Extended limitation and tariff classification depend on proved suppression and chapter notes governing the goods' composition.

Approved classification lists and final RT-12 assessments weighed against invoking the extended limitation period on allegations of suppression and misdeclaration; without provisional assessment or proved intent to evade duty, mere non-filing of a separate classification list was insufficient, so limitation was not extended. On classification, the goods were treated as alloys other than ferro-alloys with iron content below the relevant threshold, and applying Note 3 to Section XV with Note 1(c) to Chapter 72, they were held outside Chapter 72 and classifiable under Chapter 81. The Revenue challenge therefore failed on both limitation and tariff classification, and the order dropping proceedings was sustained.

Issues: (i) Whether the extended period of limitation under the excise law could be invoked on the allegation of suppression and misdeclaration; (ii) Whether the goods were correctly classifiable under Chapter 81 rather than Chapter 72 on the basis of their composition and tariff notes.

Issue (i): Whether the extended period of limitation under the excise law could be invoked on the allegation of suppression and misdeclaration.

Analysis: The classification list had been approved by the department and the RT-12 assessments had also attained finality. The record did not show any provisional assessment, and the approval process required the department to examine the goods and, if necessary, obtain chemical testing before granting approval. In these circumstances, the absence of a separate classification list for the disputed goods did not by itself establish suppression with intent to evade duty.

Conclusion: The extended period was not invokable and the finding against limitation was in favour of the assessee.

Issue (ii): Whether the goods were correctly classifiable under Chapter 81 rather than Chapter 72 on the basis of their composition and tariff notes.

Analysis: On the facts recorded, the goods were found to be alloys other than ferro-alloys, with iron content below the threshold noted in the order. Applying Note 3 to Section XV and Note 1(c) to Chapter 72, the goods were held not to fall under Chapter 72 and to be classifiable under Chapter 81.

Conclusion: The classification under Chapter 81 was sustained and this issue was decided in favour of the assessee.

Final Conclusion: The Revenue challenge failed both on limitation and on the substantive classification dispute, and the order dropping the proceedings was sustained.

Ratio Decidendi: Where the department has approved the classification list and completed assessment without provisionality, the extended period cannot be invoked absent proved suppression, and tariff classification must follow the governing chapter notes and composition of the goods.
