Finality of assessable value bars indirect reopening through refund claim when valuation was already settled.

Assessable value fixed under Rule 8 by adding 110%/115% of cost of production had already attained finality in the assessee's own prior proceedings. Because that valuation and the resulting duty basis were conclusively settled, the same issue could not be reopened indirectly through a refund claim. The Tribunal treated the refund foundation as non-existent once the valuation issue stood finalized and therefore found it unnecessary to examine the remaining objections. The refund claim was held not maintainable on the settled valuation issue.

Issues: Whether a refund claim could be entertained on the ground that 10%/15% of the cost of production was not required to be added to arrive at the assessable value, when the valuation had already been conclusively settled in the assessee's own case.

Analysis: The assessable value had earlier been determined under Rule 8 of the Central Excise Valuation Rules by adding 110%/115% of the cost of production. That valuation was upheld in the assessee's own case in prior appellate proceedings, where the assessee had not contested the valuation and the dispute survived only on penalty. Once the valuation and duty basis attained finality through a quasi-judicial process, the same issue could not be reopened indirectly through a refund claim. The foundation of the refund claim therefore ceased to survive, and the Tribunal found it unnecessary to examine the remaining objections.

Conclusion: The refund claim was not maintainable on the same settled valuation issue, and the appeal failed.
