Exemption for clinical samples barred excise credit on inputs, as the notified quantity was treated as wholly exempt finished goods.

Clinical samples of patent and proprietary medicines cleared under an exemption notification were treated as wholly exempt finished excisable goods for the identified quantity, so the proviso to Rule 56-A of the Central Excise Rules, 1944 barred credit of duty on materials used in their manufacture. The fact that the exemption operated as a concession and was linked to a quantified clearance limit did not take the samples outside the proviso, because the relevant quantity remained outside the excise levy. The challenge to the excise demand therefore failed, and the authorities' orders were upheld.

Issues: Whether clinical samples of patent and proprietary medicines cleared under the exemption notification were "finished excisable goods" wholly exempted from excise duty so as to attract the proviso to Rule 56-A of the Central Excise Rules, 1944 and deny credit of duty on materials used in their manufacture.

Analysis: Rule 56-A permitted credit of duty on materials or component parts used in the manufacture of specified excisable goods, but the proviso withheld such credit where the finished excisable goods produced by the manufacturer were exempted from the whole of the excise duty leviable thereon. The notification for clinical samples granted exemption only up to a quantified limit linked to the manufacturer's clearances. The Court held that this was nonetheless a complete exemption for the identified quantity of clinical samples, and that the concession could not be treated as falling outside the proviso. The argument based on strict construction of the proviso did not assist the petitioners, because the notification still placed the relevant quantity of samples outside the excise levy.

Conclusion: The proviso to Rule 56-A applied, and the petitioners were not entitled to credit of duty on materials used for the exempt clinical samples.

Final Conclusion: The challenge to the excise demand failed, and the orders of the authorities were upheld.

Ratio Decidendi: Where finished goods or a defined quantity of such goods are wholly exempt from excise duty under a notification, the proviso to Rule 56-A of the Central Excise Rules, 1944 bars duty credit on materials used in their manufacture, even if the exemption operates as a concession or is quantity-limited.
