If, however, they have been worked geyond this stage, they are classified in ths heading, provided that they have not thereby assumed the character of articles or of products of other headings. dY Wire-bars and billets with their ends tapered or otherwise worked simp1 to facilitate their en% inp machines for converting them into, e-g., wire drawing stock (wire-rod) or tu es, are, however, class1 ed in heading 74.03. i:
1.- In this Chapter the following expressions have the meanings hereby assigned to them : (a) Refined copper Metal containing at least 99.85 % by weight of copper; or Metal containing at least 97.5 % by weight of copper, provided that the content by weight of any other element does not exceed the limit specified in the following table : TABLE - Other elements Element Limiting content % by weight Ag Silver 0.25 As Arsenic 0.5 Cd Cadmium 1.3 Cr Chromium 1.4 Mg Magnesium 0.8 Pb Lead 1.5 S Sulphur 0.7 Sn Tin 0.8 Te Tellurium 0.8 Zn Zinc 1 Zr Zirconium 0.3 Other elements*, each 0.3 * Other elements are, for example, Al, Be, Co, Fe, Mn, Ni, Si. (b) Copper alloys Metallic substances other than unrefined copper in which copper predominates by weight over each of the other elements, provided that : (i) the content by weight of at least one of the other elements is greater than the limit specified in the foregoing table; or (ii) the total content by weight of such other elements exceeds 2.5 %. (c) Master alloys Alloys containing with other elements more than 10 % by weight of copper, not usefully malleable and commonly used as an additive in the manufacture of other alloys or as de-oxidants, de- sulphurising agents or for similar uses in the metallurgy of non-ferrous metals. However, copper phosphide (phosphor copper) containing more than 15 % by weight of phosphorus falls in heading
