I % P It should also be noted that many parts do not fall in this heading since they are (a) Specified elsewhere in the Nomenclature, e-g., suspension springs (headin 73.20), engines (heading 84.07 or 84.08, etc.) and electrical igmtion or starting equipment (hea ing 85.11). d (b) Parts identical with those for motor vehicles and not suitable for use solely or principally with the machinery of headlngs 84.25 to 84.30, and therefore classified as parts of motor vehicles (heading 87.08); this applies in particular to wheels and steering and brahng equipment. or (c) Parts suitable for use solely or principally with the machinery for lifting, handling, loading or unloadin boules, wafers, semiconductor devices, electronic integrated circults or flat panel displays ?heading 84.86). The heading includes : (1) Lifting grabs, buckets, grips, etc., i.e., simple lifting buckets fitted with attachin rings, hooks, etc.; hinge-bottomed buckets; grabs consistmg of two jointed shells w ich fit together for lifting powdery materials; grips consisting of two or more jointed blades or claws for handling stone, rocks, etc. g Electromagnetic lifting heads for handling scrap metal, etc., are also excluded (heading 85.05). (2) Drums for winches or capstans; crane jibs; trolleys, crabs, buckets, skips, etc., for overhead transporters; cabins, cages and platforms for lifts, etc.; escalator steps; buckets and scraper chains for elevators and conve ors; supports, and drums or rollers (whether or not incorporating driving motors) or conveyors; driving and retarding heads for shaker conveyors and tables; safety stopping mechanisms for lifts, skip-hoists, etc. f' (3) Cutter bars, chains and jibs for coal cutters; blades for scrapers, coal ploughs and strippers, etc. This group also covers bulldozer or angledozer blades intended to be mounted as working tools on vehicles of Chapter 87. (4) Rotary tables, swivels, kellies, keIly drive bushings, tool-joints, drill collars, subs, drill ipe guides, sto -collars, spider bowls, split bushing sli s, beams, swivel sockets, and dri ing jars, for we 1drilling machines (rotary or percussionr. ti (5) Digging buckets and abs for excavators, bucket ladders for multi-bucket excavators; jibs for mechanical shove s, pile-driver hammers. F (6) Track-laying or wheeled chassis, not self-propelled, fitted with swivel gear or other rotating devices. Cables and chains equip ed with their fittings (e.g., cable clips, rin s, hooks and spring hooks) are classified wd! the machinery for which they are intendel rovided they are resented therewith. When resented separately, however, they are classi led in Section XV usually heading 73.12 or 3.15). Cables and chains not equipped with such fittings and presented in coils are also classified in that Section, even if cut to length and presented with the machines (winches, teleferics, cranes, cable operated hading machines, draglines, excavators, etc.) for which they are intended. r; P P The heading also excludes : (a) Transmission or conveyor belts or belting, of plastics (Cha ter 39), of vulcanised rubber (heading 40.10), of leather (heading 42.05) or of textile materials Reading 59.10). (b) Slings (Section XI or XV). (c) Hollow drill bars and rods (heading 72.28). (d) Casing, tubing and drill pipes (headings 73.04 to 73.06). (e) Adjustable or telescopic pit props (heading 73.08). (f) Lifting hooks (heading 73.25 or 73.26). (g) Rock drilling bits and chisels, boring bits, auger bits and similar rock drilling or earth boring tools (heading 82.07). (h) Locks for passenger and goods lifts, etc. (heading 83.01). (ij) Pulleys, pulley blocks and bearing housings (heading 84.83). -
