Central excise valuation of captive clearances hinges on comparable sales, while extended limitation fails without deliberate suppression.

Captively consumed caustic soda lye cleared to related units was required to be valued under Section 4 of the Central Excise Act by reference to the assessee's own comparable sales to independent buyers, because Rule 6(b)(i) of the Valuation Rules applied only where value could not otherwise be determined; the duty short-payment on merits was therefore sustained. However, the extended limitation period could not be invoked because the department already had the price declarations, invoices and RT-12 returns, and suppression under the proviso to Section 11A required deliberate withholding with intent to evade duty; the demand was time-barred and the penalty under Section 11AC was unsustainable.

Issues: (i) Whether the assessable value of captively consumed caustic soda lye cleared to related units was to be determined under Rule 6(b)(i) of the Central Excise (Valuation) Rules, 1975 on the basis of the receiving units' purchase price from other buyers, or on the basis of the appellant's own average sale price to independent buyers; (ii) whether the demand was barred by limitation for want of suppression of facts or wilful misstatement, and whether penalty was sustainable.

Issue (i): Whether the assessable value of captively consumed caustic soda lye cleared to related units was to be determined under Rule 6(b)(i) of the Central Excise (Valuation) Rules, 1975 on the basis of the receiving units' purchase price from other buyers, or on the basis of the appellant's own average sale price to independent buyers.

Analysis: The goods were cleared to units where they were captively consumed. The appellant itself had sales to independent buyers, and the jurisdictional Assistant Commissioner had approved valuation for one unit on the basis of the average sale price to independent buyers of the previous month. In such a situation, the assessable value could be determined under Section 4 of the Central Excise Act, 1944 by reference to the appellant's own comparable sales. Rule 6 of the Valuation Rules applied only where value could not be determined under the earlier rules. Since the appellant had contemporaneous sales to independent buyers, Rule 6(b)(i) had no application, and the lower values based on the recipient units' own purchase prices were not justified.

Conclusion: The valuation adopted by the appellant was not correct, and the duty short-payment on merits was upheld against the assessee.

Issue (ii): Whether the demand was barred by limitation for want of suppression of facts or wilful misstatement, and whether penalty was sustainable.

Analysis: The record showed that the department had access to the relevant price declarations, sale invoices, and RT-12 returns disclosing the clearances to the different units. The earlier departmental letter itself showed awareness of the differing values. Applying the settled principle that suppression under the proviso to Section 11A(1) of the Central Excise Act, 1944 requires deliberate withholding of information with intent to evade duty, the extended period could not be invoked. Since the demand was beyond the normal period, the penalty under Section 11AC also could not survive.

Conclusion: The demand was time-barred, and the penalty was unsustainable, in favour of the assessee.

Final Conclusion: Although the valuation on merits was found to be incorrect, the demand was held to be barred by limitation, resulting in the setting aside of the duty confirmation and penalty.

Ratio Decidendi: Extended limitation under the Central Excise law is invocable only on proof of deliberate suppression or wilful misstatement with intent to evade duty, and where the department is already aware of the relevant facts, the demand must be confined to the normal limitation period.
