Customs exemption for aircraft engine parts upheld where components were specifically designed and integral to fighter aircraft use.

The customs exemption under Serial No. 545 of Notification No. 50/2017-Customs was held applicable to parts of turbo-jet engines used in fighter aircraft because the entry covered parts of aircraft falling under any chapter unless expressly excluded. The ruling applied the plain language of the notification and the settled rule that exemption provisions must be construed strictly according to their terms. It also accepted that specially designed components used solely as integral parts of aircraft engines may qualify as parts of aircraft, including where a part of a part is functionally integral to the whole. On that basis, the imported parts were found eligible for concessional customs treatment.

Issues: Whether exemption under Serial No. 545 of Notification No. 50/2017-Customs dated 30.06.2017 is admissible to parts of turbo-jet engines used in fighter aircraft.

Analysis: The notification grants exemption to parts of aircraft falling under any chapter, except the specified exclusions. The goods were stated to be specifically designed for use only in turbo-jet engines of fighter aircraft and not for general use. The ruling applied the plain language of the exemption entry and the settled principle that exemption notifications must be construed according to their terms. It also accepted the principle that a part of a part can, in appropriate circumstances, be treated as part of the whole where the use is specific and integral to the aircraft.

Conclusion: The exemption under Serial No. 545 of Notification No. 50/2017-Customs dated 30.06.2017 is admissible to the imported parts of turbo-jet engines used in fighter aircraft.

Final Conclusion: The applicant was held entitled to the concessional customs exemption for the subject imported parts as falling within the notified entry for parts of aircraft.

Ratio Decidendi: Where an exemption entry covers parts of aircraft falling under any chapter, specifically designed components used solely as integral parts of aircraft engines may qualify for the exemption if they are not expressly excluded and the notification language plainly supports the benefit.
