Intermediate product doctrine bars excise duty where audio cassette housing never emerged as a separate commodity before final manufacture.

No excise duty could be levied on Audio Cassette Housing because it did not come into existence as a separate, marketable intermediate product before the final audio cassette tape emerged. The Tribunal applied its earlier view on the same manufacturing process and found that the housing and the tape came into existence simultaneously, with no prior removal of a distinct captive-use product. The interpretative rule for incomplete or unfinished goods was rejected on the facts, since the alleged intermediate stage had not emerged as an independent commodity. The duty demand on the housing was therefore unsustainable.

Issues: Whether Audio Cassette Housing came into existence as a dutiable excisable product before the manufacture of audio cassette tape, and whether duty could be demanded on that basis.

Analysis: The Tribunal followed its earlier decision on the same manufacturing process and held that no separate product described as Audio Cassette Housing came into existence prior to the emergence of the final audio cassette tape. On the facts, the housing and the tape came into existence simultaneously, so there was no prior removal of a distinct intermediate product for captive use. The argument based on the interpretative rule for incomplete or unfinished goods was rejected because the goods in question had not emerged as a separate commodity in advance of the final product.

Conclusion: The duty demand on Audio Cassette Housing was unsustainable and the issue was decided in favour of the assessee.

Ratio Decidendi: Where an alleged intermediate product does not come into existence as a separate marketable commodity before the final product emerges, no excise duty can be demanded on that alleged intermediate stage of manufacture.
