Modvat credit reversal on common inputs for exempted goods requires full reversal, while extended limitation needs clear proof of disclosure.

Where common inputs are used in exempted final products under the Modvat credit scheme, credit is required to be reversed on the full quantity of inputs used for the exempted goods, not merely on the portion physically present in the finished product. A proportionate reversal based only on input content was rejected as inconsistent with the statutory scheme. On limitation, the extended period could not be sustained without clear proof that the relevant facts had been disclosed or were otherwise known to the department; mere filing of returns was held insufficient by itself. The limitation and related quantification aspects were remitted for fresh consideration.

Issues: (i) whether, in the case of common inputs used in the manufacture of exempted final products, credit was required to be reversed in full or only to the extent of inputs actually contained in the exempted products; (ii) whether the demand could be sustained by invoking the extended period of limitation.

Issue (i): whether, in the case of common inputs used in the manufacture of exempted final products, credit was required to be reversed in full or only to the extent of inputs actually contained in the exempted products.

Analysis: The credit scheme under the Modvat rules proceeds on the basis that inputs used in exempted final products are not entitled to credit. The relevant provisions were read as requiring the assessee to forgo credit on the entire quantity of inputs used for the exempted product, not merely on the portion that physically remained in the final product after waste or scrap emerged. A proportionate reversal based on the quantity contained in the finished exempted goods was held inconsistent with the statutory scheme, and the attempt to confine reversal to inputs content was rejected.

Conclusion: The assessee was required to reverse credit in full on inputs used for exempted final products, and the assessee's contention on partial reversal was rejected.

Issue (ii): whether the demand could be sustained by invoking the extended period of limitation.

Analysis: The finding on limitation was not sustained as recorded. The record did not clearly establish that the alleged departmental knowledge was based on disclosed facts or that the reversal method had been properly intimated to the department. Mere filing of returns and related disclosures was held insufficient, by itself, to prove knowledge of the full factual position. At the same time, the matter required reconsideration by the adjudicating authority in light of the observations on knowledge, disclosure, and the period involved.

Conclusion: The limitation issue was set aside and remanded for fresh decision.

Final Conclusion: The substantive view on credit reversal was against the assessee, but the limitation and connected quantification issues were remitted for reconsideration, so the appeals were disposed of by remand.

Ratio Decidendi: Where common inputs are used for exempted final products, the statutory credit scheme requires reversal of credit on the full quantity of inputs used, and an extended limitation plea cannot be sustained without clear proof of disclosure or departmental knowledge of the relevant facts.
