Expert laboratory report controls exemption claim for imported kraft paper where no contrary technical evidence is produced.

Imported creped kraft paper was held not to be established as electrical grade kraft paper qualifying for exemption under Notification No. 37-Customs dated 1-3-1978. The Customs authorities were entitled to rely on the National Test House laboratory report, which was supported by technical particulars and issued by a reputed expert body. Mere dispute by the importer about the standards applied was insufficient to displace that report, especially since no contrary test report or reliable technical material was produced. The denial of exemption was therefore sustained.

Issues: Whether the imported creped kraft paper was entitled to the benefit of Notification No. 37-Customs dated 1-3-1978, and whether the Customs laboratory test report could be relied upon to deny the exemption.

Analysis: The imported goods had been provisionally cleared, and the Customs authorities relied upon a sample obtained from the importer for testing. The Court found no basis to reject the test report of the National Test House, a reputed expert body, merely because the appellants disputed the applicability of the standards used. The report was supported by technical particulars, and the appellants produced no contrary test report or reliable technical material to displace it. On the materials available, there was no sufficient ground to hold that the report was invalid or that the goods answered the description required for the exemption.

Conclusion: The imported goods were not established to be electrical grade kraft paper entitled to the notification benefit, and the test report was rightly relied upon.

Final Conclusion: The order denying exemption was sustained and the appeal failed.

Ratio Decidendi: A duly issued expert laboratory report on the nature and quality of imported goods will ordinarily be accepted unless the importer produces convincing contrary technical evidence showing that the report is unreliable or inapplicable.
