M/S. Tata Chemicals Ltd vs Collector Of Central Excise

The Supreme Court addressed the issue of excise duty on packing materials under Section 4 of the Central Excise Act, 1944, specifically regarding the exclusion of costs for durable packing materials supplied by buyers. The Court held that if packing materials are provided by the purchaser, excise duty cannot be levied on them, thereby clarifying the legal principle that the nature of the packing material's supply affects duty liability. The judgment overturned the tribunal's previous stance, leading to a favorable outcome for the appellant regarding the assessment of excise duty.
