Functional tariff classification and suppression-based limitation: specific entry prevails, but extended demand needs proof of culpable concealment.

Electrical control panel assemblies for hoists were treated as motor starters because their essential function was to control the start and stop operations of the electric motor, even though they also performed braking, inching and limit-switch functions; the specific tariff entry prevailed over the residuary entry. On limitation, the extended period could not be invoked without proof of fraud, collusion, wilful misstatement or suppression of facts, especially where classification lists had been filed and approved and the department could have examined the goods earlier. The classification issue favoured the department, but the duty demand was confined to the period not barred by limitation, giving partial relief to the assessee.

Issues: (i) Whether the electrical control panel assembly manufactured for hoists was classifiable as a motor starter under TI 30B or as a residuary item under TI 68; (ii) Whether the extended period of limitation could be invoked for the duty demand on the ground of suppression of facts.

Issue (i): Whether the electrical control panel assembly manufactured for hoists was classifiable as a motor starter under TI 30B or as a residuary item under TI 68.

Analysis: The decisive test was the function performed by the goods. The control panel assembly admittedly controlled the start and stop operations of the electric motor fitted to the hoist and worked on the principle of a motor starter, though it also performed additional functions such as braking, inching and limit-switch control. Since the tariff description was clear, trade meaning or commercial nomenclature could not prevail over the statutory entry. The residuary entry was therefore unavailable where the specific entry covered the goods.

Conclusion: The control panel assembly was correctly classifiable under TI 30B and not under TI 68, against the assessee.

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

Analysis: The record showed that the classification lists had been filed and approved from time to time, and there was no material to show that the assessee had withheld information with intent to evade duty. The department could have examined the nature and function of the goods at the time of approval. In the absence of established fraud, collusion, wilful misstatement or suppression, the extended limitation could not be applied for the earlier period.

Conclusion: The extended period was not available, and the demand was restricted to the later period only, in favour of the assessee.

Final Conclusion: The classification of the control panel assembly under TI 30B was upheld, but the duty demand was confined to the period not barred by limitation, resulting in partial relief to the assessee.

Ratio Decidendi: Where a tariff entry clearly covers goods by their function, the specific entry prevails over the residuary entry; and the extended period of limitation requires proof of suppression or other culpable conduct, which cannot be presumed merely because the department had approved earlier classifications.
