Exemption notification for oil-processing by-products cannot be narrowed by unstated conditions; pre-notice duty payment also defeats penalty.

An exemption notification was construed to cover goods manufactured in a specified oil mill and solvent extraction industry without adding a requirement that the raw material must be wholly extracted in the assessee's own factory. On that reading, fatty acids and residues/by-products arising during refining of purchased crude oil were entitled to exemption, and duty on those by-products was not justified. Penalty was also held unsustainable because the duty had already been paid before the show cause notice, so the penal basis did not survive on the facts recorded.

Issues: (i) Whether duty could be levied on fatty acids and residues/by-products arising in the factory and whether the benefit of Notification No. 115/75-C.E. dated 30-4-1975 was available even though crude oil was purchased from the open market and only refined in the factory; (ii) Whether penalty was sustainable where the duty had been paid before issuance of the show cause notice.

Issue (i): Whether duty could be levied on fatty acids and residues/by-products arising in the factory and whether the benefit of Notification No. 115/75-C.E. dated 30-4-1975 was available even though crude oil was purchased from the open market and only refined in the factory.

Analysis: The exemption under Rule 8(1) of the Central Excise Rules, 1944 covered goods manufactured in factories falling within the specified industries, including oil mill and solvent extraction industry. The notification did not impose any condition that the raw material must be wholly extracted within the factory or that the assessee must itself carry on only extraction activity. Since the appellants' factory fell within the specified industry and the disputed items were by-products of the manufacturing process, the benefit of the notification could not be denied merely because crude oil was purchased and refined.

Conclusion: The levy of duty on the fatty acids and residues was not justified and the assessee was entitled to exemption.

Issue (ii): Whether penalty was sustainable where the duty had been paid before issuance of the show cause notice.

Analysis: The entire duty demand had been discharged before the issuance of the show cause notice. In that situation, the basis for imposing penalty on the assessee did not survive on the facts accepted in the order.

Conclusion: The penalty was not sustainable and was set aside.

Final Conclusion: The duty demand on the disputed by-products was held not recoverable under the exemption notification, and the penalty was also deleted, resulting in modification of the impugned order in favour of the assessee on both substantive and penal aspects.

Ratio Decidendi: An exemption notification must be construed on its own terms, without adding unstated conditions, and where the notification covers goods manufactured in a specified industry, the benefit cannot be denied merely because the raw material was purchased rather than wholly produced in the assessee's factory; penalty is unwarranted where the duty has already been paid before issuance of the show cause notice.
