Unwrought Iridium Ingot
A solid ingot of high-purity iridium in unwrought form, typically cast into bars or blocks for further processing. Classified under HTS 7110.41.0050 as unwrought iridium, one of the platinum group metals, not in powder form or semimanufactured shapes like wire or plate.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in powder form with 90% passing 0.5mm sieve
Powder form iridium separates into 7110.41.0010 per subheading note 1.
If in semimanufactured form like sheet or rod
Iridium processed beyond unwrought (e.g., rolled or drawn) falls under 'other' semimanufactured.
If as platinum group metal compounds or residues
Unrefined residues or compounds of iridium/osmium/ruthenium classify in Chapter 26, not Chapter 71.

Import Tips & Compliance
• Verify purity and composition via assay certificate to confirm iridium predominance per chapter note 4
• Provide documentation proving unwrought status (not rolled, drawn, or shaped) to avoid reclassification
• Declare exact weight and form; common pitfall is mislabeling sponge as unwrought
Related Products under HTS 7110.41.00.50
Osmium Sponge (Unwrought)
Porous osmium sponge produced by chemical reduction, considered unwrought as it requires further consolidation. Falls under HTS 7110.41.0050 for unwrought osmium or ruthenium in non-powder form, per HTS definitions excluding semimanufactured shapes.
Ruthenium Casting Grain (Unwrought)
Small irregular ruthenium grains used directly for melting and casting into alloys. HTS 7110.41.0050 applies to unwrought ruthenium not in powder form, distinct from semimanufactured pellets or wire.
Recycled Osmium Unwrought Lump
Irregular lumps of refined osmium from scrap recovery, in unwrought condition for remelting. HTS 7110.41.0050 covers such 'other' unwrought platinum group metals excluding powder.
High-Purity Ruthenium Shot (Unwrought)
Small spherical ruthenium shot produced by atomization but qualifying as unwrought due to irregular form. Falls under 7110.41.0050 for unwrought ruthenium not meeting powder sieve criteria.
Unwrought Iridium-Ruthenium Alloy Bar
Cast bar alloy where ruthenium predominates over iridium and other PGMs by weight. Classified in HTS 7110.41.0050 as unwrought 'other' iridium/osmium/ruthenium per chapter note 4 classification rules.
