Export customs clearance in Poland – step by step [Procedure 2026]

Sending goods to the United Kingdom (and any other non-EU country) begins with export clearance. This is the moment you declare goods for export and the Customs Authority gives the "green light" to leave the European Union.

Without proper export clearance you will not only be unable to legally export goods, but above all you will not be entitled to the 0% VAT rate in export. How does this process work in practice?

Step 1: Document preparation

Before the goods leave the warehouse, you must complete documents for the customs agent. Do not wait for the driver to arrive – send documents by email in advance.

Required set: 1. commercial invoice (or proforma for free goods). 2. Consignment note (CMR) – may be preliminary, including driver and vehicle data. 3. Packing List (goods specification) – net/gross weights, number of packages. 4. Authorisation for customs agency – one-off or permanent, registered in PUESC.

Stage 2: Customs declaration (AES/ECS System)

The customs agency sends the declaration electronically to the system AES (Automated Export System).

In this declaration, the following is declared:

• Who sends and who receives (EORI).
• What kind of goods (CN codes).
• Where the goods leave the Union (Customs Exit Office, e.g. Calais/Dover or Polish port).

Important: Clearance can be conducted in two modes: 1. Standard clearance – Goods must be available for inspection at a location recognised by the Customs Office (e.g. customs branch or company warehouse if authorised as a recognised location). 2. Simplified clearance – For trusted entities, allows faster release of goods (often within 30-60 minutes).

Step 3: Assigning MRN number and EAD document

After submission, the system generates a number MRN (Movement Reference Number). This is the key number of your shipment.

The agency sends you the document EAD (Export Accompanying Document) – a document with a barcode and MRN number.

• You print the EAD and hand it to the driver.
• The driver must carry this document to present at the EU exit border (e.g. in France before boarding the ferry/tunnel).

Stage 4: Release of goods for export procedure

When the Customs Office accepts the declaration (and possibly conducts an inspection if the system selects a control), you receive a message "Exemption to export procedure". Only at this point can the goods physically start their journey.

> Note: Departure of goods before receiving clearance is a violation of customs regulations!

Stage 5: Removal of goods from the EU (Border)

The driver proceeds to the external EU border (e.g. Calais Terminal). There, the EAD document (MRN) is scanned. The customs system at the border (e.g. French SI Brexit system) sends a message to the Polish system: "Goods with MRN number... have just left the Union".

This is a key moment. The "scan" at the border closes the export procedure.

Step 6: IE599 message (Final)

When the Polish system receives confirmation from the border, it automatically generates a message. IE599 (Proof of Export). It goes to the customs agency, which then sends it to you (usually as an XML file + PDF visualisation).

IE599 is your "holy grail". This is the only document that gives you 100% certainty that you can apply the 0% VAT rate in your tax settlement with the Tax Office.

How long does it take?

• Preparing the declaration: 15-60 minutes (depending on the agency's efficiency and the quality of your invoice).
• Waiting for release:
• Standard mode: 1 to 4 hours (usually).
• Simplified mode: approx. 30 minutes.
• Obtaining IE599: A few minutes after the driver crosses the border (if systems operate correctly).

Most common problems

1. No declaration ("Driver went without duty") – Worst-case scenario. The goods are in the UK but were not declared in Poland. Retrospective legalisation is difficult and costly. 2. Clearance at the wrong location – Customs clearance cannot be performed in PL if the goods are already in Germany. 3. Customs audit – Sometimes the Authority wants to see the goods. If the vehicle is loaded "to the roof" and there is no access to the pallets, there may be a problem.

Summary

The export procedure sequence is: `Declaration -> MRN/EAD -> Departure (Border scan) -> IE599 -> 0% VAT` Each stage is linked. Losing the EAD by the driver may result in no border scan and no IE599, causing tax issues.
