Drawback entitlement for re-exported imports requires identification, timeliness and Customs satisfaction for duty relief. Drawback under Section 74 allows re-exporting importers to claim refund of import duties subject to time limits, identification with original import documents, and exclusions for specified categories; periods may be extended on sufficient grounds and Customs satisfaction is required. Section 26A permits refund where goods are defective or non conforming if they have not been used except to discover defects and are exported, abandoned, destroyed or rendered commercially valueless in the presence of the Proper Officer within the prescribed period, which may be extended. Empty container import exemption requires durability, reusability, identifiability and procedural compliance.
