Component parts of a water turbine may qualify for customs exemption when admitted end-use evidence proves their functional role.

Additional evidence, including end-use affidavit, essentiality certificate, drawings and catalogue, was admitted on record because the Revenue raised no objection to its consideration. On that evidence, the imported potentiometers and displacement transducers were treated as component parts of a water turbine, qualifying for classification under Tariff Item 84.07 and exemption under Notification No. 35/79 dated 15-2-1979. The appellate order was set aside after the goods were found eligible for the claimed customs benefit on the basis of their established end use and functional role in the turbine assembly.

Issues: (i) Whether the additional documents produced before the Tribunal could be admitted and relied upon in support of the claim for exemption; (ii) whether the imported potentiometers and displacement transducers were component parts of a water turbine entitled to classification under Tariff Item 84.07 of the Customs Tariff Act, 1975 and exemption under Notification No. 35/79 dated 15-2-1979.

Issue (i): Whether the additional documents produced before the Tribunal could be admitted and relied upon in support of the claim for exemption.

Analysis: The Tribunal accepted the end-use affidavit, essentiality certificate, drawings, catalogue, and the additional drawings showing the actual use of the goods in the turbine assembly. The Revenue raised no objection to their admission if taken on record by the Bench.

Conclusion: The additional evidence was admitted and considered in support of the appeal.

Issue (ii): Whether the imported potentiometers and displacement transducers were component parts of a water turbine entitled to classification under Tariff Item 84.07 of the Customs Tariff Act, 1975 and exemption under Notification No. 35/79 dated 15-2-1979.

Analysis: On the admitted evidence, the goods were shown to be component parts of the water turbine. They were found to fall under Tariff Item 84.07 of the Customs Tariff Act, 1975 and to satisfy the requirements of Notification No. 35/79 dated 15-2-1979.

Conclusion: The claim for classification under Tariff Item 84.07 and exemption under Notification No. 35/79 was allowed.

Final Conclusion: The order of the Appellate Collector was set aside and the appeal succeeded on the basis that the imported goods were eligible component parts for the claimed customs exemption.

Ratio Decidendi: Where the evidentiary record establishes that imported goods are component parts of the specified end-use machinery, exemption cannot be denied merely because supporting documents were produced at the appellate stage and are accepted on record.
