CAS-4 valuation defect sustains differential duty, but penalty fails absent intent to evade duty.

CAS-4 is an accepted costing standard for excise valuation, and where the assessee's costing statement is materially defective, a differential duty demand based on the revised assessable value can be sustained. However, penalty under Rule 25 is not automatic merely because a different valuation basis is adopted; absent material showing intent to evade duty or other culpable conduct, penal consequences are not warranted. The duty demand was upheld, while the penalty was set aside.

Issues: (i) whether the differential duty demand based on CAS-4 valuation could be sustained, and (ii) whether penalty under Rule 25 of the Central Excise Rules, 2002 was imposable for alleged contravention of Rules 4, 6 and 8 of the Central Excise Rules, 2002.

Issue (i): whether the differential duty demand based on CAS-4 valuation could be sustained.

Analysis: The assessable value adopted by the appellant was compared with the CAS-4 costing statement furnished before the adjudicating authority. The statement was found to be materially defective, and the difference between the declared value and the accepted costing standard showed a differential assessable value. CAS-4 is an accepted costing standard for cost determination, and no material legal ground was shown to displace the valuation adopted on that basis.

Conclusion: The differential duty demand was sustained.

Issue (ii): whether penalty under Rule 25 of the Central Excise Rules, 2002 was imposable for alleged contravention of Rules 4, 6 and 8 of the Central Excise Rules, 2002.

Analysis: Valuation involved an intricate exercise, and adoption of a different costing standard did not by itself show an intention to evade duty. The appellant had voluntarily furnished CAS-4, and no questionable conduct warranting penal consequence was established.

Conclusion: The penalty was set aside.

Final Conclusion: The appeal succeeded only on the penalty aspect, while the duty demand remained intact.

Ratio Decidendi: Where the assessee's valuation basis is found defective but no intent to evade duty is established, differential duty may be sustained while penalty is not warranted.
