Defence aircraft customs exemption depends on functional end-use nexus and mandatory import certification, not individual tariff headings.
Defence-aircraft customs exemption for imported parts, sub-assemblies and accessories operates on functional character and qualifying end use rather than individual tariff classification. Prefabricated missile-warning system components integrated into a military helicopter's electronic-warfare suite may fall within the exemption where their exclusive defence nexus is established. Eligibility remains conditional on satisfying the prescribed certification requirement at importation; end-use documents do not replace that certificate. Advance-ruling admission requires a valid importer-exporter code, a question on proposed imports, payment of the prescribed fee, and no identical pending or previously decided question for the applicant. Classification and consignment-level verification remain for import assessment.
Issues: (i) Whether the advance-ruling application concerning the proposed imports was maintainable; (ii) Whether MILDS F SUOF Lens, Front End (M2FE), and MILDS F SUII Coupled units were eligible for exemption under Sl. No. 60 of Table II to Notification No. 45/2025-Customs dated 24.10.2025.
Issue (i): Whether the advance-ruling application concerning the proposed imports was maintainable.
Analysis: The applicant held a valid Importer-Exporter Code, the question concerned the applicability of an exemption notification to goods proposed to be imported, and no identical question was pending or had been decided in the applicant's case. The imports had not occurred and the prescribed fee had been paid.
Conclusion: The application was maintainable and admitted for a ruling.
Issue (ii): Whether MILDS F SUOF Lens, Front End (M2FE), and MILDS F SUII Coupled units were eligible for exemption under Sl. No. 60 of Table II to Notification No. 45/2025-Customs dated 24.10.2025.
Analysis: Sl. No. 60 is a functional and end-use based exemption covering parts, sub-assemblies and accessories for specified defence equipment, including aircraft, across any tariff chapter. Individual tariff classification does not determine eligibility, but a demonstrable nexus with the qualifying end-use aircraft and fulfilment of Condition No. 17 are necessary.
Analysis: The imported units are separately manufactured, prefabricated components engineered to form the missile-warning system, which is fitted as part of the electronic-warfare suite of military helicopters. They accordingly qualify as sub-assemblies and, alternatively, accessories for aircraft. The end-use documentation established the exclusive defence nexus, but could not substitute the certificate prescribed under Condition No. 17 for exemption at the time of import.
Conclusion: The goods qualify for the exemption under Sl. No. 60, subject to compliance with Condition No. 17 and verification at importation, in favour of the assessee.
Final Conclusion: The ruling confines notification coverage to the described goods; tariff classification and consignment-level certification and verification remain for assessment at the time of import.
Ratio Decidendi: A functional, end-use based customs exemption applies where imported components have a demonstrable nexus with the specified defence end-product, irrespective of their individual tariff headings, provided the notification's mandatory certification condition is fulfilled.
