The Member States shall provide that cereal seed

• which has been produced directly from basic seed or certified seed of the first generation officially certified either in one or more Member States or in a third country which has been granted equivalence under Article 16 (1) (b), or which has been produced directly from the crossing of basic seed officially certified in a Member State with basic seed officially certified in such a third country, and

• which has been harvested in another Member State,

shall, on request and without prejudice to the provisions of Directive 70/457/EEC, be officially certified as certified seed in any Member State if that seed has undergone field inspection satisfying the conditions laid down in Annex I for the relevant category and if official examination has shown that the conditions laid down in Annex II for the same category are satisfied.

Where in such cases the seed has been produced directly from officially certified seed of generations prior to basic seed, Member States may also authorize official certification as basic seed, if the conditions laid down for that category are satisfied.

Cereal seed which has been harvested in the Community, and which is intended for certification in accordance with paragraph 1, shall:

• be packed and labelled with an official label satisfying the conditions laid down in Annex V(A) and (B), in accordance with Article 9(1), and

• be accompanied by an official document satisfying the conditions laid down in Annex V(C).

The provisions in the first subparagraph on packing and labelling may be waived if the authorities responsible for field inspection, those drawing up the documents for the certification of seeds which have not been definitively certified and those responsible for certification are the same, or if they agree on exemption.
