Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If certified as silver-rhenium contact material
Pre-mixed powders for electrical contacts may fall under Chapter 71 semi-manufactured silver.
If recovered from mining residues
Rhenium-bearing residues classify as other slag/ash, not refined unwrought metal.
If in thinner foil sheets post-pressing
Powders compacted into foil become unwrought beryllium (similar structure) but rhenium-specific.

Import Tips & Compliance
• Label containers with UN number for hazardous material shipping if nano-sized particles
• Maintain chain-of-custody documentation to prevent misclassification as scrap metal
