Tariff reductions on the products listed in the Annexes to this Regulation shall be granted annually by means of Community tariff quotas open for the periods specified in the Annexes.

The following customs duties shall apply to the tariff quotas referred to in paragraph 1:

• for the products listed in Annexes I and II: the customs duties indicated in those Annexes,

• for the products listed in Annex III: the ad valorem duties indicated in that Annex, as well as, where applicable, the specific duties provided for in the Common Customs Tariff of the European Communities.

Entry under the tariff quotas specified in Annex II shall require presentation in support of the declaration of entry for free circulation of a certificate of authenticity in accordance with one of the specimens in Annex IIa, issued by the competent authorities of the country of origin as indicated in Annex IIb, stating that the products possess the specific characteristics indicated in Annex II.

However, in the case of concentrated orange juice, presentation of a certificate of authenticity may be replaced by presentation to the Commission before importation of a general attestation from the competent authority of the country of origin stating that concentrated orange juice produced therein contains no blood orange juice. The Commission shall then inform Member States so that they can advise their customs services. This information shall also be published in the C series of the Official Journal of the European Communities.
