Corrugation as manufacture and cum-duty valuation govern Modvat credit, with credit and penalty issues remanded.

Corrugation of plain galvanised mild steel sheets was treated as manufacture, and the corrugated sheets were held classifiable under the tariff heading relied on by the department. On Modvat credit, duty-paid inputs used in the final product could not be denied merely for procedural non-compliance once duty liability arose from the department's view. Assessable value also had to be reconsidered on a cum-duty basis by deducting the duty element, with penalty to be re-examined in light of the final duty liability. The matter was remanded for fresh adjudication on credit, valuation, and penalty.

Issues: (i) whether corrugation of plain galvanised mild steel sheets amounts to manufacture and whether the corrugated sheets are classifiable under the tariff heading invoked by the department; (ii) whether the assessee is entitled to Modvat credit on duty-paid inputs and whether the assessable value should be worked out on a cum-duty basis, with consequential reconsideration of penalty.

Issue (i): whether corrugation of plain galvanised mild steel sheets amounts to manufacture and whether the corrugated sheets are classifiable under the tariff heading invoked by the department.

Analysis: The process of corrugation was treated as manufacture for purposes of duty. On classification, the note to Chapter 72 was read as covering flat rolled products that are corrugated, and the goods were held not to be outside the tariff merely because they were not products derived directly from rolling in the sense suggested by the appellant. The classification under the corrugated product heading was therefore considered appropriate.

Conclusion: The department's view on manufacture and classification was upheld against the appellant.

Issue (ii): whether the assessee is entitled to Modvat credit on duty-paid inputs and whether the assessable value should be worked out on a cum-duty basis, with consequential reconsideration of penalty.

Analysis: Once manufacture was accepted, credit on duty paid inputs used in the final product could not be denied merely for want of procedural compliance where duty liability had arisen from departmental interpretation. The assessable value also had to be reconsidered on a cum-duty basis after deducting the duty element. As these matters required verification of materials and evidence to be produced, the dispute was sent back for fresh determination, and penalty was left to be determined in light of the final duty liability.

Conclusion: The assessee's claim for reconsideration of Modvat credit and cum-duty valuation was accepted and the matter was remanded for fresh adjudication.

Final Conclusion: The order resulted in partial relief to the assessee, with the disputed duty, credit, valuation, and penalty questions required to be reconsidered by the adjudicating authority.

Ratio Decidendi: Where corrugation constitutes manufacture, Modvat credit on duty-paid inputs cannot be denied solely for procedural lapses, and assessable value must be determined on a cum-duty basis when duty is found payable.
