Credit of deemed duty on specified steel inputs allows manufacturers to claim excise credit for final product liabilities. Inputs specified (hot re-rolled products, ingots and billets of non-alloy steel) on which excise duty under section 3A has been paid are declared to bear deemed duty equal to an amount calculated on the invoice price, and credit of that deemed duty is allowed to the manufacturer of the final products. Credit may be used only for payment of excise on those final products; inputs exported under bond may have credit utilised elsewhere or refunded if adjustment is impossible, subject to conditions. Credit applies only where inputs are received directly from the input manufacturer's factory under an invoice correctly declaring duty paid and the invoice price; the notification is effective 1 April to 30 April 2000.
