Subheadings
Products classified under Tariff item 7110.49.00
High-Purity Iridium Discs 50mm Diameter
High-purity iridium discs, 50mm diameter, precision-machined for sputtering targets in semiconductor manufacturing. As semi-manufactured iridium forms other than powder, they fall under this tariff item.
Iridium Bar 5mm x 20mm Cross-Section
Rectangular iridium bar with 5mm x 20mm cross-section, for machining into crucibles and electrodes. As a semi-manufactured iridium form other than unwrought or powder, it falls under this tariff item.
Iridium Foil Sheet 0.05mm Thick
Thin iridium foil rolled to 0.05mm thickness for thin-film deposition and corrosion-resistant linings. As a semi-manufactured iridium form other than powder, it falls under this tariff item.
Iridium-Ruthenium Alloy Wire
Iridium-ruthenium alloy wire in semi-manufactured form, containing 60% iridium and 40% ruthenium by weight. Since iridium predominates over ruthenium, the alloy is classified under the iridium subheading, and as a semi-manufactured form other than powder, it falls under this tariff item.
Iridium Sheet (Semi-Manufactured)
Rolled iridium sheet, 1mm thick, in semi-manufactured form for use in crucibles for semiconductor production. As a semi-manufactured iridium product other than unwrought or powder, it is classified under this tariff item.
Iridium Sponge
Iridium sponge, a porous semi-manufactured form produced by reducing iridium compounds, used in high-temperature alloys and spark plugs. Since it is not powder per the sieve test and is semi-manufactured, it falls under this tariff item.
Iridium Strip 10mm Wide x 0.2mm Thick
Rolled iridium strip, 10mm wide by 0.2mm thick, for electrical contacts and sealing rings in vacuum equipment. As a semi-manufactured iridium form other than powder, it falls under this tariff item.
Iridium Tube Hollow Stock 3mm OD
Seamless iridium tubing, 3mm outer diameter, for thermocouple sheaths and chemical reactor components. As a semi-manufactured hollow form other than powder, it falls under this tariff item.
Iridium Wire Rod 1mm Diameter
Semi-manufactured iridium wire rod drawn to 1mm diameter, suitable for further drawing into fine wires for thermocouples and electrical contacts. As a semi-manufactured iridium form other than powder, it falls under this tariff item.
Osmium Black Powder Alternative Form
Osmium black in compacted semi-manufactured pellets, not qualifying as powder per the sieve test, used in alloying. As a semi-manufactured osmium form other than powder, it falls under this tariff item.
Osmium Wire (Semi-Manufactured)
Osmium wire in semi-manufactured form, 0.5-1mm diameter, used in medical implants and electrical contacts. As a semi-manufactured osmium product other than unwrought or powder, it falls under this tariff item.
Pure Iridium Powder-Free Semimanufactured Pellet
Compressed iridium pellets in semi-manufactured form for spark erosion electrodes and additive manufacturing feedstock. Distinct from powder per the subheading note, they fall under this tariff item.
Ruthenium Discs (Semi-Manufactured)
Precision-cut ruthenium discs, 10mm diameter and 0.5mm thick, for sputtering targets. As semi-manufactured ruthenium forms other than unwrought or powder, they fall under this tariff item.
Ruthenium Foil (Thickness 0.1mm)
Thin ruthenium foil, 0.1mm thick, in semi-manufactured form for plating baths and catalyst production. As a semi-manufactured ruthenium product other than powder, it falls under this tariff item.
Ruthenium Strip for Catalysts
Ruthenium metal strip, 0.2mm x 10mm, semi-manufactured, used as a catalyst precursor in hydrogenation processes. As a semi-manufactured ruthenium form other than powder, it falls under this tariff item.
