Unwrought Iridium Ingot
A solid iridium ingot produced by melting and casting pure iridium metal, weighing typically 1 kg or more, used as raw material for further processing. Classified under HTS 7110.41.00.10 as unwrought iridium in its basic metal form, not shaped into plates, sheets, or other semimanufactured products. Meets chapter notes defining platinum group metals including iridium.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in powder form passing 0.5mm sieve
Powder form per subheading note requires 90%+ passing 0.5mm sieve, shifting to specific powder subheading within same heading.
If alloyed with osmium or ruthenium
Alloys classified with predominant PGM metal by weight per chapter note 5; if iridium not predominant, moves to other iridium/osmium/ruthenium category.
If imported as precious metal compounds
Precious metal compounds like iridium chloride fall under Chapter 26 for rare-earth compounds, not pure metal in Chapter 71.

Import Tips & Compliance
• Obtain purity certificates from accredited labs confirming >99.9% iridium content to avoid reclassification; declare exact weight and form precisely to match 'unwrought' definition
• Beware of common pitfalls like mislabeling sponge forms as powder if sieve test fails
Related Products under HTS 7110.41.00.10
Pure Iridium Sponge
Porous iridium sponge produced via chemical precipitation and reduction, serving as an intermediate form before consolidation into ingots. Falls under HTS 7110.41.00.10 as unwrought iridium, distinct from powder due to particle size exceeding subheading note's 0.5mm sieve threshold. Used in electronics and aerospace manufacturing.
Iridium Casting Grain
Small, irregular granules of pure iridium designed for melting in investment casting applications. HTS 7110.41.00.10 applies as unwrought form, not semifinished like bars or sheets, per tariff definitions excluding worked shapes. Essential for jewelry and dental alloy production.
High-Purity Iridium Pellets
Cylindrical or cubic pressed pellets of 99.99% pure iridium for electron beam evaporation in thin-film deposition. Unwrought status under HTS 7110.41.00.10 as simple compression form, not machined or rolled. Critical for semiconductor sputtering targets.
Iridium Powder Precursor Sponge
Coarse sponge fragments intended for milling into powder, classified unwrought under HTS 7110.41.00.10 since current form doesn't meet powder sieve criteria. Used in additive manufacturing and catalyst preparation.
99.999% Iridium Lump
Irregular chunks of ultra-high purity (5N) iridium from electrolysis, weighing 100g-500g each. HTS 7110.41.00.10 as unwrought pure iridium, excluding clad or plated forms per chapter notes.
Arc-Melted Iridium Button
Disc-shaped iridium mass from vacuum arc remelting, typically 50mm diameter, serving as stock for forging. Remains unwrought under HTS 7110.41.00.10 despite casting, as not semifinished profile.
