Excess duty paid during annual provisional assessment must be adjusted against alleged short-payment.

Hindustan Zinc Limited’s mining unit manufactured lead and zinc concentrate, much of which was captively consumed by the company’s smelting units.

Because the assessable value depended on annual production costs and laboratory testing, the unit paid duty provisionally.

On finalisation of the provisional assessment for financial year 2004–05, the Deputy Commissioner fixed total duty liability at Rs. 33,65,43,811, while the appellant had paid Rs. 34,19,68,596; nevertheless, the authority demanded Rs. 1,16,53,609 as short-paid duty for 1 April to 19 December 2004, while recognising excess payment for the remainder of the year.

The Commissioner (Appeals) and the CESTAT dismissed the appellant’s challenges, relying, among other things, on the passing-on of duty and the recipient units’ CENVAT credit.

The appellant sought adjustment of the excess payment against the demand, not a cash refund.

Whether, upon finalisation of provisional assessment based on annual costing, the financial year could be divided into periods of short-payment and excess payment without considering the overall duty position.

Whether excess duty paid during the relevant year could be adjusted against the alleged short-payment, notwithstanding the rules governing refunds and unjust enrichment.

Whether the appellant was entitled to interest on the excess duty, and whether the Department could demand interest on the alleged short-payment before giving effect to the adjustment.

Rule 7(3) of the Central Excise Rules, 2002 requires final assessment once the relevant information is available; Rules 7(4) and 7(5) address interest on amounts payable and refunds, while Rule 7(6) governs the treatment of refunds and the unjust-enrichment exceptions.

Where provisional assessment is finalised using annual cost of production, the corresponding duty liability must be determined consistently by accounting for duty already paid during the relevant assessment period; a refund restriction does not require the Department to disregard payments when calculating net liability.

The Court relied on Toyota Kirloskar Auto Parts Pvt. Ltd. v. C.C.E., LTU, Bangalore and Godrej Consumer Products Ltd., which support considering the overall duty position where annual costing is used.

It also applied the principle in Associated Cement Co. Ltd. v. Commercial Tax Officer, Kota that machinery provisions of a taxing statute should be interpreted to give effect to the statutory scheme and its purpose.

No interest is payable to the appellant where no refund is ordered; conversely, interest on an alleged short-payment cannot be demanded without first determining whether any net amount remains payable after adjustment.

The final assessable value was determined through annual costing, and the final assessment recorded that the appellant’s payments for the year exceeded its total annual duty liability.

The Department could not rely on that annual costing to determine value while isolating an earlier period’s alleged shortfall and ignoring excess duty paid later in the same year; no statutory provision authorising that approach was identified.

The appellant sought only an accounting adjustment, not a cash refund, so the refund restrictions and the recipient units’ CENVAT credit did not justify excluding the excess payment when calculating net duty liability.

Since no refund was being ordered, the appellant was not entitled to interest on the excess; any departmental interest on short-payment depended on the outcome of the adjustment.

It held that the appellant was not entitled to interest on the excess duty, but the Department could not demand interest on an alleged short-payment without first giving effect to the adjustment.

The appeal was allowed; the CESTAT order and the demand of Rs. 1,16,53,609, together with consequential interest, were set aside to the extent they denied the adjustment.

No cash refund or interest on the excess duty was ordered, and the Department was directed to carry out the consequential exercise in accordance with the recorded annual liability and payments.
