Inorganic & Organic Compounds of Precious Metals; Amalgams (NESOI)

Platinum-group metal compounds — including platinum chloride, palladium acetate, rhodium trichloride, and iridium salts — along with amalgams of precious metals, are captured in this residual heading when not more specifically classified elsewhere in heading 2843. These materials are essential precursors for automotive catalytic converters, pharmaceutical synthesis catalysts, and fuel cell components, making them strategically significant inputs for multiple high-technology industries. The United Kingdom and Japan are the leading US import sources, with South Africa — a dominant global producer of platinum-group metals — also among the primary suppliers. Given the high unit values involved, precise metal-content documentation and accurate valuation are essential compliance priorities.
