72.17 - Wire of iron or non-alloy steel (+). 72 17.10 - Not plated or coated, whether or not polished - Plated or coated with zinc 7217.30 - Plated or coated with other base metals 7217.90 - Other 7217.20 Wire of this heading is defrned in Note 1 (0) to this Chapter. r, Wire is most1 produced from hot-rolled bars and rods of heading 72.13 by drawing them through a die ut may also be obtained by any other cold-forming process (e.g.,, cold-rolling). Wire is presented in coils (with non-aligned spirals or with aligned spirals, wlth or without support). Wire which has been worked e.g., by crim ing) remains in this heading, provided it does not thereby assume the character o articles or o products of other headings. i ! Wire covered with a material such as textile where the iron or steel core is the essential element and the other material serves solely as covering (e. ., iron and steel wire for the manufacture of hat fr-ames (milliners' wire), and stems for artxficia flowers or hair curlers) is also classified in this heading. f Wire is put to very many uses, e.g., manufacture of fencing, gauze, netting, nails, rope, pins, needles, tools and springs. The heading does not cover (a) Metallised yarn (heading 56.05), twine or cord reinforced with wire (heading 56.07). (b) Stranded wire, ropes, cables and the like of beading 73.12. (c) Barbed wire; twisted single flat wire (barbed or not) of a kind used for fencing (heading 73.13). (d) " Duplex " wire as used for making textile loom healds and formed by soldering together two wire strands after drawing, wire twisted into eyelets or loops at one or both ends for tying (heading 73.26). (e) Coated welding electrodes, etc. (heading 83.11). (f) Saw-toothed wire for use as card clothing (all-steel card clothing) (heading 84.48). (g) Insulated electric wire (including enamelled wire) (heading 85.44). (h) Musical instrument strings (heading 92.09). Subheading Explanatory Note. See the Explanatory Note to the subheadings of heading 72.10 in respect of products subjected to more than one type of coating, plating or cladding. Sub-chapter I11 STAINLESS STEEL GENERAL Heat-resisting steel, creep-resisting steel and any other steel complying with the specified criteria in Note 1 (e) to this Chapter are to be classified as stainless steel. f Because of its hi resistance to corrosion, stainless steel is put to a very wide range of uses, e.g., in the manu actme of silencers, catalytic converters or transformer tanks. This sub-chapter covers stainless steel in the forms mentioned in headings 72.18 to 72.23. 72.18- Stainless steel in ingots or other primary forms; semi-finished products of stainless steel. - Ingots and other primary f o m - Other : 7218.91 - - Of rectangular (other than square) cross-section 7218.99 - - Other 72 18.10 The provisions of the Explanatory Note to headings 72.06 and 72.07 apply, mutatis mutandis, to the products of this headmg.
1.- In this Chapter and, in the case of Notes (d), (e) and (f) throughout the Nomenclature, the following expressions have the meanings hereby assigned to them : (a) Pig iron Iron-carbon alloys not usefully malleable, containing more than 2 % by weight of carbon and which may contain by weight one or more other elements within the following limits : - not more than 10 % of chromium - not more than 6 % of manganese - not more than 3 % of phosphorus - not more than 8 % of silicon - a total of not more than 10 % of other elements. (b) Spiegeleisen Iron-carbon alloys containing by weight more than 6 % but not more than 30 % of manganese and otherwise conforming to the specification at (a) above. (c) Ferro-alloys Alloys in pigs, blocks, lumps or similar primary forms, in forms obtained by continuous casting and also in granular or powder forms, whether or not agglomerated, commonly used as an additive in the manufacture of other alloys or as de-oxidants, de-sulphurising agents or for similar uses in ferrous metallurgy and generally not usefully malleable, containing by weight 4 % or more of the element iron and one or more of the following : - more than 10 % of chromium - more than 30 % of manganese - more than 3 % of phosphorus - more than 8 % of silicon - a total of more than 10 % of other elements, excluding carbon, subject to a maximum content of 10 % in the case of copper.
