Exemption for rubber solution and captive consumption shield duty where eligibility under the notifications was established.

Rubber solution was treated as classifiable under Heading 40.05, making Notification No. 377/86-CE applicable for October 1986 to February 1987 because the product satisfied the stated concessional rate conditions, and the benefit could be extended at the appellate stage even though it had not been claimed earlier. For March 1987 to May 1988, no duty liability arose on captive consumption since the intermediate product was used within the same factory and was covered by the relevant exemption notifications. Duty was therefore to be recalculated only to reflect the admissible exemption benefits.

Issues: (i) Whether the product rubber solution was eligible for the benefit of Notification No. 377/86-CE for the period October 1986 to February 1987; (ii) whether no duty liability arose for the period March 1987 to May 1988 on account of captive consumption and exemption under Notification No. 217/86-CE and Notification No. 82/87-CE.

Issue (i): Whether the product rubber solution was eligible for the benefit of Notification No. 377/86-CE for the period October 1986 to February 1987.

Analysis: The product was held to fall under Heading 40.05, and the notification granted concessional duty at 15 per cent ad valorem to compounded rubber falling under that heading. The denial of the benefit on the ground that it had not been claimed before the lower authorities was not accepted, since a lawful exemption or concessional benefit can be extended at the appellate stage when the underlying eligibility is established.

Conclusion: The benefit of Notification No. 377/86-CE was held admissible to the assessee for the period October 1986 to February 1987, and duty was required to be recalculated accordingly.

Issue (ii): Whether no duty liability arose for the period March 1987 to May 1988 on account of captive consumption and exemption under Notification No. 217/86-CE and Notification No. 82/87-CE.

Analysis: The rubber solution was used captively in the manufacture of final products within the same factory. Once the captively consumed goods were covered by the relevant exemption notifications, the duty burden on such intermediate product was not attracted for the stated period.

Conclusion: No duty liability was held to arise for the period March 1987 to May 1988.

Final Conclusion: The appeal succeeded only to the extent of securing the appropriate exemption benefits and consequential recalculation of duty, while the classification of rubber solution under Heading 40.05 remained settled against the assessee.

Ratio Decidendi: A concessional or exemption notification must be applied to an otherwise eligible product even at the appellate stage, and captive consumption of goods covered by an exemption notification does not attract duty for the relevant period.
