Products classified under HTS 7110.49.00.10
Unwrought Iridium Ingot
A solid iridium ingot in unwrought form, typically produced by melting and casting pure iridium metal, used as raw material for further processing in high-tech industries. Classified under HTS 7110.49.0010 as iridium separately in unwrought form, distinct from powder or finished semimanufactured products. Meets chapter notes defining platinum group metals including iridium.
Iridium Sponge
Porous iridium sponge produced by thermal decomposition, a semimanufactured intermediate form before final fabrication into wires or foils. Falls under HTS 7110.49.0010 as iridium separately, not powder per subheading note requiring 90% through 0.5mm sieve. Used in spark plug electrodes and crucibles.
Iridium Wire Rod 1mm Diameter
Semimanufactured iridium wire rod drawn to 1mm diameter, suitable for further drawing into fine wires for thermocouples and electrical contacts. HTS 7110.49.0010 covers iridium separately in unwrought or semimanufactured forms, excluding finished articles. Purity typically 99.95% to meet electronics specs.
Iridium Foil Sheet 0.05mm Thick
Thin iridium foil rolled to 0.05mm thickness for use in thin-film deposition and corrosion-resistant linings. Semimanufactured form under HTS 7110.49.0010 for iridium separately, as it requires further processing into finished products. High corrosion resistance ideal for chemical processing equipment.
Pure Iridium Powder-Free Semimanufactured Pellet
Compressed iridium pellets in semimanufactured form for spark erosion electrodes and additive manufacturing feedstock. Distinct from powder form per subheading note, classified under HTS 7110.49.0010 as iridium separately. Particle aggregates exceed 0.5mm sieve size.
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. HTS 7110.49.0010 applies to this unwrought/semimanufactured iridium form separately from alloys or powders. Exceptional oxidation resistance at high temperatures.
High-Purity Iridium Discs 50mm Diameter
Precision-machined iridium discs 50mm diameter for sputtering targets in semiconductor manufacturing. Semimanufactured blanks under HTS 7110.49.0010, requiring final surface finishing. Purity 99.99% for thin-film deposition applications.
Iridium Bar 5mm x 20mm Cross-Section
Rectangular iridium bar with 5mm x 20mm cross-section for machining into crucibles and electrodes. Unwrought form suitable for forging under HTS 7110.49.0010 as iridium separately. Used in superalloy melting applications.
Iridium Tube Hollow Stock 3mm OD
Seamless iridium tubing 3mm outer diameter for thermocouple sheaths and chemical reactor components. Semimanufactured hollow form under HTS 7110.49.0010, excluding finished tubes. Extreme chemical inertness for harsh environments.
99.999% Pure Iridium Grain
High-purity iridium grains (2-5mm) produced by gas atomization but sized beyond powder definition, for investment casting. HTS 7110.49.0010 as iridium separately in semimanufactured form. Five-nines purity for optical coatings.
