Security for provisional Mega Power Project imports: fixed deposit covering customs duty must be furnished or forfeited. Where an importer claims exemption under a provisional Mega Power Project status certificate, the importer must furnish at importation a Fixed Deposit Receipt from a Scheduled Bank in the name of the President of India for a term of thirty six months or more, equal to the customs duty otherwise payable, to the Deputy Commissioner or Assistant Commissioner of Customs; failure to furnish the final status certificate within thirty six months permits appropriation of the security towards the customs duty.
