Declaration of technical specifications required for duty free imports; RAs to verify, amend pre import, or require duty regularisation after import. Exporters must declare technical characteristics, quality and specifications for specified inputs in the DFIA application and shipping bills; RAs must record these details on the DFIA at issuance and verify identical details at EODC/redemption/transferability. If shipping bills lack details, the item must be deleted from the DFIA. Where shipping bill details differ, the DFIA can be amended only prior to import; if import already occurred with differing characteristics, the holder must regularise by paying duty with interest.
