SECTION 11AA. Interest on delayed payment of duty. —
(1) Notwithstanding anything contained in any judgment, decree, order or direction of the Appellate Tribunal or any court or in any other provision of this Act or the rules made thereunder, the person, who is liable to pay duty, shall, in addition to the duty, be liable to pay interest at the rate specified in sub-section (2), whether such payment is made voluntarily or after determination of the amount of duty under section 11A.
(2) Interest, at such rate not below ten per cent and not exceeding thirty-six per cent per annum, as the Central Government may, by notification in the Official Gazette, fix, shall be paid in terms of section 11A after the due date by the person liable to pay duty and such interest shall be calculated from the date on which such duty becomes due up to the date of actual payment of the amount due.
(3) Notwithstanding anything contained in sub-section (1), no interest shall be payable where,—
(a) the duty becomes payable consequent to the issue of an order, instruction or direction by the Board under section 37B; and
(b) such amount of duty is voluntarily paid in full, within forty-five days from the date of issue of such order, instruction or direction, without reserving any right to appeal against the said payment at any subsequent stage of such payment.
