Imitation jewellery See note 11 to this chapter. Of base metal, whether or not plated with precious metal These subheadings include: 1. chain of base metal, cut into lengths each of which is suitable for finishing into a single piece of imitation or costume jewellery by, for example, attaching fasteners. Such lengths will not normally exceed two metres; 2. ornamental motifs of base metal, covered by the HS Explanatory Note to heading 7117 , second paragraph, (b), examples of which are given below: General Waste or scrap from non-ferrous metals which has been melted down and cast into ingots, pigs, blocks or similar forms is classified as unwrought metal and not as waste or scrap. It is consequently classified, for example, in heading 7601 (aluminium), 7801 (lead), 7901 (zinc) or in subheading 8104 11 00 or 8104 19 00 (magnesium). The expression ‘metal’ is taken to include also metal which has an amorphous (non-crystalline) structure, such as metallic glasses and powder metallurgy products. General There is a number of ways of distinguishing between forged and rolled products, where this distinction needs to be made (headings 7207 , 7214 , 7216 , 7218 , 7224 and 7228 ). dimensions of the cross-section shape of the cross-section length dimensional tolerances metallographic aspect inclusions in rolled products are thin, very elongated and almost perfectly parallel to the direction of rolling; in forged products, on the other hand, they are less elongated (almost elliptical in shape) and are not perfectly parallel; the structure of rolled products examined after annealing, if the product has been hardened and tempered, has almost perfectly rectilinear division marks parallel to the direction of rolling. In forged products, on the other hand, this is much less common and sometimes almost non-existent; quantity For the definition of certain types of plastic deformation (such as rolling, forging, stamping), see the HS General Explanatory Note to Chapter 72, part (IV), (A) and (B). For the difference between hot-rolled or hot-drawn products and products obtained or finished in the cold state, see the HS General Explanatory Note to Chapter 72, part (IV), (B), final paragraph. For the definition of cladding, see the HS General Explanatory Note to this chapter, part (IV), (C), (2), (e). For comments on surface treatments, see the HS General Explanatory Note to Chapter 72, part (IV), (C), (2), (d). Unfinished forgings no longer having the rough appearance of pieces roughly shaped by forging of heading 7207 , 7218 or 7224 are to be classified in the headings appropriate to the finished articles, which are generally in Chapters 82, 84, 85 and 87. Thus, iron or steel forgings for the manufacture of crankshafts are proper to heading 8483 .
