Residuary tariff classification and no retrospective exemption apply to zinc calots and related excise notification relief.

A distinct marketable zinc calot, known in trade by that name and not as a zinc circle, was treated as outside Item 26B(2) because that entry covered only specifically named zinc manufactures; it was therefore assessable under the residuary Item 68. The exemption under Notification No. 118/75-C.E. was held to operate only from its date of issue, as exemption notifications do not apply retrospectively unless express authority or explicit retrospective language is provided. The result was classification under the residuary entry and denial of retrospective exemption.

Issues: (i) Whether zinc calots were classifiable under Item 26B(2) of the Central Excise Tariff or only under the residuary Item 68. (ii) Whether Notification No. 118/75-C.E., dated 30-4-1975, exempting Item 68 goods used within the factory or in another factory of the same manufacturer, could be given retrospective effect from 1-3-1975.

Issue (i): Whether zinc calots were classifiable under Item 26B(2) of the Central Excise Tariff or only under the residuary Item 68.

Analysis: Zinc calots were found to be known in the market as zinc calots and not as zinc circles. Item 26B(2) covered only specifically named zinc manufactures, and zinc calots were not included in that category. The product was a distinct, marketable article separate from the rough rolled zinc sheets from which it was punched. Since it was not specifically covered by Item 26B, it fell within the residuary Item 68.

Conclusion: Zinc calots were not classifiable under Item 26B(2) and were correctly assessable only under Item 68, in favour of Revenue.

Issue (ii): Whether Notification No. 118/75-C.E., dated 30-4-1975, could be given retrospective effect from 1-3-1975.

Analysis: Exemption notifications operate from the date of issue unless the notification itself expressly provides retrospective effect. No retrospective operation was provided, and the Central Government was held to have no power to grant such exemption retrospectively in the absence of express authorization.

Conclusion: The notification could not be applied retrospectively, in favour of Revenue.

Final Conclusion: The classification under the residuary tariff entry was upheld and retrospective exemption was denied, so the appeal failed in entirety.

Ratio Decidendi: A distinct marketable product not specifically named in a tariff entry is assessable under the residuary entry, and an exemption notification takes effect only from its date of issue unless retrospective operation is expressly provided.
