Pusher type furnace capacity and show-cause notice limits upheld in duty assessment, with later periods left for separate adjudication.

Technical inspection supported classification of the furnace as a pusher type furnace, and the annual production capacity under the Hot Re-rolling Mills Annual Capacity Determination Rules, 1997 was upheld at 2536 MT for 1997-98. The determination rested on expert findings noting back-end charging, a pushing mechanism, rails and a V-shaped hearth structure, and movement of material from the back end to the discharge side. Duty liability could not be extended beyond the period covered by the show cause notice, so the demand was confined to the noticed period and later periods were left for separate adjudication through pending notices.

Issues: (i) Whether the furnace installed in the appellant's premises was a pusher type furnace and whether the annual capacity of production was correctly determined at 2536 MT for the year 1997-98; (ii) Whether the duty demand could be confined to the period covered by the show cause notice and whether subsequent periods were required to be dealt with separately.

Issue (i): Whether the furnace installed in the appellant's premises was a pusher type furnace and whether the annual capacity of production was correctly determined at 2536 MT for the year 1997-98.

Analysis: The capacity determination turned on the nature of the furnace and the applicable utilised hours under the Hot Re-rolling Mills Annual Capacity Determination Rules, 1997. The furnace was inspected by technical experts, whose report recorded features consistent with a pusher type furnace, including back-end charging, pushing mechanism, rails/V-shaped hearth structure, and movement of raw material from the back end to the discharge side. The finding was based on expert opinion and was accepted.

Conclusion: The classification of the furnace as a pusher type furnace and the annual capacity determination at 2536 MT for 1997-98 were upheld, against the assessee.

Issue (ii): Whether the duty demand could be confined to the period covered by the show cause notice and whether subsequent periods were required to be dealt with separately.

Analysis: The demand sustained in the impugned order extended beyond the period specifically covered by the show cause notice. The notice had confined the proposed demand to the period 1-9-1997 to March 1998, and the assessee had been put on notice only in respect of that period. Any liability for later periods required separate consideration through pending notices.

Conclusion: The demand was confined to the period covered by the show cause notice, and the direction to pay duty for subsequent periods was set aside with a direction for separate adjudication of pending show cause notices.

Final Conclusion: The appeal succeeded only to the extent of limiting the duty liability to the noticed period, while the furnace classification and capacity determination were maintained.

Ratio Decidendi: A duty demand cannot be extended beyond the scope of the show cause notice, and capacity determination based on technical expert inspection will be sustained where the evidence supports the furnace classification adopted by the authority.
