Where Community goods are stored on the premises of a customs warehouse or the storage facilities used for goods under the warehousing arrangements, specific methods of identifying such goods may be laid down with a view, in particular, to distinguishing them from goods entered for the customs warehousing arrangements.

The customs authorities may permit common storage where it is impossible to identify at all times the customs status of each type of goods. Prefinanced goods shall be excluded from such permission.

Goods in common storage shall share the same eight-digit CN-code, the same commercial quality and the same technical characteristics.

For the purpose of being declared for a customs-approved treatment or use the goods in common storage, as well as, in particular circumstances, identifiable goods which fulfill the conditions of the second subparagraph of paragraph 2, may be deemed to be either Community goods or non-Community goods.

Application of the first subparagraph shall, however, not result in a given customs status being assigned to a quantity of goods greater than the quantity actually having that status which is stored at the customs warehouse or the storage facilities when the goods declared for a customs-approved treatment or use are removed.
