Customs classification turns on physical characteristics, not trade name, while port rent may follow the statutory schedule of rates.

For exemption under a customs notification, imported goods are classified by their physical characteristics and substance of the tariff description, not by trade nomenclature alone. On that approach, thin imported plastic film could fall within the notified category of sheets, foils or similar flexible forms, but the text states that the challenge to additional customs duty ultimately failed and exemption was not available. The article also notes that a Port Trust may recover rent in accordance with the schedule of rates framed under the governing port law, and that claim was upheld.

Issues: (i) Whether imported plastic film fell within the description in Notification No. 228/76-Cus. so as to qualify for exemption from additional customs duty under Section 3 of the Customs Tariff Act; (ii) Whether the Port Trust was entitled to recover rent according to the schedule of rates under the Major Port Trust Act.

Issue (i): Whether imported plastic film fell within the description in Notification No. 228/76-Cus. so as to qualify for exemption from additional customs duty under Section 3 of the Customs Tariff Act.

Analysis: The notification covered tubes, rods, sheets, foils, sticks, other rectangular or profile shapes, whether laminated or not and whether rigid or flexible, including layflat tubings and polyvinyl chloride sheets. The test report indicated that the imported goods were thin and their thickness could be equated with foil. The mere description of the goods as plastic film did not take them outside the scope of the notification when their physical characteristics brought them within the relevant entry.

Conclusion: The imported goods were not entitled to exemption from additional customs duty, and the challenge to the levy failed.

Issue (ii): Whether the Port Trust was entitled to recover rent according to the schedule of rates under the Major Port Trust Act.

Analysis: The claim of the Port Trust was accepted and it was clarified that rent was recoverable in accordance with the schedule of rates prepared under the governing port law.

Conclusion: The Port Trust was entitled to recover rent according to the applicable schedule of rates.

Final Conclusion: The writ petition failed on the challenge to additional customs duty, the interim protection was vacated, and the connected claim of the Port Trust was upheld.

Ratio Decidendi: For exemption under a customs notification, the goods must answer the substance of the tariff description as understood from their physical characteristics, and a contrary trade nomenclature will not defeat liability where the goods otherwise fall within the notified entry.
