Ores & Concentrates of Precious Metals Except Silver

While CBP does not impose a separate precious-metal-specific bond beyond the standard import bond, the high declared value of gold and PGM concentrates means that the continuous bond amount must be sufficient to cover potential duty and penalty exposure. Carriers and freight forwarders also typically require specialized cargo insurance and secure handling arrangements. Importers should coordinate with their customs broker and insurer well in advance of shipment.

Several major producing countries restrict or tax the export of unprocessed or partially processed precious metal concentrates to incentivize domestic refining capacity. These policies can reduce the volume of concentrates available for import into the US and shift trade flows toward refined metal or intermediate doré bars instead. Importers and offtake buyers should monitor regulatory developments in key producing jurisdictions as part of their supply-chain risk assessment.
