Exemption for essential machine parts: specially designed chill moulds qualified for relief despite a different tariff heading.

An exemption notification covering casting machines and their parts applied to chill moulds imported for a centrifugal casting machine because the moulds were specially designed and integral to the machine's operation. The rival tariff classification under another heading in Chapter 84 did not disqualify the benefit, as the operative test was whether the goods were parts of the casting machine, not the precise heading used for assessment. The note confirms that an essential, specially designed component may qualify as a part for exemption purposes even where it is classified differently within the same chapter.

Issues: Whether chill moulds imported for a centrifugal casting machine were entitled to exemption under Notification No. 23/91-Cus. as parts of casting machines, notwithstanding their rival tariff classification.

Analysis: The exemption entry covered casting machines of a kind used in metallurgy and metal foundries, together with parts thereof, in Chapter 84. The chill moulds were found on the technical material and manufacturing process to be specially designed and integral to the centrifugal casting machine. Reliance was placed on the earlier view that moulds forming an essential component of a casting machine qualify as parts for the purpose of a similarly worded exemption notification. The fact that the goods had been assessed under a different heading within Chapter 84 did not defeat the notification benefit, because the operative question was whether they were parts of the casting machine and not the precise rival heading adopted for classification.

Conclusion: The chill moulds were held entitled to the benefit of Notification No. 23/91-Cus. as parts of the centrifugal casting machine, irrespective of classification under the competing headings.

Final Conclusion: The appeal succeeded and the duty exemption was extended to the imported chill moulds on the footing that a beneficial notification covering parts of casting machines applies to an essential, specially designed component even if it is assessed under a different heading within the same chapter.

Ratio Decidendi: Where an exemption notification expressly covers parts of casting machines, an essential and specially designed component of such machine is eligible for the benefit even if classified under a different tariff heading within the same chapter.
