Import Tips
• Comply with Section 1502 conflict minerals rules; provide smelter audits and chain-of-custody documentation
• Test for associated radioactive elements like uranium, which may require NRC licensing
• Use locked bulk bags to prevent theft, as high-value tantalum concentrates attract smuggling risks
