Trade and common parlance test upheld for tariff classification of a self-locking nut, but excise demand was quashed.

Tariff classification of a nyloc self-locking nut was determined by trade and common parlance, and by viewing the article as a whole; because it remained primarily a metal nut used as a fastener, it was correctly classified under Tariff Item 52 as an improved type of nut. The separate demand raised by letter dated 21 April 1978 was held unenforceable because it was referable to Rule 10 of the Central Excise Rules yet issued without the required procedure and beyond jurisdiction, and its correctness was not otherwise established. The classification was upheld, but the demand notice was quashed and refund relief was refused.

Issues: (i) Whether the petitioners' product, nyloc self-locking nut, was correctly classified under Tariff Item 52 as nuts and fasteners; (ii) whether the demand made by the letter dated 21 April 1978 was legal and enforceable.

Issue (i): Whether the petitioners' product, nyloc self-locking nut, was correctly classified under Tariff Item 52 as nuts and fasteners.

Analysis: Classification of an excisable article depends upon the sense in which it is understood in trade and common parlance. The commodity has to be viewed as a whole and not by isolating one feature such as locking or sealing. The evidence, literature issued by the manufacturer, certificates from dealers and users, and the materials relied upon by the department showed that the product was a metal nut used primarily as a fastener, though it had additional locking advantages. Trade notices issued by collectorates and the views expressed in other matters did not displace the plain scope of the tariff entry. The product was therefore an improved or special type of nut, but still a nut within the tariff description.

Conclusion: The product was correctly held to fall within Tariff Item 52, against the assessee.

Issue (ii): Whether the demand made by the letter dated 21 April 1978 was legal and enforceable.

Analysis: The demand was referable to Rule 10 of the Central Excise Rules. A direct demand without the procedure required by the rule, and without a proper show-cause process where required, was beyond jurisdiction. The amount demanded was also not shown to be correct, and the demand could not be sustained merely as an execution step following the classification decision.

Conclusion: The demand letter dated 21 April 1978 was illegal, jurisdiction, and unenforceable.

Final Conclusion: The classification of the product was upheld, but the impugned demand notice was quashed; the petition succeeded only to that limited extent, with refund relief declined.

Ratio Decidendi: In tariff classification, the product must be identified according to its popular or trade understanding and its predominant character as a whole, and a demand under the excise rules cannot be enforced if issued without jurisdiction or outside the prescribed procedural framework.
