Registration of sugar export contracts remains subject to existing conditions; mills must notify the authority by email after supply. Exporters must obtain Registration Certificates under the existing policy framework; the conditions and modalities in Policy Circular No. 62, as modified by Policy Circular No. 63, remain operative. Sugar mills supplying sugar to registered contract holders must intimate the designated authority by email immediately after each supply to an RC holder, and this email-notification obligation is mandatory for compliance with export registration procedures.
