Zinc dross classification and limitation turn on prior Tribunal ruling, approved classification list, and absence of suppression.

Zinc dross was treated as classifiable under Heading 7901.20, and the earlier Tribunal view rejecting classification under Chapter 26 was followed, so the Chapter 26 claim failed. On limitation, a classification list had been approved, the relevant facts were already within the Revenue's knowledge, and no suppression was shown; accordingly, the extended period was unavailable. The demand for the disputed period was therefore time-barred, and the personal penalty could not survive and was set aside.

Issues: (i) Whether zinc dross was classifiable under Chapter 79 rather than Chapter 26; (ii) Whether the demand was barred by limitation and, if so, whether personal penalty could survive.

Issue (i): Whether zinc dross was classifiable under Chapter 79 rather than Chapter 26.

Analysis: The classification dispute had already been decided against the assessee by an earlier Tribunal decision holding zinc dross to be classifiable under Heading 7901.20 and rejecting classification under Heading 26.20.

Conclusion: The classification contention was rejected and the assessee's claim under Chapter 26 did not succeed.

Issue (ii): Whether the demand was barred by limitation and, if so, whether personal penalty could survive.

Analysis: The assessee had filed a classification list effective from 1-3-1988 which was approved by the proper officer. The demand covered a period from 1-3-1988 to 31-7-1989, while the show cause notice was issued only in July 1992. The record did not establish any suppression of material facts by the assessee, and the fact that the assessments were provisional and later finalized showed that the relevant information was within the knowledge of the Revenue. In these circumstances, the extended period was not available.

Conclusion: The demand was held to be time-barred and the personal penalty was also set aside.

Final Conclusion: The appeal succeeded on limitation, resulting in deletion of the demand and penalty, although the classification issue was decided against the assessee.
