Excise valuation needs true comparability and prior penalty notice; unsupported price comparison and extended limitation both failed.

Comparable goods may be used for excise valuation only after true comparability is established and material differences in quality, process and other relevant factors are adjusted; on the facts, the outside purchase price could not be adopted as the assessable value, so the duty demand based on it failed. In the absence of wilful misstatement or suppression of facts, the extended limitation period under Section 11A could not be invoked; the demand was therefore time-barred. Penalty could not be sustained because the amended show cause notice contained no specific proposal for penal action; the penalty was set aside.

Issues: (i) Whether the price of sodium silicate purchased from other manufacturers could be treated as the assessable value of the sodium silicate manufactured and captively consumed by the assessee. (ii) Whether the duty demand was barred by limitation in the absence of wilful mis-statement or suppression of facts. (iii) Whether penalty could be imposed when the amended show cause notice contained no proposal for penalty.

Issue (i): Whether the price of sodium silicate purchased from other manufacturers could be treated as the assessable value of the sodium silicate manufactured and captively consumed by the assessee.

Analysis: Comparable goods are not established merely because the goods bear the same description or belong to the same genre. Relevant differences affecting value, including differences in quality, process, size of unit, manufacture, and other material characteristics, must be accounted for by suitable adjustments. The department relied only on the outside purchase price without establishing comparability on the basis of analytical or other reliable data.

Conclusion: The outside purchase price could not be adopted as the assessable value, and the duty demand founded on that basis was unsustainable.

Issue (ii): Whether the duty demand was barred by limitation in the absence of wilful mis-statement or suppression of facts.

Analysis: In the absence of a definition of comparable goods, the assessee could not be faulted for not declaring comparability in the price list. The department was equally aware, or could with due diligence have ascertained, the existence and prices of the alleged comparable goods. The facts did not justify a finding of wilful mis-statement or suppression so as to invoke the extended period under Section 11A.

Conclusion: The demand was held to be entirely time-barred.

Issue (iii): Whether penalty could be imposed when the amended show cause notice contained no proposal for penalty.

Analysis: Penalty cannot be sustained where the amended notice calling upon the assessee to show cause against duty demand did not propose any penal action. In the absence of a specific proposal in the notice, the levy of penalty was not permissible.

Conclusion: The penalty was not sustainable and was set aside.

Final Conclusion: The demand and penalty were set aside, and the appeal succeeded with consequential relief to the assessee.

Ratio Decidendi: For excise valuation, the price of allegedly comparable goods can be used only after establishing true comparability and making necessary adjustments for material differences; absent wilful mis-statement or suppression, the extended limitation period cannot be invoked, and penalty cannot be imposed without a prior proposal in the show cause notice.
