Integrated mining and concentrate production justified exemption for blasting explosives used in ore extraction.

Explosives used in copper mines for blasting and ore extraction were treated by the majority as goods used in the manufacture of copper concentrates for purposes of exemption under Notification No. 191/87 as amended by Notification No. 63/91. The majority reasoned that mining and concentration formed an integrated process, so denying the benefit would defeat the notification's purpose and render it ineffective. The contrary view treated mining and manufacture of concentrates as distinct activities and held that explosives used only for extraction were outside the exemption. On the majority view, the explosives qualified for exemption and the Revenue's appeal failed.

Issues: Whether explosives used in copper mines for blasting and extraction of ore are entitled to exemption under Notification No. 191/87 as amended by Notification No. 63/91 on the footing that they are goods used in the manufacture of copper concentrates.

Analysis: The majority held that the exemption covered goods falling under Chapter 36 when used in the manufacture of copper concentrates, and that the mining operation and the subsequent production of concentrates formed an integrated process. On that view, explosives used for blasting the ore-bearing mines were the only Chapter 36 goods employed in the chain leading to concentrates, and denying the benefit would make the notification unworkable and defeat its purpose. The contrary view treated mining and concentration as distinct activities and relied on earlier Tribunal rulings holding that explosives used for extraction of ore were not used in manufacture. The majority preferred the construction that gave effect to the notification's true import and avoided a nugatory interpretation.

Conclusion: The explosives were held eligible for exemption under the notification, and the Revenue's appeal was rejected.

Dissenting Opinion: The Member (Judicial) held that mining and manufacture of concentrates are distinct processes, that explosives used only for extraction of ore are not used in the manufacture of concentrates, and that the exemption was therefore not available.

Ratio Decidendi: Where mining of ore and production of concentrates form an integrated process, goods used in blasting and extraction at the mining stage may be treated as goods used in the manufacture of the concentrates for the purpose of a notification granting exemption to goods used in such manufacture.
