These products, which are defined in Chapter Notes 1 (a), 1 (b) and 1 (c), correspond to similar goods made of copper. The provisions of the Explanatory Notes to headings 74.07 and 74.08 therefore apply, mutatis mutandis, to this heading. Rods and profiles of zinc are often used to make fabricated building components (heading 79.07); the main use of zinc wire is as a source of zinc for spraying the metal from an oxy-acetylene pistol. The heading also includes brazing or welding rods of zinc base alloys (generally made by extrusion) whether or not cut to length, provided they are not coated with flux material. Coated rods are excluded (heading 83.11). The heading also excludes cast rods intended, for example, for rolling or drawing or for re-casting into shaped articles (heading 79.01).
