Rhenium Powder 99.99% Purity
High-purity rhenium powder at 99.99% purity, intended for use in superalloys for aerospace turbine blades and electronics. In its unwrought powder state, it has not been shaped or processed into articles, so it falls under tariff item 8112.41.00 for 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 powder has been consolidated into bars, rods, or wire
Wrought rhenium products fall under a different tariff item than unwrought powder.
If the rhenium has been fabricated into finished articles such as turbine blades
Articles of rhenium are classified separately from unwrought forms.
If the powder is mixed with binders or other additives for a specific industrial use
Prepared mixtures for industrial use may be classified as chemical products rather than base metals.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify that the powder is not sintered or mixed into a cermet, as those are classified elsewhere under Section XV Note 4
• For aerospace end-uses, you may need an end-use certificate; consult the CBSA for any applicable documentation
• Declare the exact purity (99.99%) on the commercial invoice to support the tariff classification

Atomized Rhenium Powder - Aerospace Grade
> Gas-atomized spherical rhenium powder meeting AMS specifications for aerospace investment casting. This is unwrought rhenium in powder form, providing uniform melt characteristics for subsequent alloying.
Commercial Rhenium Powder 99.5% Purity
> Commercial-grade rhenium powder with 99.5% purity for general metallurgical research and alloy development. This is unwrought rhenium in powder form, cost-effective for R&D applications.
Discarded Rhenium Thermocouple Wire
> Discarded thermocouple wires made from tungsten-rhenium alloys, burnt out during high-temperature furnace monitoring. These wires are now scrap, with significant rhenium content, making them valuable for metal recovery and recycling.
High-Purity Rhenium Sputtering Target Powder
> Rhenium powder specifically prepared for plasma sputtering to deposit thin films in semiconductors. This is classified as unwrought powder since it is not yet formed into sputtering targets.
Nano-Rhenium Powder for Catalysis
> Nanoparticle rhenium powder with particle size less than 100nm, used as a precursor for petroleum reforming catalysts. This remains unwrought powder until supported on alumina.
Rhenium Alloying Powder for Superalloys
> Atomized rhenium powder used as a master alloy addition in nickel-based superalloys for gas turbines. This unwrought powder form is used before melting and alloying, enhancing creep resistance.
