In all other cases, the exportation of scheduled substances listed in Category 2 may be authorized at the request of the operators concerned on a global basis by the issue of an open individual authorization.

In such cases, the holder shall enter the details of this authorization in the relevant customs export declaration. In accordance with the provisions laid down by the competent authorities, the holder of such an authorization shall furnish information in a summary form about exports made under the authority of the authorization. The open individual authorization may be suspended or revoked whenever there are reasonable grounds for belief that its holder is not longer a fit and proper person to hold an authorization, or that the conditions under which the authorization was issued are no longer valid.
