Subheading Explanatory Note. Subheading 7108.20 This subheading covers gold exchanged between national or international monetary authorities or authorisedbanks. - 71.09 Base metals or silver, clad with gold, not further worked than semi-manufactured. Metal clad with precious metal (incIuding base metal inlaid with Note 7 and the General Explanato Note to this Chapter. Base usually in forms similar to those escribed for base metal clad with Note to heading 7 1.07). Base metal (e.g., copper and its alloys) or silver is clad with gold for the manufacture of 'ewellery (bracelets, watch-chains, ear-rings, etc.), watch-cases, cigar or cigarette-holders, lighters, goldsmiths' wares, electrical contacts, chemical apparatus, etc. 71.10 - Platinum, unwrought or in semi-manufacturedforms, or in powder form. - Platinum : 7 110.11 - - Unwrought or in powder form 7110.19 - - Other - Palladium : 7 110.21 - - Unwrought or in powder form 7110.29 - - Other - Rhodium : 71 10.31 - - Unwrought or in powder form 71 10.39 - - Other - Iridium, osmium and ruthenium : 71 10.41 - - Unwrought or in powder form 7110.49 - - Other Like headings 71-06 for silver and 71.08 for gold, this heading covers platinum and its alloys as defined in the General Explanatory Note. * * + The tenn " platinum " covers (see Note 4 (B) to Chapter 71) : (A) Platinum which is a greyish-white, soft and ductile metal, not tarnished at room temperature and resistant to acids except aqua regia. It can be fabricated into bars, sheets, strip, tubes, wire and other semi-manufactured forms by forging, rolling or drawing. In view of their outstandin resistance to corrosion, high melting point and high catalytic activity, platinum and its a loys have many important applications in industry surpassing their use in jewellery or in dentistry, for example, in the electrical industry for the manufacture of thermocouples and resistance thermometers, and as electrical contacts and electrodes for various applications; in the textile industry for spinnerets for man-made fibres; in the glass industry for molten glass equipment such as bushings for glass fibre production, crucibles, stirrers, etc.; in the chermcal and petroleum industries as catalysts (e.g., in, the ammonia-oxidation process for the manufacture of nitric acid or as a platfomng catalyst); as chemical ap aratus (e.g., crucibles); in the aircraft industry for electrodes of sparking plugs for spar!-ignition mtemal combustion aero-engines and for ignition devices in gas-turbme aero-engines. Platinum and its alloys also find a use in the manufacture of surgical instruments (particularly hypodermc needles), in certain gas lighters and for many other applications such as measuring standards, hair lines for ophcal instruments, etc. a (B) Palladium which is a silvery-white metal, soft, ve ductile and highly resistant to tarnishing and corrosion. It dissolves in aqua regia an nitric acid and is attacked by hot sulphuric acid. Palladium can be made into bars, sheets, strip, tubes, wire or other semimanufactured forms by forging, rolling or drawing. It is mainly used for electrical contacts, in brazing alloys, in hydro en purification equipment, as a hydrogenation catal st, in the manufacture of jewe lf ery and as an intermediate contact layer to facilitate Xe coating of plastics with precious metals. (C) Rhodium which is a silve -white, hard but ductile metal. It is characterised by its high reflectivity and has the hizest electrical and thermal conductivities of all the platinum group metals. It is resistant to corrosion by nearly all aqueous solutions, including mineral acids even at high temperatures. Rhodium may be made into bars, sheets, strip, wire and other semi-manufactured forms by forging, rolling or drawing. Its major use is as an alloyin addition to platinum and in this form it has several applications in the electrical an glass-making mdustries. Its low electrical resistance and hgh resistance to tarnishing make it suitable, in the electrodeposited form, for electrical contacts and for contact surfaces where wear resistance is of importance (e.g., in slip rings). It is also used as a catalyst and for plating silver or silver-plated cutlery and hollowware to give a tarnish resistant finish. % (D) Iridium which is a greyish-white, hard metal, resistant to the action of acids, including aqua regia, at normal and high temperatures. It can be made into thin strip or wire by rolling and drawing. Iridium is used as a constituent of alloys used for thermocouples, crucibles, or electrodes for aircraft-engine sparking plugs. (E) Osmium which is the most refractory of the metals included in this headin . In the % corn act state it has a bluish-white colour similar to zinc and is resistant to aci s. When fineg divided, it is an amorphous black owder, and is attacked by nitric acid and aqua regia and is slowly oxidised in the atmosp ere. R The metal is mainly used in various, hard, corrosion-resistant alloys used for tipping pennibs or instrument pivots. It is also used as a catalyst. (F) Ruthenium which is a brittle, hard, grey metal. It has a high resistance to corrosion. It is unattacked by aqua regia, but is slow1 attacked by solutions of sodium hypochlorite. It can be obtained on a small scale in the o m of sheets, strip and wire. ? It is used as an alloying addition to platinum, palladium, molybdenum, tungsten, etc. (e.g., for the manufacture of en-nib oints and compass pivots). It is also used as a catalyst and, in the electrodeposite form, or electrical contacts and for contact surfaces where wear resistance is of importance. ? Under the terms of Note 5 to this Chapter see General Ex lanatory Note), the alloys of platinum with other metals (gold, silver or base metals) wRich may fall m this heading, include : (1) Platinum-rhodium alloys, - thermocouple wire; furnace windings; components in the glass industry; catalyst gauzes; spinnerets.

(17) Osmiridium (iridosmine), a natural alloy containing osmium, iridium, ruthenium and platinum; it is the main source of osmium. 71.11 - Base metals, silver or gold, clad with platinum, not further worked than semimanufactured. Metals clad with recious metal (including those inlaid on base metal with precious metal) are defied in Note to this Chapter and m the General Explanatory Note. They are usually resented in forms similar to those described for silver in the Explanatory Note to !eading 71.07. Base metals (e-g., copper, tungsten), silver or gold, clad with platinum are used mainly in jewellery and in electrical apparatus. 71.12 - Waste and scrap of precious metal or of metal clad with precious metal; other waste and scra containing precious metal or precious metal compounds, of a kind used principal y for the recovery of precious metal.
