8112.41.00Discarded 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.
8112.41.00High-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.
8112.41.00Nano-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.
8112.41.00Rhenium 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.
8112.41.00Rhenium Catalyst Waste
> Spent catalyst residues from petroleum refining, impregnated with rhenium, now containing recoverable rhenium metal. These residues are classified as waste and scrap of rhenium due to their primary rhenium content and recovery value.
8112.41.00Rhenium Electronics Contact Scrap
> Stamped-out contact points from rhenium-iridium alloys used in high-reliability telecommunications switches. These are scrap from fabrication, classified as rhenium waste and scrap, and recycled into new contacts.
8112.41.00Rhenium Jet Engine Clippings
> Precision clippings and grindings from rhenium-containing single-crystal turbine blades for military aircraft engines. These are classified as rhenium waste and scrap due to their high rhenium recovery value.
8112.41.00Rhenium Medical Imaging Foil Scrap
> Quality rejects and trim scrap from rhenium foil used in CT scanner anode targets. These are classified as rhenium waste and scrap from medical device production, recovered for high-purity refoil production.
8112.41.00Rhenium 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.
8112.41.00Rhenium Plating Bath Sludge
> Precipitated sludge from electroplating baths using rhenium salts for corrosion-resistant coatings on valves. The sludge contains metallic rhenium precipitates and is classified as rhenium waste and scrap.
8112.41.00Rhenium 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.

8112.41.00Rhenium Reference Standard Powder
Certified reference material rhenium powder, NIST-traceable, for analytical calibration in spectrometry and quality control laboratories. Despite its specialized purpose, it remains an unwrought base metal powder and is classified under tariff item 8112.41.00 for unwrought rhenium, waste and scrap, and powders.
8112.41.00Rhenium Sputtering Target Scrap
> Edge trimmings and spent centers from pure rhenium sputtering targets for thin-film deposition in semiconductors. These are classified as rhenium waste and scrap with high purity suitable for target remaking.
8112.41.00Rhenium Superalloy Scrap
> Machining turnings and clippings from nickel-rhenium superalloys used in turbine blades, with rhenium as the key recovery element. These are classified as rhenium waste and scrap since rhenium content defines their value.
8112.41.00Rhenium Vacuum Tube Filament Scrap
> Scrap filaments from specialty vacuum tubes used in microwave power amplifiers, containing pure rhenium wire. These are classified as rhenium waste and scrap from electronics manufacturing, with high purity enabling direct recovery.
