Excisability of intermediate goods and limitation in excise duty demand: transmission assemblies were dutiable, but extended limitation was unavailable.

An intermediate product is dutiable when it emerges during manufacture as a distinct and commercially known commodity; on that principle, transmission assemblies arising in tractor production were held excisable even though they were captively consumed. However, the extended limitation period could not be invoked because the manufacturing process and sub-assemblies had been disclosed to the department and there was no evidence of fraud, wilful misstatement, or suppression of facts. Duty liability was therefore upheld on merits, but the demand itself was held time-barred.

Issues: (i) Whether transmission assemblies arising in the course of manufacture of tractors were excisable goods; (ii) whether the extended period of limitation could be invoked for the duty demand.

Issue (i): Whether transmission assemblies arising in the course of manufacture of tractors were excisable goods.

Analysis: The Tribunal applied the settled position that an intermediate product is dutiable if it comes into existence as a distinct and commercially known product. It relied on the governing Supreme Court decision on transmission assemblies in tractor manufacture and held that the assemblies emerged during the manufacturing process, had commercial identity, and were not rendered non-dutiable merely because they were captively consumed and not sold.

Conclusion: Yes. The transmission assemblies were held to be excisable intermediate goods and duty was upheld on merits.

Issue (ii): Whether the extended period of limitation could be invoked for the duty demand.

Analysis: The Tribunal found that the manufacturing process and identifiable sub-assemblies had been disclosed to the department and there was no material to show fraud, wilful misstatement, or suppression of facts. In the absence of contumacious conduct, the extended limitation period could not be applied to the notice issued beyond the normal period.

Conclusion: No. The demand was held to be time-barred and the extended period was not available to the Revenue.

Final Conclusion: The Tribunal accepted the duty liability on merits but rejected the demand as barred by limitation, resulting in partial success for the Revenue only on the question of dutiability.

Ratio Decidendi: An intermediate product is excisable if it emerges as a distinct commercially known commodity, but the extended limitation period under excise law cannot be invoked absent fraud, wilful misstatement, or suppression of facts.
