Principal design governs chassis classification, and extended limitation fails without proved suppression or clandestine clearance.

Classification of chassis and cowl depended on principal design, not on later purchaser use. The evidence showed a common chassis design capable of both goods and passenger applications, and technical material did not establish that progressive springs and shock absorbers made it principally designed for passenger transport; the residuary interpretative rule was therefore applied and classification under sub-heading 8706.40 was upheld, while the rival claim under sub-heading 8706.30 failed. On limitation, clearances were reflected in classification lists and invoices, enquiries had been made, and the record did not prove deliberate suppression, clandestine clearance, or intent to evade duty; the extended period was therefore not available.

Issues: (i) Whether the chassis and cowl were classifiable under sub-heading 8706.30 as goods principally designed for transport of persons or under sub-heading 8706.40 as chassis for transport of goods. (ii) Whether the demand was sustainable by invoking extended limitation and allegations of suppression and clandestine clearance.

Issue (i): Whether the chassis and cowl were classifiable under sub-heading 8706.30 as goods principally designed for transport of persons or under sub-heading 8706.40 as chassis for transport of goods.

Analysis: The tariff description required classification to turn on the principal design of the chassis, not merely on actual later use by purchasers. The evidence showed that the same basic chassis design was used for both goods and passenger applications, that progressive springs and shock absorbers were not conclusive indicators of passenger design, and that technical material and expert opinions supported the view that such features could also be used in commercial vehicles. The Court also noted that a substantial portion of the clearances had been used for goods transport. Since the goods were not shown to be principally designed for passenger transport, and both competing headings otherwise merited consideration, the residuary interpretative rule was applied.

Conclusion: The classification under sub-heading 8706.40 was upheld and the Revenue's plea for classification under sub-heading 8706.30 was rejected.

Issue (ii): Whether the demand was sustainable by invoking extended limitation and allegations of suppression and clandestine clearance.

Analysis: The clearances were made under classification lists and invoices, the department had conducted enquiries, and the material on record did not establish any deliberate suppression with intent to evade duty. The alleged end-use knowledge did not alter the classification result, and the record did not justify treating the matter as clandestine removal for limitation purposes. In these circumstances, the conditions for invoking the extended period were not satisfied.

Conclusion: The demand could not be sustained on the basis of suppression or clandestine clearance, and the extended period was not invocable.

Final Conclusion: The appeals were disposed of in favour of the assessee, with the Revenue's challenge failing on merits and on limitation.

Ratio Decidendi: Where a tariff entry turns on principal design, classification cannot be determined merely by actual end use or isolated admissions if the evidence shows that the goods are capable of multiple uses and are not shown to be principally designed for the rival entry; in such a case, the residuary interpretative rule may govern and limitation cannot be extended absent proved suppression with intent to evade duty.
