Classification of lamp ignitors under Heading 85.39 confirms parts of sodium vapour lamps can share the same tariff entry.

Electronic ignitors used to fire high-pressure sodium vapour lamps were treated as integral functional parts of those lamps and classified under Heading 85.39, sub-heading 8539.00, rather than as a ballast or a residuary item. Because sodium vapour lamps themselves fell within that heading, their parts were also held to fall under the same tariff entry. The related exemption for parts of goods classified under that heading was accordingly applied, and the exemption treatment accepted for the assessee was maintained.

Issues: Whether electronic ignitors for sodium vapour lamps were classifiable under Heading 85.39 of the Central Excise Tariff, and whether the benefit of exemption for parts of goods so classified was available.

Analysis: The product was described as a device used to fire high-pressure sodium vapour lamps and to supply the strong current pulse needed for illumination. The competing headings were examined, and the goods were held not to be a ballast or a residuary item. Since sodium vapour lamps themselves fell under Heading 85.39, their parts were also appropriately treated under the same heading rather than under the residual entry. The exemption aspect was also considered, and the goods classifiable under sub-heading 85.39 were found to be covered by the relevant exemption notification applicable to parts of such goods.

Conclusion: The electronic ignitors were correctly classifiable under Heading 85.39, sub-heading 8539.00, and the exemption position accepted by the Assistant Collector was upheld in favour of the assessee.

Final Conclusion: The appeal succeeded, the order-in-appeal was set aside, and the classification adopted by the Assistant Collector was restored along with the related exemption treatment.

Ratio Decidendi: Where a product is an integral functional part used for operating a lamp classifiable under a particular tariff heading, it may itself be classified under that heading rather than under a residuary entry, and the corresponding exemption for parts will apply if the notification so provides.
