Refund limitation and Section XVI classification: new appellate classification claims cannot bypass time limits, and section notes control tariff treatment.

A refund claim cannot be expanded before the appellate authority by introducing a new classification basis after the statutory limitation period has expired, and the ancillary claim under Chapter 98 also failed for want of project import registration. Epoxy bars imported for generator use were not classifiable as parts of a generating set merely because they were suitable for that purpose; classification under Section XVI had to follow the order of the section notes, with Note 2(b) applying only after Note 2(a) was excluded. The customs classification and related refund-based reliefs therefore failed.

Issues: (i) whether a new classification claim raised before the appellate authority, resulting in enhanced refund relief, was barred by limitation; (ii) whether epoxy bars imported for generator use were classifiable as parts of a generating set under Section XVI rather than under the heading adopted by customs.

Issue (i): Whether a new classification claim raised before the appellate authority, resulting in enhanced refund relief, was barred by limitation.

Analysis: The refund applications had been filed on one basis, but a different classification was pursued before the appellate authority. The limitation prescribed for refund claims applied to the claim as finally presented, and a fresh ground introducing a new classification after expiry of the statutory period could not escape the time limit. The earlier assessment and the subsequent attempt to change the basis of refund did not permit reopening the claim beyond the prescribed period. The absence of project import registration also supported rejection of the ancillary claim under Chapter 98.

Conclusion: The new classification-based refund claim was time-barred and the finding against the assessee was .

Issue (ii): Whether epoxy bars imported for generator use were classifiable as parts of a generating set under Section XVI rather than under the heading adopted by customs.

Analysis: Chapter Note 2(a) to Section XVI governed parts which were themselves goods of Chapter 85, and Note 2(b) applied only to other parts after Note 2(a) was excluded. The imported goods could not be taken directly to the claimed heading merely because they were suitable for use with a generator. The note structure and the more specific tariff treatment favoured the customs classification rather than the assessee's claimed heading.

Conclusion: The goods were not classifiable under the claimed generator-related heading and the assessee's classification plea failed.

Final Conclusion: The challenge to the customs classification and the related refund-based reliefs failed in both sets of appeals, and the orders below were left undisturbed.

Ratio Decidendi: A refund claim cannot be enlarged before the appellate authority by introducing a new classification after expiry of the statutory limitation period, and tariff classification under Section XVI must follow the order of the section notes, with Note 2(b) operating only after Note 2(a) is inapplicable.
