Substantive compliance prevails where delayed end-use certificate filing does not defeat concessional customs duty benefit

A customs exemption or concessional duty benefit should not be denied merely because an end-use certificate was filed after the stipulated period, where the notification itself permits extension of time and the substantive condition has been met. The notification's time requirement is not rigidly confined when the Assistant Commissioner may allow further time, and a formal request for extension is not treated as decisive if compliance is otherwise established. The operative principle is that substantive fulfilment prevails over a purely technical objection to delayed production of the certificate, so long as the underlying condition is not in dispute.

Issues: Whether benefit of concessional customs duty under Notification No. 21/2002-Cus. could be denied merely because the end-use certificate was produced after the stipulated period, despite the substantive condition having been fulfilled.

Analysis: The notification required production of the end-use certificate within six months or such extended period as the Assistant Commissioner may allow. The period was thus not rigidly confined, and the discretion to extend was available. Since the substantive requirement of producing the end-use certificate was not disputed and had been fulfilled, denial of the notification benefit solely on the ground that no formal extension had been sought was treated as an unwarranted technical objection.

Conclusion: The benefit of the notification could not be denied on the alleged delay in producing the end-use certificate, and the issue was decided in favour of the assessee.

Final Conclusion: The Revenue's challenge failed because substantive compliance with the notification condition prevailed over the procedural objection regarding the timing of the certificate.

Ratio Decidendi: Where a notification permits extension of time for fulfilment of a condition and the substantive requirement is ultimately satisfied, exemption or concessional benefit should not be denied merely for want of a formal request for extension.
