Strict construction of customs exemptions denied benefit for powerchute parts outside the notification's specific aeroplane description.

Imported powerchute/parawing goods were examined under the Aircraft Rules, Chapter 88 tariff headings and the HSN Notes, and were treated as powered hang gliders with parts classifiable under Heading 88.03. The exemption in Notification No. 145/77-Cus. was limited to aeroplanes, aeroplane parts, aeroplane engines, aeroplane engine parts, and rubber tyres and tubes used exclusively for aeroplanes. Because the notification used specific terms, the concession could not be extended by analogy to goods merely falling within the wider aircraft tariff structure. The claimed customs exemption therefore failed, and the import was not entitled to benefit under the notification.

Issues: Whether the imported powerchute/parawing goods were classifiable as aeroplane parts so as to qualify for exemption under Notification No. 145/77-Cus.; and whether the benefit of the notification was admissible to the appellants.

Analysis: The goods were examined in the light of the Aircraft Rules, the tariff headings in Chapter 88, and the HSN Explanatory Notes. The distinction between aeroplanes, gliders, and powered hang gliders was considered, and it was concluded that powered hang gliders are classifiable under Heading 88.02, with their parts under Heading 88.03. However, Notification No. 145/77-Cus. expressly exempts only aeroplanes, aeroplane parts, aeroplane engines, aeroplane engine parts, and rubber tyres and tubes used exclusively for aeroplanes. Since the notification uses specific terms, the exemption could not be extended merely because the goods were parts of an aircraft falling under the tariff structure.

Conclusion: The imported powerchute goods were not entitled to exemption under Notification No. 145/77-Cus., and the claim failed.

Final Conclusion: The appeal was rejected because the goods did not fall within the specific scope of the exemption notification.

Ratio Decidendi: A concessional customs exemption must be construed strictly and can be claimed only when the imported goods squarely satisfy the specific description used in the notification.
