Iridium Powder-Excluding Form
Iridium flakes or granules (0.5-2mm size, <90% through 0.5mm sieve) for thermal spray coatings. Excluded from powder subheading; HTS 7110.49.0050 as 'other' semimanufactured iridium.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 90%+ passes 0.5mm sieve
Explicit subheading note defines qualifying powder separately from coarser semimanufactured forms.
If mixed base metal impurities
Ruthenium/iridium residues with >50% base metals shift to Chapter 81 other metals.
If premixed coating paste
Flakes in binder become prepared coating materials under chemicals.

Import Tips & Compliance
• Sieve analysis report mandatory to prove <90% passes 0.5mm per subheading note
• Particle size distribution prevents misclassification as powder (7110.19)
• Dust explosion hazards require UN proper shipping name declaration
