Exemption for integral plant components extends to maintenance spares used in humidification plant insulation under Notification No. 1/95-C.E.

Insulating material used in a humidification plant was held to qualify for exemption under Notification No. 1/95-C.E. because it formed an integral part of the plant's temperature and humidity control function. The material was treated as covered by the notification's reference to materials and spares, and its use for maintenance did not exclude it from exemption. On that reasoning, duty-free benefit was available and the Revenue's challenge failed.

Issues: Whether insulating material used in a humidification plant was eligible for the benefit of Notification No. 1/95-C.E. dated 04.01.1995.

Analysis: The humidification plant required insulation material as an integral component for maintaining temperature or humidity. The notification covered duty-free receipt of materials and spares thereof. Even if the material was treated as used for maintenance, it would still fall within the expression "spares".

Conclusion: The exemption under Notification No. 1/95-C.E. dated 04.01.1995 was available and the Revenue's challenge failed.

Ratio Decidendi: Where exempted materials are supplied as part of a plant's integral functioning or qualify as spares, the benefit of the exemption notification cannot be denied on the ground that they are used for maintenance.
