Article 4 Proof of origin

As part of completion of formalities in connection with the import of products which are subject to intra-Community surveillance measures or protective measures, the relevant authorities of the importing Member State may ask the importer to state the origin of the products on the customs declaration or on the application for an import document.

Additional proof may be requested only at customs clearance and in cases where serious and well-founded doubts make such proof essential in order to establish the true origin of the products in question. However, a request for such additional proof may not in itself prevent the import of the goods.
