Integrated manufacturing inputs can qualify as raw material for exemption even when consumed or partly burnt in production.

Carbon paste used in the manufacture of calcium carbide was treated as an eligible input for exemption under Notification No. 201/79-C.E. because it was consumed in an integrated manufacturing process and contributed to the final product. The governing principle applied was that material used in production may qualify as raw material even if it is partly burnt, consumed in a chemical reaction, or does not retain its independent identity in the finished goods. On that footing, the earlier view that carbon paste was merely a device for conveying electricity was not accepted, and the exemption benefit was allowed.

Issues: Whether carbon paste used in the manufacture of calcium carbide could be treated as a raw material or component part entitled to the benefit of Notification No. 201/79-C.E. on the footing that it was consumed in the manufacturing process and contributed to the final product.

Analysis: The carbon paste was used in the course of manufacturing calcium carbide through electrodes in the furnace. The material was not merely a remote aid to manufacture but was consumed in the integrated process of production, and the final product also contained a percentage of carbon from the paste. The governing principle applied was that inputs used in an integrated manufacturing process, or consumed in a chemical reaction at an intermediate stage, may qualify as raw material for exemption even if they do not retain their identity in the finished product. On that footing, the earlier view that carbon paste was only a device for conveying electricity was not accepted.

Conclusion: Carbon paste was held to be eligible for the benefit of Notification No. 201/79-C.E., and the denial of exemption was set aside.

Final Conclusion: The appeals succeeded, and the assessee was held entitled to the exemption benefit in respect of carbon paste used for manufacturing calcium carbide.

Ratio Decidendi: Inputs consumed in an integrated manufacturing process and used in relation to the production of the final product can qualify as raw material for exemption, even if they are partly burnt or do not retain their independent identity in the finished goods.
