1. In the case of prior exportation the authorisation shall specify the period within which the non-Community goods must be declared for the arrangements, taking account of the time required for procurement and transport to the Community.
2. The period referred to in paragraph 1 shall not exceed:
(a) three months for goods subject to a common market organisation;
(b) six months for all other goods.
The period of six months may, however, be extended where the holder submits a reasoned request, provided that the total period does not exceed twelve months. Where the circumstances so warrant the extension may be allowed even after the original period has expired.]
