Excess duty on RT-12 assessment can be adjusted through account-current credit, without a separate refund claim.

Excess central excise duty discovered on assessment of RT-12 returns under Rule 173-I was required to be adjusted by taking credit in the account-current where the assessment merely gave effect to approved price lists or classification. In that situation, the Superintendent was not making a fresh redetermination of value, and a separate refund application under Section 11B was not contemplated. The limitation bar under Section 11B therefore did not arise. The document distinguishes cases involving re-determination of value or issues outside Rule 173-I, and states that the assessee was entitled to suo motu credit of the excess duty.

Issues: Whether excess duty found on assessment of RT-12 returns under Rule 173-I of the Central Excise Rules, 1944 had to be dealt with by credit in the account-current or by filing a separate refund claim under Section 11B of the Central Excises and Salt Act, 1944.

Analysis: The duty paid in excess arose after the price lists were approved and the RT-12 returns were assessed on that basis. On the facts, the Superintendent was not revising value or deciding classification independently but was merely giving effect to the approved price lists and the assessment mechanism under Rule 173-I(2). That rule expressly requires the assessee to take credit for excess duty in the account-current when the assessed duty is less than the duty already paid. In such a situation, a separate refund application is not contemplated, and the bar of limitation under Section 11B does not arise. The contrary view was distinguished as applicable to cases involving re-determination of value or matters outside the scope of Rule 173-I.

Conclusion: The assessee was entitled to take suo motu credit of the excess duty under Rule 173-I, and no separate refund claim was required.

Ratio Decidendi: Where excess duty is discovered on assessment of RT-12 returns in consequence of an approved price list or classification, Rule 173-I governs the adjustment and permits credit in the account-current without a separate refund claim under Section 11B.
