Import Tips & Compliance
• Use insured shipping with tamper-evident seals; provide chain-of-custody docs
• Common issue: assay disputes—import with third-party lab seals
Related Products under HTS 7110.41.00.10
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.
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.
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.
