Extended limitation and vitamin-mixture classification: deliberate suppression is required, and binding precedent governs synthetic preparations.

Extended limitation under the proviso to Section 11A(1) requires proof of deliberate suppression, false declaration, or intent to evade duty; where classification lists were filed and approved after departmental enquiry, with queries, replies, and sample testing on record, mere non-disclosure of ingredient proportions was insufficient to invoke the extended period. On classification, synthetic preparations containing mixtures of vitamins were treated as falling outside Chapter 23.02 and as classifiable under Chapter 29.36 in line with binding precedent, rather than as animal feed supplements merely because they are used for nutrition. The demand and penalty were therefore unsustainable on both limitation and classification.

Issues: (i) Whether the demand was barred by limitation and the extended period under the proviso to Section 11A(1) could be invoked. (ii) Whether the products were classifiable under Chapter 23.02 as animal feed supplements or under Chapter 29.36 as intermixtures of vitamins.

Issue (i): Whether the demand was barred by limitation and the extended period under the proviso to Section 11A(1) could be invoked.

Analysis: The classification lists had been filed and approved after departmental enquiry. The record showed repeated departmental queries, replies, and sample testing, and there was no reliable material to show deliberate withholding of ingredients, false declaration, or suppression with intent to evade duty. Mere non-disclosure of proportions, when the proper officer could have sought them during approval, was insufficient to attract the extended period.

Conclusion: The proviso to Section 11A(1) was not invocable, and the demand was time-barred; this issue is in favour of the assessee.

Issue (ii): Whether the products were classifiable under Chapter 23.02 as animal feed supplements or under Chapter 29.36 as intermixtures of vitamins.

Analysis: On merits, the products were found to be similar to goods already considered by the Larger Bench, which held that synthetic preparations containing mixtures of vitamins fall outside Chapter 23 and are classifiable under Chapter 29.36. The Tribunal followed that binding view and rejected the contrary classification adopted in the impugned order.

Conclusion: The products were not classifiable under Chapter 23.02 and the classification under Chapter 29.36 could not be sustained against the assessee; this issue is also in favour of the assessee.

Final Conclusion: The demand and penalty were unsustainable both on limitation and on classification, so the impugned order was set aside and the appeal succeeded.

Ratio Decidendi: The extended period of limitation under Section 11A can be invoked only on proof of deliberate suppression or misstatement with intent to evade duty, and synthetic vitamin preparations are classifiable according to their essential character and binding precedent rather than as animal feed supplements merely because they are used for nutrition.
