Pump exemption classification turns on whether component assemblies are parts or the exempt equipment itself, with fresh quantification required.
Bowl Assembly was treated as the power driven pump for exemption purposes, while Column Assembly and Discharge Head Assembly were treated as parts or accessories outside the scope of Notification No. 56/95. Earlier findings involving the same assessee governed the classification issue, so the exemption could not be extended to the component assemblies. On limitation, the demand was not wholly time-barred because the notice covered a period that included a non-time-barred segment, but the amount had to be segregated and recomputed. The matter therefore required de novo quantification for the surviving period.
Issues: (i) Whether Bowl Assembly, Column Assembly and Discharge Head Assembly together constituted a power driven pump entitled to exemption under Notification No. 56/95, or whether only the Bowl Assembly was the pump and the other two items were parts or accessories chargeable to duty; (ii) whether the demand was wholly barred by limitation and, if not, whether the matter required remand for requantification.
Issue (i): Whether Bowl Assembly, Column Assembly and Discharge Head Assembly together constituted a power driven pump entitled to exemption under Notification No. 56/95, or whether only the Bowl Assembly was the pump and the other two items were parts or accessories chargeable to duty.
Analysis: The disputed issue had already been decided in earlier appeals involving the same assessee for prior periods. The Tribunal had held that the Bowl Assembly alone is to be treated as the power driven pump, while the Column Assembly and Discharge Head Assembly are only parts or accessories and therefore do not qualify for the exemption available to the pump itself.
Conclusion: The issue was decided against the assessee and in favour of Revenue.
Issue (ii): Whether the demand was wholly barred by limitation and, if not, whether the matter required remand for requantification.
Analysis: The period involved was October 1991 to April 1992 and the show-cause notice was issued on 5-8-1992, so the entire demand could not be treated as time-barred. However, since part of the demand required segregation of the non-time-barred period, the matter had to be sent back for fresh quantification after giving the assessee an opportunity in de novo proceedings.
Conclusion: The limitation objection succeeded only to the extent of requiring requantification for the non-time-barred period, and the matter was remanded for that limited purpose.
Final Conclusion: The merits were decided against the assessee, but the demand could not be sustained in its present form and required fresh quantification for the non-time-barred period.
Ratio Decidendi: Where earlier binding findings have classified component assemblies as parts or accessories rather than the exempted finished equipment, exemption cannot be extended to those components, and a demand may still survive to the extent it relates to a non-time-barred period requiring recomputation.
