Excise exemption for naphtha extends to captive power, steam generation and pipeline flushing when integral to manufacture.

Naphtha captively consumed for generating electricity and steam was treated as eligible for excise exemption where those utilities were essential and integrally connected with the manufacture of final products under Chapter 27. The notification's phrase "in or in relation to the manufacture" was applied broadly, so the presence of intermediate products did not break the nexus when the input formed part of the manufacturing chain. Naphtha used for flushing pipelines was also covered because the activity was a necessary preliminary step to make the pipelines fit for moving raw material into the production process. The commentary states that indirect use through essential intermediate processes can satisfy the exemption condition when it is integral to manufacture.

Issues: (i) Whether naphtha captively consumed for generation of electricity and steam used in the manufacture of final products falling under Chapter 27 was eligible for Central Excise duty exemption under Notification No. 217/86-C.E., as amended by Notification No. 61/94-C.E.; and (ii) whether naphtha used for flushing of pipelines was eligible for the same exemption.

Issue (i): Whether naphtha captively consumed for generation of electricity and steam used in the manufacture of final products falling under Chapter 27 was eligible for Central Excise duty exemption under Notification No. 217/86-C.E., as amended by Notification No. 61/94-C.E.

Analysis: The exemption notification contemplated specified inputs being used "in or in relation to the manufacture of the final products". Naphtha was an input under Chapter 27, and the final products were also under Chapter 27. The naphtha was used in the co-generation plant to produce hot gases, electricity, and steam, and the electricity and steam were found to be essential and integrally connected with the manufacturing process of the final products. The existence of intermediate products did not defeat the exemption where the indirect use of the input was part of the manufacturing chain and there was a sufficient nexus with the final products. The same principle was applied by reference to the settled understanding of inputs used in relation to manufacture.

Conclusion: The exemption was admissible on naphtha used for generation of electricity and steam, and the denial of exemption on that ground was unsustainable.

Issue (ii): Whether naphtha used for flushing of pipelines was eligible for the same exemption.

Analysis: Flushing of pipelines was found to be necessary to make the pipelines fit for transporting crude or other petroleum products into the plant for further processing. The process was treated as integrally connected with manufacture, since without it the raw material could not be effectively brought into the production stream. The absence of immediate transformation at that stage did not matter where the activity was a necessary preliminary step in the manufacturing chain.

Conclusion: The exemption was admissible on naphtha used for flushing of pipelines as well.

Final Conclusion: The appeals succeeded in full, the exemption claim on the disputed uses of naphtha was upheld, and the demands confirmed on that basis were set aside.

Ratio Decidendi: An input used indirectly through essential intermediate processes is covered by an exemption for goods used "in or in relation to the manufacture" of the final products when the use is integral to and necessary for the production of those final products.
