Revalidation of export authorizations allows cotton exporters to obtain a one-time extension or penalty-free surrender. Holders of Registration Certificates (RC) for cotton exports to Pakistan may obtain a one-time extension of RC validity for up to thirty days or surrender un-utilized or partially utilized RCs without penalty, provided the request for revalidation or surrender is made to the concerned Regional Authority within the RC validity period; Regional Authorities must report weekly to Headquarters the numbers and quantities of RCs revalidated and surrendered.
