Middle Corridor Route 2026: Trans-Caspian Freight Guide

Key points

Route: China – Kazakhstan – Aktau or Kuryk – Caspian ferry – Baku (Alat) – Georgia – Turkey or the Black Sea.
Best block trains take 13–17 days; the target is a stable 10–12 days, but many shipments take longer.
Container traffic grew 36% in 2025, yet capacity is still far smaller than the northern route through Russia.
The Caspian leg, with limited vessels, weather and falling water levels, decides the transit time.
Avoiding Russia does not remove sanctions screening; every shipment is still checked.

What the Middle Corridor is

The Middle Corridor is a multimodal chain of rail, sea and road links between China and Europe that runs south of Russia. Trains leave Chinese hubs, cross into Kazakhstan at Khorgos–Altynkol or Alashankou–Dostyk, and run across the country to the Caspian ports of Aktau or Kuryk. Containers then cross the Caspian Sea by ferry or container ship to Baku's Alat port, continue by Azerbaijani rail into Georgia, and either take the Baku–Tbilisi–Kars railway into Turkey or go to the Georgian Black Sea ports of Poti and Batumi for shipping to Constanța in Romania or to Bulgaria. Kazakhstan, Azerbaijan and Georgia coordinate the route through the TITR International Association, set up in 2017.

Chinese hub to the borderBlock trains from hubs such as Xi'an run to Khorgos or Alashankou in Xinjiang.
First gauge changeAt Altynkol or Dostyk containers move from 1,435 mm standard gauge to 1,520 mm broad-gauge wagons, usually 1–3 days.
Across KazakhstanKazakh rail carries the containers west to Aktau or Kuryk on the Caspian coast.
Caspian crossingContainers are loaded onto ferries or feeder ships to Alat near Baku. Waiting for a vessel is the most common delay.
Azerbaijan and GeorgiaAzerbaijani and Georgian rail carry the cargo west on broad gauge towards Tbilisi.
Into Turkey or to the Black SeaEither the Baku–Tbilisi–Kars line with a second gauge change at Akhalkalaki, or Poti or Batumi for a Black Sea crossing to Romania or Bulgaria.
Final deliveryCustoms clearance in Turkey or the EU, or onward transit by truck under TIR or NCTS.

Leg	Key points	Main risk	What to plan
China – Kazakhstan border	Khorgos–Altynkol, Alashankou–Dostyk	Gauge-change queues in peak season	1–3 days for transfer
Kazakhstan rail	Lines to Aktau and Kuryk	Single-track sections, congestion	Book on a scheduled block train where possible
Caspian Sea	Aktau or Kuryk to Alat (Baku)	Limited vessels, storms, falling water levels, port waits	The widest buffer in the plan
Azerbaijan – Georgia	Rail via Tbilisi	Handovers between operators and customs systems	Clean, consistent documents
Georgia – Turkey or Black Sea	BTK via Akhalkalaki to Kars; or Poti/Batumi ports	Second gauge change or extra sea leg	Choose the exit by final destination

Capacity and transit times in 2026

Kazakhstan Railways said in September 2026 that the best block trains now reach Europe in 13–17 days, down from about 38 days, with a target of a stable 10–12 days to ports in Georgia and Turkey. In practice transits have ranged from about 14 to 60 days, because a delay at one link holds up the whole chain. According to Kazakh figures, container traffic rose 36% to about 77,000 TEU in 2025, while total cargo fell to about 4.1 million tonnes from 4.5 million in 2024 as the cargo mix changed. The transport ministry puts capacity at about 6 million tonnes and up to 182,000 containers a year. The northern China–Europe network ran 5,460 trains in the first quarter of 2026 alone.

Middle Corridor vs the northern route and sea

About 18–30+ days to Turkey or Europe; 13–17 days on the best block trains.
Avoids Russia and Belarus entirely.
Two gauge changes plus a Caspian sea leg, so more handling.
Smaller capacity and less predictable schedules.

Pros and cons for shippers

Pro: no transit through Russia or Belarus, which matters for many EU and Turkish buyers.
Pro: a direct land link to Turkey, the Caucasus and south-east Europe without going around Africa.
Pro: improving fast, with new berths, rail lines, vessels and digital customs links.
Pro: TIR trucks can use the same Caspian ferries for door-to-door service to Turkey.

Con: the Caspian crossing is a bottleneck, with limited vessels, storms and falling sea levels affecting port access.
Con: several borders and operators, different rail and customs systems and repeated handling.
Con: transit times are less predictable than the northern route.
Con: trade is unbalanced, with little cargo moving back from Europe to China, so some equipment returns empty.

Infrastructure projects to watch

In February 2026 the World Bank approved an $846 million guarantee for the 322 km Moiynty–Kyzylzhar line in Kazakhstan, which shortens the route by 149 km and allows double-stack container trains. At Aktau a container hub built with China's Lianyungang port is complete, dredging is planned for 2026 and a €35 million EBRD loan funds berth rebuilding and new cranes; at Kuryk dredging is complete. Kazakhstan is building new container vessels, and digital customs links have cut some processing from 8 hours to about 30 minutes. A third China–Kazakhstan rail crossing, Bakhty–Ayagoz, targets 2027.

Compliance, customs and documents

Going around Russia does not take a shipment out of sanctions rules. EU, US and UK enforcement focuses on goods re-exported to Russia through Central Asia and the Caucasus, so every party, HS code and final destination is screened. As of November 2026 routes through Iran carry war and sanctions risk and are not offered as a standard option. On arrival in Turkey, Chinese-origin goods pay customs duty plus additional customs duties and, for some products, anti-dumping duties, and 20% KDV import VAT on the total; a certificate of origin is strongly recommended. Goods for the EU need the importer's EORI and an ICS2 entry summary with a 6-digit HS code.

How Golden Way uses the Middle Corridor

Our China to Turkey and Europe service, using the Middle Corridor and TIR trucks, is running. Our Guangzhou warehouse collects from several suppliers, counts, photographs and consolidates the cargo, and checks invoices and packing lists so the documents match at every border. We choose rail, rail and ferry, or a TIR truck through the Caspian depending on cargo, deadline and destination, and tell you the typical range up front.

How long does the Middle Corridor take from China to Europe?

The best block trains take about 13–17 days. Many shipments take about 18–30 days or more because of waits at the Caspian crossing.

Is the Middle Corridor faster than shipping by sea?

Usually yes to Turkey and the Caucasus: about 18–30 days versus about 30–40 days by sea to Istanbul. It is less predictable than sea or the northern rail route.

What is the capacity of the Middle Corridor?
