Article 4
1. Containers and the corresponding certificates shall be submitted for verification, together and at the earliest opportunity, to a Community authority either in the Member State where they are imported or in the Member State for which they are destined, as indicated in accompanying documents. 2. In cases where rough diamonds are imported into a Member State where there is no Community authority, they shall be submitted to the appropriate Community authority in the Member State for which they are destined. If a Community authority exists neither in the importing Member State nor in the Member State of destination they shall be submitted to an appropriate Community authority in another Member State. 3. The Member State where the rough diamonds are imported shall ensure their submission to the appropriate Community authority provided for in paragraphs 1 and 2. Customs transit may be granted to that effect. If such customs transit is granted, the verification provided for by this Article shall be suspended until arrival at the appropriate Community authority. 4. The importer shall be responsible for the proper movement of the rough diamonds and the costs thereof. 5. A Community authority shall opt for either of the following methods to verify that the content of a container matches the particulars on the corresponding certificate: (a) it will open each container with a view to such verification; or (b) it will identify the containers to be opened with a view to such verification on the basis of a risk analysis or equivalent system that gives due consideration to rough diamond shipments. 6. A Community authority shall complete the verification without delay.
