Captive consumption dutiability limits Rule 57CC refund to excess amount over actual duty payable.

Captively consumed diesel engines used in manufacturing pump sets were treated as dutiable goods, so Rule 57CC of the Central Excise Rules did not apply to require reversal of 8% of value. On the refund issue, the amount debited under protest was not refundable in full where part of it corresponded to the duty actually payable on the captively consumed engines. Only the excess over the duty liability was refundable, and the refundable quantum had to be separately quantified by the original adjudicating authority.

Issues: (i) whether diesel engines captively consumed in the manufacture of pump sets were dutiable so that Rule 57CC of the Central Excise Rules could not be invoked to require reversal of 8% of value; (ii) whether the assessee was entitled to refund of the entire 8% amount debited or only the excess over the duty actually payable on the captively consumed engines.

Issue (i): Whether diesel engines captively consumed in the manufacture of pump sets were dutiable so that Rule 57CC of the Central Excise Rules could not be invoked to require reversal of 8% of value.

Analysis: The captively consumed diesel engines were treated as goods on which duty liability arose, and therefore they could not be regarded as exempted goods for the purpose of applying Rule 57CC. The earlier view that the assessee was not required to debit 8% under that rule was accepted on the legal issue of dutiability, and the Tribunal found no reason to differ from that conclusion.

Conclusion: The diesel engines were dutiable and Rule 57CC was not applicable.

Issue (ii): Whether the assessee was entitled to refund of the entire 8% amount debited or only the excess over the duty actually payable on the captively consumed engines.

Analysis: Although the 8% debit had been made under protest, the duty payable on the captively consumed diesel engines had not in fact been discharged. Once the assessee's contention on dutiability was accepted, the refund could not extend to the full amount debited if part of it represented the duty liability itself. Only the amount paid in excess of the duty actually payable was refundable, and the exact quantification required adjudication.

Conclusion: The assessee was entitled only to refund of the excess amount, and the matter had to be quantified by the original adjudicating authority.

Final Conclusion: The legal position on dutiability was accepted in favour of the assessee, but the refund claim was limited to the excess over the duty liability and was sent back for fresh quantification.

Ratio Decidendi: Where captively consumed goods are held dutiable, a refund of amounts debited under a mistaken Rule 57CC adjustment extends only to the excess over the duty actually payable, and the refundable quantum must be separately determined.
