Transit declaration T1: what is it, how to apply, and how much does it cost?

What do a truck full of goods rushing through Poland and a Swiss watch that hasn’t yet arrived in a store have in common? They’re both on their way—and both require a T1 transit declaration.
This document isn’t just a formality: it allows goods to cross customs borders without customs clearance, maintaining logistics flexibility and government oversight. So what is a T1, when is it needed, who issues it, and what are the benefits of partnering with an experienced broker like TVL?

What is a T1 declaration?

A T1 declaration is a customs document that accompanies cargo during transportation within the EU or countries participating in a joint transit procedure. It is required in cases where the goods do not have EU status, meaning they were imported from outside the EU. With this document, goods can be transported without paying customs duties and VAT during transit until they arrive at the final destination customs office, where they will be properly cleared. The T1 declaration is part of the unified customs transit system, which simplifies and expedites international shipping, reducing risks for carriers and monitoring the legality of shipments.

Who can issue the document?

The T1 declaration can be issued by:

• forwarders or carriers with authorized consignor status, i.e., registered in the NCTS system;
  customs brokers acting on behalf of a client;
• legal entities or sole proprietors engaged in foreign economic activity with the appropriate authority or an agreement with a customs representative.

To issue the T1 declaration, you must have access to the NCTS, the appropriate technical resources, and financial guarantees—bank, monetary, or insurance—that cover potential customs risks during transit.

When is it required?

The T1 declaration is required in the following cases:

• when goods are imported from outside the EU and must transit through EU countries without customs clearance at the border;
• If the goods are moving from one customs warehouse to another within the EU but have not yet become customs-free;
• if the goods are leaving the customs zone but not cleared for export and must reach the final customs clearance point;
• in the case of transit through several countries.

How does the declaration process work?

It all starts with document preparation. What is required? An invoice, packing list, CMR or other transport document, certificates if available, and a power of attorney (if submitted through a broker).
The next step is filing the declaration through NCTS. This process occurs as follows: the customs representative or sender completes an electronic T1 document and submits it to the national customs service through the NCTS system. The system then assigns a unique MRN number, which confirms acceptance of the T1. This number should be included in the accompanying documents.
When the goods arrive at the destination customs office, the T1 is closed. Transit must be closed, otherwise the responsible party may be fined. And this cannot be allowed. Key Stages of T1 Registration
Registering a T1 is more than just a technical procedure; it’s a responsible process that requires careful preparation. Here are the key points to consider before submitting your declaration:

1. Checking the Status of Goods
   A T1 declaration is only required for goods that do not have EU goods status. It’s worth clarifying in advance whether a declaration is truly necessary—this will save time and money.
2. Determining the Route
   It’s important to know which countries the cargo will transit through, as the T1 declaration covers the entire route and is valid until the customs point of destination. If reloading or a change of transport is planned, this must be taken into account immediately.
3. Availability of a Customs Guarantee
   Without a financial guarantee, the declaration will not be activated. If the declaration is processed through a broker or logistics company (e.g., TVL), they will provide their guarantee. Otherwise, it must be issued separately.
4. Selecting the Responsible Party
   The party submitting the declaration is responsible for the timely closure of the transit. This may be either the shipper or the customs representative.
5. Preparing for T1 Closing
   You must coordinate with the destination customs office in advance how and where to close the T1. This is especially important if the cargo is going to a customs warehouse or a free trade zone.

How much does a T1 declaration cost?

The cost of processing a T1 depends on several factors:

• the complexity of the route;
• the number of goods;
• the need for a customs guarantee;
• the country of clearance.

The fee for a customs guarantee reaches 1-2% of the customs value of the goods, but brokers sometimes offer a fixed rate. Some companies include T1 in their package of services when arranging delivery, in which case the price is negotiated individually.
The T1 transit declaration, the cost of which depends on the complexity of the route, is processed only through the NCTS system.
