Rough investment castings remain castings until machining gives them the essential character of firearm parts, avoiding licensing restrictions.

Rough investment castings intended for firearm use do not become parts of a firearm unless they have lost the character of castings and acquired the essential character of finished components through sufficient machining and processing. Applying the distinction between raw castings, proof-machined castings and finished machine parts, the Tribunal found the exported goods remained rough and unfinished and still required substantial machining and heat treatment before use in a shotgun. As they had not reached the stage of usable firearm parts, the Arms Act licensing requirement and customs confiscation provisions did not apply, and the confiscation and penalty could not stand.

Issues: Whether rough investment castings intended for use as firearm components had acquired the essential character of parts of a fire arm so as to attract the licensing requirement under the Arms Act and render the export prohibited.

Analysis: The Tribunal applied the settled distinction between raw castings, proof-machined castings and finished machine parts. It noted that the earlier classification principle requires the article to lose the character of a casting and become ready for use as a component before it can be treated as a part of a machine or firearm. On the technical evidence, the exported goods were rough and unfinished castings requiring substantial machining and heat treatment before they could be used in a shotgun. The reference to investment castings as generally near perfect did not displace the ratio governing the present goods, because the sample before the Tribunal had not reached the stage of a usable firearm part. The reliance on the Arms Act and the customs confiscation provisions therefore failed once the goods were held not to have acquired the essential character of firearm parts.

Conclusion: The goods were not firearm parts in law, no licence was required for export, and the confiscation and penalty could not stand. The appeal succeeded in favour of the assessee.

Ratio Decidendi: A rough casting remains a casting until it has undergone sufficient machining and processing to acquire the essential character of the finished part; only then can it be classified and treated as a prohibited or licensable component.
