Rule 57F(4) does not create duty on waste from Modvat inputs; exemption claims must be tested on merits.

Waste arising from the processing of inputs on which Modvat credit had been taken was not automatically dutiable under Rule 57F(4). The provision only permitted removal of such waste on payment of duty as if manufactured in the factory; it did not by itself create a separate duty liability. Liability had still to be tested against the relevant tariff entry and any applicable exemption notification. The claimed exemption under Notification No. 53/88 therefore had to be examined on merits, and the orders below were set aside for fresh determination of exemption and refund entitlement.

Issues: Whether waste arising from the processing of inputs on which Modvat credit had been taken became automatically dutiable under Rule 57F(4), and whether the claim to exemption under Notification No. 53/88 had to be examined on merits.

Analysis: Rule 57F(4) merely permits removal of such waste on payment of duty as if it were manufactured in the factory. That provision does not by itself create a separate liability to duty. The liability must still be tested with reference to the relevant tariff entry and any applicable exemption notification. The claimed exemption could not be rejected solely on the ground that Rule 57F(4) applied, and the exemption issue required substantive consideration.

Conclusion: The waste was not automatically chargeable to duty merely because Modvat credit had been taken on the inputs. The exemption claim was required to be examined on merits, and the appeals succeeded.

Final Conclusion: The orders below were set aside and the matter was left for fresh determination of exemption and refund entitlement in accordance with the applicable refund provision.

Ratio Decidendi: Rule 57F(4) does not independently impose duty on waste arising from credit availed inputs; duty liability depends on the tariff entry and any available exemption notification.
