Approved classification list can be reopened for differential duty, with duty recomputed after allowing admissible Modvat credit

An approved classification list does not create an estoppel against law, and the Department may reopen classification under Section 11A of the Central Excises and Salt Act, 1944 to recover duty where the earlier classification is found incorrect. The revised classification may also support a demand for the relevant past period, rather than operating only prospectively from the date of notice or trade notice. On recomputation, the duty must be worked out after allowing admissible Modvat credit on inputs used in manufacture. The classification under sub-heading 3923.90 and the differential duty liability were upheld, while quantification was remanded for fresh calculation with Modvat benefit.

Issues: (i) Whether the Department could reopen an approved classification list and demand duty under Section 11A of the Central Excises and Salt Act, 1944. (ii) Whether the demand could be sustained retrospectively from the relevant period notwithstanding the approved classification and the Board's instructions under Section 37B of the Central Excises and Salt Act, 1944. (iii) Whether, on recomputation of duty, Modvat credit on inputs had to be taken into account.

Issue (i): Whether the Department could reopen an approved classification list and demand duty under Section 11A of the Central Excises and Salt Act, 1944.

Analysis: The approved classification list did not create an estoppel against law. Section 11A was treated as enabling the Department to reopen classification and recover duty where the earlier classification was found to be incorrect. The reasoning relied on the settled position that assessment can be revisited even after approval of the classification list.

Conclusion: Yes. The Department could reopen the approved classification list and proceed under Section 11A.

Issue (ii): Whether the demand could be sustained retrospectively from the relevant period notwithstanding the approved classification and the Board's instructions under Section 37B of the Central Excises and Salt Act, 1944.

Analysis: The Board's instruction classifying the goods under a different heading justified the revised view for the relevant period. The show cause notice was read as seeking review of the approved classification with effect from the earlier date mentioned in it, and the contention that the demand could operate only prospectively from the date of the notice or trade notice was rejected.

Conclusion: Yes. The differential duty demand for the relevant past period was sustainable.

Issue (iii): Whether, on recomputation of duty, Modvat credit on inputs had to be taken into account.

Analysis: The assessee had pressed for Modvat benefit if the goods were classified under Chapter 39, and the record showed that the point had been raised during the proceedings. In the interest of justice, the duty payable was required to be worked out after considering admissible Modvat credit on inputs used in manufacture.

Conclusion: Yes. The duty had to be recomputed after allowing admissible Modvat credit.

Final Conclusion: The classification under sub-heading 3923.90 and the liability to differential duty were upheld, but the quantification of duty was sent back for fresh working after giving credit for admissible Modvat benefit.

Ratio Decidendi: An approved classification list does not bar the Department from reopening classification and recovering duty under Section 11A, and while doing so the duty must be quantified after allowing legally admissible Modvat credit.
