Rhenium Metal Powder Grade A
Commercial Grade A rhenium powder at 99.9% purity, supplied in unwrought form for use in alloying applications such as electrical contacts and thermocouples. As a powder of a base metal that has not been shaped or worked into articles, it is classified under tariff item 8112.41.00, which covers unwrought rhenium, waste and scrap, and powders.

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 rhenium has been worked into plates, sheets, strip, foil, wire, bars, rods, or profiles
This alternative covers wrought rhenium products, which are distinct from unwrought powder.
If the powder is a chemical compound or mixed with non-metallic elements in a way that changes its character
Colloidal or chemical forms of rhenium may fall under inorganic chemical headings rather than base metals.

Import Tips & Compliance
• Ensure the powder meets the definition of 'powders' in Section XV Note 8(b): 90% or more by weight must pass through a 1 mm sieve
• Keep a certificate of analysis from the supplier to confirm purity and particle size distribution for CBSA
• If the powder is mixed with other metals, check Section XV Note 5 to determine if it is still classified as rhenium alloy
