Exemption for separately fractionated petroleum resin feed denied, while extended limitation applied and duty was remanded for recomputation.

Petroleum resin made from a separately fractionated pyrolysis gasoline cut did not qualify for exemption meant for raw naphtha and captive use of Chapter 27 goods, because the material used for resin manufacture was not the specified exempt input or an incidental by-product within the notification. Vague disclosure of the input and process justified invocation of the extended limitation period under the proviso to Section 11A, so the demand was not time-barred. However, the duty could not be sustained on the entire quantity sent to the resin plant and had to be recomputed on the correct diverted residue. Penalty was upheld in principle but substantially reduced.

Issues: (i) Whether petroleum resin manufactured from the pyrolysis gasoline stream qualified for concessional treatment under the exemption notifications governing raw naphtha and captive use of Chapter 27 goods; (ii) whether the demand was barred by limitation; (iii) whether the entire duty demand could be sustained; and (iv) whether the penalty was justified.

Issue (i): Whether petroleum resin manufactured from the pyrolysis gasoline stream qualified for concessional treatment under the exemption notifications governing raw naphtha and captive use of Chapter 27 goods.

Analysis: The exemption for raw naphtha was confined to use in the manufacture of the specified products. The record showed that the declared input for petroleum resin was pyrolysis gasoline and that the heart-cut used in the resin plant was obtained by a separate fractionation process after removal of benzene and toluene. The stream used for petroleum resin was not treated as an incidental or inevitable concomitant of the manufacture of the specified products in the notification. The captive-use exemption for Chapter 27 goods also did not assist the assessee because the material used for resin manufacture was not established to be an exempt by-product in the manner claimed.

Conclusion: The claim for full exemption on the disputed stream was rejected, and the issue was decided against the assessee.

Issue (ii): Whether the demand was barred by limitation.

Analysis: The assessee had described the input for petroleum resin as pyrolysis gasoline in its filings, while the material used for the resin plant was found to be the separated C8/C9 cut. The manner in which the process and input were disclosed left vagueness and misdescription, supporting invocation of the extended limitation period under the proviso to Section 11A.

Conclusion: The demand was held not to be barred by limitation, and this issue was decided against the assessee.

Issue (iii): Whether the entire duty demand could be sustained.

Analysis: Although the exemption was denied on the disputed diversion, the duty had been computed on the entire quantity sent to the resin plant. The reasoning accepted that duty should be confined to the balance residue actually diverted for extraction of the C8/C9 cut, after excluding the portions used for the exempted specified products. The adjudicating authority was therefore required to recompute the demand on the correct basis.

Conclusion: The entire duty demand was not sustained, and the matter was sent back for fresh quantification, in part favouring the assessee.

Issue (iv): Whether the penalty was justified.

Analysis: The finding of misdeclaration and misuse of the exemption notifications justified the imposition of penalty, but the reduction in the sustainable duty and the overall facts warranted moderation of the quantum.

Conclusion: The penalty was upheld in principle but reduced substantially.

Final Conclusion: The assessee failed on the core exemption and limitation questions, but succeeded on the quantification of duty and on obtaining a substantial reduction in penalty, resulting in a partial allowance of the appeal.

Ratio Decidendi: Where a concession for raw naphtha is confined to specified end-products, a separately fractionated stream used for an unlisted product does not qualify for the concession, and vague or misleading disclosure of the input and process can justify the extended limitation period.
