The INSTC (North–South corridor) and Georgia's place in it
The INSTC is often mentioned next to the Middle Corridor, but the two run in different directions and serve different trade. Here is what the INSTC is, its branches, why it is the busier route by tonnage yet only half-usable for Western-linked cargo, and where Georgia fits.
What the INSTC is
The INSTC (International North–South Transport Corridor) is a multimodal route launched in 2000 by Russia, Iran and India: Russia → Caspian → Iran → Bandar Abbas → India. By tonnage it is large — industry reports put it at roughly 26.9M tonnes in 2024 (up from ~16.3M in 2021), several times the Middle Corridor. But that volume is mostly bulk on the Russia–Iran–India axis, not East–West container traffic.
Three branches
| Branch | Route | Note |
|---|---|---|
| Western branch | Bandar Abbas → Tehran → Rasht → Astara → Baku → Caspian/Russia or Georgia | partly touches the Caucasus |
| Trans-Caspian | Ferry across the Caspian Sea | Iran ↔ Russia/Azerbaijan |
| Eastern branch | Overland via Turkmenistan and Kazakhstan | bypasses the western shore |
Where Georgia fits
The western branch can continue from Baku to the Caspian and onward — either north to Russia or west to Tbilisi and the Black Sea ports of Poti/Batumi. That is where the INSTC overlaps with the Middle Corridor's Caucasus leg. The key distinction: the INSTC is North–South (Russia/India), the Middle Corridor is East–West (China/EU) — so they mostly complement rather than compete.
Why it is only half-usable
The INSTC runs through Iran, and that is the catch: companies tied to Western banks and insurers cannot openly use Iranian transit under sanctions, and Iranian logistics can be inefficient and exposed to regional instability. For Western-linked cargo, the realistic non-Iran overland option to Europe is the Georgia–Caspian route — which is exactly why the Caucasus keeps its value even as the INSTC grows in tonnage.
Development prospects
Investment in the INSTC continues (missing rail links such as Rasht–Astara, new Caspian capacity), and for Russia–India trade it will keep growing. But sanctions cap its usefulness for Western-facing flows — so a share of that demand keeps looking for the neutral alternative, and Georgia benefits as the non-Iran, sanction-free link. See the UAE → EU route via Georgia for a related case.
What it means for your cargo
If your cargo must stay clear of Iranian transit, the INSTC is not your route — the Middle Corridor via Georgia is. ABU JORJIA plans the routing that fits your cargo, compliance and timing.
Summary
The INSTC is big by tonnage but narrow in use for Western-linked trade, and it runs North–South, not East–West. Georgia touches it only on the western branch — and gains from being the neutral, non-Iran alternative. ABU JORJIA arranges the route end to end — send a request.
