Customs Procedure 42 and Export - Complications with MRN Closure

Updated: April 2026Reading time: ~8 min

Procedure 42 is a customs procedure used when importing goods into the EU with a VAT exemption, where the goods are immediately dispatched to another Member State (intra-community supply). But what happens when these same goods are subsequently exported outside the EU? In many cases, complications with MRN closure arise - especially when the export declaration is filed in a different country than the port through which the goods actually leave the EU.

What is Customs Procedure 42?

Procedure 42 (Customs Procedure 42) is an import procedure in which goods from outside the EU are customs cleared in one Member State but are exempt from import VAT because they will be immediately delivered to a recipient in another EU country as part of an intra-community supply of goods.

The procedure code in the import declaration is 42 00. The legal basis for the VAT exemption is the VAT Directive (2006/112/EC), and the customs procedure is regulated by the Union Customs Code (Regulation 952/2013) and its implementing provisions.

A typical scenario: goods from China are customs cleared in Rotterdam (Netherlands), but are immediately transported to a recipient in Poland. The importer pays customs duty but does not pay Dutch VAT - because the goods are the subject of an intra-community supply. VAT will be settled in Poland by the buyer.

When Does Procedure 42 Affect Export?

Procedure 42 itself is an import procedure - it has no direct connection to export. The problem appears in a specific but common scenario:

  1. Goods are imported into the EU under Procedure 42 - e.g., customs clearance in the Netherlands, delivery to Poland
  2. In Poland, the goods are processed, repacked, or stored
  3. The goods are then exported outside the EU - e.g., shipped to a customer in Turkey, the United Kingdom, or the USA

At this point, the question arises: in which country should the export declaration be filed? And through which port will the goods actually leave the EU? When these two elements are not synchronized - the MRN may remain open.

Important distinction: The MRN complications do not result from Procedure 42 itself, but from the fact that the goods have passed through two EU countries (import in one, export from the other). This means the customs systems of two countries are involved, increasing the risk of communication and routing problems with the declaration.

Typical MRN Problems When Exporting Goods from Procedure 42

  • Incorrect customs office of exit code - the export declaration was filed in Poland, but the customs office of exit code does not correspond to the port through which the goods actually departed. The declaration is routed to the wrong customs office, which does not see the goods.
  • Lack of communication between customs systems - the export declaration filed in the Polish customs system must be forwarded to the customs system of the country through which the goods leave the EU (e.g., Germany, the Netherlands, Belgium). This communication can fail or be delayed.
  • Incorrect assignment of the country of export - when goods were imported in one country and are being exported from another, questions may arise about which country is the “country of export” within the meaning of customs regulations. An incorrect determination affects the routing of the entire declaration.
  • Container diversion to a different port - the goods were supposed to leave through one port, but the shipping line redirected the container to another. The customs office of exit code in the declaration does not match the actual port of exit.
  • Missing export registration in the port system - even when the export declaration is correct, the goods must be registered as an export in the port system of the port of exit. If the exporter or freight forwarder fails to complete this registration, the customs office at the port does not see the declaration and does not confirm the export.

How We Help Close the MRN After Procedure 42

Exporting goods that previously went through Procedure 42 requires coordination between the customs systems of two countries. We help at every stage:

  • Diagnosing the cause of an open MRN - we determine why the export declaration was not closed. We check whether the problem lies with the customs office of exit code, inter-system communication, or missing registration in the port system.
  • Cross-country coordination - we have experience handling cases that require communication between the Polish customs system and systems in Germany, the Netherlands, and Belgium. We know how procedures work in each of these countries.
  • Export registration in the correct port system - if the goods were not properly registered at the port of exit, we carry out retroactive registration based on transport documents.
  • Obtaining the export confirmation - we bring the process to MRN closure and issuance of the export confirmation, which is essential for applying the 0% VAT rate. Submit your order.

Frequently Asked Questions

Does Procedure 42 affect MRN closure?

Procedure 42 itself relates to import, not export. However, when goods from Procedure 42 are subsequently exported outside the EU, complications with MRN closure may arise - especially when the export declaration is filed in a different country than the port of actual exit of the goods from the EU.

In which country should the export declaration be filed after Procedure 42?

As a general rule, the export declaration is filed in the country where the goods are packed or loaded for export transport. If goods from Procedure 42 were delivered to another EU country and are being exported from there, the declaration is usually filed in that second country. The exact rules are governed by the Union Customs Code (Regulation 952/2013).

My MRN is open after exporting goods from Procedure 42 - what should I do?

First, verify whether the export declaration contains the correct customs office of exit code corresponding to the port through which the goods actually left the EU. A common cause of an open MRN in this scenario is incorrect routing of the declaration between the customs systems of two countries. Let us diagnose the issue - we will quickly identify the cause.

Does Procedure 42 complicate obtaining the export confirmation?

Procedure 42 itself does not complicate obtaining the export confirmation - it is a standard import procedure. Complications arise when, during the subsequent export, the export declaration is filed in one EU country while the goods physically leave the EU through a port in another country. This requires proper communication between the customs systems of both countries.
