Modvat credit exclusion for furnace-related components blocks input treatment under Rule 57A and Notification No. 177/86.

Hot-tops, ramming mass and sealing compound were held to be components of furnace and ingot mould apparatus rather than inputs consumed in manufacture. Rule 57A allowed Modvat credit only for inputs used in or in relation to manufacture and expressly excluded machinery, plant, equipment, apparatus, tools and appliances. Notification No. 177/86, issued under that rule, could not enlarge the scope of admissible inputs beyond the exclusion. Credit was therefore not available and the allowance of Modvat credit was unsustainable.

Issues: Whether hot-tops, ramming mass and sealing compound were eligible inputs for Modvat credit under Rule 57A and Notification No. 177/86, or whether they fell within the exclusion for machinery, plant, equipment, apparatus, tools or appliances.

Analysis: Rule 57A permits credit only for inputs used in or in relation to the manufacture of final products, but expressly excludes machinery, plant, equipment, apparatus, tools and appliances. The disputed items were found to perform functions connected with the furnace and ingot moulds and therefore formed part of the apparatus or equipment rather than inputs consumed in manufacture. Notification No. 177/86, being issued under Rule 57A, had to be read subject to the rule's explanation and could not enlarge the scope of admissible inputs beyond the exclusion clause. The reliance on authorities concerning raw material was held inapposite because the present items were not raw materials entering into the product but components of equipment used in the manufacturing process.

Conclusion: The items were not eligible inputs for Modvat credit and the allowance of credit was unsustainable.
