Alloys of precious metal are to be classified according to the following rules : (a) An alloy containing 2 % or more, by weight, of platinum is to be treated as an alloy of platinum; (b) An alloy containing 2 % or more, by weight, of gold but no platinum, or less than 2 %, by weight, of platinum, is to be treated as an alloy of gold; (c) Other alloys containing 2 % or more, by weight, of silver are to be treated as alloys of silver. 6.- Except where the context otherwise requires, any reference in the Nomenclature to precious metal or to any particular precious metal includes a reference to alloys treated as alloys of precious metal or of the particular metal in accordance with the rules in Note 5 above, but not to metal clad with precious metal or to base metal or non-metals plated with precious metal. 7.- Throughout the Nomenclature the expression “metal clad with precious metal” means material made with a base of metal upon one or more surfaces of which there is affixed by soldering, brazing, welding, hot-rolling or similar mechanical means a covering of precious metal. Except where the context otherwise requires, the expression also covers base metal inlaid with precious metal. 8.- Subject to Note 1 (A) to Section VI, goods answering to a description in heading 71.12 are to be classified in that heading and in no other heading of the Nomenclature. 9.- For the purposes of heading 71.13, the expression “articles of jewellery” means : (a) Any small objects of personal adornment (for example, rings, bracelets, necklaces, brooches, ear- rings, watch-chains, fobs, pendants, tie-pins, cuff-links, dress-studs, religious or other medals and insignia); and (b) Articles of personal use of a kind normally carried in the pocket, in the handbag or on the person (for example, cigar or cigarette cases, snuff boxes, cachou or pill boxes, powder boxes, chain purses or prayer beads).
