Customs exemption claims may be examined even without a separate challenge to the original assessment, if the lower entry is otherwise admissible.

Where an importer has claimed exemption under a customs notification, the proper officer must examine whether the correct concessional entry applies and extend it if admissible. In this customs note, the claimed lower exemption rate for imported flax fibre was not rejected merely because the original assessment had not been separately challenged. The matter was therefore required to be re-examined by the original authority, with the assessment to be modified if the lower entry was found applicable, and refund of differential duty could then be pursued.

Issues: Whether the importer could seek the benefit of a lower exemption entry under Notification No. 21/2002-Customs dated 01.03.2002 by refund claim when the original assessment had not been separately challenged.

Analysis: The appeal concerned imported flax fibre on which duty had been paid at a concessional rate under one serial number of the notification, while the importers later claimed a lower rate available under another serial number. The assessment had not been revised before the refund claim was rejected. The Tribunal held that once the exemption benefit was claimed, the assessing or proper officer was required to examine the claim and extend the correct exemption if admissible. The absence of a challenge to the assessment order did not prevent consideration of the claim in the facts of the case, and the matter warranted fresh examination by the original authority.

Conclusion: The matter was remitted to the original authority to examine the claim for exemption under the relevant serial number of the notification and to modify the assessment accordingly, with liberty to claim refund of the differential duty thereafter.

Ratio Decidendi: Where an exemption benefit is otherwise legally available and has been claimed, the proper officer must examine and apply the correct exemption, and the claim cannot be rejected merely because the original assessment was not separately challenged.
