Duty free import authorisation conditions revised: bonds, use-certificates and duty consequences govern post-clearance compliance. Amendments to conditions for imports under a Duty Free Import Authorisation require a bond with surety or security where imports occur before export obligations are discharged, obliging payment of duty with interest if conditions are not met. For imports after discharge, availing rebate or CENVAT credit requires a bond to use materials in manufacture and a six-month certificate of use; transfers or transferred authorisations may require payment of additional duty with interest unless duty is paid at clearance, in which case CENVAT credit may be claimed. Proof of not availing rebate or CENVAT may permit clearance without the bond.
