Separate assessment of air-conditioning components and no extended limitation where facts were disclosed defeat the department's demand.

Electric control panels supplied with roof mounted package units were held not to form an integral part of a single air-conditioning system where the system came into existence only after site assembly of separate components; the components were therefore to be assessed separately and the department's valuation approach failed. The extended period of limitation was also unavailable because the assessee's separate classification and duty payment were already disclosed in returns, documents and audit records, so there was no suppression of facts. The impugned order was set aside and the assessee's appeal succeeded in full.

Issues: (i) Whether Electric Control Panels supplied along with Roof Mounted Package Units were to be treated as an integral part of a single air-conditioning system classifiable under Heading 8415 of the Central Excise Tariff Act, 1985, so as to require inclusion of their value in the assessable value of the package unit; (ii) Whether the demand could be raised by invoking the extended period of limitation.

Issue (i): Whether Electric Control Panels supplied along with Roof Mounted Package Units were to be treated as an integral part of a single air-conditioning system classifiable under Heading 8415 of the Central Excise Tariff Act, 1985, so as to require inclusion of their value in the assessable value of the package unit.

Analysis: The air-conditioning system comes into existence only after assembly at site of different machines and parts. The Board's circular on refrigeration and air-conditioning plants supported the view that such systems are assembled from various components and that the components are separately dutiable. On that basis, the Electric Control Panels could not be treated as an integral part of the Roof Mounted Package Units, and the two items could not be assessed together as one air-conditioning system.

Conclusion: The valuation adopted by the department was not sustainable, and the assessee succeeded on the classification and valuation issue.

Issue (ii): Whether the demand could be raised by invoking the extended period of limitation.

Analysis: The separate classification adopted by the assessee and payment of duty on that basis were already known to the department through returns, documents, and audit. In the absence of suppression of facts, invocation of the larger limitation period was unjustified.

Conclusion: The extended period of limitation was not available to the department, and the demand was time-barred.

Final Conclusion: The impugned order was set aside and the appeal succeeded in full.

Ratio Decidendi: Where an air-conditioning system is assembled at site from separate components, those components are to be separately assessed unless the department establishes that they constitute one identifiable excisable product, and the extended limitation period cannot be invoked without suppression of material facts.
