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. Exporter's EORI number – EU economic operators register with the customs authority responsible for the place where they are established (Article 9 of the Union Customs Code). 5. Commodity code (CN/HS) for each item – it determines, for example, whether a licence is needed (e.g. for dual-use goods). 6. Authorisation for the customs agency – if the agency lodges the declaration on your behalf.

Stage 2: Customs declaration (AES/ECS System)

The declaration is lodged electronically in the Polish customs system (PUESC, AES – Automated Export System). It can be lodged by the exporter itself or by its customs representative, e.g. a customs agency (Article 18 of the Union Customs Code).

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 office of exit, e.g. Calais or a Polish port/terminal).

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 declaration – Regular use of a simplified declaration requires an authorisation from the customs authorities (Article 166 of the Union Customs Code).

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 "Release for the 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 goods are presented to customs at exit (Article 267 of the Union Customs Code) and their exit is recorded in the system, which notifies the Polish export office.

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

Step 6: Export confirmation (IE599 / CC599C)

When the Polish system receives confirmation from the border, it automatically generates the export confirmation message – formerly IE599, in the current AES/ECS2 PLUS system CC599C. It goes to the declarant (an agency passes it on to the exporter).

The export confirmation is the primary proof of export for the 0% VAT rate. The Polish VAT Act (Article 41(6) and (6a)) requires a document confirming export from the EU and names the message from the export system as one such document "in particular", so where it is missing, other evidence may be used under Polish VAT law.

How long does it take?

• Clearance time depends on the quality of the documents, the control route selected and the load on the system, so there are no fixed timings – a well-prepared declaration is usually handled quickly, while a physical inspection extends it.

Most common problems

1. No declaration ("Driver went without duty") – Worst-case scenario. The goods leave the EU without the required pre-departure declaration (Article 263 of the Union Customs Code), and you have no proof of export. 2. Customs inspection – 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 -> Release -> Exit from the EU -> export confirmation (IE599/CC599C) -> 0% VAT` Each stage is linked. A lost EAD or a wrong MRN may delay or block the export confirmation, causing tax issues.
