Missing IE599 - What to Do When You Don't Have Proof of Export?

Updated: March 2026Reading time: ~8 min

Your goods have reached the buyer, but the export confirmation never arrived? This is one of the most common problems in indirect export -- when the export declaration was filed in one EU member state but the goods left the EU through a port in another. A missing export confirmation does not mean the goods stayed in the EU. It usually means something went wrong or was delayed in the chain of customs messages.

Note on naming: IE599 is the historical name for the export confirmation under the older ECS system. Today the same message is called CC599C in Poland (AES PLUS, since 31 October 2024) and Ausgangsvermerk in Germany (ATLAS). Other EU member states use their own local names. Throughout this guide, “export confirmation” refers to the current message regardless of country.

Why Is the Export Confirmation Essential?

The export confirmation message is the official proof of export generated by the AES system once the export procedure is closed. It matters for two reasons:

  1. Customs confirmation -- it proves the goods have left the EU customs territory, closing the export operation in the customs system.
  2. Tax confirmation -- it is the primary document entitling the exporter to apply the 0% VAT rate on export supplies (Art. 146(1)(a) of the EU VAT Directive; Art. 41(6) of the Polish VAT Act).

Without the export confirmation (or another admissible document -- more on that below), the exporter must charge the domestic VAT rate (23% in Poland) on the export supply.

Who Is Responsible for Closing the MRN and Generating the Export Confirmation?

MRN closure happens automatically -- no application from the exporter is required. Responsibility is distributed across several parties:

  • Carrier / port terminal -- responsible for submitting IE507 (presentation of goods) and IE590 (exit notification) to the customs office of exit.
  • Customs office of exit (e.g., Rotterdam, Hamburg) -- processes IE507/IE590 and sends IE518 to the customs office of export.
  • Customs office of export (e.g., in Poland) -- based on IE518, generates the export confirmation (CC599C in Poland) and delivers it to the declarant.

Most commonly, the problem lies at the first link -- the carrier or terminal did not submit IE590, so the entire chain never started.

Step by Step -- What to Do When the Export Confirmation Is Missing

Step 1: Check MRN Status (days 1-7 after loading)

Before taking action, make sure enough time has passed. The typical time from loading to export confirmation is 2-5 business days. Check the status:

Step 2: Contact the Forwarder (days 7-14)

If the export confirmation has not arrived after 7-10 business days, contact the forwarder or customs agent at the port of exit. Ask:

  • Was the container loaded onto the planned vessel?
  • Were IE507 and IE590 submitted to the customs system?
  • Did the export pre-notification (e.g., in Portbase) contain the correct MRN?

Step 3: Gather Proof of Exit (days 14-30)

Prepare documents confirming the physical export:

  • Bill of Lading (B/L) or other transport document (CMR, AWB)
  • Delivery confirmation from the buyer in the third country
  • Carrier Track & Trace with delivery confirmation
  • Vessel manifest with container number
  • Third-country customs documents (e.g., import SAD)

Step 4: File an Enquiry Procedure

If the export confirmation still has not arrived, initiate the enquiry procedure at the customs office of export under Article 335 of Commission Implementing Regulation (EU) 2015/2447. Under Art. 335(1) IA, the customs office of export may, on its own initiative, request information from the declarant where, after 90 days from the release of goods (IE529), it has not been informed of the exit of the goods. The declarant may, however, file a request with the customs office at any time after release under Art. 335(2) and (3) IA.

The application should include:

  • MRN
  • Date and place of loading
  • Identification of the customs office of exit (port)
  • Collected proof of exit

Step 5: Await the Customs Decision (2-8 weeks)

The customs office of export verifies the evidence, contacts the customs office of exit, and makes a decision:

  • MRN closure -- the export confirmation is generated
  • Further investigation -- additional evidence required
  • Invalidation of declaration -- if the goods did not leave the EU (Art. 248(2) UCC-DA 2015/2446)

Key Deadlines to Remember

  • 90 days from IE529 -- threshold after which the customs office of export may initiate an enquiry procedure ex officio (Art. 335(1) IA 2015/2447). The declarant may file a request with the customs office at any time after release (Art. 335(2)-(3) IA).
  • 150 days from IE529 -- deadline for invalidation of the declaration if goods did not exit (Art. 248(2) DA 2015/2446)
  • VAT return deadline -- the export confirmation must be obtained before the deadline for the return covering the delivery period or the following period (Art. 41(6)-(7) Polish VAT Act)
  • 5 years -- statute of limitations for VAT corrections (Art. 70 Polish Tax Ordinance)

What If the VAT 0% Deadline Has Passed?

If the export confirmation was not received before the deadline for the return covering the delivery period NOR the following period:

  1. You must apply the domestic 23% VAT rate in the return for the delivery period (Art. 41(8) Polish VAT Act).
  2. After subsequently obtaining the export confirmation, you can file a VAT correction and recover the overpaid VAT (Art. 41(9) Polish VAT Act).
  3. The correction is available for up to 5 years from the end of the year in which the tax payment was due (Art. 70 Polish Tax Ordinance).

A missing export confirmation before the VAT return deadline means you must apply the domestic rate (Art. 41(9) Polish VAT Act). Act early.

Frequently Asked Questions (FAQ)

Why is IE599 missing even though goods have left the EU?

IE599 is generated by the AES system only when the customs office of exit (the border office) confirms the export. If the goods physically left but the office did not close the MRN, the confirmation is missing. Common causes: ECS technical error, port system delay, or missing data from the carrier.

What documents can replace IE599?

Under Art. 335 of Commission Implementing Regulation (EU) 2015/2447 and Art. 41(6a) of the Polish VAT Act, when obtaining IE599 is impossible, customs authorities may accept alternative proof of export: signed CMR, bill of lading, export invoice, or carrier's declaration. The decision rests with the competent customs authority.

What happens if I don't have IE599 before the VAT return deadline?

Under Art. 41(9) of the Polish VAT Act, if you don't have proof of export before the return deadline, you cannot apply the 0% rate -- you must declare the domestic rate. After obtaining IE599, you can file a correction. Consult a tax advisor for your specific situation.
