Metal clad with precious metal (including base metal inlaid with precious metal) is defined in Note 7 and the General Explanatory Note to this Chapter. Base metal or silver clad with gold are usually in forms similar to those described for base metal clad with silver (see the Explanatory Note to heading 71.07).
Base metal (e.g., copper and its alloys) or silver is clad with gold for the manufacture of jewellery (bracelets, watch-chains, ear-rings, etc.), watch-cases, cigar or cigarette-holders, lighters, goldsmiths' wares, electrical contacts, chemical apparatus, etc.
