A T1 is the customs transit document that lets goods which are not in free circulation move between customs offices without being imported. No duty and no import VAT arise while the goods are travelling; a guarantee stands in their place until the operation is discharged. That last word is where most of the trouble on this document lives — a T1 that is never discharged comes back months later as a demand for the duty that was suspended.
This page covers what the document is, when you need one, who is responsible for it, how it differs from the other transit documents, and what actually goes wrong in practice.
When a T1 is required
A T1 declaration is used whenever non-Union goods move under the common transit or Union transit procedure. In day-to-day forwarding that means four situations:
- Goods heading for a third country. Cargo moving from Europe to Central Asia, or through Türkiye to the Gulf, is not imported into the countries it crosses.
- Port to inland customs office. A container discharged at a port and moved to an inland clearance point travels under transit, not under import.
- Movements to and from a bonded warehouse. Goods travel from the port to bonded storage, and later from the warehouse to the border, under transit.
- Triangular trade. Where goods are bought in one country and sold to a third, the intermediate country is only a point of passage — the structure is explained in our article on triangular trade.
If the goods are being imported at the point of arrival, you do not need a T1 — you need an import declaration. The T1 exists precisely to avoid that import.
T1, T2, TIR and ATA: which transit document applies
| Document | Covers | Typical use |
|---|---|---|
| T1 | Non-Union goods, duty suspended | The default transit document for goods not in free circulation |
| T2 / T2F | Union goods, preserving their status | Moving free-circulation goods across a non-Union territory |
| TIR Carnet | Road transit between TIR Convention parties | Routes outside the common transit area |
| ATA Carnet | Temporary admission | Exhibition goods, samples, professional equipment |
| National transit | Between two customs offices within one country | Port to bonded warehouse movements |
Between parties to the common transit system the T1 can continue as a single operation across borders, so a separate declaration and a separate guarantee are not needed in each intermediate country. Türkiye has been a party to the Common Transit Convention since 2012, which is what makes the Europe-Türkiye-Central Asia corridor workable on a single document.
Who is responsible for the T1
The holder of the procedure is responsible — the party in whose name the transit declaration is lodged. This is often the forwarder or a licensed customs agent rather than the seller or the buyer, and it matters because the holder is the one liable for the suspended duty if the operation is not discharged correctly.
Three parties have distinct roles:
- Holder of the procedure — lodges the declaration, provides the guarantee, carries the liability.
- Carrier — must present the goods intact, with seals unbroken, at the office of destination within the time limit.
- Consignee — presents the goods to the destination office so the operation can be discharged.
Where the transport and the customs work sit with different companies, this is the seam where discharge gets lost. We hold both in the same team for exactly that reason.
The guarantee
Because duty and VAT are suspended rather than waived, a guarantee covers the amount at risk for the duration of the movement. It can be a comprehensive guarantee held by the procedure holder or an individual guarantee for a single movement.
A comprehensive guarantee has a ceiling. On high-value goods a single large shipment can consume much of the available amount, and until an earlier operation is discharged that capacity stays blocked — which quietly limits how many shipments can be in transit at once. On regular flows this is worth planning rather than discovering.
Discharge: the part that goes wrong
A transit operation ends when the goods are presented at the office of destination and the declaration is properly discharged. Delivery alone is not enough. If the goods arrive but the office of destination never confirms the arrival, the operation stays open, the guarantee stays blocked, and the customs authority will in due course start an enquiry procedure and, failing proof, assess the duty against the holder.
What is on the document
The transit document — the transit accompanying document that travels with the goods — carries the MRN (Movement Reference Number), the offices of departure and destination, the guarantee reference, the time limit for presentation, seal numbers, and the description, quantity and value of the goods. The MRN is the number to quote when anyone asks about the status of a movement.
Declarations are lodged electronically through the national transit system; the paper that travels with the truck is an accompanying print, not the declaration itself.
T1 and export: a common confusion
An export T1 is not a separate document type. Where goods are exported and then move under transit, two things happen in sequence: an export declaration closes the export, and a transit declaration opens the movement. On a shipment leaving Türkiye for a third country through the EU, both exist and they are not interchangeable. Treating the T1 as the export document is one of the more frequent documentary errors we correct.
Equally, a T1 on import does not clear the goods. It moves them to the place where clearance will happen. The import declaration is still to come.
How we handle transit
- Transit declarations lodged and the guarantee arranged by our own team.
- Open positions monitored through to discharge, not to delivery.
- Full loads and groupage by road and sea.
- Combined structures with bonded warehousing: goods wait without being imported, then clear or re-export.
- Documentary structure for triangular trade.
- Corridors to Kazakhstan, Uzbekistan, Georgia and the Gulf.
The full service picture is on our transit freight page.
Where goods under transit need to wait without being imported, the next step is bonded storage: how duty and VAT stay suspended is set out in what is a bonded warehouse.
A transit declaration never travels alone on the road: the file also carries a CMR consignment note, and the package count, weight and description on the two documents have to agree.
Frequently asked questions
What is a T1 document?
It is the customs declaration used for the transit of goods that are not in free circulation. It allows the goods to move between customs offices without being imported, with duty and import VAT suspended and a guarantee provided in their place until the operation is discharged.
Is duty payable under a T1?
No. Because the goods are not imported, no customs duty or import VAT arises while they are in transit. A guarantee covers the suspended amount for the duration. Duty becomes payable only if the goods are later imported, or if the transit operation is not properly discharged.
Who is responsible for a T1 document?
The holder of the procedure — the party in whose name the declaration is lodged, usually the forwarder or a licensed customs agent. The holder provides the guarantee and carries the liability if the operation is not discharged. The carrier is responsible for presenting the goods intact and on time.
What is the difference between T1 and T2?
A T1 covers goods that are not in free circulation, with duty suspended. A T2 covers goods that are in free circulation and preserves that status while they cross a territory where it would otherwise be lost. The status of the goods, not the route, decides which applies.
Is a T1 the same as an export declaration?
No. They are separate documents with separate purposes. An export declaration closes the export; a transit declaration opens the movement of goods that have not been imported. On a shipment leaving for a third country both exist, in that order.
How long is a T1 valid?
The office of departure sets a time limit for presenting the goods at the office of destination, based on the route and the mode of transport. Exceeding it without explanation triggers an enquiry into the movement, so delays on the road need to be reported rather than absorbed.
What happens if a T1 is not discharged?
The operation stays open and the guarantee stays blocked. The customs authority starts an enquiry procedure, and if arrival cannot be proven the suspended duty is assessed against the holder of the procedure. This is why arrival has to be confirmed formally, not just physically.
Can goods under T1 be stored?
Yes. Goods can move under transit into a bonded warehouse, where they can wait without being imported. Duty and VAT remain deferred until the goods are released for free circulation or re-exported.
Is Türkiye part of the common transit system?
Yes, since 2012. This means a transit operation starting in Türkiye can continue as a single movement into the common transit area without a new declaration and a new guarantee at each border — which is what makes the Europe-Türkiye-Central Asia corridor practical on one document.
