More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder has been pre-sintered or partially fused into shapes
Sintered or partially worked rhenium may be considered wrought rather than unwrought.
If the powder is a cermet (metal carbide sintered with a metal)
Cermets are classified under heading 81.13, not under rhenium.
If the powder is specifically for use in semiconductor or flat panel display manufacturing equipment
Parts for such equipment may be classified under Chapter 84.

Import Tips & Compliance
• Confirm the particle size distribution meets the Section XV definition of powder (90% passing a 1 mm sieve); ultrafine powders easily qualify
• For aerospace applications, be aware that rhenium may be subject to export controls in the country of origin, but Canada applies its own import controls—check with the CBSA
• Keep documentation of the powder's intended use in 3D printing to support classification as unwrought material
