Marketability and suppression determine excise duty on captively used intermediate products; demand failed on both counts.

Captively consumed coating solution used in the manufacture of fluorescent tubes was held not dutiable because the Department failed to prove that it was marketable as a distinct commodity; marketability remains an essential ingredient for excise duty, even for intermediate products. The Tribunal also held that the extended limitation period could not be invoked, as the assessee had disclosed the manufacture and use of the product and mere non-entry in the classification list did not amount to suppression of facts with intent to evade duty. The demand was therefore unsustainable on both merits and limitation.

Issues: (i) Whether the coating solution used captively in the manufacture of fluorescent tubes was an excisable product liable to duty under the tariff entries in force during the relevant period. (ii) Whether the demand raised beyond the normal limitation period was barred by time.

Issue (i): Whether the coating solution used captively in the manufacture of fluorescent tubes was an excisable product liable to duty under the tariff entries in force during the relevant period.

Analysis: The question of excisability turned on whether the intermediate product was marketable and known to the market as a distinct commodity. The Department relied mainly on the Chemical Examiner's report describing the sample as a white liquid having characteristics of cellulose lacquer and capable of giving a track-free adherent coating. The assessee disputed marketability and relied on evidence to show that the product was a transient intermediate used only in the manufacturing process and had no shelf life. The Tribunal held that marketability is an essential ingredient for levy of excise duty, including in respect of captively consumed intermediate products, and that the burden lies on the Department to establish by evidence that the article is capable of being marketed as a distinct commodity. As no satisfactory evidence of marketability was produced, the classification and duty demand could not be sustained.

Conclusion: The coating solution was not proved to be marketable excisable goods, and the duty liability on that basis was not sustainable in favour of the assessee.

Issue (ii): Whether the demand raised beyond the normal limitation period was barred by time.

Analysis: Invocation of the extended period under the proviso to section 11A required proof of suppression of facts or similar culpable conduct with intent to evade duty. The record showed that the assessee had informed the Department about the manufacture and use of the coating solution and had replied to departmental queries, while the Department was itself uncertain about the excisability of the product. In these circumstances, mere non-entry in the classification list did not amount to suppression of facts justifying the extended limitation period. The demand therefore could not survive beyond the normal period of limitation.

Conclusion: The demand was time barred and the extended period was wrongly invoked, in favour of the assessee.

Final Conclusion: The impugned order was set aside because the Department failed to establish marketability and also failed to justify invocation of the extended period of limitation.

Ratio Decidendi: For captively consumed intermediate goods, excise duty can be sustained only if the Department proves marketability as a distinct commodity, and the extended limitation period can be invoked only on proof of suppression or analogous culpable conduct with intent to evade duty.
