Customs exemption certificate produced later can still support refund where substantive notification conditions are met.

Where the substantive conditions of the customs exemption notifications were satisfied, later production of the required certificate with the refund claim was accepted as sufficient compliance, and the earlier non-production at clearance was treated as a procedural irregularity not defeating exemption. The Tribunal also noted that the refund claim was examined on the basis of the subsequently produced certificate rather than by reopening the assessment, and the finding on unjust enrichment supported grant of refund.

Issues: Whether the benefit of customs exemption notifications and consequential refund could be denied merely because the required certificate was produced after clearance of the imported goods.

Analysis: The exemption conditions were found to be satisfied on the facts, and the later production of the certificate along with the refund claim was treated as a sufficient and justifiable compliance. Non-production of the certificate at the time of clearance was treated as a procedural lapse and not as a substantive defect defeating the exemption. The Tribunal also noted that the assessment was not being reopened in the sense suggested by the Revenue, but the refund claim was being examined on the basis of the subsequently produced certificate establishing entitlement under the notifications. The finding on unjust enrichment also supported grant of refund.

Conclusion: The delayed production of the certificate was accepted, the exemption benefit was upheld, and the refund claim was allowed in favour of the assessee.

Ratio Decidendi: Where the substantive conditions of an exemption notification are met, subsequent production of a required certificate may be accepted, and prior non-production at clearance is only a procedural irregularity that does not by itself defeat refund or exemption.
