ANFO manufacture and excisability upheld, but the duty demand was limited to the normal limitation period.

Mixing ammonium nitrate and fuel oil to produce ANFO was treated as manufacture because it created a distinct commodity with a separate name, character and use. ANFO was held to be excisable goods despite captive consumption, as marketability and a separate identity were sufficient for central excise levy. It was also treated as a prepared explosive falling under Chapter 36, with technical and trade usage supporting that classification. On limitation, the extended period was not available because the record did not establish fraud, wilful misstatement, suppression of facts, or intent to evade duty; the demand was therefore restricted to the normal six-month period.

Issues: (i) whether the mixing of ammonium nitrate and fuel oil to produce ANFO amounted to manufacture; (ii) whether ANFO was goods for the purpose of central excise levy, including on captive consumption; (iii) whether ANFO was a prepared explosive falling under Chapter 36 and within the scope of the Explosives Act; and (iv) whether the demand beyond six months was barred for want of ingredients to invoke the extended period.

Issue (i): whether the mixing of ammonium nitrate and fuel oil to produce ANFO amounted to manufacture.

Analysis: The product emerged from mixing two inputs into a distinct commodity known in trade as ANFO, used specifically for blasting. The process was not merely a physical aggregation of ingredients but resulted in a new product having a distinctive name, character and use. The principle applied was that manufacture requires transformation into a different article with a distinct identity.

Conclusion: The mixing amounted to manufacture.

Issue (ii): whether ANFO was goods for the purpose of central excise levy, including on captive consumption.

Analysis: ANFO was manufactured at a place different from its point of use, had a separate identity in technical literature, and was capable of being marketed. Actual sale was not essential where the article was capable of being brought to market. Captive use did not detract from excisability once manufacture and marketability were established.

Conclusion: ANFO was goods and was liable to excise duty notwithstanding captive consumption.

Issue (iii): whether ANFO was a prepared explosive falling under Chapter 36 and within the scope of the Explosives Act.

Analysis: Technical literature described ANFO as a high explosive, and the licensing requirement issued by the explosives authority showed that it was treated as an explosive mixture. In the absence of a tariff definition of prepared explosives, technical dictionaries and internationally accepted usage were relied upon to understand the tariff entry. The item was held to answer the description of prepared explosives.

Conclusion: ANFO was a prepared explosive and fell within Chapter 36.

Issue (iv): whether the demand beyond six months was barred for want of ingredients to invoke the extended period.

Analysis: The record did not contain a finding that there was fraud, wilful misstatement, suppression of facts, or contravention with intent to evade duty. Mere non-disclosure or non-compliance, without a recorded finding on intent to evade, was insufficient to attract the extended limitation period. The demand could therefore survive only within the normal limitation period.

Conclusion: The extended period was not invocable and the demand was confined to six months from the date of receipt of the show cause notice.

Final Conclusion: The levy of duty on ANFO was upheld, but the demand was curtailed to the normal limitation period, resulting in only partial relief to the assessee.

Ratio Decidendi: A product obtained by mixing ingredients is manufacture when it yields a distinct commodity with a separate name, character and use, and the extended period of limitation can be invoked only when suppression or other statutory ingredients are found with intent to evade duty.
