Exemption for wind turbine parts denied where HR plates were only raw material; extended limitation and penalty were also rejected.

HR plates used as raw material for fabricating wind turbine towers were held not to be identifiable parts or components of the wind operated electricity generator, so the exemption under Notification No. 12/2012-CE was denied on merits. The distinction between inputs used to manufacture a part and the part itself was accepted, and mere use in tower fabrication did not satisfy the exemption condition. On limitation, the absence of suppression, fraud, collusion, or misstatement meant the extended period could not be invoked, and the penalty was not sustainable. The substantive demand survived only for the normal period.

Issues: (i) Whether HR plates used in the manufacture of towers for wind operated electricity generators qualify as parts or components of the wind operated electricity generator for exemption under Notification No. 12/2012-CE. (ii) Whether the extended period of limitation and the penalty were sustainable.

Issue (i): Whether HR plates used in the manufacture of towers for wind operated electricity generators qualify as parts or components of the wind operated electricity generator for exemption under Notification No. 12/2012-CE.

Analysis: The exemption covered wind operated electricity generators, their components and parts, and also parts consumed within the factory for manufacture of specified goods. The distinction drawn between a finished part and the raw material used to manufacture that part was accepted. HR plates were found to be inputs used for fabrication of towers and not identifiable parts or components of the tower itself. Mere use of the plates in making towers did not convert them into parts of the tower or of the wind operated electricity generator.

Conclusion: The claim for exemption on HR plates failed on merits.

Issue (ii): Whether the extended period of limitation and the penalty were sustainable.

Analysis: The procurement of duty-free goods had been permitted under the relevant concessional duty procedure, and the record did not justify allegations of suppression, fraud, collusion, or misstatement. The normal limitation under Section 11A of the Central Excise Act, 1944 was held applicable even where proceedings were initiated with reference to the concessional-rate rules. Since the extended period was not available, the penalty could not be sustained.

Conclusion: The extended period was not invocable and the penalty was set aside.

Final Conclusion: The appeal succeeded only to the extent of limitation and penalty, while the substantive demand was sustained for the normal period.

Ratio Decidendi: Raw material used to manufacture a part is not itself a component or part of the final exempted machine, and the extended period of limitation cannot be invoked in the absence of suppression or other qualifying conduct.
