Tungsten halogen lamps were treated as a distinct product, denying exemption under the gas filled lamps classification.

Tungsten halogen lamps were held to fall outside the exempted category of gas filled bulbs or lamps because Notification No. 67/83-C.E. required classification and nomenclature to follow Indian Standard specifications, and those specifications treated tungsten halogen lamps as a distinct product. The lamps were therefore covered by Sl. No. 10 and attracted duty at the corresponding rate. The limitation objection was not decided by the referring Bench and was left open for consideration by the regular Bench.

Issues: Whether tungsten halogen lamps were classifiable as gas filled bulbs under Sl. Nos. 4 and 5 of Notification No. 67/83-C.E. or as bulbs and lamps under Sl. No. 10, and whether the demand was barred by limitation.

Analysis: The notification directed that classification and nomenclature of bulbs or lamps were to be governed by Indian Standard specifications. Under those specifications, tungsten halogen lamps were treated as distinct from gas filled lamps. Their composition, including the presence of halogen, gave them a separate identity in the technical classification, and they could not be brought within the expression gas filled lamps for the purpose of the exemption notification. The limitation objection was not examined by the referring Bench and was left open for consideration by the regular Bench.

Conclusion: Tungsten halogen lamps were not eligible for classification under Sl. Nos. 4 and 5 and were correctly covered by Sl. No. 10, attracting duty at the corresponding rate. The classification issue was answered against the assessee and in favour of the Revenue.

Final Conclusion: The reference was answered in favour of the Revenue on the classification question, while the limitation plea remained open for the original Bench.

Ratio Decidendi: Where an exemption notification makes classification dependent on Indian Standard specifications, a product separately recognised under those specifications cannot be treated as falling within a broader exempted category merely because it contains one of the ingredients of that category.
