It is the contention of the appellant that after the materials are cast, they are subjected to what is referred to as proof machining . This, he says, is an operation that is intended to remove excess material on the surface, so as to locate the presence of surface defects. Such proof machining, he says, does not amount to further working of the casting. He cites the Explanatory Notes to the Harmonized System of Nomenclature to Headings 7320.11 to 7419.91 in which certain operations to which castings or forgings of iron and steel may be subjected .....

It does not appear to us that the tariff in its structure contemplates the existence of goods at various stages between what emerges after casting and or forging and classification of the finished article of finished product from machinery parts. Whether any of these intermediary processes, the sum total of which may result in converting the product into casting or moulding to a finished product would by itself constitute a manufacture is also doubtful. However, further discussion is not really required on this issue, s ..... X X X X Extracts X X X X X X X X Extracts X X X X
