Source material governs scrap exemption; approved classification list shields earlier period, while penalty was deleted.

Ferrous waste and scrap generated from CRCA sheets used to manufacture metal containers did not qualify for exemption under Notification No. 171/88 because the relevant condition was tied to the source material, not the finished containers; the exemption was therefore unavailable. Duty could not be recovered for the period covered by the approved classification list, but it became payable once that approval no longer governed the assessment. Penalty was set aside because the dispute concerned interpretation of the exemption notification and the surrounding circumstances did not justify penal action.

Issues: (i) Whether ferrous waste and scrap generated in the manufacture of metal containers from CRCA sheets was eligible for exemption under Notification No. 171/88. (ii) Whether duty could be demanded for the period during which the classification list granting the exemption had been approved. (iii) Whether penalty was justified.

Issue (i): Whether ferrous waste and scrap generated in the manufacture of metal containers from CRCA sheets was eligible for exemption under Notification No. 171/88.

Analysis: The notification exempted ferrous waste and scrap only when it arose from the specified class of goods and the conditions attached to the exemption were satisfied. The relevant expression "goods" was held to refer to the raw material from which the waste and scrap arose, not the finished containers. Since the waste and scrap emerged from CRCA sheets and not from the finished drums and barrels, the condition for exemption was not fulfilled.

Conclusion: The exemption under Notification No. 171/88 was not available to the waste and scrap in question.

Issue (ii): Whether duty could be demanded for the period during which the classification list granting the exemption had been approved.

Analysis: For the period when the classification list allowing the benefit of the notification remained approved, the demand could not be sustained. The approved classification list protected the assessee for that interval, while liability could arise only for the later period after the approval ceased to govern the assessment.

Conclusion: Duty was not recoverable for July 1990 to November 1990, but was payable for December 1990 to February 1992.

Issue (iii): Whether penalty was justified.

Analysis: The dispute turned on interpretation of the exemption notification and the entry therein. In view of the nature of the controversy and the surrounding circumstances, penal action was not considered appropriate.

Conclusion: The penalty was set aside.

Final Conclusion: The appeal succeeded only in part: the exemption claim failed on merits, the earlier period was protected by the approved classification list, and the penalty was deleted.

Ratio Decidendi: For exemption from duty on waste and scrap arising under a notification, the governing condition is the character of the source material from which the scrap arises, and not the identity of the finished product manufactured from that material.
