Diesel coalescer classification as a complete machine upheld where a replaceable cartridge was only an operating component.

A fabricated steel vessel used to purify diesel by removing moisture under high pressure was held to retain the essential character of a complete diesel coalescer. The presence of an internally fitted cartridge with filter elements, separately imported and functioning as a replaceable operating component, did not reduce the item to a mere part. The Tribunal therefore treated the goods as a machine with an independent function and upheld classification under sub-heading 8479.10 rather than as a part under sub-heading 8479.90.

Issues: Whether the goods fabricated as a diesel coalescer were classifiable as a complete machine under sub-heading 8479.10 of the Central Excise Tariff Act, 1985 or only as a part under sub-heading 8479.90.

Analysis: The item fabricated by the respondent was a steel vessel designed to purify diesel by removing moisture content under high pressure. A cartridge containing filter elements was fitted inside the vessel, but the cartridge was separately imported and was only an operating component. The essential character of the fabricated item remained that of a diesel coalescer, and the need for a replaceable cartridge did not convert the vessel into a mere part. On this basis, the Tribunal agreed with the view that the goods were complete machines with an independent function.

Conclusion: The diesel coalescer was correctly treated as a machine and not merely as a part, and the classification under sub-heading 8479.10 was upheld in favour of the assessee.

Ratio Decidendi: Where a fabricated item is capable of performing its designated function as a complete machine with an internally fitted replaceable component, it is classifiable as a machine and not as a part merely because such component is required for operation.
