Rubber goods classification under Tariff Heading 40.16 defeats machinery-part treatment and collapses duty and penalty consequences.

Articles made from unhardened vulcanised rubber were classifiable under Tariff Heading 40.16 and not under machinery-part headings in Chapter 84, because the relevant tariff scheme and Section Note excluded such goods from Section XVI even when used in machinery. Applying the settled classification principle, the appellants' classification was accepted and the departmental view was rejected. Once the classification failed, allegations of suppression or misdeclaration also could not be sustained, so the differential duty demand and penalties were set aside.

Issues: Whether articles manufactured from unhardened vulcanised rubber were classifiable under Chapter 84 as machinery parts or under Tariff Heading 40.16 as rubber articles, and whether any misdeclaration, suppression, differential duty, or penalty was sustainable.

Analysis: The goods were manufactured from unhardened vulcanised rubber. The governing tariff framework and the relevant Section Note excluded articles of that kind from Section XVI even if they were used in machinery. Applying the binding classification principle already settled by precedent, the goods were held to fall under Tariff Heading 40.16 as claimed by the appellants, and not under the machinery-part headings adopted in the impugned order. Once the classification adopted by the department failed, the foundation for alleging suppression or misdeclaration also disappeared, and the demand of differential duty as well as the penalties could not survive.

Conclusion: The classification adopted by the appellants was correct, there was no suppression or misdeclaration, and the demand of duty and all penalties were set aside in favour of the assessee.

Final Conclusion: The appeal succeeded and the impugned order was reversed in full, resulting in complete relief to the appellants.

Ratio Decidendi: Articles made from unhardened vulcanised rubber are classifiable under the rubber tariff heading and are not brought into the machinery section merely because they are used as parts of machinery; absent a sustainable classification dispute, suppression and penal liability cannot be fastened.
