Gold Compounds

Gold compounds — including gold chloride, gold cyanide, gold sulfite, and organogold complexes — are critical inputs for electroplating baths, semiconductor bonding, medical diagnostics, and pharmaceutical applications such as injectable gold-based antiarthritics. Classified under a single 10-digit line (2843300000), the high intrinsic value of gold content demands rigorous valuation documentation and metal-content certification at entry. Canada and Germany are the leading US import sources, with the United Kingdom, South Korea, and Japan also among the primary suppliers. The pharmaceutical end use of certain gold compounds may bring them within FDA's purview depending on formulation and intended application.
