Broad interpretation of Modvat input rules upheld for caustic soda lye used in effluent treatment and gas neutralisation.

The phrase used in or in relation to the manufacture of final products under Rule 57A was construed broadly to extend Modvat credit to inputs that participate indirectly in the manufacturing process. Effluent treatment was treated as an essential and integral part of manufacture, so inputs used for pollution control and neutralising gases before emission were regarded as part of the manufacturing process. On that basis, Caustic Soda Lye used in the effluent treatment process qualified as an eligible input for Modvat credit, and the assessee was entitled to the credit.

Issues: Whether Caustic Soda Lye used for neutralising gases in the pollution control and effluent treatment process was an input used in or in relation to the manufacture of the final product so as to qualify for Modvat credit under the applicable rules.

Analysis: The expression used in or in relation to the manufacture of final products under Rule 57A is to be construed broadly so as to widen the ambit of inputs eligible for Modvat credit. It covers not only goods directly entering the final product but also those indirectly participating in the manufacturing process. Effluent treatment is an essential and integral part of manufacture, and apparatus or inputs used for such treatment form part of the manufacturing process. On that basis, Caustic Soda Lye used for neutralising gases before emission was treated as falling within the scope of eligible inputs.

Conclusion: The assessee was entitled to Modvat credit on Caustic Soda Lye and the appeal succeeded on merits.
