Open and complete the form "Application for authorisation to lodge simplified customs declarations pursuant to Article 166 of the Union Customs Code when exporting goods (0850)" on the Customs website. Download and complete the "Customs Authorisation Questionnaire Parts I to III" on the Customs website. (Note: AEO authorization holders do not need to send the questionnaire). Before processing, it is advisable to contact your contact person at the relevant main customs office to clarify any open questions regarding the form and, if applicable, the questionnaire. Print out the form and, if applicable, the questionnaire and send it to the relevant main customs office. If the main customs office has successfully checked whether all the requirements for approval have been met, you will receive the approval. If the requirements are not met, you will receive a notification that the application has been rejected. If your export goods are to be presented at packing or loading locations in other member states, you must also submit an application for "granting authorisation for centralised clearance in accordance with Article 179 of the Union Customs Code (UCC)". The application is made electronically via the EU Trader Portal (EU-TP) of the European Commission.
