Unassembled boiler components were treated as the complete machine where essential parts constituted the finished boiler.

Boiler components cleared in an unassembled state were classified by reference to their essential character and whether they formed an incomplete machine with the features of the complete boiler. Applying the technical distinction between essential components and auxiliary accessories, and the HSN explanatory note on unassembled machines, the Supreme Court treated the essential boiler parts as the machine itself rather than separate parts. The resulting classification under sub-heading 8402.10 was upheld, and the competing classification under sub-heading 8402.90 was rejected.

Issues: Whether the essential components and parts of a boiler cleared in an unassembled state were classifiable under sub-heading 8402.10 as goods other than parts, or under sub-heading 8402.90 as parts.

Analysis: The classification had to be determined by the nature of the goods and the effect of transport in an unassembled condition. The authorities relied on the technical opinion distinguishing essential boiler components from auxiliary accessories, and on the HSN explanatory note that machines transported unassembled are to be classified as the machine itself when they constitute an incomplete machine having the features of the complete machine. On that basis, components essential to the boiler were treated as forming the complete machine and not as separate parts.

Conclusion: The components essential for putting the boiler into operation were correctly classified under sub-heading 8402.10 and not under sub-heading 8402.90. The classification adopted by the lower authorities was upheld and the appeal failed.

Ratio Decidendi: Where goods are cleared in an unassembled state but the components are essential to constitute the complete machine, they are classifiable as the machine itself and not as separate parts.
