In re Bird flight Services Pvt Ltd (CAAR Delhi)
Customs Authority for Advance Rulings (CAAR), Delhi, in In re Bird Flight Services Pvt. Ltd., examined the classification of two aircraft ground support equipment — an Air Start Unit (ASU GS-400) and an Air Conditioning Unit (ACU GF-50) — under the Customs Tariff Act, 1975. The key issue was whether these units, designed exclusively for use with aircraft on the ground, were classifiable as “parts of aeroplanes” under Heading 8807 or as general air-conditioning machinery under Heading 8415.
Background and Product Description
The applicant sought an advance ruling for two specialized items used in ground handling of aircraft:
-
Air Start Unit (ASU GS-400) – a ground support equipment (GSE) that provides high-pressure, temperature-controlled air to start aircraft engines when the aircraft’s auxiliary power unit (APU) is inoperative.
-
Air Conditioning Unit (ACU GF-50) – a GSE that supplies pre-conditioned air (heating, cooling, and ventilation) to the aircraft cabin and avionics while the aircraft is parked, functioning as a temporary substitute for the onboard APU.
Both machines are built to operate within the precise parameters required by aircraft systems and have no general industrial or commercial utility.
Arguments by Applicant and Department
The applicant contended that both the ASU and ACU were aircraft-specific ground systems, integrally linked to aircraft operations. They are used exclusively for aircraft servicing and not in any other context, and thus qualify as “parts” of aircraft under Tariff Heading 8807 30 10 (“Other parts of aeroplanes, helicopters”).
The jurisdictional Commissionerate, however, agreed with this classification only for the ASU, while opposing it for the ACU.
