Classification of sodium orthovanadate under Chapter 28.41 upheld; extended duty period and retrospective penalty were rejected.

Vanadium sludge consisting substantially of sodium orthovanadate was treated as an oxometallic compound and classified under Chapter Heading 28.41, because Chapter 26.20 was inapplicable to a product that was not an ash or residue of the kind covered by that heading. The extended limitation period for differential duty could not be invoked where the classification list had been disclosed to the Department and no suppression was shown; duty was confined to the normal period preceding the notice. Penalty under Section 11AC could not be sustained for clearances made before that provision came into force, and the interest direction in the impugned order also could not stand in its imposed form.

Issues: (i) Whether Vanadium Sludge, consisting substantially of Sodium Orthovanadate, was classifiable under Chapter Heading 26.20 or under Chapter Heading 28.41; (ii) Whether the demand for differential duty for the earlier period was barred by limitation and the extended period under the proviso to Section 11A(1) could be invoked; (iii) Whether penalty under Section 11AC and interest under Section 11AB could be sustained.

Issue (i): Whether Vanadium Sludge, consisting substantially of Sodium Orthovanadate, was classifiable under Chapter Heading 26.20 or under Chapter Heading 28.41

Analysis: The material was found to be Sodium Orthovanadate with moisture and a small impurity of Sodium Hydroxide. It was treated as an oxometallic compound and, therefore, a salt of an oxometallic acid. Heading 26.20 was held inapplicable because the product was not ash or residue of the kind contemplated by the chapter note. Chapter 28, read with its notes, governed salts of oxometallic acids, and the relevant notes did not require a different context for the goods.

Conclusion: The goods were held classifiable under Chapter Heading 28.41, against the assessee.

Issue (ii): Whether the demand for differential duty for the earlier period was barred by limitation and the extended period under the proviso to Section 11A(1) could be invoked

Analysis: The classification list had been filed before the Department and nothing was concealed. In those circumstances, the Department could not invoke the extended period after remaining inactive for more than three years. The earlier notice was held to be time-barred beyond the normal period, and duty could be confined only to the period falling within six months immediately preceding the notice dated 22-3-1991.

Conclusion: The extended period was held not invocable, and the demand was confined to the normal limitation period, in favour of the assessee.

Issue (iii): Whether penalty under Section 11AC and interest under Section 11AB could be sustained

Analysis: Section 11AC was stated to have come into force only on 28-9-1996, whereas the disputed clearances related to an earlier period ending in February 1991. On that reasoning, penalty under Section 11AC could not be imposed for the past clearances. The order of penalty was accordingly set aside. The direction regarding interest also could not survive in the form imposed in the impugned order.

Conclusion: Penalty under Section 11AC was set aside, in favour of the assessee.

Final Conclusion: The classification under Heading 28.41 was upheld, but the duty demand was restricted to the legally recoverable period and the penalty was removed, with the matter remitted for recomputation of duty for the surviving period after hearing the assessee.

Ratio Decidendi: For classification, the terms of the heading and the relevant chapter notes prevail over the interpretative rules; for duty demand, the extended period cannot be invoked absent suppression or concealment, and a penalty provision cannot be applied retrospectively to past clearances.
