Interchangeable engine parts exemption denied for tractor piston rings absent proof of non-interchangeability.

Piston rings imported for tractors were held ineligible for exemption under Notification No. 172/89-Cus. because the notification excluded parts of engines interchangeable for use in motor vehicles, and tractors fall within that category under the Motor Vehicles Act, 1988. The importer produced no technical material, catalogues, or other evidence to show that the goods were exclusively for a non-interchangeable engine or incapable of use with other motor vehicles. In the absence of such proof, the exclusion applied and concessional treatment was denied; the appeal therefore failed.

Issues: Whether piston rings imported for tractors were eligible for exemption under Notification No. 172/89-Cus. when the exemption excluded parts of engines interchangeable for use in motor vehicles.

Analysis: The imported goods were declared and found to be piston rings for Eicher tractors. Tractors fall within the definition of motor vehicle under Section 2(44) of the Motor Vehicles Act, 1988. The appellant produced no supporting material, such as catalogues or technical documents, to show that the piston rings were exclusively for a non-interchangeable engine or were incapable of use with other motor vehicles. In the absence of such proof, the exclusion in the notification applied.

Conclusion: The exemption was not available and the denial of benefit was in law, against the assessee and in favour of the Revenue.

Final Conclusion: The imported piston rings did not qualify for concessional treatment under the notification, and the appeal failed.

Ratio Decidendi: Where an exemption notification excludes parts of engines interchangeable for use in motor vehicles, the claimant must establish by evidence that the imported goods are not so interchangeable; failing that, exemption cannot be granted.
