Revalidation of advance licences: expired licences may be revalidated for a limited additional period where exports were completed. Revalidation of advance licences issued under the 1992-97 policy is permitted for a further limited period where exports have been completed but licences expired before utilization; applicants must file with the Regional Licensing Authority within the specified short window and revalidation is not available for licences already made transferable or for licences affected by misrepresentation or fraud.
