Central Government department use and captive exemption placed Potassium Metal outside excise duty liability

Potassium Metal supplied to the Heavy Water Plant at Thal was treated as eligible for exemption under Notification No. 200/86 because the plant was owned by the Department of Atomic Energy and operated by Rashtriya Chemicals & Fertilisers Ltd. only on behalf of that Department, so the goods were regarded as intended for use by a Central Government department. Potassium Metal captively used in the manufacture of heavy water was also covered by the Central Government's exemption order issued under section 5A(2) of the Central Excise Act, 1944, and was therefore outside duty liability. On that basis, the duty demand on both supplied and captive quantities was not sustainable.

Issues: (i) Whether Potassium Metal supplied to the Heavy Water Plant at Thal was eligible for exemption under Notification No. 200/86 as goods manufactured by a factory belonging to the Central Government and intended for use by a department of that Government; (ii) Whether Potassium Metal used captively in the manufacture of heavy water was exempt from duty under the Central Government's order issued under section 5A(2) of the Central Excise Act, 1944.

Issue (i): Whether Potassium Metal supplied to the Heavy Water Plant at Thal was eligible for exemption under Notification No. 200/86 as goods manufactured by a factory belonging to the Central Government and intended for use by a department of that Government.

Analysis: The notification exempted goods manufactured by factories belonging to the Central Government and intended for use by the departments of that Government. The agreement for the Thal plant showed that the Department of Atomic Energy was to be the owner of the plant, while Rashtriya Chemicals & Fertilisers Ltd. was only entrusted with construction, commissioning, operation and maintenance on behalf of the Department. On that basis, the plant retained its character as a Central Government department for the purpose of the notification, and the use of the goods was treated as use by the department of the Central Government.

Conclusion: The exemption under Notification No. 200/86 was available to the Potassium Metal supplied to the Heavy Water Plant at Thal, and the demand of duty on that score was not sustainable.

Issue (ii): Whether Potassium Metal used captively in the manufacture of heavy water was exempt from duty under the Central Government's order issued under section 5A(2) of the Central Excise Act, 1944.

Analysis: The captive quantity of Potassium Metal was covered by the Central Government's order granting exemption for the relevant period. The order was treated as sufficient to take the captively used material out of the duty liability.

Conclusion: The captively consumed Potassium Metal was exempt from duty.

Final Conclusion: The duty demand on Potassium Metal could not be sustained, and the assessee was entitled to exemption on both the supplied and captively consumed quantities.

Ratio Decidendi: Where a plant is owned by the Central Government and operated by another entity only on behalf of that Government, goods intended for use in that plant satisfy a notification requiring use by a Central Government department, and captive use covered by a specific exemption order is likewise outside duty liability.
