Related-unit captive consumption requires cost-based excise valuation, while disclosed revenue-neutral transfers do not support extended limitation or penalties.

Inter-unit transfers of engines and engine kits to related units for manufacture of diesel generating sets are valued under Rule 10(a) read with the proviso to Rule 9 and Rule 8 of the Central Excise Valuation Rules, requiring valuation at 110% of production cost. Rule 4 cannot apply without comparable independent sales of identical goods at the nearest relevant time, and the substituted valuation rules apply retrospectively without sequential application. Where recipient units sell engines as such, Rule 9 transaction value applies. Extended limitation and penalties are not justified where returns, audit records and correspondence disclosed the valuation method, no wilful suppression exists, and duty is available as CENVAT credit, making transactions revenue-neutral.

Issues: (i) Whether engines and engine kits stock-transferred to related inter-unit recipients for manufacture of diesel generating sets were assessable under Rule 8 rather than Rule 4 of the Central Excise Valuation (Determination of Price of Excisable Goods) Rules, 2000; (ii) Whether the extended limitation period and penalties were sustainable.

Issue (i): Whether engines and engine kits stock-transferred to related inter-unit recipients for manufacture of diesel generating sets were assessable under Rule 8 rather than Rule 4 of the Central Excise Valuation (Determination of Price of Excisable Goods) Rules, 2000.

Analysis: The inter-unit transfers were transactions with related persons and did not fall within Rules 4 to 7. Under Rule 10(a), valuation was governed by Rule 9; its proviso directed adoption of Rule 8 where the recipient unit used the engines in manufacturing diesel generating sets. Rule 4 could not be invoked without establishing that the comparative independent-sale values related to identical goods sold at the time nearest to the relevant removals. The substituted Rules 8, 9 and 10, read with the clarificatory circular, applied retrospectively; the valuation rules are not to be applied sequentially. For the limited transfers where engines were sold as such by the recipient unit, the normal transaction value under Rule 9 applied.

Conclusion: Valuation at 110% of cost of production under Rule 8 for engines used by recipient units in manufacture was valid, in favour of the assessee.

Issue (ii): Whether the extended limitation period and penalties were sustainable.

Analysis: Regular ER-1 returns, audit records and correspondence disclosed the adopted valuation method to the department; no positive act of wilful misstatement or suppression was established. A second extended-period notice on the same alleged suppression was also unsustainable. Further, duty paid by the supplying unit was available as CENVAT credit to the recipient units, making the exercise revenue-neutral; the same assessee's earlier revenue-neutrality finding had attained finality.

Conclusion: The extended-period demands and consequential penalties were unsustainable, in favour of the assessee.

Final Conclusion: Inter-unit clearances used for manufacture at related recipient units are governed by the captive-consumption valuation mechanism, and the disclosed, revenue-neutral transactions did not justify extended limitation or penal consequences.

Ratio Decidendi: Where goods transferred to a related unit are used by that unit in manufacturing further articles, Rule 10(a) read with the proviso to Rule 9 requires valuation under Rule 8, notwithstanding that part of the production is independently sold.
