Modvat credit on input used in manufacture protected where waste or by-products remain, pending fresh administrative reconsideration.

Rule 57D(1) of the Central Excise Rules, 1944 protects Modvat credit where part of the duty-paid input is contained in waste, refuse or by-products arising in manufacture, and the cited earlier precedent states that full Modvat benefit remains available once the entire input is shown to have been used even if spent acid remains. On that basis, the matter was sent back for fresh consideration by the competent authority with reference to the earlier judgment, and recovery under the impugned notice was stayed until that decision is taken.

Issues: Whether the matter concerning recovery of alleged excess Modvat benefit should be reconsidered by the authorities in the light of the earlier decision on Rule 57D(1).

Analysis: The petitioners had taken Modvat credit on sulphuric acid used in manufacture, and the Court noted that Rule 57D(1) of the Central Excise Rules, 1944 protects credit where part of the input is contained in waste, refuse or by-products arising in the course of manufacture. The Court also noted its earlier decision holding that full Modvat benefit is available once the entire duty-paid input is proved to have been put to use, even if some spent acid remains. Since that decision was not before the respondents when the impugned notice was issued, the Court found it appropriate that the matter be re-examined by the competent authority with reference to that precedent.

Conclusion: The matter was remitted to the concerned authorities for fresh decision after considering the earlier judgment, and recovery under the impugned notice was stayed until such decision.
