Tariff classification of Ethernet switches affirmed as enterprise switches, entitling importers to the concessional customs duty under the applicable notifications.

The primary issue was whether enterprise-class Ethernet switches are classifiable under CTI 8517 6290 and therefore eligible for a concessional Basic Customs Duty entry in the cited notifications. The analysis applied tariff classification rules and HSN interpretation, gave weight to technical product characterisation and consistent departmental practice, and relied on coordinate-bench precedent holding Cisco Catalyst 3850-series and identical switches as enterprise (non-carrier) switches within CTI 8517 6290. The Tribunal found no evidence displacing the established classification and held that later notifications could not retrospectively alter classification where the Tariff Act remained unchanged; the impugned order was set aside and the concession allowed.

Issues: Whether Ethernet switches classified under Customs Tariff Item 8517 6290 are eligible for concessional Basic Customs Duty @10% under Serial No.20 of Notification No.57/2017-Customs as amended, and whether the impugned Order-in-Original denying the concession should be set aside.

Analysis: The Tribunal examined tariff classification rules and the scope of the exemption notifications (Notification No.24/2005-Customs dated 01.03.2005, Notification No.11/2014-Customs dated 11.07.2014 and Notification No.57/2017-Customs dated 30.06.2017 as amended), the historical practice of classification under CTI 8517 6290, and prior coordinate bench decisions addressing identical products and issues. The Tribunal considered technical opinions and the absence of evidence displacing the established classification, and applied the general rules of interpretation of tariff and HSN. The Tribunal relied on consistent prior orders holding that the relevant Cisco Catalyst 3850 series and identical enterprise-class Ethernet switches are enterprise (non-carrier) switches classifiable under CTI 8517 6290 and eligible for the concessional entry in the stated notifications. The Tribunal also noted that subsequent notifications relied upon by Revenue could not be applied retrospectively to change classification where no change in the Tariff Act exists and where prior coordinated precedent and departmental practice support the exemption.

Conclusion: The impugned order is set aside and the appellants are entitled to the concessional Basic Customs Duty @10% under the notification for Ethernet switches classified under CTI 8517 6290; the appeal is allowed in favour of the assessee.
