Machine-specific component classification supports customs exemption for an imported lubricating unit used in a surface grinder.

A machine-specific lubricating unit designed solely for fitment in an ELB surface grinder was treated as a component of the machine tool, not a general spare part, because it was essential to lubrication and hydraulic control and its function was integrally linked to the grinder. On that basis, it fell under Heading 8466.93 rather than Heading 84.79.89. The classification as a machine-tool component also brought the item within the scope of Notification No. 156/86-Cus., so exemption was available. The lower authority's classification was set aside and consequential relief followed.

Issues: (i) Whether the imported lubricating unit was classifiable as a component of the grinding machine under Heading 8466.93 or as a spare part under Heading 84.79.89; (ii) whether the imported item was entitled to exemption under Notification No. 156/86-Cus.

Issue (i): Whether the imported lubricating unit was classifiable as a component of the grinding machine under Heading 8466.93 or as a spare part under Heading 84.79.89.

Analysis: The item was found to be specifically designed and manufactured for fitment only in the appellant's ELB surface grinder. It was essential for the sustained operation of the machine tool, supplying lubrication and controlling hydraulic functions, and its operation was integrally linked to the machine. On these facts, the item was treated as a machine-specific component rather than a general spare part.

Conclusion: The item was correctly classifiable under Heading 8466.93 as a component of the machine tool, in favour of the assessee.

Issue (ii): Whether the imported item was entitled to exemption under Notification No. 156/86-Cus.

Analysis: Once the item was held to be a component part of the machine tool and classifiable under Heading 8466.93, the exemption notification applicable to component parts of machine tools followed. The earlier tribunal decisions relied upon supported availability of the exemption in such cases.

Conclusion: The exemption under Notification No. 156/86-Cus. was available, in favour of the assessee.

Final Conclusion: The classification adopted by the lower authority was set aside and the appeal succeeded with consequential relief.

Ratio Decidendi: A machine-specific item essential for the operation of a particular machine tool is to be treated as a component part, and not merely as a spare part, for tariff classification and exemption purposes.
