Strict proof for customs exemption fails where documentary and technical evidence does not link imported machinery to the notified goods.

Eligibility for exemption under a customs notification must be strictly proved by cogent documentary and technical evidence. The importer of a special purpose metal ring machine failed to establish that the goods matched the machine described in Notification No. 40/78-Cus., because the Bill of Entry, invoice, certificate, literature and other material did not satisfactorily correlate the imported machine with the notified equipment. The adverse findings of the lower authorities were not rebutted with adequate supporting data, so the claim for concessional customs duty failed and the exemption was denied.

Issues: Whether the imported special purpose metal ring machine was eligible for exemption under Notification No. 40/78-Cus., dated 1-3-1978.

Analysis: The notification granted concessional customs duty to specified Chapter 84 machines, including an automatic flow forming machine for manufacture of seamless tubes and other cylindrical components of metals with or without numerical control. The claim for exemption had to be substantiated by reliable documentary and technical evidence. On the record, the description in the Bill of Entry and invoice, the available certificate and literature, and the other material produced did not satisfactorily establish a co-relation between the imported machine and the machine covered by the notification. The importer also failed to rebut the adverse observations of the lower authorities or produce adequate supporting data.

Conclusion: The imported machine was not proved to fall within the scope of the exemption notification, and the claim for concessional duty failed.

Final Conclusion: The appeal was rejected as the importer did not establish entitlement to the exemption from customs duty.

Ratio Decidendi: A person claiming exemption under a customs notification must strictly prove eligibility with cogent documentary and technical evidence, and doubtful or piecemeal material is insufficient to extend the benefit.
