Manufacturing loss of escaped gases treated as waste under Rule 57D, with concurrent factual findings upheld in favour of the assessee.

Escaped gases lost during the process of compressing and filling oxygen and argon cylinders were treated as waste or loss of inputs arising in the course of manufacture under Rule 57D of the Central Excise Rules, 1944. The assessee's activity was regarded as manufacture, and the concurrent findings of the Commissioner (Appeals) and the Tribunal that the escaped gases constituted waste were accepted. As no infirmity was found in that reasoning, no substantial question of law arose for interference, and the claim was sustained in favour of the assessee.

Issues: Whether gases escaped during the process of filling cylinders could be treated as waste, refuse, by-product, or loss of inputs within Rule 57D of the Central Excise Rules, 1944.

Analysis: The assessee's activity of compressing and filling oxygen and argon gases in cylinders was treated as manufacture. The escaped gases were found to have been lost during the manufacturing process itself, and both the Commissioner (Appeals) and the Tribunal had concurrently held that such escaped gases were in the nature of waste. In the absence of any infirmity in that reasoning, no substantial question of law arose for interference.

Conclusion: The escaped gases were covered by Rule 57D as waste or loss during manufacture, and the finding was sustained in favour of the assessee.

Ratio Decidendi: Loss of inputs occurring during the manufacturing process, including escapement of gases, can be treated as waste within Rule 57D where it arises in the course of manufacture and is supported by concurrent factual findings.
