefully. Dual-use categories are excluded from INSTC in practice. Every counterparty in the chain (including Iranian freight forwarders and Caspian ferry operators) must be screened against the four consolidated lists before booking.
3. Capacity is finite. INSTC's throughput was estimated at ~10 million tonnes per year in 2024. That is small relative to Suez. When usage spikes, INSTC gets congested faster than the sea route because rail and ferry capacity are less elastic.
What we do on the corridor
For every India-to-Russia enquiry we get, we quote both routes. Suez to St. Petersburg for cargo bound for the Baltic and northern-Russian markets. INSTC via Bandar Abbas and Astrakhan for interior-market cargo and time-sensitive pharma. We screen every counterparty in either chain against OFAC SDN, EU Consolidated, UK HM Treasury, and UN Consolidated before the proforma is issued. Rupee-Ruble settlement via the Special Rupee Vostro Account (SRVA) applies to both routes.
The corridor is not glamorous. It is stitched together across three jurisdictions and three modes and it will not replace the Suez route. What it will do, and what it is already doing, is give Indian exporters and Russian buyers a real time-and-margin advantage on the specific slice of trade where 15 days matters more than USD 400.
