Export exemption for processed prawns and rejection of unaccounted wastage additions based on inherent processing loss.

Cleaned, frozen and packed prawns exported by the assessee were treated as eligible for exemption under Section 5(3) of the Central Sales Tax Act read with the proviso to Section 9 of the Tamil Nadu General Sales Tax Act because the same issue had already been accepted in the assessee's earlier matter and that binding determination governed the present revision. Additions for alleged unaccounted loss or wastage during cleaning, freezing and packing were deleted because the Tribunal found the loss to be marginal, inherent in processing the commodity for export, and neither excessive nor unreasonable.

Issues: (i) whether cleaned, frozen and packed prawns exported by the assessee were entitled to exemption under Section 5(3) of the Central Sales Tax Act, 1956 read with the proviso to Section 9 of the Tamil Nadu General Sales Tax Act, 1959; and (ii) whether the additions made on account of alleged unaccounted loss or wastage in the course of cleaning, freezing and packing prawns were sustainable.

Issue (i): whether cleaned, frozen and packed prawns exported by the assessee were entitled to exemption under Section 5(3) of the Central Sales Tax Act, 1956 read with the proviso to Section 9 of the Tamil Nadu General Sales Tax Act, 1959.

Analysis: The exemption had already been accepted in the assessee's own earlier matter for the same question, and the Revenue had not pursued any timely enhancement challenge before the Tribunal. The present revision was governed by the earlier binding decision on the same assessee and same issue, which supported the grant of exemption on export sales of the processed prawns.

Conclusion: The exemption claim was upheld in favour of the assessee.

Issue (ii): whether the additions made on account of alleged unaccounted loss or wastage in the course of cleaning, freezing and packing prawns were sustainable.

Analysis: The Tribunal found that some loss was naturally bound to occur during cleaning, cutting, freezing and packing of prawns for export. The quantities involved were marginal in relation to the total purchases and turnover, and the claimed wastage was neither excessive nor unreasonable. On those facts, the additions treating the loss as unaccounted were not justified.

Conclusion: The additions were rightly deleted and the finding was in favour of the assessee.

Final Conclusion: The Revenue's revision petitions lacked merit because both the exemption claim and the deletion of the disputed additions were sustained.

Ratio Decidendi: Where processed export goods are covered by an earlier binding determination on exemption, and the claimed wastage is only marginal and inherent in the processing and packing of the commodity, the Revenue cannot sustain additions treating such loss as unaccounted.
