Article 5

The tariff preferences provided for by this Regulation shall apply to imports of products included in the arrangements enjoyed by the beneficiary country in which they originate.

The rules concerning the definition of the concept of originating products, the proof of origin and the methods of administrative cooperation, for the purposes of the arrangements referred to in Article 1(2) of this Regulation, are laid down in Commission Regulation (EEC) No 2454/93.

Regional cumulation within the meaning of Commission Regulation (EEC) No 2454/93 shall also apply where a product used in further manufacture in a country belonging to a regional group originates in another country of the group, which does not benefit from the arrangements applying to the final product, provided that both countries benefit from regional cumulation for that group.
