Customs exemption for printer mechanisms cannot be denied without evidence on the goods' actual technical composition.

Exemption under Notification No. 17/2001-Cus depended on whether the imported printer mechanism was an assembly containing a populated printed circuit board. The denial of concession was unsustainable because the lower authorities did not properly examine the physical composition of the goods, did not obtain expert opinion, and relied on an unverified assumption rather than evidence. The importers' technical material, including a Government testing and certification opinion, was not duly considered. The impugned orders were therefore set aside, and the notification benefit was restored with consequential relief.

Issues: Whether the imported printer mechanism fell within an assembly containing a populated printed circuit board so as to deny the benefit of Notification No. 17/2001-Cus dated 01.03.2001.

Analysis: The notification granted concessional duty to parts falling under the relevant tariff heading, but excluded assemblies containing specified components such as a populated printed circuit board. The lower authorities had not properly examined whether the imported item contained such a board, nor had they obtained any expert opinion to support the departmental allegation. The importers' technical material, including the opinion from a Government testing and certification body, was not considered, and the reasoning proceeded on an unverified assumption rather than on evidence.

Conclusion: The denial of exemption was unsustainable and the impugned orders were liable to be set aside.

Final Conclusion: The appeals succeeded and the appellants were entitled to the consequential relief flowing from restoration of the notification benefit.

Ratio Decidendi: Where exemption under a technical customs notification turns on the physical composition of the imported goods, denial of the benefit cannot rest on unsupported assertions and must be backed by proper examination and expert evidence.
