Precious Metal Ores and Concentrates (Except Silver)

Gold-bearing ores and concentrates dominate this heading commercially, with the US schedule distinguishing gold-content material (2616900040), other precious-metal-content material (2616900050), and residual other-metal-content fractions (2616900070). Canada and Mexico are the leading suppliers, consistent with their roles as major gold-mining jurisdictions with established trade corridors to US smelters and refiners. Chile and Germany also appear among top sources, the latter again reflecting smelter re-export activity. Correct classification hinges on whether the material remains an ore or concentrate versus a more refined intermediate; material that has crossed into doré or refined metal territory belongs in Chapter 71.
