Commercial understanding of tariff goods prevails; ambiguity in classification is resolved in favour of the assessee for exemption.

Cycle grade steel balls were considered under tariff classification principles by reference to their commercial understanding, not a purely dictionary meaning. The text states that the goods were not polished steel balls in the sense required for ball-bearing parts under Heading 84.82, and that ambiguity in the Chapter Note on diameter tolerances had to be resolved in favour of the assessee. On that basis, the goods were treated as cycle-related parts rather than ball-bearing parts, and the exemption under Notification No. 234/82 became applicable. The stated effect was that the Revenue's challenge failed and the assessee retained the exemption with consequential relief.

Issues: Whether cycle grade steel balls manufactured by the assessee were classifiable as parts of ball bearings under Tariff Heading 84.82 or as cycle parts under the relevant tariff headings, and whether they were entitled to the benefit of exemption under Notification No. 234/82.

Analysis: The classification turned on the meaning of polished steel balls in Chapter Note 6 to Chapter 84 and on the commercial understanding of the goods. The reasoning adopted the trade and industry sense of the expression rather than a purely dictionary meaning, and held that the steel balls in question were not polished in the sense relevant to ball-bearing parts. The note was found to be ambiguous on the diameter tolerances, and where two views were possible the benefit of ambiguity was given to the assessee. On that basis, the goods were held not to satisfy the criteria for Heading 84.82 and were treated as falling under the cycle-related headings, making the exemption notification applicable.

Conclusion: The steel balls were not classifiable under Tariff Heading 84.82 and were entitled to exemption under Notification No. 234/82, in favour of the assessee.

Final Conclusion: The Revenue's challenge to the exemption failed, and the assessee retained the benefit of the notification with consequential relief.

Ratio Decidendi: Where a tariff provision is ambiguous, the classification must follow the commercial understanding of the goods and the ambiguity must be resolved in favour of the assessee.
