Modvat credit on process loss upheld where the Department failed to prove short receipt or disallowance of input credit.

Modvat credit on caustic soda lye could not be denied where the Department failed to prove that the recorded soda loss was a short receipt before manufacture rather than a process loss in producing calcined alumina. The assessee's import, storage, transfer and issue records, including material transfer advices and duty-paying documents, supported a disclosed accounting system, while earlier proceedings on the same allegations had already been dropped after verification. A later audit report, without authenticated material, could not by itself displace those findings or fix binding consumption norms. The Department did not discharge the initial burden of proving ineligible loss, and the principle that exact one-to-one correlation between input and final product is unnecessary supported allowance of credit.

Issues: Whether Modvat credit on caustic soda lye could be denied and duty with penalty demanded on the footing that the recorded unaccounted soda loss represented short receipt of input before manufacture rather than process loss occurring in the manufacture of calcined alumina.

Analysis: The available material did not establish any reliable documentary basis for the allegation of short receipt or pre-manufacture transit loss. The assessee had a disclosed and documented procedure for import, storage, transfer, and issue of the input, supported by material transfer advices and duty-paying documents. Earlier proceedings on the same allegations had been dropped after verification, including a prior special audit. The later audit report did not furnish authenticated material to override those earlier findings or to fix binding consumption norms on its own. The Department therefore failed to discharge the initial burden of proving that the disputed loss was not part of the manufacturing process. The reasoning also treated the claimed loss as covered by the Modvat scheme, particularly in light of the principle that exact one-to-one correlation between input quantity and final product is not required.

Conclusion: The denial of Modvat credit, the duty demand, and the penalty were unsustainable and were set aside in favour of the assessee.
