Primary function test governs classification of a bogie centre pivot bolt; suppression of facts can justify extended limitation.

Classification of a Bogie Centre Pivot Bolt turns on its primary function, not merely its description as a bolt or threaded form. If the item serves as part of a railway wagon and permits swivelling movement rather than rigid fastening, it may fall within the wagon-component entry; the record was considered insufficient, so fresh determination was required. For extended limitation, the ordinary six-month period may be extended to five years where non-levy arises from suppression of facts or similar contravention with intent to evade duty. On the stated facts, non-disclosure of manufacture supported application of the extended period.

Issues: (i) whether the product described as Bogie Centre Pivot Bolt was classifiable as a fastener under Tariff Item 52 or as a component part of a railway wagon under Tariff Item 68; (ii) whether the demand for duty for the extended period of five years was sustainable on the ground of suppression of facts.

Issue (i): whether the product described as Bogie Centre Pivot Bolt was classifiable as a fastener under Tariff Item 52 or as a component part of a railway wagon under Tariff Item 68.

Analysis: The classification depended on the primary function of the item and not merely on its description as a bolt or its threaded form. The record before the authority below was found insufficient on the technical aspect, and the material relied upon by the appellant also required proper verification. If the pivot bolt did not rigidly fasten the bogie and underframe but left space for swivelling movement, its primary role would be as a component of the wagon rather than as a mere fastener. Further investigation and fresh evidence were therefore necessary.

Conclusion: The issue was remanded to the adjudicating authority for fresh determination of the correct classification.

Issue (ii): whether the demand for duty for the extended period of five years was sustainable on the ground of suppression of facts.

Analysis: Section 11A provided the ordinary six-month period and permitted extension to five years where non-levy arose from fraud, wilful mis-statement, suppression of facts, or similar contravention with intent to evade duty. The appellant had not disclosed manufacture of the goods to the excise authorities and had not shown that the department had knowledge of such manufacture. On that basis, non-levy was attributable to suppression of facts.

Conclusion: The extended period of five years was held applicable and the plea of limitation was rejected.

Final Conclusion: The appeal succeeded only to the extent that the classification dispute was sent back for reconsideration, while the challenge to the extended limitation period failed.

Ratio Decidendi: Classification depends on the primary function of the goods, and the extended period under limitation provisions applies where non-levy results from suppression of facts by the assessee.
